tools/perf/trace/beauty/mmap.c, tools/perf/util/event.c and
tools/perf/util/map.c depend on several macros in mman.h, which
are lost on old systems like ubuntu 12.04. They are architecture

Not "lost on old systems", changing that to "not present on old systems"


dependened macros. Importing ./arch/*/include/uapi/asm/mman.h
into tools/ is not easy because mman.h for some unusual archs
(like tile) have extra dependencies.
This patch introduces only required macros into mman-fix.h.
Macros list is gotten from tools/perf/trace/beauty/mmap.c.

ok, I'll try keeping the  include/uapi/asm-generic/mman.h and
arch/alpha/include/uapi/asm/mman.h with just what you added, so that at
least the .c files appears as using the headers were those things are
defined in the kernel sources.

Ah, and good eyes in realizing this is not the same value for all
arches!


This is why we have to define these macros for each archs.
Your solution in tools/perf/trace/beauty/mmap.c works for
x86 only.

However, I don't like this patchset because we add 300+
lines of code and 22 new files for less than 15 macros,
and only one of them I really concern. Moreover, futhre
code require more symbols in uapi and we have to add new
headers, finally we will clone the whole uapi. We have
to stop doing this...

For the hugetlb problem, I think you can take the v2 patch
without this 2 patches:

http://lkml.kernel.org/r/1473137909-142064-1-git-send-email-wangn...@huawei.com

so old system can compile without hugetlb support.

This is the reason why I separated into 2 patch series.

Thank you.

This patch is gnerated using following bash script:

  }

  function finish_mman_fix_header()
  {
    echo "#endif // $1" >> $2
    echo "Finish writing $2"
  }

  function build_mman_fix_header()
  {
    guard=$1
    shift
    target=$1
    shift
    begin_mman_fix_header $guard $target
    for src in $@
