Subject: [my_cpu_ptr 5/5] Use my_cpu_ptr in crypto subsystem
Date: Wed, 27 May 2009 13:47:03 -0400	[thread overview]
Message-ID: <20090527180716.802173094@gentwo.org> (raw)
In-Reply-To: <20090527180635.008102701@gentwo.org>

[-- Attachment #1: my_cpu_ptr_crypto --]
[-- Type: text/plain, Size: 910 bytes --]

Just a slight optimization that removes one array lookup.
The processor number is needed for other things as well so the
get/put_cpu cannot be removed.
