x86/fpu: Drop fpregs lock before inheriting FPU permissions (2022-11-10 16:57:38 +0100)
----------------------------------------------------------------
- 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
----------------------------------------------------------------

x86/sgx: Add overflow check in sgx_validate_offset_length()
