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.

"Upon successful completion, initstate() and setstate() shall return a
pointer to the previous state array; otherwise, a null pointer shall
be returned.
Although some implementations of random() have written messages to
standard error, such implementations do not conform to POSIX.1-2008."

The contrib/top code is no longer maintained upstream (last pulled 16 years
ago). The K&R-style followed by the code spews -Wimplicit-int and -Wreturn-type
warnings, amongst others. This silences 131 warnings with as little modification
as possible by adding necessary return types, definitions, headers, and header
guards, and missing header includes.
The 5 warnings that remain are due to undeclared ncurses references. I didn't
include curses.h and term.h because there are several local functions and macros
that conflict with those definitions.

The GPIO hardware should not be owned by a single device, this defeats any
chance of use of the GPIO controller as an interrupt source.

Fix some rather complex regex issues found on OpenBSD as part of some
ongoing work to fix a sed(1) bug.
Curiously the OpenBSD tests don't trigger segfaults on FreeBSD but the
bugs were confirmed by running a port of FreeBSD's regex under OpenBSD's
malloc. Huge thanks to Ingo for confirming the behavior.

This is a long standing problem: our random() function returns an
unsigned integer but the rand provided by ndis(4) returns an int.
Scale it down.
MFC after: 2 weeks
In ndis(4) we expose a rand() function that was constantly reseeding
with a time depending function every time it was called. This
essentially broke the reasoning behind seeding, and rendered srand()
a no-op.
Keep it simple, just use random() and srandom() as it's meant to work.
It would have been tempting to just go for arc4random() but we
want to mimic Microsoft, and we don't need crypto-grade randomness
here.

compilers can emit arm instructions that require 8-byte alignment. The
alignment-sensitive instructions were added in armv5, which has to be
supported by our combined v4/v5 kernels, so the value is set uncoditionally
for all arm architecture versions.
Also adjust the comment to explain in more detail why the macros have the
form and values they do.
Per advice from bde@, maintain the unsignedness of the value of _ALIGNBYTES
(but do so using his second choice of allowing sizeof() to supply the
unsignedness, rather than just hardcoding '8U', which in my mind would
require an even more verbose comment to explain why it's right). Also
explain in the comment that the resulting type of _ALIGN() is equivelent
to uinptr_t on arm (32-bit unsigned int), but it's purposely spelled as
"unsigned" to avoid problems with including other header files. Even
including machine/_types.h to allow use of __uintptr_t causes compilation
failures because of this header being included (indirectly) in asm code.
