environment with interrupt enabled. :-)
- Use memcpy(3) instead of copying individual members. I believe struct
x86regs was intentionally copied from the first half of struct x86emu_regs
for this very purpose.

startup and genericize it so it can be reused to map other tables as well:
- Add a routine to walk a list of ACPI subtables such as those used in the
APIC and SRAT tables in the MI acpi(4) driver.
- Move the routines for mapping and unmapping an ACPI table as well as
mapping the RSDT or XSDT and searching for a table with a given signature
out into acpica_machdep.c for both amd64 and i386.

the work area was totally unsynchronized which means this driver only
had a chance of working on x86 when no bounce buffers were involved,
which isn't that likely given that support for 64-bit DMA is currently
broken throughout ata(4).
- Add necessary little-endian conversion of accesses to the work area,
making this driver work on big-endian hosts. While at it, use the
alignment-agnostic byte order encoders in order to be on the safe side.
- Clear the reserved member of the SG list entries in order to be on the
safe side. [1]

30-bit like the reset of the controllers supported by this driver.
Actually ALi M5451 can be setup up to generate 32-bit addresses by
setting the 31st bit via the accompanying ISA bridge, which allows
it to work in sparc64 machines whose IOMMU require at least 32-bit
DMA. Even though other architectures would also benefit from 32-bit
DMA, enabling this bit is limited to sparc64 as bus_dma(9) doesn't
generally guarantee that a low address of BUS_SPACE_MAXADDR_32BIT
results in a buffer in the 32-bit range.
- According to Tatsuo YOKOGAWA's ali(4), the the DMA transfer size of
ALi M5451 is fixed to 64k and in fact using the default size of 4k
- The 4DWAVE DX and NX require the recording buffer to be 8-byte
aligned so adjust the bus_dma_tag_create(9) accordingly.
- Unlike the rest of the controllers supported by this driver, the
ALi M5451 only has 32 hardware channels instead of 64 so limit the
loop in tr_intr() accordingly. [1]

It seems Clang breaks when checking for SPCLKEY, which is now
0x80000000. Using an unsigned integer fixes this. This is also
consistent with other pieces of kbd/syscons code, because these also use
u_int.

- Mark the link as down, so if watchdog reset fails, link watching
failover software can notice it
- Don't send MXGEFW_CMD_ETHERNET_DOWN if the NIC has been reset, it is
not needed, and will fail on a freshly reset NIC.
- Ensure the transmit routines aren't attempting to PIO write to doorbells
while the NIC is being reset.
- Download the correct f/w, rather than using the EEPROM f/w after reset.
- Export a count of the number of watchdog resets via sysctl
- Zero all f/w stats at reset. This will lead to less confusing
diagnostic output when investigating NIC failures.
