install from USB media to succeed without any user interaction if there is
exactly one USB disk device in the system it can use.

Check that the given variable is at most uintptr_t in size and that
it is aligned.
Note: ASSERT_ATOMIC_LOAD() uses ALIGN() to check for adequate
alignment -- however, the function of ALIGN() is to guarantee
alignment, and therefore may lead to stronger alignment
enforcement than necessary for types that are smaller than
sizeof(uintptr_t).
Add checks to mtx, rw and sx locks init functions to detect possible
breakage. This was used during debugging of the problem fixed with
r196118 where a pointer was on an un-aligned address in the dpcpu area.

- Provide lapic_disable_pmc(), lapic_enable_pmc(), and lapic_reenable_pmc()
routines in the local APIC code that the hwpmc(4) driver can use to
manage the local APIC PMC interrupt vector.
- Do not enable the local APIC PMC interrupt vector by default when
HWPMC_HOOKS is enabled. Instead, the hwpmc(4) driver explicitly
enables the interrupt when it is succesfully initialized and disables
the interrupt when it is unloaded. This avoids enabling the interrupt
on unsupported CPUs which may result in spurious NMIs.

checkout. If SVNROOT is specified, then the source tree will be checked
out from that SVN repository instead of using CVS. ports and docs still
use CVS. If SVNROOT is not specified, then the source tree will be checked
out using CVS. An explicit SVN branch can be specified using SVNBRANCH
(e.g. SVNBRANCH=stable/8). If SVNBRANCH is not set but RELEASETAG is set
to a CVS branch (such as RELENG_8) the appropriate SVN branch will be
inferred from the CVS branch using svnbranch.awk.
Note that there are still several open questions about using SVN instead
of CVS in the release process. However, this does enable one to build a
release from an SVN repository if needed.

When downgrading, pass LK_RETRY to the vn_lock(), since otherwise

Receiving any ip packet for which there is no existing socket will
crash if ipfw has a uid or gid test rule, as the uid/gid
of the non existent owner of said non existent socket is tested.
Brooks introduced this error as part of his >16 gids patch.
It appears to be a cut-n-paste error from similar code a few lines
before. The old code used the 'pcb' variable here, but in the
new code that switched the 'inp' variable, which is often NULL
and what is tested in the code further up. The rest of the multi-gid
patch for ipfw seems solid (and cleaner than previous code).

has proven to have a good effect when entering KDB by using a NMI,
but it completely violates all the good rules about interrupts
disabled while holding a spinlock in other occasions. This can be the
cause of deadlocks on events where a normal IPI_STOP is expected.
* Adds an new IPI called IPI_STOP_HARD on all the supported architectures.
This IPI is responsible for sending a stop message among CPUs using a
privileged channel when disponible. In other cases it just does match a
normal IPI_STOP.
Right now the IPI_STOP_HARD functionality uses a NMI on ia32 and amd64
architectures, while on the other has a normal IPI_STOP effect. It is
responsibility of maintainers to eventually implement an hard stop
when necessary and possible.
* Use the new IPI facility in order to implement a new userend SMP kernel
function called stop_cpus_hard(). That is specular to stop_cpu() but
it does use the privileged channel for the stopping facility.
* Let KDB use the newly introduced function stop_cpus_hard() and leave
stop_cpus() for all the other cases
* Disable interrupts on CPU0 when starting the process of APs suspension.
* Style cleanup and comments adding

of a short RPC reply. When this happens, xdrmbuf_getbytes() returns
success, but advances the mbuf ptr (xdrs->x_private) to m_next, which
is NULL. If this is followed by a call to xdrmbuf_getlong(), it calls
xdrmbuf_inline(), which would cause a crash by accessing "m->m_len".
