Subject: [PATCH] Remove some cruft in apic id checking during processor setup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e4251e130deef9de5226cc36faa70a1c6671d3c5;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.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.
