Greeting's
Today's linux-next kernel 5.3.0-rc5-next-20190820 failed to build on my powerpc machine
Build errors: drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c: In function amdgpu_exit: drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:1471:2: error: implicit declaration of function mmu_notifier_synchronize [-Werror=implicit-function-declaration] mmu_notifier_synchronize(); ^~~~~~~~~~~~~~~~~~~~~~~~ cc1: some warnings being treated as errors make[4]: *** [drivers/gpu/drm/amd/amdgpu/amdgpu_drv.o] Error 1 make[3]: *** [drivers/gpu/drm/amd/amdgpu] Error 2
It was introduced with commit c7d8b7 (hmm: use mmu_notifier_get/put for 'struct hmm')
Reverting the commit fixes the issue.
