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
