It seems that `options GZIP` and `options ZFS` collide because they both
define inconsistent definitions for inflate, etc
Fixing this will require upgrading zlib in the kernel, as suggested in
r245102.

problem that led to this temporary workaround (and also so I can properly
cite the PR in the commit this time).
In general this is intended to be a temporary workaround until we can figure
out why including any ram from the last megabyte of the physical address
space leads to a NULL pointer deref. Debugging that is made trickier by the
fact that I couldn't even get a backtrace in ddb.

For rs6000, most memory insns and addi/addis do not allow GPR0 for RA

sure to have a base register other than GPR0.
GCC-4.7 and up handles this with allocating r9 instead of r0.
to generate the phys_avail and dump_avail arrays.
This is a partial fix for the kernel side of the problem mentioned in the
PR. This part handles the cases where comparing start and end addresses of
a block would fail because 32-bit wrap caused the end address to come out
zero if the end of the region is the end of the address space (0xffffffff
with 32-bit vm_paddr_t, but now the code should also work right if we ever
support LPAE with 36-bit addresses).
More work is necessary to make systems with ram at the end of the physical
address space usable, but at least initially it's going to be more like a
workaround than a fix, so this non-hacky part is being committed first.

unmount of devfs mounts, by restarting the failed syscall.
When restarted, failing syscalls eventually either stop finding the
node and returning ENOENT, or the vnode op vectors finally transition
to the deadfs vop. The later return EIO or other error, more
appropriate for the operation.

tree parsing opt-out rather than opt-in. All FDT-based systems as well as
PowerPC systems with real Open Firmware use the CHRP-derived binding that

a problem on 32-bit systems which have ram occupying the end of the physical
address space -- for example, a block of ram at 0x80000000 with a size of
0x80000000 was overflowing 32 bit math and ending up with a calculated size
of zero.
This is a fix for one of the two problems mentioned in the PR. Something
similar will need to be done on the kernel side before the PR is closed.

The ath hal and driver code all assume the world is an x86 or the
bus layer does an explicit bus flush after each operation (eg netbsd.)
However, we don't do that.
So, to be "correct" on platforms like sparc64, mips and ppc (and maybe
ARM, I am not sure), just do explicit barriers after each operation.
Now, this does slow things down a tad on embedded platforms but I'd
rather things be "correct" versus "fast." At some later point if someone
wishes it to be fast then we should add the barrier calls to the HAL and
driver.

providing compiled-in static environment data that is used instead of any
data passed in from a boot loader.
Previously 'env' worked only on i386 and arm xscale systems, because it
required the MD startup code to examine the global envmode variable and
decide whether to use static_env or an environment obtained from the boot
loader, and set the global kern_envp accordingly. Most startup code wasn't
doing so. Making things even more complex, some mips startup code uses an
alternate scheme that involves calling init_static_kenv() to pass an empty
buffer and its size, then uses a series of kern_setenv() calls to populate
that buffer.
Now all MD startup code calls init_static_kenv(), and that routine provides
a single point where envmode is checked and the decision is made whether to
use the compiled-in static_kenv or the values provided by the MD code.
The routine also continues to serve its original purpose for mips; if a
non-zero buffer size is passed the routine installs the empty buffer ready
to accept kern_setenv() values. Now if the size is zero, the provided buffer
full of existing env data is installed. A NULL pointer can be passed if the
boot loader provides no env data; this allows the static env to be installed
if envmode is set to do so.
Most of the work here is a near-mechanical change to call the init function
instead of directly setting kern_envp. A notable exception is in xen/pv.c;
that code was originally installing a buffer full of preformatted env data
along with its non-zero size (like mips code does), which would have allowed
kern_setenv() calls to wipe out the preformatted data. Now it passes a zero
for the size so that the buffer of data it installs is treated as
non-writeable.
When gssd exits it leaves the kernel state set by
gssd_syscall(). nfsd sees this and waits endlessly
in an unkillable state for gssd to come back. If you
had acidentally started gssd then stopped it, then
started nfsd you'd be in a bad way until you either
restarted gssd or rebooted the system. This change
fixes that by setting the kernel state to "" when
gssd exits.

LBC block size can only be up to 4GB. The existing code already clamps it, but
mixes unsigned long and uint32_t. This works on 32-bit targets, but not 64-bit,

libstand is built in three places (lib/libstand, sys/boot/libstand32,

sys/boot/userboot/libstand/Makefile will be addressed later, as it
contains additional differences yet to be handled.
This change also switches libstand32 to use the new uuid_from_string

we're assuming hz=1000 and not gracefully handling when it isn't.
The math involved will return 0 for hz < 1000, which it is on some
platforms and on DragonflyBSD.
This doesn't fix it, it:
* converts one manual use over to use the macro, and

I'll think about this a bit more before fixing it.
