09766dd52a Fix a bug in the CPU % limiting code
If you attempt to set a pcpu limit that is higher than
110% using rctl (for instance, you want a jail to be
able to use 2 cores on your system so you set pcpu to
200%) the thing you are trying to limit becomes unthrottled.

b03ca5c3ec FAST_DEPEND: Fix building of wrong source files in some cases.
Similar to the original reason for these dependency hints to be added,
in r124637, the missing-dependency file case can lead to building of the
wrong source.

A clear example of this is in gnu/lib/libstdc++ where the .PATH contains
both contrib/gcc and contrib/libstdc++/src.

  contrib/gcc has a debug.c.
  contrib/libstdc++/src has a debug.cc.

  When building for the objects of debug.o, debug.So, and debug.po, it is
  ambiguous for which src file to use due to the suffix transformation
  rules, even though the proper one is listed first in .PATH.

  This was normally avoided due to these dependency hints for the initial
  build, and then mkdep would add an explicit 'debug.o: debug.cc'
  dependency into the .depend file.  WITH_FAST_DEPEND does not generate
  the .depend file with these, but puts them into .depend.debug.o instead.

Rather than extending the exists() check to each object's .depend.*
file, just enable the hint when when using WITH_FAST_DEPEND.  It fixes
the problem and seems to be safe enough to use since it is mapping SRCS
back to OBJS, rather than letting make make assumptions from OBJS to
SRCS.

A similar check mapping objects to headers is present in some mk files
but was not extended here for FAST_DEPEND since it has not yet been
found to be a problem.

f50e4ebf6a ath(4): begin fleshing out a "reset type" extension to force cold/warn resets.
Right now the only way to force a cold reset is:

* The HAL itself detects it's needed, or
* The sysctl, setting all resets to be cold.

Trouble is, cold resets take quite a bit longer than warm resets.

However, there are situations where a cold reset would be nice.
Specifically, after a stuck beacon, BB/MAC hang, stuck calibration results,
etc.

The vendor HAL has a separate method to set the reset reason (which is
how HAL_RESET_BBPANIC gets set) which informs the HAL during the reset path
why it occured.  This is almost but not quite the same; I may eventually
unify both approaches in the future.

This commit just extends HAL_RESET_TYPE to include both status (eg BBPANIC)
and type (eg do COLD.)  None of the HAL code uses it yet though;  that'll
come later.

It also is a big no-op in each HAL - I need to go teach each of the HALs
about cold/warm reset through this path.

a55a04a892 xen-blkfront: add support for unmapped IO
Using unmapped IO is really beneficial when running inside of a VM,
since it avoids IPIs to other vCPUs in order to invalidate the
mappings.

This patch adds unmapped IO support to blkfront. The following tests
results have been obtained when running on a Xen host without HAP:

PVHVM
     3165.84 real      6354.17 user      4483.32 sys
PVHVM with unmapped IO
     2099.46 real      4624.52 user      2967.38 sys

This is because when running using shadow page tables TLB flushes and
range invalidations are much more expensive, so using unmapped IO
provides a very important performance boost.

5c4133b1b5 x86/dma_bounce: rework _bus_dmamap_load_ma implementation
The implementation of bus_dmamap_load_ma_triv currently calls
_bus_dmamap_load_phys on each page that is part of the passed in buffer.
Since each page is treated as an individual buffer, the resulting behaviour
is different from the behaviour of _bus_dmamap_load_buffer. This breaks
certain drivers, like Xen blkfront.

If an unmapped buffer of size 4096 that starts at offset 13 into the first
page is passed to the current _bus_dmamap_load_ma implementation (so the ma
array contains two pages), the result is that two segments are created, one
with a size of 4083 and the other with size 13 (because two independant
calls to _bus_dmamap_load_phys are performed, one for each physical page).
If the same is done with a mapped buffer and calling _bus_dmamap_load_buffer
the result is that only one segment is created, with a size of 4096.

This patch relegates the usage of bus_dmamap_load_ma_triv in x86 bounce
buffer code to drivers requesting BUS_DMA_KEEP_PG_OFFSET and implements
_bus_dmamap_load_ma so that it's behaviour is the same as the mapped version
(_bus_dmamap_load_buffer). This patch only modifies the x86 bounce buffer
code, other arches are left untouched.
