Subject: [PATCH] mm/vmalloc.c: remove unnecessary highmem_mask from parameter
of gfpflags_allow_blocking()
References: bnc#1155780 (VM/FS functional and performance backports)
Patch-mainline: v5.5-rc1
Git-commit: dcf61ff06d1738f66f89a54c25469df346214d75
gfpflags_allow_blocking() does not care about __GFP_HIGHMEM, so
highmem_mask can be removed.
