mm, page_alloc: print symbolic gfp_flags on allocation failure

Browse source

It would be useful to translate gfp_flags into string representation
when printing in case of an allocation failure, especially as the flags
have been undergoing some changes recently and the script
./scripts/gfp-translate needs a matching source version to be accurate.

Example output:

  stapio: page allocation failure: order:9, mode:0x2080020(GFP_ATOMIC)
