Modified Files:
src/sys/arch/x86/x86: pmap.c
Log Message:
- Make pmap_write_protect() work with pmap_kernel() too ((va & L2_FRAME)
strips the high bits of a LP64 address)
- use pmap_protect() in pmap_pdp_ctor() to remap the PDP read-only instead
of (ab)using pmap_kenter_pa(). No more "mapping already present" on
console with DIAGNOSTIC kernels
- make sure to zero the whole PDP (NTOPLEVEL_PDES doens't include
high-level entries on i386 and i386PAE, reserved by Xen). Not sure
how it has worked before
- remove an always-true test (&& pmap != pmap_kernel(); we KASSERT that
at the function entry).
