Subject: x86, VisWS: turn into generic arch, enhance include/asm-x86/mach-default/smpboot_hooks.h
X-Git-Tag: v2.6.27-rc1~1106^2~14^2~24
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6a64b5da9bbe561fd189361812f5ed205bb55345;p=linux-2.6

x86, VisWS: turn into generic arch, enhance include/asm-x86/mach-default/smpboot_hooks.h

Allow the generic smpboot quirks code to be built with
ONFIG_X86_IO_APIC disabled. This way VISWS will be able
to use it as-is.
