While this is generally good, it brings along a serie of problems,
like clocks going off sync and in presence of SW_WATCHDOG, watchdogs
firing without a good reason (missed hardclock wdog ticks update).
Fix the latter by kicking the watchdog just before to re-enable the interrupts.
Also, while here, not rely on users to stop the watchdog manually when
entering DDB but do that when entering KDB context.

function (a hook necessary for gdb support), is inlined, but since the
function contains no code, no calls to it are generated. When gdb is
debugging a dynamically linked program, this causes backtraces to be
corrupted.
Fix it by marking the function __noinline, and inserting an empty asm
statement, that pretends to clobber memory. This forces the compiler to
emit calls to r_debug_state() throughout rtld.c.

and the new setmode and setowner fileops in FreeBSD 9.0:
- Add new MAC Framework entry point mac_posixshm_check_create() to allow
MAC policies to authorise shared memory use. Provide a stub policy and
test policy templates.
- Add missing Biba and MLS implementations of mac_posixshm_check_setmode()
and mac_posixshm_check_setowner().
- Add 'accmode' argument to mac_posixshm_check_open() -- unlike the
mac_posixsem_check_open() entry point it was modeled on, the access mode
is required as shared memory access can be read-only as well as writable;
this isn't true of POSIX semaphores.
- Implement full range of POSIX shared memory entry points for Biba and MLS.

The value of namlen is copied from on-disk d_namlen, which is a 8-bit
unsigned integer which can never exceed MAXNAMLEN (255) so the test is
always true. Moreover, UFS does not allow d_namelen being zero.
Change namlen from u_int to u_int8_t, and replace the unneeded test
with a useful test.

Additional fix to issue 168 because the change of r3642 was not sufficient.

should be connected with.
- Give consideration to the case that the top level "RE" entry has

accessible:
(1) Always compile in support for breaking into the debugger if options
KDB is present in the kernel.
(2) Disable both by default, but allow them to be enabled via tunables
and sysctls debug.kdb.break_to_debugger and
debug.kdb.alt_break_to_debugger.
(3) options BREAK_TO_DEBUGGER and options ALT_BREAK_TO_DEBUGGER continue
to behave as before -- only now instead of compiling in
break-to-debugger support, they change the default values of the
above sysctls to enable those features by default. Current kernel
configurations should, therefore, continue to behave as expected.
(4) Migrate alternative break-to-debugger state machine logic out of
individual device drivers into centralised KDB code. This has a
number of upsides, but also one downside: it's now tricky to release
sio spin locks when entering the debugger, so we don't. However,
similar logic does not exist in other device drivers, including uart.
(5) dcons requires some special handling; unlike other console types, it
allows overriding KDB's own debugger selection, so we need a new
interface to KDB to allow that to work.
GENERIC kernels in -CURRENT will now support break-to-debugger as long as
appropriate boot/run-time options are set, which should improve the
debuggability of BETA kernels significantly.
