Subject: [PATCH 17/23] tools headers UAPI: Sync asm-generic/mman-common.h with the kernel

From: Arnaldo Carvalho de Melo <acme@...hat.com>

To pick the changes from:

  d41938d2cbee ("mm: Reserve asm-generic prot flags 0x10 and 0x20 for arch use")

No changes in tooling, just a rebuild as files needed got touched.

This addresses the following perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman-common.h' differs from latest version at 'include/uapi/asm-generic/mman-common.h'
  diff -u tools/include/uapi/asm-generic/mman-common.h include/uapi/asm-generic/mman-common.h
