Subject: [this_cpu_xx V2 09/19] Use this_cpu_ptr in crypto subsystem
Date: Wed, 17 Jun 2009 16:33:46 -0400	[thread overview]
Message-ID: <20090617203444.541329806@gentwo.org> (raw)
In-Reply-To: <20090617203337.399182817@gentwo.org>

[-- Attachment #1: this_cpu_ptr_crypto --]
[-- Type: text/plain, Size: 1138 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.
