Subject[PATCH] x86/xen: use schedule_timeout_interruptible()
Date
API consolidation with coccinelle found:
./arch/x86/xen/smp.c:499:2-18:
consolidation with schedule_timeout_*() recommended

This is a 1:1 conversion of the current calls to an available helper
only - so only an API consolidation to improve readability.

Patch was compile tested with x86_64_defconfig +
CONFIG_HYPERVISOR_GUEST=y,CONFIG_PARAVIRT=y,CONFIG_XEN=y:

Patch is against 4.1-rc5 (localversion-next is -next-20150529)
