Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

__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

moved <machine/sun_disklabel.h> to <dev/sun/disklabel.h>

Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

move some per-cpu data definitions to MI place so that they can be modified
without touching all ports. discussed on tech-kern@.

Rearrange process exit path to avoid need to free resources from different
process context ('reaper').

From within the exiting process context:
* deactivate pmap and free vmspace while we can still block
* introduce MD cpu_lwp_free() - this cleans all MD-specific context (such
as FPU state), and is the last potentially blocking operation;
all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free()
* process is now immediatelly marked as zombie and made available for pickup
by parent; the remaining last lwp continues the exit as fully detached
* MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same
for both 'process' and 'lwp' exit

uvm_lwp_exit() is modified to never block; the u-area memory is now
always just linked to the list of available u-areas. Introduce (blocking)
uvm_uarea_drain(), which is called to release the excessive u-area memory;
this is called by parent within wait4(), or by pagedaemon on memory shortage.
uvm_uarea_free() is now private function within uvm_glue.c.

MD process/lwp exit code now always calls lwp_exit2() immediatelly after
switching away from the exiting lwp.

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.

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.

Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

__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)

Poor sun3 (but not sun3x) has only 31MB KVM address space,
so reduce NKMEMPAGES_MAX_DEFAULT from 64MB to 16MB.
Fixes "panic: ubc_init: failed to map ubc_object" on
TME emulating 3/120 with >16MB RAM.

Should be pulled up to netbsd-6.

Refactoring MD segment related definitions on m68k ports:
- move macro SEGSHIFT, NBSG, and SEGOFFSET from <machine/param.h>
to <machine/pmap.h> where they should belong
- don't use m68k_round_seg() and m68k_trunc_seg() in sun3 pmap sources
and instead define and use sun3_round_seg() and sun3_trunc_seg()
since they are quite pmap implementation dependent

branches: 1.51.78;
merge ktrace-lwp.

bring back the sun3 MAXPHYS definition that has been missing for 8 years.
more recently, we changed to relying on MAXPHYS rather than MAXBSIZE to
limit page cache I/O sizes, and sun3 has been broken since then.

Increase MSGBUFOFF to 512 so we can be sure there is room for a
kernel core header before the message buffer.

Fix MSGBUFSIZE

Correct for the extra member in 'struct kern_msgbuf' when calculating
the number of bytes we want to allocate.

Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

branches: 1.43.2;
Restore the define of UPAGES.

Define NBSG from (1 << SEGSHIFT) and move some variables before
<m68k/param.h>.

Use the MI <m68k/param.h> include.

Define VM_MAX_KERNEL_ADDRESS using KERN_END instead of a constant.

Allow option MCLSHIFT=x to control MCLBYTES etc.

Use ALIGNBYTES in the new ALIGNED_POINTER macro.
(That is always good enough on the m68k.)

Define ALIGNED_POINTER

branches: 1.36.4;
Move sun3_btop (etc.) macros from param.h to pte.h

Define MAXBSIZE as 32KB to limit the size clustered transfers.

add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH,
execpt without quotes. meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).

Clean up tabbing/spacing in defns of MACHINE, MACHINE_ARCH, and MID_MACHINE.

Improved delay() implementation with lower overhead,
makes very short delays much more accurate.

LOCORE -> _LOCORE

Need to define KERNTEXTOFF for kvm_mkdb

branches: 1.29.2;
Nuke user-mode DELAY() macro.

clean up definitions of ctod(), dtoc(), ctob(), btoc(), btodb(), and
dbtob(). remove unused definitions of ctos(), stoc(), and dtob().

Provide delay2us as an inline and make it reasonably accurate,
but conservative (long) by a factor of about 1.25

KERNEL -> _KERNEL

Put spltty at level 4 and adjust others appropriately.
Also, improve the inline _spl() and move it to psl.h

don't be so quick to cast macro arguments to unsigned; if the
arguments are really off_t's (e.g. to btodb), then you can lose
information. This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.

cosmetic

Add USPACE

Lots of changes. Fairly stable now.

Remove some unnecessary junk.

new RCS ID format.

Kill CLOCK_VA, INTERREG_VA. Do spl0() and splx(x) inline too.

asm -> __asm (PR #463).

Add USPACE

Catch up with frame.h chages, merge stuff from new hp300 port.

Make the DELAY macro call the new delay() function.

ugh. splimp is the greater of splnet and splbio now. used by pmap module for splpmap()

boots, presents shell prompt, and doesn't crash immediately

MACHINE_ARCH

Now works with current tree, as opposed to the july 8th tree in which it was
written.
Requires magnum infrastructure now, particularly the clock stuff.
Fails to exec init because the /sbin/init binary
is a sunos binary. Next step is to integrate sunos compatibility code
from /sys/compat/sunos, and the amiga port.
Does not yet implement MACHINE_NOCONTIG support.

[from glass Mon Nov 22 21:22:45 PST 1993 home tag: home2]

sun3 port updated. netboot integrated.

last snapshot before uploading. we still have serious clock problems

snapshot. for uploading. gets lost in swtch after enablertclock()

various changes

gets to consinit() and blows up

it links with out any unresolved symbols, last few are just stubs
because we aren't likely to get near execing init for a while

whatever was necessary to make the rest of it work.

fixed bug in mon.h; fixed NEED_* in cpu.h; spl macro problems

adding include files...not much of this works
