From 996520c1fdd2948addb629be56c9febf2967e02b Mon Sep 17 00:00:00 2001 From: Venki Pallipadi Date: Mon, 24 Mar 2008 14:24:10 -0700 Subject: [PATCH] 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().
