[PATCH v2 1/4] arm64: use 'segment' rather than 'chunk' to describe mapped kernel regions

Replace the poorly defined term chunk with segment, which is a term that is
already used by the ELF spec to describe contiguous mappings with the same
permission attributes of statically allocated ranges of an executable.
