3.16.7-ckt23 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: James Morse <james.morse@xxxxxxx>
commit 1d5cda4076d930d6d52088ed2c7753f7c564cbd7 upstream.
mmdebug.h uses BUILD_BUG_ON_INVALID(), assuming someone else included
linux/bug.h. Include it ourselves.
This saves build-failures such as:
arch/arm64/include/asm/pgtable.h: In function 'set_pte_at':
arch/arm64/include/asm/pgtable.h:281:3: error: implicit declaration of function 'BUILD_BUG_ON_INVALID' [-Werror=implicit-function-declaration]
VM_WARN_ONCE(!pte_young(pte),
Fixes: 02602a18c32d7 ("bug: completely remove code generated by disabled VM_BUG_ON()")
