low bound, and the number of bytes remaining instead of storing the
raw byte sequence and deriving them every time mbrtowc() is called.
This is much faster -- about twice as fast in some crude benchmarks.
gets the relocation base passed in relocbase, we cannot declare a
local variable with the same name. Assume the argument holds the
same value as the local variable did...
repocopied. Soon there will be additional bus attachments and
specialization for isa, acpi and pccard (and maybe pc98's cbus).
This was approved by nate, joerg and myself. bde dissented on the new
location, but appeared to be OK after some discussion.
constants the wrong way on the VAX. Instead, use C99 hexadecimal
floating-point constants, which are guaranteed to be exact on binary
IEEE machines. (The correct hexadecimal values were already provided
in the source, but not used.) Also, convert the constants to
lowercase to work around a gcc bug that wasn't fixed until gcc 3.4.0.

different context support for 32 vs 64 bit processes. This simply omits
the save/restore of the segment selector registers for non 32 bit
processes. This avoids the rdmsr/rwmsr juggling when restoring %gs
clobbers the kernel msr that holds the gsbase.
However, I suspect it might be better to conditionally do this at
user<->kernel transition where we wouldn't need to do the juggling in the
first place. Or have per-thread extended context save/restore hooks.
hal_raise_irql(void) doesn't take an argument, but it is called with one.
eg: irql = FASTCALL1(hal_raise_irql, DISPATCH_LEVEL);
This is hidden by the macros on i386, but becomes a compile error on amd64
since the arguments are actually checked.
to help the AMD cpus (which have a hardware tlb flush filter). I held
off to see what the 64 bit Intel cpus did, but it doesn't seem to help
much there either. Oh well, store it in the Attic.

Properly encapsulate all user<->kernel data transfers using copy{in,out}.

Otherwise, only the first one present would be probed and attached.
