Merge tag 'x86-urgent-2025-04-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fixes from Ingo Molnar:

 - 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
