From: Ingo Molnar Date: Wed, 28 Jan 2009 11:43:18 +0000 (+0100) Subject: x86: refactor ->setup_portio_remap() subarch methods X-Git-Tag: firefly_0821_release~13973^2~508^2~120 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d83093b50416f4ca59d3a84b2ddc217748214d64;p=firefly-linux-kernel-4.4.55.git x86: refactor ->setup_portio_remap() subarch methods Only NUMAQ has a real ->setup_portio_remap() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers. Also move the NUMAQ method from the header file into the apic driver .c file.
