Merge ACPICA 20120215.

Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.

This means that their use is restricted to a single C file.

Merge ACPICA 20100806.

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.

- 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.

Import ACPICA 20090521.

Catch up with ACPI-CA 20070320 import.

First pass at allowing memory to be mapped using cache modes other than
WB (write-back) on x86 via control bits in PTEs and PDEs (including making
use of the PAT MSR). Changes include:
- A new pmap_mapdev_attr() function for amd64 and i386 which takes an
additional parameter (relative to pmap_mapdev()) specifying the cache
mode for this mapping. Note that on amd64 only WB mappings are done with
the direct map, all other modes result in a private mapping.
- pmap_mapdev() on i386 and amd64 now defaults to using UC (uncached)
mappings rather than WB. Previously we relied on the BIOS setting up
MTRR's to enforce memio regions being treated as UC. This might make
hw.cbb_start_memory unnecessary in some cases now for example.
- A new pmap_mapbios()/pmap_unmapbios() API has been added to allow places
that used pmap_mapdev() to map non-device memory (such as ACPI tables)
to do so using WB as before.
- A new pmap_change_attr() function for amd64 and i386 that changes the
caching mode for a range of KVA.
