src/sys/arch/x86/x86: pmap.c
Log Message:
- Add more assertions.
- Range clipping for pmap_remove(): only need to keep track of the lowest VA
in PTP, as ptp->wire_count provides an upper bound. D'oh. Move set of
range to where there is already a writeback to the PTP.
- pmap_pp_remove(): panic if pmap_sync_pv() returns an error, because it means
something has gone very wrong. The PTE should not change here since the
pmap is locked.
- pmap_pp_clear_attrs(): wait for the competing V->P operation by acquiring
and releasing the pmap's lock, rather than busy looping.
- pmap_test_attrs(): this needs to wait for any competing operations,
otherwise it could return without all necessary updates reflected in
pp_attrs.
- pmap_enter(): fix cut-n-paste screwup in an error path for Xen.
