9184fb847b Optimize bzero() by unrolling the aligned quadword loop and moving the length
manipulation away from the length comparison.  Measurements on beast.cdrom.com
show >3X improvement over the original code on large block sizes, putting the
performance on par with the optimized assembly code in libc.

57250ffb42 * Fix vga_probe() so that it doesn't report a non-vga display adapter as
a vga.
* Fix broken logic in syscons for a failed probe.
* Fix AlphaStation 500/600 so that non-serial consoles are supported.

35d27a0f39 Add the ability to specify where on the at_shutdown queue a handler is
installed.

Remove cpu_power_down, and replace it with an entry at the end of the
SHUTDOWN_FINAL queue in the only place it's used (APM).

522bda27ae Fix this correctly - check if mfs_getimage() succeeds before settings
the MFS root unconditionally, just as on the x86.

4df550a942 Take MFS_ROOT out for now; for some reason, the alpha GENERIC chokes
and dies if it can't find the MFS root whereas the x86 one seems to sail
past.  Looking at the code, I can't see how either one works, so I'm
confused. :)

aa855a598d *gulp*. Jordan specifically OK'ed this..
This is the bulk of the support for doing kld modules.  Two linker_sets
were replaced by SYSINIT()'s.  VFS's and exec handlers are self registered.
kld is now a superset of lkm.  I have converted most of them, they will
follow as a seperate commit as samples.
This all still works as a static a.out kernel using LKM's.

da6c15d597 Initial attempt to update the Alpha loader and kernel to use the machine
independent elf loader and have access to kld modules.  Jordan and I were
not sure how to create boot floppies, and the things we tried just made
SRM laugh in our faces - but it was upset at boot1 which was not touched
by these changes.  Essentially this has been untested. :-(

What this does is to steal the last three slots from the nine spare longs
in the bootinfo_v1 struct to pass the module base pointer through.

The startup code now to set up and fills in the module and environment
structures, hopefully close enough to the i386 layout to be able to use
the same kernel code.  We now pass though the updated end of the kernel
space used, rather than _end. (like the i386).

If this does not work, it needs to be beaten into shape pronto.  Otherwise
it should be backed out before 3.0.

514058dc0d Unregister the glibc2 brand at module unload time.
Change the ELF registration/unregistration scheme to be less error prone.
Adding a new brand requires a single addition to linux_brandlist instead of
modifying linux_load(), linux_unload(), and linux_elf_init().

also on the Multia (mine hasn't arrived yet, so I can't tell for sure).
