(There's a lot more in the pipe):
- Prevent corruption of the XSTATE buffer in signal handling by
validating what is being copied from userspace first.
- Invalidate other task's preserved FPU registers on XRSTOR failure
(#PF) because latter can still modify some of them.
- Restore the proper PKRU value in case userspace modified it
- Reset FPU state when signal restoring fails
Other:
- Map EFI boot services data memory as encrypted in a SEV guest so that
the guest can access it and actually boot properly
- Two SGX correctness fixes: proper resources freeing and a NUMA fix

"A first set of urgent fixes to the FPU/XSTATE handling mess^W code.

* tag 'x86_urgent_for_v5.13_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/mm: Avoid truncating memblocks for SGX memory
x86/sgx: Add missing xa_destroy() when virtual EPC is destroyed
x86/fpu: Reset state for all signal restore failures
x86/pkru: Write hardware init value to PKRU when xstate is init
x86/process: Check PF_KTHREAD and not current->mm for kernel threads
x86/fpu: Invalidate FPU state after a failed XRSTOR from a user buffer
x86/fpu: Prevent state corruption in __fpu__restore_sig()
x86/ioremap: Map EFI-reserved memory as encrypted for SEV
