From: Ingo Molnar Date: Wed, 28 Jan 2009 04:01:41 +0000 (+0100) Subject: x86: clean up esr_disable() methods X-Git-Tag: v2.6.31-rc1~383^2~508^2~135 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=f6f52baf2613dd319e9ba3f3319bf1f1c442e4b3;p=~shefty%2Frdma-dev.git 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.
