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.

Port of the hotplug CPU changes from i386 for x86-64.  I don't expect
x86-64 hardware to support CPU hotplugging any time soon, but this makes
it all compile & work again and keeps some consistency.

Update various lib/ functions for x86-64:

 - new memcpy/memset/csum-copy/copy_page/user
 - add bitstr support function for IOMMU
 - Other minor fixes and updates.

Merge from i386 for x86-64: move reboot functions to an own file.

Straightforward merge from i386: remove support for global cli for
x86-64
