Thanks very much for your review on this.
BTW: Since 3.15 merge window is still open, I am wondering whether there is
any possibility to make SMAP into 3.15 with another pull request.
This is up to Marcelo who is currently managing the KVM tree.

The merge window is for patches which have been tested in queue/next
for sometime. This patch has received no testing other than the
developer testing.
This is not going to change unfortunately since this is not shipping in
any real silicon. The only hope could be to use QEMU's SVM and SMAP
emulation.
Lack of implicit supervisor mode by instructions such as "Examples of
such implicit..." in section 9.3.2, in KVM's emulator, makes the feature
incomplete, does it not ?
Implicit supervisor mode is handled by KVM emulator using
read/write_std. These accesses do not set PFERR_USER_MASK, and should
work fine with SMAP. Am I misunderstanding?

(would have to signal those accesses as supervisor ones).
