- Make the maxsize parameter of the data buffer DMA tag match maxio, which

Reported and tested by: Michael Moll
- Declare mpt_dma_buf_alloc() static just like mpt_dma_buf_free(), both are

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.
Update some release version numbers. The patch is based on the one
from the PR, but the version numbers reflect the newer ones from

Fix an error in the EXAMPLES section of getopt(1), which is based on

it as it is for now.

Check for overflow before it occurs. Also add check for

- Move i386-inherited logic of building ACPI headers for acpi_wakeup.c into
better places and remove intermediate makefile and shell scripts. This
makes parallel kernel build little bit safer for amd64.
- Make SMP code path in acpi.c conditional at run-time.
- Define SMP unconditionally for amd64 and remove opt_global.h from SRCS in
sys/modules/acpi/acpi/Makefile. Note it is done just for correctness sake
because we do not build, ship, or support acpi.ko on amd64.
- According to ACPICA User Guide and Programmer Reference, the read data
must be zero extended to fill the 32-bit or 64-bit return value even if
the bit width of the port or location is less than 32 or 64.
- 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.
- 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).

CVS r1.94 jhb:
Cast the integer read as the first argument for %b to an unsigned integer
so it's value is not sign extended when assigned to the uintmax_t variable

feature word, then %b would print out the initial value as a 16 character
hexadecimal value. Now it only prints out an 8 character value.

Add support for corrected machine check interrupts. CMCI is a new local

events is reached. CMCI also includes a count of events when reporting
corrected errors in the bank's status register. Note that individual
banks may or may not support CMCI. If they do, each bank includes its own
threshold register that determines when the interrupt fires. Currently
the code uses a very simple strategy where it doubles the threshold on
each interrupt until it succeeds in throttling the interrupt to occur
only once a minute (this interval can be tuned via sysctl). The threshold
is also adjusted on each hourly poll which will lower the threshold once
events stop occurring.
