48ff19c98b u_char -> u_int for function argument and return of Zilog register
manipulation helper functions; no loss, no gain, for Alpha processor.

9c5afcb2f0 Move the Alpha _mcount() into a .S file so that it can be
pre-processed, like other Alpha assembly files.

0778dad08f Define the biglock perimeter for the Alpha port, and generally clean
up a bunch of the MP code.  Still doens't work properly yet, this is
just a snapshot of work-in-progress.

4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

51a53de0d5 Preparation for the future introduction of multibyte locale.
- MB_LEN_MAX is increased to 32.
 - To ensure binary compatibility for old executables
   under multibyte locale, versioned setlocale is added.
 - __mb_len_cur definision is added in setlocale.c
   and enable it in stdlib.h .
   It is also important for multibyte locale stuffs,
   but I just forgot.

889c658b5b Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

c2ebb05a74 make spl0() and spllowersoftclock() return void. Also, move spl0()

e59356ecdd In __cpu_simple_lock_try(), use "return (v0 != 0);" instead of
"return (v0);" where v0 is an unsigned long and the function return
type is int.  Stops lint warnings when this file is included.

cd423732b8 - Clean up clock interrupt code a bit, and provide a CPU_IS_PRIMARY()

47449a63d2 kill __P in these files. (I had to look at them anyway with an eye for
adding some protos... and adding them with __P seems wrong, but mixing

0d866249d4 - In the MULTIPROCESSOR case, initialize p_cpu before a process is
marked SONPROC.
- Always make curproc, fpcurproc, astpending, and want_resched per-CPU
  variables in struct cpu_info.  Restructure code accordingly, and trim
  a few instructions from a few spots in various places in locore.

a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.
