* x86: msr: propagate errors from smp_call_function_single()H. Peter Anvin2008-08-251-10/+12
| | | | | | | | Propagate error (-ENXIO) from smp_call_function_single(). These errors can happen when a CPU is unplugged while the MSR driver is open. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* smp_call_function: get rid of the unused nonatomic/retry argumentJens Axboe2008-06-261-4/+4
| | | | | | | | It's never used and the comments refer to nonatomic and retry interchangably. So get rid of it. Acked-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* i386: simplify smp_call_function_single() call sequence in msr-on-cpuAvi Kivity2007-10-171-40/+22
