Subject: [PATCH 19/22] tools: Update asm-generic/mman-common.h copy from the kernel

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

To get the changes in the commit Fixes: 3209f68b3ca4 ("statx: Include a
mask for stx_attributes in struct statx")

Silencing this perf build warning:

  Warning: tools/include/uapi/linux/stat.h differs from kernel

No need to change the statx syscall beautifiers in 'perf trace' at this
time.
