[ Impact ]
GFX1151 has a problem where the context save / restore area is incorrectly
sized and this can lead to hangs when used with ROCm.

Patches were upstreamed as part of 6.19-rc1 that fix this issue.  They're
already in the OEM 6.14 and OEM 6.17 kernels, but should also be added to
6.17 HWE kernels because some users don't run the OEM kernels.

[ Fix ]
Cherry picks from 6.19-rc1

[ Test Plan ]
Verify that ROCm works properly on GFX1151

[ Where problems could occur ]
GFX1151 specifically, with ROCm
