Hi Ingo,
Please consider pulling, this is based on 5.2-rc1+, to cope with
9c8ad7a2ff0b ("uapi, x86: Fix the syscall numbering of the mount API
syscalls [ver #2]"), as that wasn't in tip/perf/urgent at the time.
Best regards,
- Arnaldo

tools headers UAPI: Sync kvm.h headers with the kernel sources (2019-05-27 11:05:32 -0300)
----------------------------------------------------------------
perf/urgent fixes:
BPF:
Jiri Olsa:
- Fixup determination of end of kernel map, to avoid having BPF programs,
that are after the kernel headers and just before module texts mixed up in
the kernel map.
- Preserve eBPF maps when loading kcore.
- Fix up DSO name padding in 'perf script --call-trace', as BPF DSO names are
much larger than what we used to have there.
- Add --show-bpf-events to 'perf script'.
tools UAPI header copies:
Arnaldo Carvalho de Melo:
- Update copy of files related to new fspick, fsmount, fsconfig, fsopen,
move_mount and open_tree syscalls.
- Sync cpufeatures.h, sched.h, fs.h, drm.h, i915_drm.h and kvm.h headers.
perf trace:
Arnaldo Carvalho de Melo:
- Add string table generators and beautify arguments for the new fspick,
fsmount, fsconfig, fsopen, move_mount and open_tree syscalls, as well
as new values for arguments of clone and sync_file_range syscalls.
perf version:
Arnaldo Carvalho de Melo:
- Append 12 git SHA chars to the version string.
Namespaces:
Namhyung Kim:
- Add missing byte swap ops for namespace events when processing records from
perf.data files that could have been recorded in a arch with a different
endianness.
- Add missing --namespaces option to 'perf top', to generate and process
namespace events, just like present for 'perf record'.
- Fix access to the thread namespaces list by using the namespaces_lock.
perf data:
Shawn Landden:
- Fix 'strncat may truncate' build failure with recent gcc.
Intel PT:
Andrian Hunter:
- Fix itrace defaults for 'perf script', not using the 'use_browser' variable
to figure out what options are better for 'script' and 'report'
- Allow root fixing up buildid cache permissions in the perf-with-kcore.sh
script when sharing that cache with another user.
s/390
Thomas Richter:
- Fix s390 missing module symbol and warning for non-root users in 'perf record'.
arm64:
Vitaly Chikunov:
- Fix mksyscalltbl when system kernel headers are ahead of the kernel.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Michael reported an issue with perf bench numa failing with binding to
cpu0 with '-0' option.
# perf bench numa mem -p 3 -t 1 -P 512 -s 100 -zZcm0 --thp 1 -M 1 -ddd
# Running 'numa/mem' benchmark:
# Running main, "perf bench numa numa-mem -p 3 -t 1 -P 512 -s 100 -zZcm0 --thp 1 -M 1 -ddd"
binding to node 0, mask: 0000000000000001 => -1
perf: bench/numa.c:356: bind_to_memnode: Assertion `!(ret)' failed.
Aborted (core dumped)
This happens when the cpu0 is not part of node0, which is the benchmark
assumption and we can see that's not the case for some powerpc servers.
Using correct node for cpu0 binding.

From: Arnaldo Carvalho de Melo <acme@redhat.com>
The code to disassemble BPF programs uses binutil's disassembling
routines, and those use in turn fprintf to print to a memstream FILE,
adding a newline at the end of each line, which ends up confusing the
TUI routines called from:
annotate_browser__write()
annotate_line__write()
annotate_browser__printf()
ui_browser__vprintf()
SLsmg_vprintf()
The SLsmg_vprintf() function in the slang library gets confused with the
terminating newline, so make the disasm_line__parse() function that
parses the lines produced by the BPF specific disassembler (that uses
binutil's libopcodes) and the lines produced by the objdump based
disassembler used for everything else (and that doesn't adds this
terminating newline) trim the end of the line in addition of the
beginning.
This way when disasm_line->ops.raw, i.e. for instructions without a
special scnprintf() method, we'll not have that \n getting in the way of
filling the screen right after the instruction with spaces to avoid
leaving what was on the screen before and thus garbling the annotation
screen, breaking scrolling, etc.

