Hi all,

After merging the amdgpu tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpu/drm/amd/amdgpu/psp_v11_0.c: In function 'psp_v11_0_memory_training':
drivers/gpu/drm/amd/amdgpu/psp_v11_0.c:1047:9: error: implicit declaration of function 'vmalloc'; did you mean 'kvmalloc'? [-Werror=implicit-function-declaration]
 1047 |   buf = vmalloc(sz);
      |         ^~~~~~~
      |         kvmalloc
drivers/gpu/drm/amd/amdgpu/psp_v11_0.c:1047:7: warning: assignment to 'void *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
 1047 |   buf = vmalloc(sz);
      |       ^
drivers/gpu/drm/amd/amdgpu/psp_v11_0.c:1057:4: error: implicit declaration of function 'vfree'; did you mean 'kvfree'? [-Werror=implicit-function-declaration]

      |    ^~~~~
      |    kvfree

Caused by commit
