pause_sbt(). This allows pause() to continue working during a panic()
which is not invoking KDB. This is useful when debugging graphics
drivers using the LinuxKPI.

It does not belong to the vmbus.
While I'm here rework the Hypercall setup, e.g. use busdma(9)
and avoid bit fields.

The variable "size" stores number of words (4bytes). But the loop over
memory uses size as number of bytes to scan memory. As result it fetches
only 1/4th of memory.
This patch solves this problem and nvram2env fetches all NVRAM variables.
Test plan:
Pre-requisites: any MIPS board with ASCII-based NVRAM mapped into memory
* Add "device nvram2env" into kernel configuration
* Specify hints: base is mandatory (according to nvram2env(4))
hint.nvram.0.base=0x1c7f8000 (it's valid address for Asus RT-N53 with
flags = 0x4)
* Build & load kernel with bootverbose
Actual result: only part of nvram variables are found
Expected result: all variables are found

This adds a BHND_BUS_GET_ATTACH_TYPE(); the primary use-case is to let
chipc make a coarse-grained determination as to whether UART, SPI, etc
drivers ought to be attached, and on fullmac devices, whether a real
CPU driver ought to be skipped for the ARM core, etc.
Tested:
* BCM4331 (BHND)
* BCM4312 (SIBA)

This diff updates DEFINE_CLASS_2/_3 to support the specification of class
name separately from the class variable name, bringing them into sync
with their API documentation, as well as the behavior of DEFINE_CLASS_0/_1.
Nothing in the tree currently uses the _2/_3 variants, and I can't
find any references to the API outside of commits to the kobj.h
header itself; given the limitation that currently exists, I'd
be surprised if they've ever been used.

Replace the magic constant 127 in the loop interation count with
"PROMPTLEN - 1".
gethostname() is not guaranteed to NUL terminate the destination
string if it is too short. Decrease the length passed to gethostname()
by one, and add a NUL at the end of the buffer to make sure the
following loop to find the end of the name properly terminates.
The default: case is the likely cause of Coverity CID 1008328. If
i is 126 at the top of the loop interation where the default case
is triggered, i will be incremented to 127 by the default case,
then incremented to 128 at the top of the loop before being compared
to 127 (PROMPTLENT - 1) and terminating the loop. Then the NUL
termination code after the loop will write to ps[128]. Fix by
checking for overflow before incrementing the index and storing the
second character in the buffer.
These fixes are not guaranteed to satisfy Coverity. The code that
increments i in the 'h'/'H' and 'w'/'W' cases may be beyond its
capability to analyze, but the code appears to be safe.

It turns out we need to leave this in place for a while so that people
running self-hosting armv6hf systems can do the builds necessary to update
to armv6 (which is now hardfloat by default).
In this configuration, a separate bootpool is not required.
This allows ZFS Boot Environments to be used with GELI encrypted ZFS pools.
Support for GPT+EFI+GELI is planned for the future.

Override global retry limit (which is set in R92C_RL) via per-frame
TX descriptor field. Obsoletes D3840 (should work better with 2+ vaps).
Tested with RTL8188EU and RTL8192CUS in STA mode (maxretry = [3-9]).
As a positive side-effect, this eliminates the double semicolons reported by Coverity:
the macro contained a trailing semicolon, in addition to the semicolon placed on
each line where EXPAND(..) was called.

The root file system is mounted early via vfs.root.mountfrom.
The canmount=noauto property only affects the zfs rc.d script.
This ensures that the 'default' BE is not mounted overtop of another BE when
one is selected from the beastie menu

- Revert the change for seed(0) in r300384. I misunderstood the standard
and while our random() implementation in libkern may be improved, it
handles the seed(0) case fine.

After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C
reference and as result, the temperature read in sysctl(8) now exibits a
+0.1C difference.
This commit fix the kernel references to match the reference value used in
sysctl(8) after r285994.
