Subject: [PATCH 02/18] powerpc/crypto: Remove users of virt_to_abs() and phys_to_abs() in nx crypto driver
Date: Thu, 26 Jul 2012 17:19:48 +1000	[thread overview]
Message-ID: <1343287204-7700-2-git-send-email-michael@ellerman.id.au> (raw)
In-Reply-To: <1343287204-7700-1-git-send-email-michael@ellerman.id.au>

phys_to_abs() is a nop, don't use it.

virt_to_abs() is just a wrapper around __pa(), call __pa() directly.
