From the PR description:
The gcc runtime's _Unwind_Find_FDE function, invoked during exception
handling's stack unwinding, is not safe to execute from within multiple
threads. FreeBSD' s dl_iterate_phdr() however permits multiple threads
to pass through it though. The result is surprisingly reliable infinite
looping of one or more threads if they just happen to be unwinding at
the same time.
Introduce the new lock that is write locked around the dl_iterate_pdr,
thus providing required exclusion for the stack unwinders.

code to collect argument data if auditing is enabled but the current

- If the last of the child cpufreq drivers returns an error while trying to
fetch its list of supported frequencies but an earlier driver found the
requested frequency, don't return an error to the caller.
- If all of the child cpufreq drivers fail and the attempt to match the
frequency based on 'cpu_est_clockrate()' fails, return ENXIO rather than
returning success and returning a frequency of CPUFREQ_VAL_UNKNOWN.

In addition to the intr forcing added with rev. 1.205 adopt the other
places to use the same logic.
We need to exclude a few chips/revisions (5700, 5788) from using the
enhanced version and fall back to the old way as that is the only
method they support.

The seekdir shall set the position for the next readdir operation.
When the _readdir_unlocked() encounters deleted entry, dd_loc is
already advanced. Continuing the loop leads to premature read of
the target entry.

ALT_BREAK_TO_DEBUGGER. In addition to "Enter ~ ctrl-B" (to enter the
debugger), there is now "Enter ~ ctrl-P" (force panic) and
"Enter ~ ctrl-R" (request clean reboot, ala ctrl-alt-del on syscons).
We've used variations of this at work. The force panic sequence is
best used with KDB_UNATTENDED for when you just want it to dump and
get on with it.
The reboot request is a safer way of getting into single user than
a power cycle. eg: you've hosed the ability to log in (pam, rtld, etc).
It gives init the reboot signal, which causes an orderly reboot.
I've taken my best guess at what the !x86 and non-sio code changes
should be.
This also makes sio release its spinlock before calling KDB/DDB.
which are also likely to be irrelevant for sun4v (there's no SBus on sun4v
