6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicholas Kazlauskas nicholas.kazlauskas@amd.com
[ Upstream commit 31663521ede2edb622ee1b397ae3ac666d6351c5 ]
[Why] It's currently hard coded to 256 when it should be using the SOC provided values. This can result in corruption with linear surfaces where we prefetch more PTE than the buffer can hold.
[How] Update the min page size correctly for the plane.
