Subject: [PATCH 031/114] x86: clean up esr_disable() methods
Impact: cleanup
Most subarchitectures want to disable the APIC ESR (Error Status Register),
because they generally have hardware hacks that wrap standard CPUs into
a bigger system and hence the APIC bus is quite non-standard and weirdnesses
(lockups) have been seen with ESR reporting.
Remove the esr_disable macros and put the desired flag into each
subarchitecture's genapic template directly.