From: Adrian Hunter <adrian.hunter@intel.com>
Threads synthesized from /proc have comms with a start time of zero, and
not marked as "exec". Currently, there can be 2 such comms. The first is
created by processing a synthesized fork event and is set to the
parent's comm string, and the second by processing a synthesized comm
event set to the thread's current comm string.
In the absence of an "exec" comm, thread__exec_comm() picks the last
(oldest) comm, which, in the case above, is the parent's comm string.
For a main thread, that is very probably wrong. Use the second-to-last
in that case.
This affects only db-export because it is the only user of
thread__exec_comm().
Example:
$ sudo perf record -a -o pt-a-sleep-1 -e intel_pt//u -- sleep 1
$ sudo chown ahunter pt-a-sleep-1
Before:
$ perf script -i pt-a-sleep-1 --itrace=bep -s tools/perf/scripts/python/export-to-sqlite.py pt-a-sleep-1.db branches calls
$ sqlite3 -header -column pt-a-sleep-1.db 'select * from comm_threads_view'

From: He Zhe <zhe.he@windriver.com>
The buffer containing the string used to set cpumask is overwritten at
the end of the string later in cpu_map__snprint_mask due to not enough
memory space, when there is only one cpu.
And thus causes the following failure:
$ perf ftrace ls
failed to reset ftrace
$
This patch fixes the calculation of the cpumask string size.

cpu_map__snprint_mask() would write to illegal memory pointed by
zalloc(0) when there is only one cpu.
This patch fixes the calculation and adds sanity check against the input

These paths point to the wrong location but still work because they get
picked up by a -I flag that happens to direct to the correct file. Fix
paths to point to the correct location without -I flags.

From: Thomas Richter <tmricht@linux.ibm.com>
On s390 the modules loaded in memory have the text segment located after
the GOT and Relocation table. This can be seen with this output:
[root@m35lp76 perf]# fgrep qeth /proc/modules
qeth 151552 1 qeth_l2, Live 0x000003ff800b2000
...
[root@m35lp76 perf]# cat /sys/module/qeth/sections/.text
0x000003ff800b3990
[root@m35lp76 perf]#
There is an offset of 0x1990 bytes. The size of the qeth module is
151552 bytes (0x25000 in hex).
The location of the GOT/relocation table at the beginning of a module is
unique to s390.
commit 203d8a4aa6ed ("perf s390: Fix 'start' address of module's map")
adjusts the start address of a module in the map structures, but does
not adjust the size of the modules. This leads to overlapping of module
maps as this example shows:
[root@m35lp76 perf] # ./perf report -D
0 0 0xfb0 [0xa0]: PERF_RECORD_MMAP -1/0: [0x3ff800b3990(0x25000)
@ 0]: x /lib/modules/.../qeth.ko.xz
0 0 0x1050 [0xb0]: PERF_RECORD_MMAP -1/0: [0x3ff800d85a0(0x8000)
@ 0]: x /lib/modules/.../ip6_tables.ko.xz
The module qeth.ko has an adjusted start address modified to b3990, but
its size is unchanged and the module ends at 0x3ff800d8990. This end
address overlaps with the next modules start address of 0x3ff800d85a0.
When the size of the leading GOT/Relocation table stored in the
beginning of the text segment (0x1990 bytes) is subtracted from module
qeth end address, there are no overlaps anymore:
0x3ff800d8990 - 0x1990 = 0x0x3ff800d7000
which is the same as
0x3ff800b2000 + 0x25000 = 0x0x3ff800d7000.
To fix this issue, also adjust the modules size in function
arch__fix_module_text_start(). Add another function parameter named size
and reduce the size of the module when the text segment start address is
changed.
Output after:
0 0 0xfb0 [0xa0]: PERF_RECORD_MMAP -1/0: [0x3ff800b3990(0x23670)
@ 0]: x /lib/modules/.../qeth.ko.xz
0 0 0x1050 [0xb0]: PERF_RECORD_MMAP -1/0: [0x3ff800d85a0(0x7a60)

