ACPI: don't cond_resched() when irqs_disabled()
The ACPI interpreter usually runs with irqs enabled. However, during suspend/resume it runs with irqs disabled to evaluate _GTS/_BFS, as well as by irqrouter_resume() which evaluates _CRS, _PRS, _SRS. http://bugzilla.kernel.org/show_bug.cgi?id=12252 Signed-off-by: Wu Fengguang <wfg@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
