Merge r254263:
Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI
command register. The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR. Thus, the bit is no longer
a reliable indication of capability, and should not be checked. This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.
This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.

Implementation of the HTree directory index.
This is a port of NetBSD's GSoC 2012 Ext3 HTree directory indexing
by Vyacheslav Matyushin. It was cleaned up and enhanced for FreeBSD
by Zheng Liu (lz@).
This is an excellent example of work shared among different projects:
Vyacheslav was able to look at an early prototype from Zheng Liu who
was also able to check the code from Haiku (with permission).
As in linux, the feature is not available by default and must be

- Implement iclear methods for QUICC and SAB 82532. With r253161 in place,
this is is crucial at least for the latter.
What happens is that attaching uart(4) to scc(4) causes the SAB 82532 to
"receive" something and trigger a SER_INT_RXREADY interrupt, given that
at least fast/filter interrupts are already enabled. Prior to r253161,
uart_bus_ihand() was set up at this point and handled that condition,
i. e. read the RX FIFO and issued a Receive Message Complete.
Now, uart_bus_ihand() and uart_intr() are setup after attaching uart(4),
leaving the SER_INT_RXREADY interrupt triggered during the latter to
be handled by the iclear method. However, with that method not implement,
this in turn causes SAB 82532 to not issue any further SER_INT_RXREADY
interrupts until the RX FIFO is full again. Thus, 15 received bytes go
to nowhere, given that "the other half" of the RX FIFO is used for status
information. Hence, implementing sab82532_bfe_iclear() fixes things again.
Potentially, the same problem exists for QUICC.

As it turns out, MSIs are broken with 2820SA so introduce an AAC_FLAGS_NOMSI
quirk and apply it to these controllers [1]. The same problem was reported
for 2230S, in which case it wasn't actually clear whether the culprit is the
controller or the mainboard, though. In order to be on the safe side, flag
MSIs as being broken with the latter type of controller as well. Given that
these are the only reports of MSI-related breakage with aac(4) so far and
OSes like OpenSolaris unconditionally employ MSIs for all adapters of this
family, however, it doesn't seem warranted to generally disable the use of
MSIs in aac(4).
While at it, simplify the MSI allocation logic a bit; there's no need to
check for the presence of the MSI capability on our own as pci_alloc_msi(9)

There is a bug in the ACPICA version 20110527 that is used in stable/9.
The bug can lead to unprotected reference counting on ACPI objects
and eventually to a crash or a memory corruption. The bug has been fixed
upstream and imported to head as of ACPICA version 20130328.
Unfortunately, ACPICA version in stable has not been updated,
so merging all past ACPICA versions or cherry-picking parts of 20130328
would be a big change with a risk of potential regressions.
During debugging it was determined that the most probable vector for the
bug was through concurrent calls to ACPI battery sysctls and ioctls.
The sysctls are already guarded by Giant (not MPSAFE), but ioctls could
execute in parallel to a sysctl call and to each other. All the calls
go through acpi_battery_ioctl function, which makes the actual calls
into ACPICA and those are the calls that lack necessary protection.
Thus preventing concurrency in acpi_battery_ioctl should prevent the
conditions that triggered the ACPICA bug.
Some additional details can be found in this thread:
