- In sys/ofed/drivers/infiniband/core/cma.c, an enum struct member is
interpreted as an int, so cast it to an int.
- In sys/ofed/drivers/infiniband/core/ud_header.c, initialize the
packet_length variable in ib_ud_header_init(), to prevent undefined
behaviour.
- In sys/ofed/drivers/infiniband/ulp/sdp/sdp_rx.c, call rdma_notify()
with the correct enum type and value.
- In sys/ofed/include/linux/pci.h, change the PCI_DEVICE and PCI_VDEVICE
macros to use C99 struct initializers, so additional members can be
overridden.

When a background copy of a cg is written we complete any work associated
with that bmsafemap. If new work has been added to the non-background
copy of the buffer it will be completed before the next write happens.
The solution is to do the rollbacks when we make the copy so only those
dependencies that were present at the time of writing will be completed
when the background write completes. This would've resulted in various
bitmap related corruptions and panics. It also would've expired journal
entries early causing journal replay to miss some records.

- Check that an argument is always available, otherwise current map
printing before to recurse is garbage.
- Spit out a message if an argument is not provided.
- Remove unread nlines variable.
- Use an explicit recursive function, disassociated from the
DB_SHOW_COMMAND() body, in order to make clear prototype and recursion
of the above mentioned function. The code results now much less
obscure.

This happens during a scan in STA mode; any queued data frames will
be power save queued but as there's no TIM in STA mode, it panics.
This was introduced by me when I disabled my driver-aware power save
handling support.
actual traffic with an AR9380/AR9382/AR9485.
The sample rate control stats would show impossibly large numbers for
"successful packets transmitted." The number was a tad under 2^^64-1.
So after a bit of digging, I found that the sample rate control code
was making 'tries' turn into a negative number.. and this was because
ts_longretry was too small.
The hardware returns "ts_longretry" at the current rate selection,
not overall for that TX descriptor. So if you setup four TX rate
scenarios and the second one works, ts_longretry is only set for
the number of attempts at that second rate scenario. The FreeBSD HAL
code does the correction in ath_hal_proctxdesc() - however, this isn't
possible with EDMA.
EDMA TX completion is done separate from the original TX descriptor.
So the real solution is to split out "find ts_rate and ts_longretry"
from "complete TX descriptor". Until that's done, put a hack in
the EDMA TX path that uses the rate scenario information in the ath_buf.

- Do not try to steal load from other CPUs if there was no contest switches
on this CPU (i.e. it was idle all the time and woke up just for bus mastering
or TLB shutdown). If current CPU was idle, then it is quite unlikely that some
other CPU has load to steal. Under high I/O rate, when TLB shutdowns cause
numerous CPU wakeups, on 24-CPU system load stealing code may consume up to
25% of all CPU time without giving any benefits.
- Change code that implements spinning for load to restart spin in case of
context switch. Previous code periodically called cpu_idle() even under
high interrupt/context switch rate.
- Rise spinning threshold to 10KHz, where it gives at least some effect
that may worth consumed power.

Some hooks are added to clamp down maxusers and nmbclusters for
small address space systems.
VM_MAX_AUTOTUNE_MAXUSERS - the max maxusers that will be autotuned based on
physical memory.
VM_MAX_AUTOTUNE_NMBCLUSTERS - max nmbclusters based on physical memory.
These are set to the old values on i386 to preserve the clamping that was
being done to all arches.
Another macro VM_AUTOTUNE_NMBCLUSTERS is provided to allow an override
for the calculation on a MD basis. Currently no arch defines this.
