A previous change moved the GETATTR RPC for open() calls that hit in the
name cache up into nfs_lookup() instead of nfs_open(). Continue this
trend by flushing the attribute cache for leaf nodes in nfs_lookup() during
an open() if we do a LOOKUP RPC. For NFSv3 this should generally be a NOP
as the attributes are flushed before fetching the post-op attributes from
the LOOKUP RPC which most (all?) NFSv3 servers provide, so the post-op
attributes should populate the cache.
Now all NFS open() calls will always clear the cached attributes during the
nfs_lookup() prior to nfs_open() in the !NMODIFIED case to provide CTOC.
As a result, we can remove the conditional flushing of the attribute
cache from nfs_open().

Change the mpt driver to allow larger I/O sizes.
The mpt driver previously didn't report a 'maxio' size to CAM, and so the
da(4) driver limited I/O sizes to DFLTPHYS (64K) by default. The number
of scatter gather segments allowed, as reported to busdma, was
(128K / PAGE_SIZE) + 1, or 33 on architectures with 4K pages.
Change things around so that we wait until we've determined how many
segments the adapter can support before creating the busdma tag used for
buffers, so we can potentially support more S/G segments and therefore
larger I/O sizes.
Also, fix some things that were broken about the module unload path. It
still gets hung up inside CAM, though.
mpt.c: Move some busdma initialization calls in here, and call
them just after we've gotten the IOCFacts, and know how
many S/G segments this adapter can support.
mpt.h: Get rid of MPT_MAXPHYS, it is no longer used.
Add max_cam_seg_cnt, which is used to report our maximum
I/O size up to CAM.
mpt_cam.c: Use max_cam_seg_cnt to report our maximum I/O size to CAM.
Fix the locking in mpt_cam_detach().
mpt_pci.c: Pull some busdma initialization and teardown out and put
it in mpt.c. We now delay it until we know many scatter
gather segments the adapter can support, and therefore
how to setup our busdma tags.
mpt_raid.c: Make sure we wake up the right wait channel to get the
raid thread to wake up when we're trying to shut it down.

the bit width of the port or location is less than 32 or 64.

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.
- Remove 64-bit access from AcpiOsReadMemory() and AcpiOsWriteMemory().
These functions do not support 64-bit access. Likewise, return error when
64-bit access is requested for PCI configuration space.
- 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).
