blackfin defconfig fails with the error:
mm/internal.h: In function 'is_stack_mapping':
arch/blackfin/include/asm/page.h:15:27: error: 'READ_IMPLIES_EXEC' undeclared

Commit 07dff8ae2bc5 has added is_stack_mapping in mm/internal.h but it
also needs personality.h.

Fixes: 07dff8ae2bc5 ("mm: warn about VmData over RLIMIT_DATA")

FWIW, this is just one of many build failures due to this patch.
Pretty much all non-MMU builds fail, plus several MMU builds.
I had prepared a patch for mn10300, but gave up after I noticed
all the other failures.

Please try mine "[PATCH] mm: polish virtual memory accounting"
instead of that. It should fix some (or all) fails from 07dff8ae2bc5.

Not all, but most of the failures are due to 07dff8ae2bc5.
