* Add calls to AcpiSetGpeType. We use wake/run as the type for lid and
button switches since wake-only causes Thinkpads to immediately wake on
the second suspend. Note that with wake/run, some systems return both
wake and device-specific notifies so we don't register for system notifies
for lid and button switches.
* Remove the hw.acpi.osi_method tunable since it is not needed.
* Always print unknown notifies for all types.
* Add more cleanup for the EC if it fails to attach.
* Use the GPE handle now that we parse it. This allows GPEs to be defined
in AML GPE blocks.
* Always use ACPI_NOT_ISR since it's ok to acquire a mutex in our thread
which processes queued requests.
in the various pci specifications as readonly. vendor, subvendor,
device and subdevice are required to be loaded in hardware by some
means that isn't the system BIOS or other system software (although
some devices do have ways of accomplishing this). class and subclass
are defined to be read-only in section 6.2.1 (v2.2). Apart from the
status register, which we weren't touching, these are the only
read-only registers I could find in the 2.2 spec.
progif is also defined as being read-only in section 6.2.1. However,
the PCI IDE programming document specifically states that some of the
bits are read/write. Since we may have to restore registers before we
have a driver attached, go ahead and restore this one byte when
transitioning between D3 and D0.
The PCI spec also says that writes to reserved and unimplemented
registers must be completed normally. It makes no statements about
writes to read-only registers, so be as conservative as possible,
while covering the exception to the rule that is documented in a
subpart of the standard.

polarity rather than assuming that level triggered IRQs use active low and
edge triggered IRQs use active high. Both the MultiProcessor 1.4
and ACPI 2.0 Specifications state in their examples that level triggered
EISA IRQs are active low, but in practice they seem to be active high.

ordinary functions, essentially by backing out half of rev.1.115 of
amd64/exception.S. The handlers must be between certain labels for
the purposes of profiling, and this was broken by scattering them in
separately compiled .S files, especially for ordinary functions that
ended up between the labels. Merge the files by #including them as
before, except with different pathnames and better comments and
organization. Changes to the scattered files are minimal -- just
move the labels to the file that does the #includes.
This also partly fixes profiling of IPIs -- all IPI handlers are now
correctly classified as interrupt handlers, but many are still missing
mcount calls.
The reason for doing this is that (at least some) 4.x binaries are very
unhappy if host.conf does not exist, and if we create host.conf but not
nsswitch.conf, nsswitch.conf will be created at the next reboot, so it
is better to create a correct nsswitch.conf right away.
