Browse Source 
To get the changes in:

  e346b38130 ("mm/mremap: add MREMAP_DONTUNMAP to mremap()")

Add that to 'perf trace's mremap 'flags' decoder.

This silences this perf build warning:

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