   # HEAD: e5f1e8af9c9e151ecd665f6d2e36fb25fec3b110 x86/fred: Fix system hang during S4 resume with FRED enabled

Miscellaneous x86 fixes:

 - Fix a performance regression on AMD iGPU and dGPU drivers,
   related to the unintended activation of DMA bounce buffers
   that regressed game performance if KASLR disturbed things
   just enough.

 - Fix a copy_user_generic() performance regression on certain
   older non-FSRM/ERMS CPUs

 - Fix a Clang build warning due to a semantic merge conflict
   the Kunit tree generated with the x86 tree

 - Fix FRED related system hang during S4 resume

 - Remove an unused API

 Thanks,

	Ingo
