Subject: [PATCH v3 7/8] x86/acpi: Use __pa_symbol instead of __pa on C visible symbols
Date: Mon, 05 Nov 2012 11:06:08 -0800	[thread overview]
Message-ID: <20121105190605.10205.76277.stgit@gitlad.jf.intel.com> (raw)
In-Reply-To: <20121105185657.10205.27419.stgit@gitlad.jf.intel.com>

This change just updates one spot where __pa was being used when __pa_symbol
should have been used.  By using __pa_symbol we are able to drop a few extra
lines of code as we don't have to test to see if the virtual pointer is a
part of the kernel text or just standard virtual memory.
