[PATCH] i386: PARAVIRT: drop unused ptep_get_and_clear
In shadow mode hypervisors, ptep_get_and_clear achieves the desired
purpose of keeping the shadows in sync by issuing a native_get_and_clear,
followed by a call to pte_update, which indicates the PTE has been
modified.
Direct mode hypervisors (Xen) have no need for this anyway, and will trap
the update using writable pagetables.
This means no hypervisor makes use of ptep_get_and_clear; there is no
reason to have it in the paravirt-ops structure. Change confusing
terminology about raw vs. native functions into consistent use of
native_pte_xxx for operations which do not invoke paravirt-ops.
