| |
This patchset is an attempt to make some implementations of four apic operations bit more sane and readable. It was booted with these apic drivers: flat/flat, flat/phys, bigsmp, x2apic/cluster.
- patches 2,3,4 get rid of duplicate implementation of apic operations - patch 5 tunes the way vectors are assigned - patch 6 makes minor improvement to the code - patches 7,8 are a continuation of 18374d8 commit
