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")

I have different patch which should fix this too.
It removes usage of VM_STACK_DEFAULT_FLAGS from that file.

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.
Build results in next-20160128:
total: 146 pass: 121 fail: 25
Failed builds:
alpha:allmodconfig
arm64:allnoconfig
arm64:allmodconfig
avr32:defconfig
avr32:merisc_defconfig
avr32:atngw100mkii_evklcd101_defconfig

Qemu test results:
total: 96 pass: 83 fail: 13
Failed tests:
arm:kzm:imx_v6_v7_defconfig

s390:defconfig
sparc64:sun4u:nosmp:sparc64_defconfig
sparc64:sun4v:nosmp:sparc64_defconfig
Not all, but most of the failures are due to 07dff8ae2bc5.

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