From: Benjamin Herrenschmidt Date: Tue, 11 Dec 2007 03:48:17 +0000 (+1100) Subject: [POWERPC] Make isa_mem_base common to 32 and 64 bits X-Git-Tag: v2.6.25-rc1~1131^2~311 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=25e81f925d4be0a0f60520e1c3c1b5af744404e1;p=linux-2.6 [POWERPC] Make isa_mem_base common to 32 and 64 bits This defines isa_mem_base on both 32 and 64 bits (it used to be 32 bits only). This avoids a few ifdef's in later patches and potentially can allow support for VGA text mode on 64 bits powerpc.
