Subject: [PATCH v2 2/8] arm64: debug: Rename addr parameter for non-watchpoint exception hooks

From: Will Deacon <[email-masked]>
Date: Fri, 5 Apr 2019 13:40:42 +0100

Since the 'addr' parameter contains an UNKNOWN value for non-watchpoint
debug exceptions, rename it to 'unused' for those hooks so we don't get
tempted to use it in the future.
