Subject: m68k compile issue with 4.0.5

Hi,

I am trying to build a M68K (Coldfire no-MMU) kernel for Qemu-system-m68k.

With 4.0.4 everything is fine. With 4.0.5 I get following compile
error:
  adk-uclinux-gcc -Wp,-MD,mm/.nommu.o.d  -nostdinc -isystem
/home/wbx/m68k/toolchain_qemu-m68k_uclibc-ng_m68k_nommu/usr/lib/gcc/m68k-openadk-uclinux-uclibc/4.9.2/include

[-Werror=implicit-function-declaration]
   vma_fput(vma);
   ^
cc1: some warnings being treated as errors

Any idea what change breaks the compile?

best regards
 Waldemar
