Revision b032bf70df2e43149ce2b4e9a865b076c6140753 authored by Thomas Gleixner on 27 July 2008, 21:47:12 UTC, committed by Linus Torvalds on 28 July 2008, 15:31:58 UTC
pm_idle_save resp. pm_idle_old can be NULL when the restore code in acpi_processor_cst_has_changed() resp. cpuidle_uninstall_idle_handler() is called. This can set pm_idle unconditinally to NULL, which causes the kernel to panic when calling pm_idle in the x86 idle code. This was covered by an extra check for !pm_idle in the x86 idle code, which was removed during the x86 idle code refactoring. Instead of restoring the pm_idle check in the x86 code prevent the acpi/cpuidle code to set pm_idle to NULL.
