This (and eventually migrating the other PHY code out) is in preparation
for adding the 11n PHY. No, the 11ac PHY (for the BCM4260 softmac part) isn't
yet open source, so we can't grow that. Yet.
This trims ~3,700 lines of code from if_bwn.c, bringing it down to a slightly
less crazy sounding 10,446 lines of code.
* Change x/a to work similar to gdb. The content of the memory is
treated as an address, printed symbolically and the address is advanced.
This way you can x/a <stack_address> and then just hit return a bunch
of times to locate useful data on the stack.
* Add x/p. The content of the memory is treated as an address and
printed as hex.
This is based on the similar commit from DragonFlyBSD without the
cosmetic changes.

This patch adds support for restoring backlight after resume and adds models
Macbook3,1
MacbookAir5,1
MacbookAir5,2
It also incorporates fixes for bug #175260, bug #203610 and bug #203512
so those can be closed if this patch is applied.

Implement several small improvements to the suspend/resume Xen sequence:
- Call the power_suspend_early event before stopping all processes.
- Stop all processes. This was done implicitly previously by putting all
the CPUs in a known IPI handler.
- Warm up the timecounter.
- Re-initialize the time of day register.

bus_get_cpus() returns a specified set of CPUs for a device. It accepts
an enum for the second parameter that indicates the type of cpuset to
request. Currently two valus are supported:
- LOCAL_CPUS (on x86 this returns all the CPUs in the package closest to
the device when DEVICE_NUMA is enabled)
- INTR_CPUS (like LOCAL_CPUS but only returns 1 SMT thread for each core)
For systems that do not support NUMA (or if it is not enabled in the kernel
config), LOCAL_CPUS fails with EINVAL. INTR_CPUS is mapped to 'all_cpus'
by default. The idea is that INTR_CPUS should always return a valid set.
Device drivers which want to use per-CPU interrupts should start using
INTR_CPUS instead of simply assigning interrupts to all available CPUs.
In the future we may wish to add tunables to control the policy of
INTR_CPUS (e.g. should it be local-only or global, should it ignore
SMT threads or not).
The x86 nexus driver exposes the internal set of interrupt CPUs from the
the x86 interrupt code via INTR_CPUS.
The ACPI bus driver and PCI bridge drivers use _PXM to return a suitable
LOCAL_CPUS set when _PXM exists and DEVICE_NUMA is enabled. They also and
the global INTR_CPUS set from the nexus driver with the per-domain set from
_PXM to generate a local INTR_CPUS set for child devices.

The current resolution of the Xen PV clock is too high, which causes an
adjustment of 5s to be applied to it. Reduce the resolution to be the same
as the RTC plus one, so it's always selected as the best source when
available on x86.
Also don't reset the clock on resume, it's pointless and discards any
previous adjustments.

Dom0 should be able to set the host time. This is implemented by first
writing to the RTC (as would be done on bare metal), and then using the
XENPF_settime64 hypercall in order to force Xen to update the wallclock
shared page of all domains.

This is going to be used by the Xen clock on Dom0 in order to set the RTC of
the host. The current logic in atrtc_settime is moved to atrtc_set and the
unused device_t parameter is removed from the atrtc_set function call so it
can be safely used by other callers.

With the removal of the usage of the VCPU_SSHOTTMR_future flag, now
all errors from xentimer_vcpu_start_timer should be considered fatal, and
the loop is no longer needed since in case of setting the timer in the past
we will get an event interrupt right away (instead of returning ETIME).

On slow platforms with unreliable TSC, such as QEMU emulated machines,
it is possible for the FreeBSD kernel to request the next event in the
past. In that case, in the current implementation of
xentimer_vcpu_start_timer, we simply return -ETIME. To be precise Xen
returns -ETIME and we pass it on. As a consequence we need to loop
around to function to make sure that the timer is properly set.
Instead it is better to always ask the hypervisor for a timer event,
even if the timeout is past. To do that, remove the VCPU_SSHOTTMR_future
flag.
