Sebastian Andrzej Siewior c0b5195bad ARM: 9426/1: vfp: Move sending signals outside of vfp_state_hold()ed section. ...

VFP_bounce() is invoked from within vfp_support_entry() and may send a
signal. Sending a signal uses spinlock_t which becomes a sleeping lock
on PREEMPT_RT and must not be acquired within a preempt-disabled
section.

Move the vfp_raise_sigfpe() block outside of the vfp_state_hold() section.
