Implement process-shared locks support for libthr.so.3, without

Begin abstracting out the access method for ath(4) ioctls.
Each of the ath* commands do their own direct socket/ioctl calls,

So, this is the beginning of abstracting out the stats API calls

ioctls and use a more general interface.

Fix PIO mode on A31 and later SoCs.
Newer Allwinner MMC implementations use a different FIFO register offset

both cases, base the decision on which FIFO offset to use on the Allwinner
SoC family.

Implement pmap_change_attr() for PowerPC (Book-E only for now)
Summary:
Some drivers need special memory requirements. X86 solves this with a
pmap_change_attr() API, which DRM uses for changing the mapping of the GART and
other memory regions. Implement the same function for PowerPC. AIM currently
does not need this, but will in the future for DRM, so a default is added for
that, for business as usual. Book-E has some drivers coming down that do
require non-default memory coherency. In this case, the Datapath Acceleration
Architecture (DPAA) based ethernet controller has 2 regions for the buffer
portals: cache-inhibited, and cache-enabled. By default, device memory is
cache-inhibited. If the cache-enabled memory regions are mapped
cache-inhibited, an alignment exception is thrown on access.
Test Plan:
Tested with a new driver to be added after this (DPAA dTSEC ethernet driver).
No alignment exceptions thrown, driver works as expected with this.

Move IPI related parts back to (ARM) machine specific file now, when
the interrupt framework is also going to be used by another (MIPS)
architecture. IPI implementations may vary much across different

An IPI implementation should still define INTR_IPI_COUNT and use
intr_ipi_setup_counters() to setup IPI counters which are inside of
intrcnt[] and intrnames[] arrays. Those are used for sysctl and ddb.
Then, intr_ipi_increment_count() should be used to increment obtained
counter.

Although this may not be an issue in practice, it would be more correct if the 64-bit version was used. Also, using the 64-bit version would make it easier to add support for 64-bit ubldr on MIPS.

Bring over the initial rewrite of the broadcom bus support found in their

This is "just" (all 20,000 lines of it) code to enumerate the various
versions of busses inside these devices, including the PCI bridge and
the direct SIBA bridge found in MIPS chips.
It also includes shared code for some bus operations (suspend, resume, etc);
EEPROM/SROM/etc parsing and other things that are shared between chips.
Eventually this'll replace the code that bwi/bwn uses for the internal
bus, as well as some apparently upcoming mips74k broadcom SoC support
which uses bwn!
