This patch fixes a typo introduced by my last patch to dv1394.

This adds the dmask option. Yes, the dmask option is the permission
bitmask for directory.

This adds fat_show_options() to fat. And instead, this doesn't output
the charset name in fat_fill_super().

This removes the posix option of vfat. The current posix options works
only as an alias of name_check=s.

This merges parse_options() of fat and parse_options() of vfat.
And this doesn't recognize the unknown options.

This fixes the error code which fat_fill_super() returns.

 - Cleanup (purge) some of our old compat code (never thouched)
 - Fix dv1394 compilation warnings without devfs
 - Added new config-rom handling features. Allows for on-the-fly
   config-rom generation for dynamic functionality of the host nodes.
 - Convert to workqueue from taskqueue interfaces. This is actually
   abstracted compatibility code between tqueue/workqueue.

To my suprise a lot of big site/beowulf type people all really want this
diff, which I'd otherwise filed as 'interesting but not important'

(someone really needs to indent the cpqfc driver!)

The _ isnt allowed in a docbook id

of gcc incorrectly accepted as "short". It got fixed to __u8, but
it really should be __u16.

And here all the other x86-64 changes that have accumulated in my tree.

It's various bugfixes and cleanups.

Changes:

 - fix nmi watchdog
 - remove local timer spreading over CPUs - it's useless here and caused many problems
 - New offset.h computation from Kai
 - Lots of changes for the C99 initializer syntax
 - New MTRR driver from Dave & Mats
 - Bugfix: kernel threads don't start with interrupts disabled anymore, which fixes
   various boottime hangs (this was fixed a long time ago, but the bug crept in again
   by the backdoor)
 - Do %gs reload in context switch lockless
 - Fix device_not_available entry point race
 - New per CPU GDT layout following i386: the layot is not completely
   compatible with i386, which may problems with Wine in theory.
   Haven't seen any yet.
 - Support disableapic option
 - driverfs support removed for now because it caused crashes
 - Updates for new signal setup
 - Support for kallsyms
 - Port TLS clone flags/syscalls: unfortunately made the context switch
   even uglier than it already is.
 - Security fixes for ptrace
 - New in_interrupt()/atomic setup ported from i386
 - New makefiles mostly from Kai
 - Various updates ported from i386

Some timer updates from Vojtech Pavlik for x86-64.  In theory support
HPET timing now, but the support is disabled.

Would actually need vxtime_lock() macros in the generic timer code to
protect xtime updates, but I'm leaving that out now because it's only
needed for vsyscalls and they're currently disabled.
