sys/arch/mips/mips/pmap.c: revision 1.222
sys/arch/mips/mips/pmap.c: revision 1.223
Fix a bug introduced by me in 1.214 where unmanaged mappings would be
affected by calls to pmap_page_protect which is wrong. Now PV_KENTER
mappings are left intact.
Thanks to chuq for spotting my mistake and reviewing this diff.
Thanks to everyone who tested it as well.
Fix PR/51288 reproducable panic on evbmips64-eb (erlite)
pmap_page_remove from the previous change neglected to terminate the pv
list correctly when it started with an initial unmanaged mapping and
subsequent managed mappings. Fix this.
Fix MIPS3_NO_PV_UNCACHED alias handling by looping through the pv_list
looking for bad aliases and removing the bad entries. That is, revert
to the code before the matt-mips64 merge.
Additionally, fix the pmap_update call to not use the (recently
removed/freed) pv for the pmap_t.
Fixes the following two PRs
PR/49903: Panic during installation on WorkPad Z50 (hpcmips) whilst uncompressing base.tgz
PR/51226: Install bug for hpcmips NetBSD V7 using FTP Full installation
