Subject: [PATCH 1/6] powerpc/kvm: Clarify __user annotations
Date: Mon,  4 Jul 2016 17:09:37 +1000	[thread overview]
Message-ID: <1467616182-30886-1-git-send-email-dja@axtens.net> (raw)

kvmppc_h_put_tce_indirect labels a u64 pointer as __user. It also
labelled the u64 where get_user puts the result as __user. This isn't
a pointer and so doesn't need to be labelled __user.

Split the u64 value definition onto a new line to make it clear that
it doesn't get the annotation.
