Subject: [PATCH] CIRS: turn local_save_flags() + local_irq_disable()into
 local_irq_save()


[ This is just FYI. I have already queued this one in trivial tree. ]

This is a followup to my patches that fixed this all over the tree quite some
time ago. This one went unnoticed for some reason.

TLB handling for CRIS contains local_irq_disable() after local_save_flags().
Turn this into local_irq_save().
