Subject: include/linux/mmdebug.h: should include linux/bug.h
X-Git-Tag: firefly_0821_release~176^2~546^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1d5cda4076d930d6d52088ed2c7753f7c564cbd7;p=firefly-linux-kernel-4.4.55.git

include/linux/mmdebug.h: should include linux/bug.h

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()")
