Hi All,
The latest mainline kernel branch fails to build powerpc allmodconfig
with the error:
drivers/gpu/drm/ttm/ttm_pool.c:73:29: error: variably modified
'global_write_combined' at file scope
73 | static struct ttm_pool_type global_write_combined[TTM_DIM_ORDER];

git bisect pointed to 322458c2bb1a ("drm/ttm: Reduce the number of used
allocation orders for TTM pages")
I will be happy to test any patch or provide any extra log if needed.
