new, simplified, ELF ABI that avoids some of the stranger aspects of the
existing 64-bit PowerPC ABI (function descriptors, in particular). Actually
generating such executables requires a new version of binutils and a newer
compiler (either GCC or clang) than GCC 4.2.1.
The dumpdev kenv supports devices without the /dev/ prefix, fix dumpon to
also support this which is required after r288153.

Hacks to enable target mode there complicated code, while didn't really
work. And for outdated hardware fixing it is not really interesting.
Initiator mode tested with Qlogic 1080 adapter is still working fine.
- Use a temporary file for convert.c to reduce likelihood of an interrupted
build resulting in bad code being written to convert.c
- Truncate the file instead of appending to it to ensure that the file being
touched will not result in duplicate declarations/definitions from
kern_acct.c if/when kern_acct.c changes.

sysentvec. This allows the timekeep data to be shared between similar
ABIs which cannot share sysentvec.
Make the timekeep_push_vdso() tick callback to the timekeep structures
instead of sysentvecs. If several sysentvec share the vdso_sv_tk
structure, we would update the userspace data several times on each
tick, without the change.
Only allocate vdso_sv_tk in the exec_sysvec_init() sysinit when
sysentvec is marked with the new SV_TIMEKEEP flag. This saves
allocation and update of unneeded vdso_sv_tk for ABIs which do not
provide userspace gettimeofday yet, which are PowerPCs arches right
now.
Make vdso_sv_tk allocator public, namely split out and export
alloc_sv_tk() and alloc_sv_tk_compat32(). ABIs which share timekeep
data now can allocate it manually and share as appropriate.

No behavioral changes, just cosmetics.
A partition number of zero is not a wildcard, it's the 'a' partition in
a BSD slice, so don't print it as "<auto>". (Only slices are 1-based,
unit and partition numbers are 0-based and -1 is their wildcard marker.)
Also, after doing all the probing and choosing, print the final result as
"Booting from <disk spec>" where disk spec has all the wildcards resolved
and looks like familiar BSD slice-and-partition notation (disk0s3a, etc).
While later firmware always registers for RSCN requests, older one does
it only in initiator mode. But in target mode there RSCN can be the only
way to detect gone intiator.
The r289895 revision did not accounted for the block containing the
requested page, when calculating the run of pages. Include the pages
before/after the requested page, that fit into the reqblock, into the
calculation.

Summary:
* Take advantage of NEW_PCIB to remove a lot of setup code.
* Fix some bugs related to multiple PCI bridges.
There's still room for more cleanup, and still some bugs leftover, but this
cleans up a lot.
Test Plan: Tested on P5020 board with IDT PCIe switch.

(opens, locks, etc) is retained, which I believe is correct behaviour.
However, for NFSv4.1, the server also retained a reference to the xprt
(RPC transport socket structure) for the backchannel. This caused
svcpool_destroy() to not call SVC_DESTROY() for the xprt and allowed
a socket upcall to occur after the mutexes in the svcpool were destroyed,
causing a crash.
This patch fixes the code so that the backchannel xprt structure is
dereferenced just before svcpool_destroy() is called, so the code
does do an SVC_DESTROY() on the xprt, which shuts down the socket upcall.

of the SRS (software reset) bit in the watchdog control register. Despite
what the manual seems to imply, this bit DOES trigger an immediate reset, as
opposed to simply flagging the type of reset as software-triggered.
For those chips we are not receiving login events, adding initiators
based on ATIO requests. But there is no port ID in that structure, so
in fabric mode we have to explicitly fetch it from firmware to be able
to do normal scan after that.
created for bus_dma_tag_t tag, bounce pages should be allocated
only if needed.
Before the fix, they were allocated always if BUS_DMA_COULD_BOUNCE flag
was set but BUS_DMA_MIN_ALLOC_COMP not. As bounce pages are never freed,
it could cause memory exhaustion when a lot of such tags together with
their maps were created.
Note that there could be more maps in one tag by current design.
However BUS_DMA_MIN_ALLOC_COMP flag is tag's flag. It's set after
bounce pages are allocated. Thus, they are allocated only for first
tag's map which needs them.

is so unusual. Turn off mis-match warnings for building uathload
because the firmware .o file is produced in a way that we
can't get to match exactly. This fixes the build on mips,
so stop excluding it from the build.
