b3f35be0c6 - Prefer ACPI_COMPARE_NAME(a, b) macro over strncmp(a, b, ACPI_NAME_SIZE).
- Make sure the predefined name is a string type.
- Return slightly more useful errors.

731634f7fe De-obfuscate acpi_acquire_global_lock(). It seems the function was directly
translated from i386 assembly version.

82bf55575d Allow AcpiOsInstallInterruptHandler() and AcpiOsRemoveInterruptHandler() to
install or remove non-SCI interrupt handlers per ACPI Component Architecture
User Guide and Programmer Reference.  ACPICA may install such interrupt
handler when a GPE block device is found, for example.  Add a wrapper for
ACPI_OSD_HANDLER, convert its return values to ours, and make it a filter.
Prefer KASSERT(9) over panic(9) as we have never seen those in reality.
Clean up some style(9) nits and add my copyright.

69496408a5 Simplify AcpiOsReadPort() and AcpiOsWritePort() with iodev_read_*() and
iodev_write_*().  This removes unnecessary uses of temporary macros as well.
There is no functional change after this (verified with md5(1) on amd64).

aa353b1b6b Use pmap_mapdev()/pmap_unmapdev() to map device memory instead of using
AcpiOsMapMemory()/AcpiOsUnmapMemory() (-> pmap_mapbios()/pmap_unmapbios())
for AcpiOsReadMemory() and AcpiOsWriteMemory().  Although they do not sound
too obvious, these functions are exclusively used to access memory mapped
IO in ACPICA.

6e7661023a - AcpiOsReadPciConfiguration() needs similar fixes as r209965 and r210129.
According to ACPICA User Guide and Programmer Reference, the read data must
be zero extended to fill the 64-bit return value even if the bit width of
the location is less than 64.
- Return error when 64-bit access is requested as we do not support 64-bit
PCI register access (yet).  XXX We may have to split it up into two 32-bit
accesses if it is really required.

89339b38d8 - AcpiOsReadMemory() needs similar fixes as r209965. [1]
According to ACPICA User Guide and Programmer Reference, the read data must
be zero extended to fill the 32-bit return value even if the bit width of
the port is less than 32.
- Remove 64-bit read/write from AcpiOsReadMemory() and AcpiOsWriteMemory().
These functions do not support 64-bit access (yet).  Clean up style nits
and unnecessary bit masking while I am here.

3ff9febde6 Catch up with r193750 (OsdSynch.c locking changes):
- Preallocate some memory for ACPI tasks early enough.  We cannot use
malloc(9) any more because spin mutex may be held here.  The reserved
memory can be tuned via debug.acpi.max_tasks tunable or ACPI_MAX_TASKS
in kernel configuration.  The default is 32 tasks.
- Implement a custom taskqueue_fast to wrap the new memory allocation.
This implementation is not the fastest in the world but we are being
conservative here.

- Implement ACPI mutex (ACPI_MUTEX) with mutex(9).
- Implement ACPI lock (ACPI_SPINLOCK) with spin mutex(9).

57675eb3fa As soon as we have several threads per process now, it is not correct to
use process ID as ACPI thread ID. Concurrent requests with equal thread
IDs broke ACPI mutexes operation causing unpredictable errors including
AE_AML_MUTEX_NOT_ACQUIRED that I have seen.

Use kernel thread ID instead of process ID for ACPI thread.

4c12fb6750 Fix GPE livelock that occurs on HP/Compaq laptops, mostly in the thermal
zone code.  The GPE handler method (i.e. _L00) generates various Notify
events that need to be run to completion before the GPE is re-enabled.
In ACPI-CA, we queue an asynch callback at the same priority as a Notify
so that it will only run after all Notify handlers have completed.  The
callback re-enables the GPE afterwards.  We also changed the priority of
Notifies to be the same as GPEs, given the possibility that another GPE
could arrive before the Notifies have completed and we don't want it to
get queued ahead of the rest.

The ACPI-CA change was submitted by Alexey Starikovskiy (SUSE) and will
appear in a later release.  Special thanks to him for helping track this
bug down.

3de213cc00 Add a new 'why' argument to kdb_enter(), and a set of constants to use
for that argument.  This will allow DDB to detect the broad category of
reason why the debugger has been entered, which it can use for the
purposes of deciding which DDB script to run.

Assign approximate why values to all current consumers of the
kdb_enter() interface.

e49e68cc9d Use a unique name for each mutex now that acpi-ca is creating more than
one (hardware & global lock).  This should address witness complaints that
a duplicate mutex is being acquired.  Be sure to free the mutex to fix a
potential memory leak.
