Subject: linux-next: build failure after merge of the tmem tree

Hi Konrad,

After merging the tmem tree, today's linux-next build (x86_64
allmodconfig) failed like this:

mm/frontswap.c: In function 'frontswap_shrink':
mm/frontswap.c:217:3: error: implicit declaration of function 'security_vm_enough_memory_kern' [-Werror=implicit-function-declaration]

Caused by commit 8174e70a6bde ("mm: frontswap: core frontswap
functionality") interacting with commit 191c542442fd ("mm: collapse
security_vm_enough_memory() variants into a single function") from the
security tree.

I applied the following merge fix:
