riastradh | Break cycle by using `struct kmutex *' instead of `kmutex_t *'.
sys/sched.h included sys/mutex.h
which includes sys/intr.h
which includes machine/intr.h
which on cats includes arm/footbridge/footbridge_intr.h
which includes arm/cpu.h
which includes sys/cpu_data.h
which includes sys/sched.h
But there was never any real need for sys/mutex.h in sys/sched.h,
because it only uses pointers to the opaque struct kmutex. Cycle
broken by using `struct kmutex *' instead of pulling in sys/mutex.h
for the definition of kmutex_t.
Side effect: This revealed that sys/cpu_data.h needed sys/intr.h
(which was pulled in accidentally by sys/mutex.h via sys/sched.h) for
SOFTINT_COUNT. Also revealed some other machine/cpu.h header files
were missing includes of sys/mutex.h for kmutex_t.

Improved the performance of kernel profiling on MULTIPROCESSOR, and possible to get profiling data for each CPU.
In the current implementation, locks are acquired at the entrance of the mcount
internal function, so the higher the number of cores, the more lock conflict
occurs, making profiling performance in a MULTIPROCESSOR environment unusable
and slow. Profiling buffers has been changed to be reserved for each CPU,
improving profiling performance in MP by several to several dozen times.
- Eliminated cpu_simple_lock in mcount internal function, using per-CPU buffers.
- Add ci_gmon member to struct cpu_info of each MP arch.
- Add kern.profiling.percpu node in sysctl tree.
- Add new -c <cpuid> option to kgmon(8) to specify the cpuid, like openbsd.
For compatibility, if the -c option is not specified, the entire system can be
operated as before, and the -p option will get the total profiling data for
all CPUs.

implement cpuctl identify for sparc and sparc64.
sparc:
- move enum vactype and struct cacheinfo into cpu.h
- move the cache flags from cpuinfo.flags into CACHEINFO.c_flags
(this allows the new cache_printf_backend() to see them.)
remove unused CPUFLG_CACHEIOMMUTABLES and CPUFLG_CACHEDVMA.
- align xmpsg to 64 bytes
- move cache_print() into cache_print.h so it can be shared with
cpuctl. it only depends upon a working printf().
- if found, store the CPU node's "name" into cpu_longname. this
changes the default output to show the local CPU not the
generic CPU family. eg:
cpu0 at mainbus0: mid 8: Ross,RT625 @ 90 MHz, on-chip FPU
vs the generic "RT620/625" previously shown.
- for each CPU export these things:
- name
- fpuname
- mid
- cloc
- freq
- psr impl and version
- mmu impl, version, and number of contexts
- cacheinfo structure (which changed for the first time ever
with this commit.)
sparc64:
- add a minimal "cacheinfo" structure to export the i/d/e-cache
size and linesize.
- store %ver, cpu node "name" and cacheinfo in cpu_info.
- set cpu_info ver, name and cacheinfo in cpu_attach(), and
export them via sysctl, as well as CPU ID and clock freq
cpuctl:
- add identifycpu_bind() that returns false on !x86 as their
identify routines do not need to run on a particular CPU to
obtain its information, and use it to avoid trying to set
affinity when not needed.
- add sparc and sparc64 cpu identify support using the newly
exported values.

macallan | - return early in xcall() if the function is sparc_noop() instead of triggering
the IPI and then ignoring responses ( or lack thereof )
- write the .tag field last to avoid a race when polling for an incoming
IPI
- add event counters for IPIs being caught with the mutex not held, and for
messages that are already marked as completed
With this my SS20 made it through 48 hours of pkgsrc with MAKE_JOBS=3 and a
pair of SM81s.
Hypersparcs still crash but instead of craziness we get actual error messages,
apparently one CPU will occasionally do a watchdog reset, which according to
the manual is caused by catching a trap with traps disabled. Now to figure
out how that can even happen...

Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

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.
g/c now unneeded routines and variables, including the reaper kernel thread

The boot CPU's existed only a CPUINFO_VA.
- Add a self-reference pointer to the cpu_info that references the

the `local' VA in the single-processor case, as CPUINFO_VA is global
enough when there's only one processor to care about. Change curcpu()

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.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".
"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

- fix a panic in savefpstate. idea, and code suggestions from uwe
- convert xpmsg_lock to IPL_SCHED. the old spl/simple_lock code ran at
splsched(), and this significantly helps with stability under load when
running with multiple active CPUs
- in strayintr() don't print about stray zs inters in MP case
- fix a deadlock in xcall()
- consolidate the interrupt evcnt(9) into a full set of per-IPL per-CPU
soft/hard counters
- fix xcall() failure messages in some cases
- addd new ddb command "mach xcall"
- use schedintr() (not schedintr_4m()) on MP or single CPU configurations
- call hardclock() the same way on cpu0 in MP and !MP cases
- request the appropriate stack space for nmi_sun4m, in particular,
make sure we have space for %g2...%g5. now entering ddb via eg,
serial break no longer causes cpu1 to fault.
- give memfault_sun*() some entry points that both gdb and ddb will find.
from tsutsui:
- fix panic in interrupt handlers in zs

