Untangle some of the confusion about what role means when it's in the FCPARAM/SDPARAM
or isp_fc/isp_spi structures. This fixed a problem about seeing targets appear if you've
turned off autologin and find them, or rather don't, via camcontrol rescan.

configuration space on Yukon Ultra(88E8056) such that accesses to
these registers were NOPs which in turn make msk(4) instable on
this controller. Use indirect access method to access
PCI_OUR_REG_[1-5] registers. This should fix a long standing
instability bug which prevented msk(4) working on Yukon Ultra.
Special thanks to koitsu who gave me remote access to his system.

arcconf tool by Adaptec already seems to use for identifying the
Serial Number of the devices.
Some simple things (like FIB setup and bound checks) are retrieved
from the Adaptec's driver, but this implementation is quite different
because it does use the normal buffer dmat area for loading segments
and not a special one (like the Adaptec's one does).

have the delayed function take an argument as to the offset
to the SCTP header. This allows it to work for V4 and V6.
This of course means changing all callers of the function
to either pass the header len, if they have it, or create
it (ip_hl << 2 or sizeof(ip6_hdr)).

Yukon FE and Yukon Ultra2. These controllers provide very simple
checksum computation mechanism and it requires additional pseudo
header checksum computation in upper stack. Even though I couldn't
see much performance difference with/without Rx checksum offloading
it may help notebook based controllers.
Actually controller can compute two checksum value by giving
different starting position of checksum computation on received
frame. However, for long time, Marvell's checksum offloading engine
have been known to have several silicon bugs so don't blindly trust
computed partial checksum value. Instead, compute partial checksum
twice by giving the same checksum computation position and compare
the result. If the value is different it's clear indication of
hardware bug. This configuration lose IP checksum offloading
capability but I think it's better to take safe route.
Note, Rx checksum offloading for Yukon XL was still disabled due to
known silicon bug.

acknowledging an interrupt may yield another status block update.

- extend the vendor specific request function by one length pointer argument,
because not all descriptors store the length in the first byte. For example
HID descriptors.

Also disable relaxed ordering as recommended by data sheet for
PCI-X devices. For PCI-X BCM5704, set maximum outstanding split
transactions to 0 as indicated by data sheet.
For BCM5703 in PCI-X mode, DMA read watermark should be less than
or equal to maximum read byte count configuration. Enforce this
limitation in DMA read watermark configuration.
chip revision often found in the blades and resulting in interfaces
not sensing carrier signal. Looking at all problem reports it
appears that it only affects some very specific silicon revision
(ASIC (0x57081021); Rev (B2)) and version of the PHY that
supports 1000baseSX-FDX media only. Therefore, narrow the scope of
workaround to combination of that revision and media type. Given
that the first report on this issue is dated back to 2007, there is
not much hope that this issue will ever be properly resolved.
Among affected systems are IBM HS21, Intel SBXD132 and HP BL460c.

Setting the new sysctl MIB "debug.acpi.enable_debug_objects" to a non-zero
value enables us to print Debug object when something is written to it.
- Allow users to disable interpreter slack mode. Setting the new tunable
"debug.acpi.interpreter_slack" to zero disables some workarounds for common
BIOS mistakes and enables strict ACPI implementations by the specification.
pmc_flush_logfile is now non-blocking and just ask the kernel
to shutdown the file. From that point, no more data is
accepted by the log thread and when the last buffer is flushed
the file is closed.
This will remove a deadlock between pmcstat asking for
flush while it cannot flush the pipe itself.
