f7cf6d4afb Do not try to second-guess the ncr53c9x driver by setting *dmasize to 0
if it is 64k.  TCL and TCM will be set properly if we just leave it alone.
Not only that, the ncr53c9x driver issues TRPAD or TRANS based on this
value.  We do not want TRPAD in this case!

811d597c78 Rework the esp driver a little bit to improve performance. This requires
an ugly bit where we record the value of a2 while handling a "nofault" bus
error in locore.s in order to know how far the transaction got before a
disconnect (see esp.c comments for more details on this).
Also get rid of a loop (and delay()!) in the interrupt routine--hinted at
and researched by Chas Williams <chas@cmf.nrl.navy.mil>.

851de295eb Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

c481cdca92 Overhaul of data-abort handling:
- Make data_abort_address() return the whole affected range, rather than
   just one end.
 - Don't rely on pmap_confess().  Instead, for LDM/STM, behave as if two faults
   had occurred, one at each end of the range.
 - Separate out fault handling into do_fault(), and call it from
   data_abort_handler() (twice) and prefetch_abort_handler().

58e80f030f Two batches of changes:
1: Cleanup of syscall() -- treat the arguments as an array of register_t
   throughout.  This saves a few casts, and generally makes seeing what's
   going on easier.
2: Be a little more careful in the handling of data aborts on kernel
   addresses: don't use the kernel's map unless the access was actually from
   a kernel mode.  This is how the arm32 data abort handler behaves.

2433e71e6e Medium-sized pmap overhaul:
- Use UVMHIST for debugging messages, rather than printf
 - Rely on the caller of pmap_enter to tell us how to manipulate referenced/
   modified bits in the kernel pmap.
   [ Suggested by chs -- may need work on the rest of the kernel. ]
 - Split third-stage initialisation out of pmap_create() into pmap_init2().
 - Bug fix: when relocating pv_table, fix up all references to it as well.
 - Bug fix: in pv_release(), if pulling up a pv_entry to the head of the
   list, correct the reference from its pmap.

- new CONFIG_HOOK_EVENT and CONFIG_HOOK_GET and CONFIG_HOOK_SET always have
  msg argument as pointer.
- new CONFIG_HOOK_EVENT and CONFIG_HOOK_GET and CONFIG_HOOK_SET use
  same event ids.
- CONFIG_HOOK_POWERCONTROL and CONFIG_HOOK_BUTTONEVENT still exist.
  i shall rewite codes by using new CONFIG_HOOK_SET and CONFIG_HOOK_EVENT.

ce3cd11d08 Unreasonably simple fix for PR#11817: Don't worry about duplicate mappings,
just get pmap_fault to shove them back in.  Crude, but effective.  Fix inspired
by Chuck Silvers.

This breaks pmap_confess, but it probably deserves to die.