- return early in xcall() if the function is sparc_noop() instead of triggering
the IPI and then ignoring responses ( or lack thereof )
- write the .tag field last to avoid a race when polling for an incoming
IPI
- add event counters for IPIs being caught with the mutex not held, and for
messages that are already marked as completed
With this my SS20 made it through 48 hours of pkgsrc with MAKE_JOBS=3 and a
pair of SM81s.
Hypersparcs still crash but instead of craziness we get actual error messages,
apparently one CPU will occasionally do a watchdog reset, which according to
the manual is caused by catching a trap with traps disabled. Now to figure
out how that can even happen...

sys/rwlock.h: Make this more self-contained for bool.
machine/mutex.h: Sprinkle includes so this can be used by crash(8).
ddb: New `show all tstiles' command.
Shows who's waiting for which locks and what the owner is up to.
Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE
sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>.
And thus out of <sys/param.h>, which is exceedingly overused and
fragile and delenda est.
Should fix (some) issues with the recent inclusion of machine/lock.h
in various machine/mutex.h files.
arm/mutex.h: Need machine/intr.h, machine/lock.h.
For ipl_cookie_t and __cpu_simple_lock_t.
evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL.
Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which
should really be fixed.
opencrypto/cryptodev.h: Fix includes.
- Move sys/condvar.h under #ifdef _KERNEL.
- Add some other necessary includes and forward declarations.
- Sort.
hp300/intr.h: Fix missing includes.
linux/idr.h: Need <sys/mutex.h> for kmutex_t.
amiga/intr.h: Don't define spl*() functions if !_KERNEL.
This is used by crash(8) now, and what's important is ipl_cookie_t.
cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8).
cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER.
Probably not necessary but let's be a little more cautious about
this.
atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8).
arm/cpu.h: Need sys/param.h for COHERENCY_UNIT.
Nix machine/param.h -- not meant to be used directly, pulled in by
sys/param.h.
Move the definition of ipl_cookie_t out of the kernel-only sections,
some _KMEMUSER applications need it.
ddb: Cast pointer to uintptr_t first before db_expr_t.
hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
news68k/intr.h: Fix includes. Put some definitions under _KERNEL.
next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
sys/ksem.h: Hack around fstat(8) abuse of _KERNEL.
sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
x68k/intr.h: Put functions under _KERNEL so crash(8) can use this.
Make ipl_cookie_t visible for _KMEMUSER userland applications.
fix editor mishap in previous
Explicitly include <sys/mutex.h> for kmutex_t.
Replace kmutex_t * (which may be undefined here) with struct kmutex *,
suggested by Taylor.
hp300/intr.h: Put most of this under #ifdef _KERNEL.
Only ipl_cookie_t really needs to be exposed now, for crash(8).
mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
Make inclusion of sys/intr.h explicit for spl*.
fix hppa and vax builds.
machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in
sys/types.h. avoids cpu_data.h vs sched.h include order issues.
move the hppa ipl_t typedef with the moved usage of it.
machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h.
Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which
always comes from sys/types.h. And, really, sys/types.h (or at least
sys/stdint.h) is needed for uintN_t and uintptr_t.
ddb: Cast pointer to uintptr_t, then to db_expr_t.
Avoids warnings about conversion between pointer and integer of
different size on some architectures.
re-fix hppa builds.
this file uses __cpu_simple_lock(), not just the underlying type,
so it does need machine/lock.h.
Break cycle by using `struct kmutex *' instead of `kmutex_t *'.
sys/sched.h included sys/mutex.h
which includes sys/intr.h
which includes machine/intr.h
which on cats includes arm/footbridge/footbridge_intr.h
which includes arm/cpu.h
which includes sys/cpu_data.h
which includes sys/sched.h
But there was never any real need for sys/mutex.h in sys/sched.h,
because it only uses pointers to the opaque struct kmutex. Cycle
broken by using `struct kmutex *' instead of pulling in sys/mutex.h
for the definition of kmutex_t.
Side effect: This revealed that sys/cpu_data.h needed sys/intr.h
(which was pulled in accidentally by sys/mutex.h via sys/sched.h) for
SOFTINT_COUNT. Also revealed some other machine/cpu.h header files
were missing includes of sys/mutex.h for kmutex_t.
ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t.
explicitly include no longer implicitly included sys/mutex.h.
arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz.
Sidesteps namespace collision with `#define bits ...' in net/zlib.c.
complete the previous - there were two calls to find_first_bit() to fix.
arm/xscale: Missed a spot with previous find_first_bit commit.
evbarm/g42xxeb: Fix off-by-one in previous.
The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x),
which is equivalent to fls32(x) - 1, not to fls32(x).
Note that fls32 is 1-based and returns 0 for x=0.
