ARM: 7365/1: drop unused parameter from flush_cache_user_range (4542b6a0) · Commits · 戴 / test

vma isn't used and flush_cache_user_range isn't a standard macro that is used on several archs with the same prototype. In fact only unicore32 has a macro with the same name (with an identical implementation and no in-tree users). This is a part of a patch proposed by Dima Zavin (with Message-id: 1272439931-12795-1-git-send-email-dima@android.com) that didn't get accepted. Cc: Dima Zavin <dima@android.com> Acked-by:
