[PATCHSET 00/11] perf tools: Sync tools and kernel headers for v6.13

[PATCHSET 00/11] perf tools: Sync tools and kernel headers for v6.13

[Namhyung Kim]

Hello,

I'll carry these changes on the perf tools tree to update perf tools to
understand new syscalls and parameters.  You can refer to README file in
the tools/include/uapi directory why it's needed.

Thanks,
Namhyung

[PATCH 11/11] perf tools: Fix build error on generated/fs_at_flags_array.c

[Namhyung Kim]

It should only have generic flags in the array but the recent header
sync brought a new flags to fcntl.h and caused a build error.  Let's
update the shell script to exclude flags specific to name_to_handle_at().

Hi Namhyung,

Is it possible to fix this before the updates to keep it buildable? 
Maybe it's not feasible, I didn't check.

I did notice a build issue in the kvm tests after this update:

$ make O=../build/local/ summary=1 TARGETS=kvm kselftest

In file included from aarch64/aarch32_id_regs.c:14:
include/aarch64/processor.h:15:10: fatal error: asm/brk-imm.h: No such 
file or directory
    15 | #include <asm/brk-imm.h>

But I tried the same on v6.13-rc1 and got a different error, so I don't 
know if it's any worse.

Thanks
James

I suspect it's an unrelated issue.  This fix is about generating
descriptions of the flags for perf trace beautifier.

The below is the only change I made in this series for arm64.

Thanks,
