Merge tag 'x86_fpu_for_6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fpu updates from Dave Hansen:
 "There are two little fixes in here, one to give better XSAVE warnings
  and another to address some undefined behavior in offsetof().

  There is also a collection of patches to fix some issues with ptrace
  and the protection keys register (PKRU). PKRU is a real oddity because
  it is exposed in the XSAVE-related ABIs, but it is generally managed
  without using XSAVE in the kernel. This fix thankfully came with a
  selftest to ward off future regressions.

  Summary:

   - Clarify XSAVE consistency warnings

   - Fix up ptrace interface to protection keys register (PKRU)

   - Avoid undefined compiler behavior with TYPE_ALIGN"
