This addresses kern/10981 by Matthew Orgass.
- allow entry of the same mapping that's already there.
this can happen with UBC.
- if PMAP_CANFAIL, return failure rather than sleeping
when we fail to allocate a ptp.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.
pmap_enter() will get called trying to wire an already wired page again
if sysctl() is called. To avoid a panic the "wired" check is moved after
the double-mapping check.
Because of this kvtophys() of wired pages did set the leftmost bit, causing
the pager to hang while swapping. This is now fixed by using another
free bit in the PTE as wired bit instead.
This fixes PR#11121.
Many thanks to Chuck Silvers that found what the problem was!
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.
