XXX: I didn't add 'mbroffset' support for a GPT partition holding a BSD

o Disklabels can have between 8 and 20 partitions (inclusive).
o No device special file is created for the raw partition.
o Switch ia64 to use this backend.
o No support for boot code yet.
- Missing lock when sending data and moving it to the
outqueue.
- If a mbuf alloc fails during moving to outqueue the
reassembly of the old mbuf chain was incorrect.
- some_taken becomes a counter in sctputil.c instead of a set to 1.
- Fix a panic to be only under invarients and have a proper recovery.
- msg_flags needed to be set.to the value collected not or'd.

Aquire Giant slightly later for vnlru.
In the syncer, aquire the Giant only when a vnode belongs to the
non-MPsafe fs.
In both speedup_syncer() and syncer_shutdown(), remove the syncer thread from
the lbolt sleep queue after the syncer state is modified, not before.

This makes updates mounts such as:
"mount -u -o rdonly" work more like, "mount -u -o ro".
References to "-o rdonly" were changed to "-o ro" in revision 1.60 of
the mount(8) man page,
but some people still like to use "-o rdonly" since it was documented
in earlier versions of FreeBSD.

within the jail are never freed. si_cred is only used by the MAC framework so
make the cred reference conditional on it being compiled in, this is not a fix
and will need to be reviewed for any new consumers of si_cred.
This will quell some user complaint when using jails with a default kernel.

sending, once the locks are all unlocked to
do the copy's in, its possible that other
events could then raise the number of bytes
outstanding pushing it so not all the message
would fit. This would then cause us to send
only part of the message. This fix makes it
so we keep a "reserved" amount that can be
kept in mind when making calculations to send.
- rcv msg args with a NULL/NULL for to/tolen will return an error incorrectly
for the 1-2-1 model.
- We were not doing 0 len return correctly and not setting cantrcv more
correctly. Previouly we "fixed" this area by taking out the socantrcv
since we then could not get the data out. The correct rix is to still
flag the socket but alow a by-pass route to continue to read until
all data is consumed.

with insufficient protection mode.
For the i386 and amd64, create the tunable, machdep.prot_fault_translation,
with the following behaviour:
0 = autodetect the signal to be delivered on KERN_PROTECTION_FAILURE
from vm_fault based on the ELF OSABI note:
no note or __FreeBSD_version < 700004 - SIGBUS/BUS_PAGE_FAULT
note, and __FreeBSD_version >= 700004 - SIGSEGV/SEGV_ACCERR
1 = always SIGBUS/BUS_PAGE_FAULT
2 = always SIGSEGV/SEGV_ACCERR
This would do mostly automatic correction of ABI breakage, with the exception
of the untaged binaries for 7-CURRENT/RELENG_7 before the note is fixed. For
them, sysctl would allow to run the binary with manual settings.

support its -k argument:
kern.proc.kstack - dump the kernel stack of a process, if debugging
is permitted.
This sysctl is present if either "options DDB" or "options STACK" is
compiled into the kernel. Having support for tracing the kernel
stacks of processes from user space makes it much easier to debug
(or understand) specific wmesg's while avoiding the need to enter
DDB in order to determine the path by which a process came to be
blocked on a particular wait channel or lock.
