bdbb241be6 Fix race between pmap_enter() and pagedaemon. If we are low on memory and 
pmap_enter() cannot allocate the segmap return failure if PMAP_CANFAIL
instead of sleeping.  Otherwise panic.  Both alpha and i386 do this.  Do
not pmap_enter_pv() until after this is done so the data structures are
not partially allocated.  This should prevent pmap_page_protect() from
getting stuck when called from pagedaemon.

3290ef5fe8 Re-order the TLB operations in pmap_zero_page() and 
pmap_zero_page_uncached().  This seems to prevent the
lossage with those functions people have seen on Cyrix
CPUs.

3f1d3c3066 tweak cpu_arch. Eliminate all direct checks of it (making them 
use the macro CPUISMIPS3 -- which is badly misnamed), and set it
from #defines named CPU_ARCH_N (where N is 1..5, 32, 64).

2fa1ccfa6e bootpath_build(): implement slighly more clever algorith to find boot 
flags in the bootpath: only treat the rest as boot flags if the '-'
follows whitespace (space or tab)

This should fix the "boot disk4 netbsd-20001004-RFHS8036" lossage
Hubert Feyer pointed out in private e-mail.

e9e1084ea3 rename mips_read_causereg -> mips_cp0_cause_read. nuke prototype 
for mips_read_statusreg (which was apparently never implemented).
Provide prototypes and implementations for mips_cp0_cause_write,
mips_cp0_status_read, and mips_cp0_status_write.  (Writing can, of
course, be quite dangerous.)

8b8afc8d07 the generic MIPS code doesn't even play at doing anything useful 
with a MIPS4 option at this point -- all the code except for one single
spot is conditionalized with MIPS3.  So, don't even pretend about
MIPS4 for now, until it all gets cleaned up.

8dbc5c0c51 provide mips3_ld() and mips3_sd(), functions which provide safe wrappers 
for mips3 (and later) 'ld' and 'sd' instructions.  These currently
only are properly implemented for the _MIPS_BSD_API_LP32 and
_MIPS_BSD_API_LP32_64CLEAN 'API's.  They're pretty messy, but when you
need them, you really need them.

2824f4906d Ensure all INSTALL* kernels have two ptys, and a note explaining why: 
pseudo-device  pty             2       # pseudo-terminals (Sysinst needs two)
(Some installers may not be using sysinst, in which case this just reduces
the number of ptys from 16 that are not used to 2 that are not used)
For i386 conf files, no change other than comments.
