From 05131ecc99ea9da7f45ba3058fe8a2c1d0ceeab8 Mon Sep 17 00:00:00 2001 From: Venkatesh Pallipadi Date: Sun, 23 Oct 2005 16:31:00 -0400 Subject: [ACPI] Avoid BIOS inflicted crashes by evaluating _PDC only once Linux invokes the AML _PDC method (Processor Driver Capabilities) to tell the BIOS what features it can handle. While the ACPI spec says nothing about the OS invoking _PDC multiple times, doing so with changing bits seems to hopelessly confuse the BIOS on multiple platforms up to and including crashing the system. Factor out the _PDC invocation so Linux invokes it only once. http://bugzilla.kernel.org/show_bug.cgi?id=5483 Signed-off-by: Venkatesh Pallipadi Signed-off-by: Len Brown --- arch/i386/kernel/acpi/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/i386/kernel/acpi/Makefile') diff --git a/arch/i386/kernel/acpi/Makefile b/arch/i386/kernel/acpi/Makefile index 267ca48e1b6c..d51c7313cae8 100644 --- a/arch/i386/kernel/acpi/Makefile +++ b/arch/i386/kernel/acpi/Makefile @@ -3,6 +3,6 @@ obj-$(CONFIG_X86_IO_APIC) += earlyquirk.o obj-$(CONFIG_ACPI_SLEEP) += sleep.o wakeup.o ifneq ($(CONFIG_ACPI_PROCESSOR),) -obj-y += cstate.o +obj-y += cstate.o processor.o endif -- cgit v1.2.3
