To pick the changes from:

Fixes: 4ca9b385 ("mm/madvise: introduce MADV_POPULATE_(READ|WRITE) to prefault page tables")

That result in these changes in the tools:

I.e. now when madvise gets those behaviours as args, it will be able to
translate from the number to a human readable string.

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'
