a5b6b9a68e Fix the triple fault used as a last resort during a reboot to actually 
fault.  The previous method zero'd out the page tables, invalidated the
TLB, and then entered a spin loop.  The idea was that the instruction after
the TLB invalidate would result in a page fault and the page fault and
subsequent double fault wouldn't be able to determine the physical page
for their fault handlers' first instruction.  This stopped working when
PGE (PG_G PTE/PDE bit) support was added as a TLB invalidate via %cr3
reload doesn't clear TLB entries with PG_G set.  Thus, the CPU was still
able to map the virtual address for the spin loop and happily performed
its infinite loop.

The triple fault now uses a much more deterministic sledge-hammer approach
to generate a triple fault.  First, the IDT descriptor is set to point to
an empty IDT, so any interrupts (including a double fault) will instantly
fault.  Second, we trigger a int 3 breakpoint to force an interrupt and
kick off a triple fault.

4cc968cb95 MFi386: Attempt to reset the machine using the Reset Control register and 
Fast A20 and Init register if the keyboard reset doesn't work before
resorting to a triple fault.

1e788bd7e5 ZIL (ZFS Intent Log) can be safely turned on and off at run time, because 
it is only used when dataset is beeing mounted to decide if log should also
be opened.

f13f738876 MFp4: Rearange the code so vobject is destroyed from reclaim() method like 
in all other file system on FreeBSD (instead from inactive() method).

A nice side-effect of this change, except that it speedups file system
when mmaped file are often open/closed, is that it makes FreeBSD's
namecache work:)

0cdad5e228 MFp4: Once page is written successfully, we should clear the dirty bits. 
This fixes slow operations on mmaped files, because without this fix,
pages were written to disk multiple times.

If one is looking for even greater speed up for such operation, he should
disable ZIL (by setting vfs.zfs.zil_disable to 1 in /boot/loader.conf).
Disabling ZIL makes fsx run ~9 times faster.

3629c47471 Nuke unnecessary setting of ural(4)'s security registers. ural(4) only
