Subject: [PATCH] CRIS: TLB handling - turn local_save_flags() + local_irq_disable() into local_irq_save()
Date: Fri, 9 Feb 2007 17:39:24 +0100 (CET)	[thread overview]
Message-ID: <Pine.LNX.4.64.0702091735560.22290@jikos.suse.cz> (raw)

Andrew,

some time ago I sent you a bunch of patches that fixed local_irq_save(), 
local_save_flags() and local_irq_disable() all over the tree. You merged 
most of them, but seems to me that two of them went unattended (can't see 
it in your patchset), so I resend.

CRIS: TLB handling - turn local_save_flags() + local_irq_disable() into local_irq_save()

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

Signed-off-by: Jiri Kosina <jkosina@suse.cz>
