True. The 0 check got lost. I'll make sure we do the right thing for
the next version.

Well, as of this patch this actually is a no-op for everyone.
Linus, what do you think of applying this patch (maybe with a slightly
fixed up commit log) to 5.2-rc so that we remove a cross dependency
between the series?

* [PATCH] powerpc/configs: Remove useless UEVENT_HELPER_PATH
From: Krzysztof Kozlowski @ 2019-06-04 8:00 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman,
linuxppc-dev, linux-kernel
Cc: Krzysztof Kozlowski, Geert Uytterhoeven
Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
made default to 'n',
2. It is not recommended (help message: "This should not be used today
[...] creates a high system load") and was kept only for ancient
userland,
3. Certain userland specifically requests it to be disabled (systemd
README: "Legacy hotplug slows down the system and confuses udev").

* [PATCH] mm/mmap: Move common defines to mman-common.h
From: Aneesh Kumar K.V @ 2019-06-04 9:09 UTC (permalink / raw)
To: akpm; +Cc: sparclinux, linux-mm, linuxppc-dev, linux-kernel,
Aneesh Kumar K.V
Two architecture that use arch specific MMAP flags are powerpc and sparc.
We still have few flag values common across them and other architectures.
Consolidate this in mman-common.h.
Also update the comment to indicate where to find HugeTLB specific reserved
values

* [PATCH v3 1/6] nvdimm: Consider probe return -EOPNOTSUPP as success
From: Aneesh Kumar K.V @ 2019-06-04 9:13 UTC (permalink / raw)
To: dan.j.williams; +Cc: linux-mm, linuxppc-dev, Aneesh Kumar K.V, linux-nvdimm
With following patches we add EOPNOTSUPP as return from probe callback to
indicate we were not able to initialize a namespace due to pfn superblock
feature/version mismatch. We want to consider this a probe success so that
we can create new namesapce seed and there by avoid marking the failed
namespace as the seed namespace.

This allows us to make changes in a backward incompatible way. I have
kept the PFN_MIN_VERSION in this patch '0' because we are not introducing
any incompatible changes in this patch. We also may want to backport this
to older kernels.
The error looks like
dax0.1: init failed, superblock min version 1, kernel support version 0
and the namespace is marked disabled
$ndctl list -Ni

* [PATCH v3 6/6] mm/nvdimm: Use correct alignment when looking at first pfn from a region
From: Aneesh Kumar K.V @ 2019-06-04 9:13 UTC (permalink / raw)
To: dan.j.williams; +Cc: linux-mm, linuxppc-dev, Aneesh Kumar K.V, linux-nvdimm
In-Reply-To: <20190604091357.32213-1-aneesh.kumar@linux.ibm.com>
We already add the start_pad to the resource->start but fails to section
align the start. This make sure with altmap we compute the right first
pfn when start_pad is zero and we are doing an align down of start address.
vmem_altmap_offset() adjust the section aligned base_pfn offset.
So we need to make sure we account for the same when computing base_pfn.
ie, for altmap_valid case, our pfn_first should be:
pfn_first = altmap->base_pfn + vmem_altmap_offset(altmap);

* [PATCH v3 5/6] mm/nvdimm: Pick the right alignment default when creating dax devices
From: Aneesh Kumar K.V @ 2019-06-04 9:13 UTC (permalink / raw)
To: dan.j.williams; +Cc: linux-mm, linuxppc-dev, Aneesh Kumar K.V, linux-nvdimm
In-Reply-To: <20190604091357.32213-1-aneesh.kumar@linux.ibm.com>
Allow arch to provide the supported alignments and use hugepage alignment only
if we support hugepage. Right now we depend on compile time configs whereas this
patch switch this to runtime discovery.
Architectures like ppc64 can have THP enabled in code, but then can have
hugepage size disabled by the hypervisor. This allows us to create dax devices
with PAGE_SIZE alignment in this case.
Existing dax namespace with alignment larger than PAGE_SIZE will fail to
initialize in this specific case. We still allow fsdax namespace initialization.
With respect to identifying whether to enable hugepage fault for a dax device,
if THP is enabled during compile, we default to taking hugepage fault and in dax
fault handler if we find the fault size > alignment we retry with PAGE_SIZE
fault size.
This also addresses the below failure scenario on ppc64

* [PATCH v3 3/6] mm/nvdimm: Add page size and struct page size to pfn superblock
From: Aneesh Kumar K.V @ 2019-06-04 9:13 UTC (permalink / raw)
To: dan.j.williams; +Cc: linux-mm, linuxppc-dev, Aneesh Kumar K.V, linux-nvdimm
In-Reply-To: <20190604091357.32213-1-aneesh.kumar@linux.ibm.com>
This is needed so that we don't wrongly initialize a namespace
which doesn't have enough space reserved for holding struct pages
with the current kernel.
We also increment PFN_MIN_VERSION to make sure that older kernel
won't initialize namespace created with newer kernel.

