cpuidle: fix AMD C1E suspend hang

2009-06-15T16:40:07+00:00

commit 7d60e8ab0d5507229dfbdf456501cc378610fa01 upstream.

When AMD C1E is enabled, local APIC timer will stop even in C1. To avoid
suspend/resume hang, this patch removes C1 and replace it with a cpu_relax() in
suspend/resume path. This hasn't any impact in runtime path.

cpuidle: make AMC C1E work in processor_idle

2009-06-15T16:40:07+00:00

commit 87ad57bacb25c3f24c54f142ef445f68277705f0 upstream

broadcast ipi to replace local APIC timer in C1.

ACPI: Revert conflicting workaround for BIOS w/ mangled PRT entries

2009-05-08T22:45:05+00:00

upstream 82babbb3887e234c995626e4121d411ea9070ca5
backported to 2.6.29.2

2f894ef9c8b36a35d80709bedca276d2fc691941
in Linux-2.6.21 worked around BIOS with mangled _PRT entries:
http://bugzilla.kernel.org/show_bug.cgi?id=6859

d0e184abc5983281ef189db2c759d65d56eb1b80
worked around the same issue via ACPICA, and shipped in 2.6.27.

Unfortunately the two workarounds conflict:

So revert the Linux specific one.

dock: fix dereference after kfree()

2009-04-27T17:36:52+00:00

upstream commit: f240729832dff3785104d950dad2d3ced4387f6d

dock_remove() calls kfree() on dock_station so we should use
list_for_each_entry_safe() to avoid dereferencing freed memory.

Found by smatch (http://repo.or.cz/w/smatch.git/).  Compile tested.

acpi: check for pxm_to_node_map overflow

2009-03-16T04:35:30+00:00

It is hardly (if ever) possible but in case of broken _PXM entry we could
reach out of pxm_to_node_map array bounds in acpi_map_pxm_to_node() call.

ACPI: remove doubled status checking

2009-03-16T04:35:30+00:00

There was a misplaced status test (two consequent tests without a
statement in between) in acpi_bus_init for ages.  Remove it, since the
function which should be checked (acpi_os_initialize1) has BUG_ONs on
failure paths.

Revert "ACPI: make some IO ports off-limits to AML"

2009-03-16T04:35:29+00:00

This reverts commit 5ec5d38a1c8af255ffc481c81eef13e9155524b3.
because it caused spurious dmesg warmings.
We'll implement the check for off-limit ports
in a more clever way in the future.

suspend: switch the Asus Pundit P1-AH2 to old ACPI sleep ordering

2009-03-16T04:35:28+00:00

Switch the Asus Pundit P1-AH2 (M2N8L motherboard) to the old ACPI 1.0
sleep ordering by default.  Without this it will not suspend/resume
correctly.
