Merge tag 'x86_urgent_for_v6.1_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
- Do not hold fpregs lock when inheriting FPU permissions because the
fpregs lock disables preemption on RT but fpu_inherit_perms() does
spin_lock_irq(), which, on RT, uses rtmutexes and they need to be
preemptible.
- Check the page offset and the length of the data supplied by
userspace for overflow when specifying a set of pages to add to an
SGX enclave
