From: Russell King Date: Sat, 12 May 2007 14:25:50 +0000 (+0100) Subject: [ARM] Use new get_irqnr_preamble X-Git-Tag: v2.6.22-rc1~1^2~1 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=641e79129a56a4c50be1aed0fa713f440b46a440;p=linux-2.6 [ARM] Use new get_irqnr_preamble Use the new get_irqnr_preamble macro to move the address of the IRQ controller outside the IRQ handling loop.
