Arnaldo Carvalho de MeloandNamhyung Kim 7f8969aa73 perf beauty: Move copy of fadvise.h from tools/include/ to tools/perf/trace/beauty/include/ 
As it is not really used when compiling anything, just being parsed to
collect number->string tables for 'perf trace'.

  $ git grep fadvise.h tools/
  tools/perf/Makefile.perf:$(fadvise_advice_array): $(beauty_uapi_linux_dir)/fadvise.h $(fadvise_advice_tbl)
  tools/perf/check-headers.sh:  "include/uapi/linux/fadvise.h"
  tools/perf/trace/beauty/fadvise.sh:grep -E $regex ${header_dir}/fadvise.h | \
  tools/perf/trace/beauty/fadvise.sh:# tools/include/uapi/linux/fadvise.h for details.

Arnaldo Carvalho de MeloandNamhyung Kim a8e11416ff perf beauty: Move tools/include/uapi/drm to tools/perf/trace/beauty/include/uapi 
As it is used only to parse ioctl numbers, not to build perf and so far
no other tools/ living tool uses it, so to clean up tools/include/ to be
used just for building tools, to have access to things available in the
kernel and not yet in the system headers, move it to the directory where
just the tools/perf/trace/beauty/ scripts can use to generate tables
used by perf.

Leo YanandArnaldo Carvalho de Melo 81f86728a9 tools headers: Skip arm64 cputype.h check 
Some definitions in the arm64 kernel's cputype.h are kernel specific and
cause perf build failures when the header is synced into tools.

Stop checking arm64's cputype.h.  In the future, the header in tools
will be updated manually when teaching tools about new CPUs.

Leo YanandArnaldo Carvalho de Melo 9966b382d0 tools headers: Don't check arm64's unistd.h 
The arm64 unistd.h in tools now diverges from the kernel header.
Comparing the two headers is pointless, remove the check.

Ian RogersandArnaldo Carvalho de Melo f0015d8149 tools include: Add headers to make tools builds more hermetic 
tools/lib/bpf/netlink.c depends on rtnetlink.h and genetlink.h (via
nlattr.h) which then depends on if_addr.h.

tools/bpf/bpftool/link.c depends on netfilter_arp.h which then depends
on netfilter.h.

Update check-headers.sh to keep these in sync.

Ian RogersandArnaldo Carvalho de Melo 57a64919f2 tools include: Replace tools linux/gfp_types.h with kernel version 
Previously the header gfp_types.h in tools points to the gfp_types.h
in include/linux. This is a problem for tools like perf, since the
tools header is supposed to be independent of the kernel
headers.

Therefore this patch copies the kernel header to the tools header and
adds a header check.

Charlie JenkinsandArnaldo Carvalho de Melo 4a73aff8c5 perf tools: Create generic syscall table support 
Currently each architecture in perf independently generates syscall
headers.

Adapt the work that has gone into unifying syscall header
implementations in the kernel to work with perf tools.

Introduce this framework with riscv at first. riscv previously relied on
libaudit, but with this change, perf tools for riscv no longer needs
this external dependency.

Arnaldo Carvalho de Melo 55f1b540d8 tools headers: Update the linux/unaligned.h copy with the kernel sources 
To pick up the changes in:

  7f053812da ("random: vDSO: minimize and simplify header includes")

That required adding a copy of include/vdso/unaligned.h and its checking
in tools/perf/check-headers.h.

Addressing this perf tools build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/include/linux/unaligned.h include/linux/unaligned.h

Please see tools/include/uapi/README for further details.

Al Viro 5f60d5f6bb move asm/unaligned.h to linux/unaligned.h 
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.
