* move all device-specific bitbanging to the device drivers in question --
i.e., the ip32 init code doesn't access the CRIME registers directly but
instead trusts the CRIME driver to DTRT. machdep.c is cleaner thereby.
* introduce int.c, which handles the interrupt-controller goo formerly
in ip2x.c.
* unify the CPU interrupt handler, with CRIME, INT2, and the various timer
handlers hooked in via pointers in the platform struct.
* eliminate ip2x.c and ip32.c. After the interrupt handler cleanup, the
actual platform-dependent code was so minimal (rev identification, mask level
initialization) that it made sense to move it into machdep.c
* "#ifdef DEBUG printf("foo"); #endif" becomes aprint_debug.
Tested on my ip22 and ip32. Discussed with pooka@, rafal@.
Remove the vestigal sysbeep device and replace it with the same kind of

Many thanks to Paul Kranenburg for hints on a similar problem he fixed
for the sparc port.
- delete ktrsyscall32()
- add a check #ifdef _LP64 to do the conversion if P_32 is set to the
standard ktrsyscall()
- add a couple of similar _LP64/P_32 checks to the systrace code.
this should get systrace working for 32 bit apps as well as complete
ktrace support for "trace_enter/trace_exit" using platforms such as amd64.
XXX: systrace isn't supported on sparc64 currently... (it doesn't use
trace_enter/trace_exit, or have it's own calls to systrace_xxx()...)
files for machines I know to have genuine PCI slots. As sent to tech-kern
for feedback in December 2003. Based on feedback, opencrypto is commented
out in the macppc GENERIC (due to absense of GENERIC_SOFTINT support),
and added to the sparc64 config (sys/arch/sparc64/conf/GENERIC32).
The recommended workaround is a 5-10ms delay before and after accesses.
Therefore, move the affected bus_space_* operations from bus.h to bus.c
and special-case MACE accesses.
CRIME accesses are not affected, so introduce SGIMIPS_BUS_SPACE_CRIME and
use it as the CRIME tag.
My ip32 seems a little bit happier with this change, and my ip22 didn't
notice the change.
8-bit VIDC audio. Both Richard Earnshaw and I had guessed that a set
bit was positive (the same as normal mu-law), but the AudioWorks
manual, and Sound_SoundLog on RISC OS, seem to disagree. Change
MULAW_TO_VIDC to match Sound_SoundLog, since the latter is probably
definitive.
this usually isn't necessary since we freed it earlier in pmap_remove_all(),
but since uvmspace_free() is now called in the context of the exiting
process, a new context might be allocated if uvm_unmap_detach() decides
to sleep (since cpu_switch() will allocate a new context when it switches
back to the exiting process).
This makes it possible to define header files on the command line that
might include ${MACHINE} somewhere in the path. This might be used in
evbppc, for example, when defining PPC_PCI_MACHDEP_IMPL as, for example:
PPC_PCI_MACHDEP_IMPL="<arch/evbppc/sandpoint/pci_machdep.h>"
which will be included as
#include PPC_PCI_MACHDEP_IMPL
Prior to this change, the compile would fail trying to include
<arch/evbppc/1/pci_machdep.h>

note that this TLB bit is ignored on some CPUs (PA7100 and probably
others of that era), so this doesn't fix the problem in general,
but it does work on newer models and will make things easier later.

This saves couple cycles on the exit path.
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.

libpthread increments the sasi_stackgen counter in struct

- add struct sa_stackinfo_t with sasi_stackgen to count stack use in
userland
- add sast_gen to struct sastack to count stack use in kernel
- add SA_FLAG_STACKINFO to enable the stackinfo_offset argument in the
sa_register syscall
- add sa_stackinfo_offset to struct sadata for offset between ss_sp
and struct sa_stackinfo_t
- add ssize_t stackinfo_offset argument to sa_register, initialize
struct sadata's sa_stackinfo_offset from it if SA_FLAG_STACKINFO is
set
- add sa_getstack, sa_getstack0, sa_stackused and sa_setstackfree
functions to find/use/free upcall stacks and use these where
appropriate
- don't record stack for upcall in sa_upcall0
- pass sau to sa_switchcall instead of l2 (l2 = curlwp in sa_switchcall)
- add sa_vp_blocker to struct sadata to pass recently blocked lwp to
sa_switchcall
- delay finding a stack for blocked upcalls to sa_switchcall
- add sa_stacknext to struct sadata pointing to next most likely free

- add L_SA_WOKEN flag: LWP is on sa_woken queue
- add L_SA_RECYCLE flag: LWP should be recycled in sa_setwoken
- replace l_upcallstack with L_SA_WOKEN/L_SA_RECYCLE/L_SA_BLOCKING

- g/c now unused sast_blocker in struct sastack
- make sa_switchcall, sa_upcall0 and sa_upcall_getstate static in
kern_sa.c
- call sa_upcall_userret only once in userret
- split sa_makeupcalls out of sa_upcall_userret and use to process
the sa_upcalls queue
- on process exit: mark LWPs sleeping in saunblock interruptible; also
there are no LWPs sleeping on l->l_upcallstack anymore; also clear
sa_wokenq_head to prevent unblocked upcalls
additional changes:

virtual memory reservation and a private pool of memory pages -- by a scheme
based on memory pools.
This allows better utilization of memory because buffers can now be allocated
with a granularity finer than the system's native page size (useful for
filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation
of virtual to physical memory mappings (due to the former fixed virtual
address reservation) resulting in better utilization of MMU resources on some
platforms. Finally, the scheme is more flexible by allowing run-time decisions
on the amount of memory to be used for buffers.
On the other hand, the effectiveness of the LRU queue for buffer recycling
may be somewhat reduced compared to the traditional method since, due to the
nature of the pool based memory allocation, the actual least recently used
buffer may release its memory to a pool different from the one needed by a
newly allocated buffer. However, this effect will kick in only if the
system is under memory pressure.
- nothing needs to be done if ci_want_resched is already set.
- if the cpu isn't running any lwp, send a no-op ipi to it
so that it can resume immediately from halting in idle loop
without having to wait until the next clock tick.

- hpc1_hdd_{ctl,bufptr} and hpc3_hdd_{ctl,bufptr} are
established in hpcreg.h. All references to these fields
are updated with the exception of if_sq: (haltwo,
hpcdma). This makes reading the code and spotting bugs
easier.
- hpcdma.c was applying EOCHAIN to the wrong descriptor
word for the hpc1 case.
- I added scsi_max_xfer to the abstraction layer, and it
allows some crusty #defines in wdsc.c to be removed.
hpc1 now doesn't waste descriptors as it once did.
- hpcreg.h was updated to reflect the lack of XMITDONE

- hpc.c now verifies HPC1 revisions (1.0 vs 1.5) and
prints the output a little prettier ;)

exactly twice by me) which causes the code at the top of copyin which
word-aligns the destination pointer to copy more bytes than necessary,
resulting in an alignment fault later on.
The bug is difficult to reproduce, but as far as I can tell it seems
to be as a result of the condition codes being corrupted, possibly
following a page fault caused by the first ldrbt/strb instructions.
The subsequent ldr<cc>bt/str<cc>b instructions then _always_ execute.
I can't think of any obvious reason why this would happen, though.

While here, two more cosmetics:
- remove redundant definitions
- use NOMAN rather than setting MAN empty

a dedicated IOC driver that attaches its peripherals as children, but the
