Subject: [PATCH 072/117] ARM: 7365/1: drop unused parameter from
|
|
flush_cache_user_range

commit 4542b6a0fa6b48d9ae6b41c1efeb618b7a221b2a upstream.
|
|
|
|
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.
