Subject: [PATCH] Remove some cruft in apic id checking during processor setup
X-Git-Tag: v2.6.19-rc1~1077^2~67
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e4251e130deef9de5226cc36faa70a1c6671d3c5;p=linux-2.6-omap-h63xx.git

[PATCH] Remove some cruft in apic id checking during processor setup

- Remove a define that was used only once
- Remove the too large APIC ID check because we always support
the full 8bit range of APICs.
- Restructure code a bit to be simpler.