From: Thomas Richter <tmricht@linux.ibm.com>
During execution of command 'perf top' the error message:
Not enough memory for annotating '__irf_end' symbol!)
is emitted from this call sequence:
__cmd_top
perf_top__mmap_read
perf_top__mmap_read_idx
perf_event__process_sample
hist_entry_iter__add
hist_iter__top_callback
perf_top__record_precise_ip
hist_entry__inc_addr_samples
symbol__inc_addr_samples
symbol__get_annotation
symbol__alloc_hist
In this function the size of symbol __irf_end is calculated. The size of
a symbol is the difference between its start and end address.
When the symbol was read the first time, its start and end was set to:
symbol__new: __irf_end 0xe954d0-0xe954d0
which is correct and maps with /proc/kallsyms:
root@s8360046:~/linux-4.15.0/tools/perf# fgrep _irf_end /proc/kallsyms
0000000000e954d0 t __irf_end
root@s8360046:~/linux-4.15.0/tools/perf#
In function symbol__alloc_hist() the end of symbol __irf_end is
symbol__alloc_hist sym:__irf_end start:0xe954d0 end:0x3ff80045a8
which is identical with the first module entry in /proc/kallsyms
This results in a symbol size of __irf_req for histogram analyses of
70334140059072 bytes and a malloc() for this requested size fails.
The root cause of this is function
__dso__load_kallsyms()
+-> symbols__fixup_end()
Function symbols__fixup_end() enlarges the last symbol in the kallsyms
map:
# fgrep __irf_end /proc/kallsyms
0000000000e954d0 t __irf_end
#
to the start address of the first module:
# cat /proc/kallsyms | sort | egrep ' [tT] '
....
0000000000e952d0 T __security_initcall_end
0000000000e954d0 T __initramfs_size
0000000000e954d0 t __irf_end
000003ff800045a8 T fc_get_event_number [scsi_transport_fc]
000003ff800045d0 t store_fc_vport_disable [scsi_transport_fc]
000003ff800046a8 T scsi_is_fc_rport [scsi_transport_fc]
000003ff800046d0 t fc_target_setup [scsi_transport_fc]
On s390 the kernel is located around memory address 0x200, 0x10000 or
0x100000, depending on linux version. Modules however start some- where
around 0x3ff xxxx xxxx.
This is different than x86 and produces a large gap for which histogram
allocation fails.
Fix this by detecting the kernel's last symbol and do no adjustment for
it. Introduce a weak function and handle s390 specifics.

From: Jin Yao <yao.jin@linux.intel.com>
The events defined in pmu-events JSON are parsed and added into perf
tool. For fixed counters, we handle the encodings between JSON and perf
by using a static array fixed[].
But the fixed[] has missed an important event "cpu_clk_unhalted.core".
For example, on the Tremont platform,
[root@localhost ~]# perf stat -e cpu_clk_unhalted.core -a
event syntax error: 'cpu_clk_unhalted.core'
\___ parser error
With this patch, the event cpu_clk_unhalted.core can be parsed.
[root@localhost perf]# ./perf stat -e cpu_clk_unhalted.core -a -vvv

