a4f7863238 Add kexec-based Linux shim loader for use with the firmware petitboot
loader on PS3 and POWER8 systems. This is reasonably portable to other
architectures, especially FDT-based ones, if similar features are useful
elsewhere.

Netboot support is missing for now and will be added in a future commit,
at which time loader.ps3 will be garbage collected.

This adds the initial frequency poking and configures up enough
for it to boot and spit out data over the console.

There's still a whole bunch of work to do in the reset path
and devices to support this thing, but hey, it's alive!

bbae23a725 Eliminate uninitialized variable warnings in kernel and module builds when
building with gcc 4.2

This has been requested several times over the past few months by several
people (including me), because gcc 4.2 just gets it wrong too often.  It's
causing us to litter the code with lots of bogus initializers just to
squelch the warnings.  We still have clang and coverity telling us about
uninitialized variables, and they do so more accurately.

5b326a32ce Prevent live-lock and access of destroyed data in taskqueue_drain_all().
Phabric:	https://reviews.freebsd.org/D1247
Reviewed by:	jhb, avg
Sponsored by:	Spectra Logic Corporation

sys/kern_subr_taskqueue.c:
	Modify taskqueue_drain_all() processing to use a temporary
	"barrier task", rather than rely on a user task that may
	be destroyed during taskqueue_drain_all()'s execution.  The
	barrier task is queued behind all previously queued tasks
	and then has its priority elevated so that future tasks
	cannot pass it in the queue.

	Use a similar barrier scheme to drain threads processing
	current tasks.  This requires taskqueue_run_locked() to
	insert and remove the taskqueue_busy object for the running
	thread for every task processed.

share/man/man9/taskqueue.9:
	Remove warning about live-lock issues with taskqueue_drain_all()
	and indicate that it does not wait for tasks queued after
	it begins processing.

Dmitry Chagin
9f7a06f27e Indeed, instead of hiding the kern___getcwd() bug by bogus cast
in r276564, change path type to char * (pathnames are always char *).
And remove bogus casts of malloc().
kern___getcwd() internally doesn't actually use or support u_char *
paths, except to copy them to a normal char * path.

These changes are not visible to libc as libc/gen/getcwd.c misdeclares
__getcwd() as taking a plain char * path.

While here remove _SYS_SYSPROTO_H_ for __getcwd() syscall as
we always have sysproto.h.

0d203a6065 Create a custom /boot/defaults/loader.conf for ARM. This differs from the
standard file in the following ways:

 - modules_path includes /boot/dtb
 - It doesn't contain 533 lines, of which 500 are either commented out,
   empty, or something_which_doesnt_work_on_arm_anyway=NO

The standard defaults file takes 40+ seconds to process on an arm beaglebone
board.  This one takes just a couple seconds.

This gets installed instead of the original because of the .PATH magic in
the makefile.

clients, hence they might not handle it very well. This change allows

c69537d018 Add a GPIO output mux configuration method.
The AR934x and later (which will turn up eventually) have a new GPIO
output configuration option - a real MUX rather than a "GPIO or this
function."

For now I'm squirreling it away in the CPU code just so it's done -
I may move this to the GPIO layer later.

Specifically, this is required for setting up some boards that have
external receive side LNA (low noise amplifier) that gets switched on/off
by the on-chip wireless MAC.  If we don't add this support for those
boards then we'll end up with really poor performance.

(I don't yet have one of those APs, but it'll likely show up in a week.)

CWARNFALGS.$file centrally so we don't have to have it in all the

Also, always use -Wno-unknown-pragma to (hopefully temporarily) work
around #pragma ident in debug.h in the opensolaris code. Remove some
stale warning suppression that's no longer necessary.

301e1601ad Fix alignment directives in arm asm code after clang 3.5 import.
The ancient gas we've been using interprets .align 0 as align to the
minimum required alignment for the current section.  Clang's integrated
assembler interprets it as align to a byte boundary.  Fortunately both
assemblers interpret a non-zero value as align to 2^N so just make sure
we have appropriate non-zero values everywhere.

110cd60a28 The "vt_suspend_flush_timer()" function is sometimes called locked
which prevents us from doing a "callout_drain()" call. The callout in
question has a lock associated with it and we are not freeing the
callout. That means we can use the "callout_stop()" function to
atomically stop the callback iff the "callout_stop()" function is
called locked. This patch applies proper locking to "callout_stop()"
and replaces a "callout_drain()" with a "callout_stop()".
