radeon driver warning

[John Garry]

Hi guys,

This warning in the radeon driver breaks my randconfig build on v5.19-rc2:

drivers/gpu/drm/radeon/radeon_object.c:186:2: error: #warning Please 
enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to 
write-combining [;;https://gcc.gnu.org/onl
inedocs/gcc/Warning-Options.html#index-Wcpp-Werror=cpp;;]

Is anything being done to fix it? I don't see anything in -next or on 
dridevel list recently which it could be.

thanks,
John
