-Subject: [PATCH 4/5] drm/amd/display: Move the memory allocation out of
- dcn21_validate_bandwidth_fp().
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
-
-dcn21_validate_bandwidth_fp() is invoked while FPU access has been
-enabled. FPU access requires disabling preemption even on PREEMPT_RT.
-It is not possible to allocate memory with disabled preemption even with
-GFP_ATOMIC on PREEMPT_RT.
-
-Move the memory allocation before FPU access is enabled.
