92891185c3 Don't need a prototype for pmap_bootstrap_alloc(); the function 
does not exist in the pmap API anymore.

69fd928d7c Remove pmap_kenter_pgs(). It was never really adopted by 
anything, and the interface itself wasn't as flexible as
callers would have probably liked.

7f10ba88b1 #define away pmap_update() in <machine/pmap.h> so that no function 
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).

15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.

* turn ad-hoc `pmap resources allocated during sleep' into a panic condition
  (this should all be prevented by higher level VM locking).
* arrange for ENOMEM to be returned if PMAP_CANFAIL is on, and malloc()
  and/or pool_get() fail.

cd24bc13e7 Account for the number of counter ticks that elapse while statintr() 
processing takes place. This prevents stat clock skew by a factor
approximately proportional to stathz (not a serious problem if stathz==100;
but considerable already if stathz==1000).

4de5b658ad Use a pool cache for pmap allocation. The cached pmap structures include

A simple `fork()' test shows an improvement in spent system time of
around 4 percent (which is just a bit disappointing, IMO, but it's
an improvement nonetheless).

20ba07f2fe - add dev_noimpl(xxx,yyy) macro to replace "(dev_type_xxx((*))) yyy", 
and use appropriately

- create more helper macros:
   . cdev__xyz_init(c,n), such as cdev__ocri_init() for
     /* open, close, read, ioctl */, etc.
   . cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
     method `R' and the comments now read /* xxx (read) yyy */ instead
   . cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
     as well

- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
  always DTRT WRT returning a valid result.  (a few devices previously
  incorrectly returned ENODEV)

- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
  == 0, because it doesn't matter if dev_type_stop isn't implemented in that
  case, and it allows the use of the cdev__xyz_init macros. certain ports
  (sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
  drivers, whereas everything else uses enodev

- ensure that the comments are accurate WRT the behaviour of a given entry

e533061fce in mem_access_fault*(), when invoking the pcb_onfault mechanism, pass the 
return value of uvm_fault() to the onfault routine via %o0.  users of
pcb_onfault now return this value to their callers rather than always
returning EFAULT. this allows i/o errors in VOP_GETPAGES() to be returned
back to read(), etc.
