d4fcf3cba5 Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64.  The optimization is a trivial on recent machines.

8518ed9ecd Simplify the ACPI taskqueue implementation. Use a thread queue type instead
of swi. This allows us to use the taskqueue_thread_* functions instead of
rolling our own. It also avoids a double trip through the queue.

98cc161947 Add the tunable "debug.acpi.max_threads" to allow users to set the
number of task threads to start on boot.  Go back to a default of 3
threads to work around lost battery state problems.  Users that need
a setting of 1 can set this via the tunable.  I am investigating the
underlying issues and this tunable can be removed once they are solved.

67e87637df When the user overrides the DSDT, replace any SSDTs with a simple no-op
table.  acpidump(8) concatenates the body of the DSDT and SSDTs so an
edited ASL will contain all the necessary information.  We can't use a
completely empty table since ACPI-CA reports this as a problem.

2df0b34b24 Don't enter the debugger when executing an AML breakpoint instruction
unless ACPI_DEBUG is defined.  Users don't typically care about errant
breakpoint instructions.  The HP Pavilion 7915 has this in its PCI0
_INI method for rev 0x6040000 of the RSDT.

* Don't attempt to detect if a handler is installed.  Leave that to the

65a7c90189 Add an MI implementation of the ACPI global lock routines and retire the

OS and thus cannot use our mutexes.  It is defined in section 5.2.9.1 of
the ACPI specification.

d3e1c2411e Fix hw.acpi.os_name by renaming it to hw.acpi.osname. The "_name" suffix
is reserved by the loader, and thus any tunable name with that suffix will
be silently discarded.

Document this in the header and man page so that other developers do not
develop so many bumps on the head after banging it against the wall.

ae0781a1cb Revert 1.24. It causes a hang on shutdown for Marcel. This is due to
AcpiEnterSleepState() calling a long AcpiOsStall() with interrupts
disabled.  This fix will instead be added to ACPI-CA.

316ec49abd Some kernel threads try to do significant work, and the default KSTACK_PAGES
doesn't give them enough stack to do much before blowing away the pcb.
This adds MI and MD code to allow the allocation of an alternate kstack
who's size can be speficied when calling kthread_create.  Passing the
value 0 prevents the alternate kstack from being created.  Note that the
ia64 MD code is missing for now, and PowerPC was only partially written
due to the pmap.c being incomplete there.
Though this patch does not modify anything to make use of the alternate
kstack, acpi and usb are good candidates.
