[PATCH 4.2.y-ckt 282/305] include/linux/mmdebug.h: should include linux/bug.h

From: Kamal Mostafa

4.2.8-ckt2 -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()")
