Unlike in an i386 a.out assembler, where in an .align n directive n is meant
...
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.
Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.

completely remove Mach VM support. all that is left is the all the
...
header files as UVM still uses (most of) these.

Use _C_LABEL() to generate C labels in assembly code, don't prepend an
...
underscore (_) directly. (XXX Except in a few places, where traditional
CPP's macro evaluation semantics break things, so we test for __ELF__
directly in those places).

Fix a condition where we might keep interrupts blocked while servicing a soft

interrupt.
Fixes serial port silo overflow problems.

Import interrupt priority changes from com patches:
...
* Make it a strict hierarchy. (It was close anyway).
* Add `serial' and rename `softtty' to `softserial'.
* Make soft interrupts a bit less special-case.

* Add old-style vmstat -i interrupt counters for normal and stray interrupts.
...
Interrupts for irqs with handlers are counted as normal, even if none of
the handlers claim the interrupt.
Should all be redone with hierarchical event counters. that count
hardware events and invocations of each handler separately.
* Increment cnt.v_intr for normal interrupts (bugfix).

The previous optimization only works for edge-triggered interrupts...

By default, don't frob the ICU masks here. The software masking should

clean up several ISA device interfaces: autoconfiguration, header

change interrupt vector names to begin with "X" rather than "V", so we're

like every other BSD system on the planet...

Unless INTR_DEBUG is set, don't report all of the "random" event types.
...
also, unless INTR_DEBUG is set, make the internal branch labels for
the interrupt code be local labels, so profiling works OK.

Backed out the changes to the FAST_VECTOR code that were made in the

previous revision, as they apparently broke something.

Neatened up the AUTO_EOI conditionals. FAST_VECTOR() now saves & restores

the ES register, just to be on the safe side (since ES is used in some
locore routines).
