Subject[PATCH v2 3/3] powerpc/uaccess: Merge raw_copy_to_user_allowed() into raw_copy_to_user()
Date
Since commit 17bc43367fc2 ("powerpc/uaccess: Implement
unsafe_copy_to_user() as a simple loop"), raw_copy_to_user_allowed()
is only used by raw_copy_to_user().

Merge raw_copy_to_user_allowed() into raw_copy_to_user().
