(obvious in retrospect) in which interrupts on one CPU that are temporarily
masked can end up permanently masked when a handler on another CPU clobbers
the interrupt mask register with an old copy.
rather than global variables.
This specifically allows for debugging to be enabled per-NIC, rather
than globally.
Since the ath driver doesn't know about AH_DEBUG, and to keep the ABI
consistent regardless of whether AH_DEBUG is enabled or not, enable the
debug parameter always but only conditionally compile in the debug
methods if needed.
The ALQ support is currently still global pending some brainstorming.

This was previously done only for SCSI XPT in r223081, on which the change
in r223089 depended in order to respond to serial number requests. As a
result of r223089, da(4) and ada(4) devices register a d_getattr for geom to
use to obtain the information.

Add inbound handler to the alias_ftp module. It helps handle active

NAT. Fix passive FTP transfer case for server behind NAT using redirect with

processors unless the invariant TSC bit of CPUID is set. Intel processors
may stop incrementing TSC when DPSLP# pin is asserted, according to Intel
processor manuals, i. e., TSC timecounter is useless if the processor can
enter deep sleep state (C3/C4). This problem was accidentally uncovered by
r222869, which increased timecounter quality of P-state invariant TSC, e.g.,
for Core2 Duo T5870 (Family 6, Model f) and Atom N270 (Family 6, Model 1c).

resource allocation from an x86 Host-PCI bridge driver so that it can be
reused by the ACPI Host-PCI bridge driver (and eventually the MPTable
Host-PCI bridge driver) instead of duplicating the same logic. Note that
this means that hw.acpi.host_mem_start is now replaced with the
hw.pci.host_mem_start tunable that was already used in the non-ACPI case.
This also removes hw.acpi.host_mem_start on ia64 where it was not
applicable (the implementation was very x86-specific).
While here, adjust the logic to apply the new start address on any
"wildcard" allocation even if that allocation comes from a subset of
the allowable address range.

register both status change and link state change callbacks.
Implement checking valid link in state change callback and poll
active link state in vr_tick(). This allows immediate detection of
lost link as well as protecting driver from frequent link flips during
link renegotiation. taskq implementation was removed because driver
now needs to poll link state in vr_tick().
While I'm here do not report current link state if interface is not
running.

o Consider No CIS a normal event and stop whining about it so much
(too many cards are like this, espeically usb/firewire cards).
o Add comments to the cis reading code.
o Made the read from config space a smidge easier to read and eliminate

uid<->username mapping cache with an entry when another entry
for that uid is already loaded. This fixes a case where the
mapping of "toor" would replace "root" when the daemon was started,
resulting in no mapping for "root" until the cache entry for "toor"
timed out.
The algorithm is inefficient, but since it is only done once when
the daemon is started up, I don't think that's an issue.

don't affect the normal case (since this case needn't be optimized and
this guards against all races).
