Make alpha_wmb() actually a WMB rather than an MB (all uses of
alpha_wmb() have been audited and fixed-up as necessary).

In order to prevent _mcount() from being recursively called when built with COPTS=-O0,
sprinkle `__always_inline' to make _mcount() be generated as a single function.

Define the arithmetic exception summary bits passed in a0 to entArith.

Fix the bit position for the PMI bit in ALPHA_AMASK_BITS.

Add alpha_pal_wtint(), which invokes the WTINT PALcode call.

- Document all of the various interrupt levels in the Processor Stataus
register, and provide symbolic names for them as well.
- Use ALPHA_PSL_IPL_* values directly for IPL_*.

Do a minor cleanup of alpha (this will make applying pullups post branching
easier).

Enable Pchip and Cchip error interrupts (machine checks) on DEC 6600
systems. Add some basic pretty-printing for those errors. Tested on
a DS20.

Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

merge ktrace-lwp.

Added a new AMASK bit (ALPHA_AMASK_PMI) and a new IMPLVER family ID:
ALPHA_IMPLVER_EV7.

Merge the nathanw_sa branch.

Add a memory clobber to alpha_pal_swapctx() and alpha_pal_swpipl();
the former affects the address space, and the latter can let interrupt
handlers in to clobber memory.

Protect userland from the inlines and kernel variable decls.

And more ANSI'ification!

ANSI'ify.

Fix a typo in a previous revision, and add bit names for amask bits for
use with bitmask_snprintf().

Update the amask bits.

Use ANSI-style function declarations for the various inline functions
here. Addresses port-alpha/9056.

Inline most of the remaining PALcode calls.

Inline the BWX instructions.

Move atomic operations into <machine/atomic.h>, and make them in-line
assembly, rather than function calls.

After reading the GCC `documentation' a little more, improve the inline
__asm() statements added previously for PALcode operations.

Inline several things from pal.s:
- alpha_rpcc(), alpha_mb(), alpha_wmb() -- these are instructions, and
we win by inlining them: rpcc is generally used for profiling, and
the memory barriers rea

Inline several things from pal.s:
- alpha_rpcc(), alpha_mb(), alpha_wmb() -- these are instructions, and
we win by inlining them: rpcc is generally used for profiling, and
the memory barriers really should execute as quickly as possible with
minimal side-effects (like additional loads/stores required to call the
functions!)
- alpha_pal_imb(), alpha_pal_rdps(), alpha_pal_swpipl(), alpha_pal_tbi(),
alpha_pal_whami() -- these are PALcode ops. We must specify some register
clobbers for these.

We have a very decent size savings as a result. My test system:
text data bss dec hex filename
2671724 235848 377016 3284588 321e6c /netbsd.bak
2617708 235736 377016 3230460 314afc /netbsd

Most of this comes from fewer register saves/restores around spl*() calls
(now that alpha_pal_rdps() and alpha_pal_swpipl() are inlined).

Note that alpha_pal_rdps() and alpha_pal_swpipl() remain in pal.s to
maintain binary compatibility with LKMs that may use spl*() functions.
