Rework the interrupt code, shaving some cycles off in the process.
...
Rather than an "iointr" routine that decomposes a vector into an
IRQ, we maintain a vector table directly, hooking up each "iointr"
routine at the correct vector. This also allows us to hook device
interrupts up to specific vectors (c.f. Jensen).
We can shave even more cycles off, here, and I will, but it requires
some changes to the alpha_shared_intr stuff.

Switch to the new `evcnt' mechanism for counting interrupts. Maintain
...
a per-CPU interrupt counter for clock, device, and interprocessor
interrupts.

Point back to the alpha_shared_intr in the intrhand structure. This
...
allows platform-specific code to access the `intr_private' data via
the intrhand structure.

Allow (re)setting of maxstrays after establishment of a shared interrupt.
...
This allows sporadic stray interrupt counts to be reset by an acknowledgement
of the same interrupt.

Implement alpha_shared_intr_disestablish(). Simply removes the handler

fromthe list, allowing the caller to manipulate the sharing type,
if appropriate.

Always count the number of strays we encounter, but don't send a "stopped

by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
...
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
