arm64 pmap: Make VM_PAGE_TO_PV_LIST_LOCK() a constant-time operation
The prior implementation of VM_PAGE_TO_PV_LIST_LOCK() performed a

PHYS_TO_PV_LIST_LOCK(), that search is unnecessary because every (non-

namei: Add the abilty for the ABI to specify an alternate root path
For now a non-native ABI (i.e., Linux) uses the kern_alternate_path()
facility to dynamically reroot lookups. First, an attempt is made to
lookup the file in /compat/linux/original-path. If that fails, the
lookup is done in /original-path. Thats requires a bit of code in
every ABI syscall implementation where path name translation is needed.
Also our kern_alternate_path() does not properly lookups absolute symlinks
in second attempt, i.e., does not append /compat/linux part to the resolved
link.
The change is intended to avoid this by specifiyng the ABI root directory
for namei(), using one call to pwd_altroot() during exec-time into the ABI.
In that case namei() will dynamically reroot lookups as mentioned above.
