Arnaud Patard 872d83d00f ACPI: suppress power button event on S3 resume
http://bugzilla.kernel.org/show_bug.cgi?id=6612

Note that this fix depends on a fix in ACPICA 20060608
to replace a semaphore with a spin-lock.

Bjorn Helgaas e6f1f3c549 ACPI: Don't print internal BIOS names of wakeup devices
Internal BIOS names like these should be exposed
to the user as little as possible:

ACPI wakeup devices: C069 C0CE C1D1 C0DE C1D4

Eventually, the "wakeup" property of a device should be exported via the
device tree, not by a printk of an internal BIOS name.  For the hard-core,
these are still available in /proc/acpi/wakeup_devices, just not
printed to dmesg.

Shaohua Li eb9289eb20 [PATCH] introduce .valid callback for pm_ops
Add pm_ops.valid callback, so only the available pm states show in
/sys/power/state.  And this also makes an earlier states error report at
enter_state before we do actual suspend/resume.

Pavel Machek b01d8684e9 [PATCH] remove ACPI S4bios support
Remove S4BIOS support.  It is pretty useless, and only ever worked for _me_
once.  (I do not think anyone else ever tried it).  It was in feature-removal
for a long time, and it should have been removed before.

Eric W. Biederman 8dbddf1782 [PATCH] acpi_shutdown: Only prepare for power off on power_off
When acpi_sleep_prepare was moved into a shutdown method we
started calling it for all shutdowns.

It appears this triggers some systems to power off on reboot.

Avoid this by only calling acpi_sleep_prepare if we are going to power
off the system.

Eric W. Biederman b35c67a46b [PATCH] acpi: Don't call acpi_sleep_prepare from acpi_power_off
Now that all of the code paths that call acpi_power_off
have been modified to call either call kernel_power_off
(which calls apci_sleep_prepare by way of acpi_shutdown)
or to call acpi_sleep_prepare directly it is redundant to call
acpi_sleep_prepare from acpi_power_off.

So simplify the code and simply don't call acpi_sleep_prepare.

In addition there is a little error handling done so if we
can't register the acpi class we don't hook pm_power_off.

I think I have done the right thing with the CONFIG_PM define
but I'm not certain.  Can this code even be compiled if
CONFIG_PM is false?

Eric W. Biederman 6660316cb7 [PATCH] acpi_power_off: Don't switch to the boot cpu
machine_power_off on i386 and x86_64 now switch to the
boot cpu out of paranoia and because the MP Specification indicates it
is a good idea on reboot, so for those architectures it is a noop.
I can't see anything in the acpi spec that requires you to be on
the boot cpu to power off the system, so this should not be an issue
for ia64.  In addition ia64 has the altix a massive multi-node
system where switching to the boot cpu sounds insane as we may
hot removed the boot cpu.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
