Message-ID: <20070623124030.803753497@inhelltoy.tec.linutronix.de> (raw)
In-Reply-To: 20070623124005.931747831@inhelltoy.tec.linutronix.de
[-- Attachment #1: i386-apic-remove-bogus-volatile.patch --]
[-- Type: text/plain, Size: 1184 bytes --]
Remove the volatile in apic. We have a cpu_relax() in the wait loop.
Fix a coding style issue while at it.
