ACPI: fix mis-merge -- invoke acpi_unlazy_tlb() only on C3 entry
This original patch http://ussg.iu.edu/hypermail/linux/kernel/0712.2/1451.html was intending to add acpi_unlazy_tlb() to acpi_idle_enter_bm(), which is used for C3 entry. But it was merged incorrectly as commmit bde6f5f59c2b2b48a7a849c129d5b48838fe77ee 'x86: voluntary leave_mm before entering ACPI C3' so the call was instead added to acpi_idle_enter_simple() (which is C2 entry routine), probably due to identical context in that function. Move the call back to acpi_idle_enter_bm(). Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
