Subject: [PATCH 0/5] arm64: assorted fixes for dcache_by_line_op

This fixes two issues in dcache_by_line_op: patch #4 fixes the logic
that is applied when patching DC CVAP instructions, and patch #5 gets
rid of some unintended undefined symbols resulting from incorrect use
of conditional GAS directives.

Patches #1 to #3 are groundwork for #4.