This is a good point. My understanding is that those orphaned docs
are there for two reasons:
1) someone created a new document as .rst but there's no index.rst file yet,
as there are lots of other documents already there not converted. That's
the case, for example, of the ones under Documentation/arm;
2) They're part of an undergoing effort of converting stuff to ReST.
One opted to keep it orphaned temporarily in order to avoid merge
conflicts.
That's said, I have myself a big (/86 patches and growing) series
with do a huge step on txt->rst conversion (it covers a significant
amount of documentation). On this series, I'm removing the orphaned
tags for several files (including, for example, those at Documentation/arm).
Yet, it is a lot easier to see if such series is not introducing
warnings regressions if we first address those.
It should be notice that discovering the orphaned files should be as
simple as:
git grep -l ":orphan:" Documentation

* [PATCH 05/15] kbuild: add CONFIG_HEADERS_INSTALL and loosen the dependency of samples

Commit 5318321d367c ("samples: disable CONFIG_SAMPLES for UML") used
a big hammer to fix the build errors under the samples/ directory,
while only some samples actually include uapi headers from usr/include.
Introduce CONFIG_HEADERS_INSTALL since 'depends on HEADERS_INSTALL' is
clearer than 'depends on !UML'. If this option is enabled, uapi headers
are installed before starting directory descending.
I added 'depends on HEADERS_INSTALL' to per-sample CONFIG options.
This allows UML to compile some samples.

* [PATCH 00/15] kbuild: refactor headers_install and support compile-test of UAPI headers
From: Masahiro Yamada @ 2019-06-04 10:13 UTC (permalink / raw)
To: linux-kbuild
Cc: Song Liu, linux-doc, Palmer Dabbelt, Heiko Carstens,

Multiple people have suggested to compile-test UAPI headers.
Currently, Kbuild provides simple sanity checks by headers_check
but they are not enough to catch bugs.
The most recent patch I know is David Howells' work:
https://patchwork.kernel.org/patch/10590203/
I agree that we need better tests for UAPI headers,
but I want to integrate it in a clean way.
The idea that has been in my mind is to compile each header
to make sure the selfcontainedness.
Recently, Jani Nikula proposed a new syntax 'header-test-y'.
https://patchwork.kernel.org/patch/10947005/
So, I implemented UAPI compile-testing on top of that.
When adding a new feature, cleaning the code first is a
good practice.
[1] Remove headers_install_all
This target installs UAPI headers of all architectures
in a single tree.
It does not make sense to compile test of headers from
multiple arches at the same time. Hence, removed.
[2] Split header installation into 'make headers' and 'make headers_install'
To compile-test UAPI headers, we need a work-directory somewhere
to save objects and .*.cmd files.
usr/include/ will be the work-directory.
Since we cannot pollute the final destination of headers_install,
I split the header installation into two stages.
'make headers' will build up
the ready-to-install headers in usr/include,
which will be also used as a work-directory for the compile-test.
'make headers_install' will copy headers
from usr/include to $(INSTALL_HDR_PATH)/include.
[3] Support compile-test of UAPI headers
This is implemented in usr/include/Makefile
Jani Nikula (1):
kbuild: add support for ensuring headers are self-contained
Masahiro Yamada (14):
kbuild: remove headers_{install,check}_all
kbuild: remove stale dependency between Documentation/ and
headers_install
kbuild: make gdb_script depend on prepare0 instead of prepare
kbuild: fix Kconfig prompt of CONFIG_HEADERS_CHECK
kbuild: add CONFIG_HEADERS_INSTALL and loosen the dependency of
samples
kbuild: remove build_unifdef target in scripts/Makefile
kbuild: build all prerequisite of headers_install simultaneously
kbuild: add 'headers' target to build up ready-to-install uapi headers
kbuild: re-implement Makefile.headersinst without directory descending
kbuild: move hdr-inst shorthand to top Makefile
kbuild: simplify scripts/headers_install.sh
kbuild: deb-pkg: do not run headers_check
fixup: kbuild: add support for ensuring headers are self-contained
kbuild: compile test UAPI headers to ensure they are self-contained

This latter patch has been fixed in today's linux-next ...

Indeed. Yet, seeking for the API documented there:
$ git grep -l pkey_mprotect
Documentation/x86/protection-keys.rst
arch/alpha/kernel/syscalls/syscall.tbl

tools/testing/selftests/x86/protection_keys.c
Despite being used on several archs, the only documentation for it
is inside the x86 directory, as it seems that this is not
arch-specific.
Perhaps the file should, instead, be moved to another book.
Thanks,
Mauro

I guess the best is to have this inside the core-api book.
Patch enclosed.

[PATCH] docs: move protection-keys.rst to the core-api book
This document is used by multiple architectures:
$ echo $(git grep -l pkey_mprotect arch|cut -d'/' -f 2|sort|uniq)
alpha arm arm64 ia64 m68k microblaze mips parisc powerpc s390 sh sparc x86 xtensa
So, let's move it to the core book and adjust the links to it
accordingly.

* [PATCH] ocxl: do not use C++ style comments in uapi header
From: Masahiro Yamada @ 2019-06-04 11:16 UTC (permalink / raw)
To: Frederic Barrat, Andrew Donnellan, linuxppc-dev
Cc: Arnd Bergmann, Greg KH, Randy Dunlap, linux-kernel,

Linux kernel tolerates C++ style comments these days. Actually, the
SPDX License tags for .c files start with //.
On the other hand, uapi headers are written in more strict C, where
the C++ comment style is forbidden.
