thorpej 1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

lukem 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

thorpej 40c4d1e0c3 Rename the CLI/STI/ECLI/ESTI macros to more descriptive names, 
and add comments to describe exactly what they do (because it's
not totally obvious at a glance, due to the number juggling necessary
to frob the correct bits in SR):

CLI -> EXCEPT_DISABLE (sets SR.BL)
STI -> EXCEPT_ENABLE (clears SR.BL)

ECLI -> INTR_DISABLE (sets SR.I[0-3])
ESTI -> INTR_ENABLE (clears SR.I[0-3])

fvdl c7f1462f3e Add machdep file for procfs. Currently only used for linux-style 
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.

msaitoh d191cbf210 add interrupt mode into wdog 
To use:

	ioctl(fd, SIOWDOGSETMODE, &val)

	val:	WDOGM_RESET	-> reset when counter expired
		WDOGM_INTR	-> print PC when counter expired (new!)

This interface is still under experimental.
