mm, oom: print symbolic gfp_flags in oom warning
It would be useful to translate gfp_flags into string representation
when printing in case of an OOM, 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:
a.out invoked oom-killer: gfp_mask=0x24280ca(GFP_HIGHUSER_MOVABLE|GFP_ZERO), order=0, om_score_adj=0