Hi Ingo/Thomas,
Please consider pulling, mostly small fixes, just one extra
header copied due to linux/fs.h now having parts of it moved to
linux/fscrypt.h that then needs syncing so that tooling continues to
build on older systems.
Best regards,
- Arnaldo

perf annotate: Don't return -1 for error when doing BPF disassembly (2019-09-30 17:30:06 -0300)
----------------------------------------------------------------
perf/urgent fixes:
perf script:
Andi Kleen:
- Fix recovery from LBR/binary mismatch in the "brstackinsn" --field.
perf annotate:
Arnaldo Carvalho de Melo:
- Propagate errors so that meaningful messages can be presented to the
user in case of problems.
perf map:
Steve MacLean:
- Fix handling of maps partially overlapped, resolving symbols in the
ranges not replaced by new mmaps.
perf tests:
Ian Rogers:
- Use raise() instead of NULL derefs to avoid causing a SIGILL rather than a
SIGSEGV for optimized builds that turn NULL derefs into ud2 instructions.
perf LLVM:
Ian Rogers:
- Don't access out-of-scope array.
perf inject:
Steve MacLean:
- Fix JIT_CODE_MOVE filename, that was having a u64 truncaded into a 32-bit
snprintf format and also a missing ".so" suffix in another case.
libsubcmd:
Ian Rogers:
- Make _FORTIFY_SOURCE defines dependent on the feature, avoiding
false positives with with memory sanitizers such as LLVM's ASan.
Vendor specific events:
Intel:
Andi Kleen:
- Fix period for Intel fixed counters.
s390:
Thomas Richter (2):
- Fix some event details transaction for machine type 8561.
tools headers UAPI:
Arnaldo Carvalho de Melo:
- Sync headers with the kernel, catching new usbdevfs ioctls and
madvise behaviours to properly decode in 'perf trace' output.
Documentation:
Steve MacLean:
- Correct and clarify jitdump spec.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

perf hists: Fix variable name's inconsistency in hists__for_each() macro (2019-12-20 18:58:13 -0300)
----------------------------------------------------------------
perf/urgent fixes:
perf report/top:
Arnaldo Carvalho de Melo:
- Fix popup menu for entries in main kernel maps other than the main one,
e.g. ".init.text", where a non-initialized pointer was causing segfaults.
Jin Yao:
- Fix incorrectly added dimensions when switching perf.data file to another
via the popup menu.
libtraceevent:
Hewenliang:
- Fix memory leakage in filter_event().
perf hists:
Yuya Fujita:
- Fix variable name's inconsistency in hists__for_each() macro.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when due to:
`.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o
OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.
With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:
bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
.type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY

perf llvm: Fix script used to obtain kernel make directives to work with new kbuild (2020-02-14 10:06:00 -0300)
----------------------------------------------------------------
perf/urgent fixes:
BPF:
Arnaldo Carvalho de Melo:
- Fix script used to obtain kernel make directives to work with new kbuild
used for building BPF programs.
maps:
Jiri Olsa:
- Fixup kmap->kmaps backpointer in kernel maps.
arm64:
John Garry:
- Add arm64 version of get_cpuid() to get proper, arm64 specific output from
'perf list' and other tools.
perf top:
Kim Phillips:
- Update kernel idle symbols so that output in AMD systems is in line with
other systems.
perf stat:
Kim Phillips:
- Don't report a null stalled cycles per insn metric.
tools headers:
Arnaldo Carvalho de Melo:
- Sync tools/ headers with the kernel sources to get things like syscall
numbers and new arguments so that 'perf trace' can decode and use them in
tracepoint filters, e.g. prctl's new PR_{G,S}ET_IO_FLUSHER options.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when due to:
`.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o
OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.
With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:
bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
.type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

Test results at the end of this message, as usual.
Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when due to:
`.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o
OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.
With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:
bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
.type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

tools arch kvm: Sync kvm headers with the kernel sources (2020-07-17 09:39:16 -0300)
----------------------------------------------------------------
Third batch of perf tooling fixes for 5.8:
- Update hashmap.h from libbpf and kvm.h from x86's kernel UAPI,
silencing build warnings.
- Set opt->set in libsubcmd's OPT_CALLBACK_SET(). Fixes
'perf record --switch-output-event event-name' usage.
