matt 8402e4d93f Fix a missing restore interrupt. disable interrupts around pvo_enter in
pmap_kenter.  Shouldn't be needed but ...

matt 04bdd02c1a Make pmap_pte_insert STATIC so it will show up in DEBUG kernel with DDB
traces.
2001-08-30 22:06:44 +00:00
matt 4a580ee45e Make sure to restore SR 0 since returning from a syscall is actually
one way of doing a process context switch.

chs ea127ad258 use pmap_k* in pagemove(), ie. for buffer cache pages.
in vunmapbuf(), call pmap_kremove() explicitly since uvm_km_free_wakeup()
will soon no longer do it for us.

matt 39fa08a172 Reset segment registers 1-7 upon entry to kernel (via trap or interrupts)
so that the bat spill code won't run into spurious valid user pages and
treat them as kernel pages.  Restore segment registers 1-7 upon return to
user mode from either a trap or interrupt.   XXX  eventually do all 16 SRs

matt 7c5977ea4f Fix a spurious debug printf.
Fix pmap_procwr to not check a NULL pvo.  (Duh!)
