Fix some bugs that would prevent %fsr to be set correctly, and add
support for fcmp and fcmpe instructions with a condition code
specification other than %fcc0.
This (primarily the first part) seems to fix a lot of problems that
people were seeing, e.g. perl and gawk failures.

Save/restore the %y register around calls to the C user trap handler;

Export a (machine dependent) kernel variable bootdev as
machdep.guessed_bootdev, and add code to sysctl to parse its value
and give a (not necessarily correct) name to the device we booted
from (the main motivation for this code is to use the info in the
PicoBSD boot scripts, and the impact on the kernel is minimal).
NOTE: the information available in bootdev is not always reliable,
so you should not trust it too much. The parsing code is the same
as in boot2.c, and cannot cover all cases -- as it is, it seems to
work fine with floppies and IDE disks recognised by the BIOS. It
_should_ work as well with SCSI disks recognised by the BIOS.
Booting from a CDROM in floppy emulation will return /dev/fd0 (because
this is what the BIOS tells us).
Booting off the network (e.g. with etherboot) leaves bootdev unset so
the value will be printed as "invalid (0xffffffff)".
Finally, this feature might go away at some point, hopefully when we
have a more reliable way to get the same information.

Fix a breakage introduced in rev.1.75 (supposedly style cleanup), which results
in "missing dependencies" error when loading some kld modules. It is sad to
see how often these days style cleanus break doesn't broken things. Perhaps
people should recall good old principle: "don't fix it if it isn't broken".

__FreeBSD__ is a compiler predefine,
__FreeBSD_version is defined in <sys/param.h> .
Given that in this case (and all others in sys/dev/usb and sys/i4b)
the goal is to adapt to a different kernel interface, and not to
a compiler feature, I believe the correct form is the second one
(in the best case the two are synonyms so the change does not break
anything anyways).

the number of physical pages per KVA page allocated scales properly with

Change back to using vfork() now that execvp() is vfork()-safe. If execvp()
fails, errno is saved to a volatile variable that the parent later inspects.

Don't use pool mutexes for pipes. We can not use pool mutexes

Revert change in revision 1.53 and add a small comment to protect
the revived code.
vm pages newly allocated are marked busy (PG_BUSY), thus calling
vm_page_delete before the pages has been freed or unbusied will
cause a deadlock since vm_page_object_page_remove will wait for the
busy flag to be cleared. This can be triggered by calling malloc
with size > PAGE_SIZE and the M_NOWAIT flag on systems low on
physical free memory.
A kernel module that reproduces the problem, written by Logan Gabriel
<logan@mail.2cactus.com>, can be found in the freebsd-hackers mail
archive (12 Apr 2001). The problem was recently noticed again by
Archie Cobbs <archie@dellroad.org>.
