| |
3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dima Zavin <dima@android.com>
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.
