Subject: [PATCH AUTOSEL 6.12 360/486] drm/amdgpu/mes11: fix set_hw_resources_1 calculation

From: Alex Deucher <alexander.deucher@....com>

[ Upstream commit 1350dd3691b5f757a948e5b9895d62c422baeb90 ]

It's GPU page size not CPU page size.  In most cases they
are the same, but not always.  This can lead to overallocation
on systems with larger pages.
