- Support for setting memory range attributes on SMP systems using the
new SMP rendezvous function
- Don't print the confusing default memory type message.
- Allow legal overlapping range types.
- Turn interrupts back on after setting MTRRs in UP mode (whoops)
- Don't waste time calling invltlb() after wbinvd(); it's not
SMP-compatible (interrupts are off) and unncessary because
wbinvd already flushes the TLB.
This code is now essentially feature-complete.
the caller to specify a function to be guarded between an entry and exit
barrier, as well as pre- and post-barrier functions.
The primary use for this function is synchronised update of per-cpu private
data. The implementation is almost (but not quite) MI; with a better
mechanism for masking per-CPU interrupts it could probably be hoisted.

the right way: Store the actual pathname in the kernel like mount
does. [Volounteers sought for this task]
The road map from here is roughly: expand struct specinfo into struct
based dev_t. Add dev_t registration facilities for device drivers and
start to use them.

Also fix the rambuffer offset initialization for the 512K/64K SRAM case
(512K total using 64K chips). It should be 0. The only case with a
non-standard rambuffer offset address is 1024K/64K according to the
SysKonnect manual. (My card has the 1024/64 configuration and I don't know
which card uses the 512/64 configuration, if any, so I'm not sure that
this was really a problem for anyone.)

to egcs 1.1.2 produced at least one non-atomic code sequence in

portability between SMPs and UPs, modules are compiled with the SMP-safe
versions.)
