is 4e2cf3688b fpu_emulate.h:
the fmovecr constant table has the internal format
  of the constants. So, when changing the mantissa size by a
  non-multiple of 32 bits, we'd have to change this table, too. As
  all other code changes just chopped of the least significand
  32bit word of the mantissa, we correct the mantissa size instead
  to (115 - 32 == 83) bits.
fpu_fmovecr.c:
  put a safety belt in, to catch the next person who doesn't know this.
fpu_int.c:
  in one place, the reduction of the mantissa size was overlooked.
fpu_log.c:
  as the most significand 32bit word of the mantissa was changed back to the
  old format, change back the table indexing code, too.

This should fix PR 11045.

scw 0dc48bfa8f Add a `/t' modifier to the m68k ddb's `trace' command. This enables
one to perform a kernel traceback of any (non-swapped-out) process in
the system. For example, to show the traceback for PID 178:

  db> t/t 0t178
  trace: pid 178 at 0xabcd68
  _mi_switch(0x109f60) + 164
  ...
  db>

tshiozak 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.

itojun d738f90fd7 raise MSIZE from 128 to 256.
- for sizeof(void *) == 8 arch, this is mandatory.  MHLEN is too small
  already (less than 80) and there are chances for unwanted packet loss due
  to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
  (even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
  extension header)

portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

thorpej 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.

jhawk 8e44b27348 Rename the machine-specific stack trace printing functions
from db_stack_trace_cmd() to db_stack_trace_print(),
and add an additional argument, a function pointer for an
output routine (i.e. printf() or db_printf()).

Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.

Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].

Again, I'm unable to test compilation on all affected platforms,
so advance apologies for potential brokenness.

thorpej 39f8e55cfc On the m68k, the most efficient type for __cpu_simple_lock_t is
an unsigned char, since that is what the `tas' instruction uses.

While I'm here, implement the __cpu_simple_lock family of routines.
Why?  One, because they're easy.  Two, so Steve can get master/slave
MVME systems talking across the backplane.  :-)

thorpej 855b79db92 Let each platform typedef the new __cpu_simple_lock_t, which should
be the most efficient type used for the atomic operations in the
simplelock structure, and should also be __volatile.

thorpej f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

kleink 230876cf26 Merge parts of chs-ubc2 into the trunk:
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.
