To pick the changes from:
1a4e58cce84e ("mm: introduce MADV_PAGEOUT")
9c276cc65a58 ("mm: introduce MADV_COLD")
That result in these changes in the tools:

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'
