Subject: [PATCH] Subject: [PATCH] remoteproc: clean up notification config

Rearrange the config files for remoteproc and IPA to fix their
interdependencies.

First, have CONFIG_QCOM_Q6V5_MSS select QCOM_Q6V5_IPA_NOTIFY so the
notification code is built regardless of whether IPA needs it.

Next, represent QCOM_IPA as being dependent on QCOM_Q6V5_MSS rather
than setting its value to match QCOM_Q6V5_COMMON (which is selected
by QCOM_Q6V5_MSS).

Drop all dependencies from QCOM_Q6V5_IPA_NOTIFY.  The notification
code will be built whenever QCOM_Q6V5_MSS is set, and it has no other
dependencies.

Dave,
    I noticed some problems with the interaction between the IPA and
    remoteproc configs, and after some discussion with Bjorn we came
    up with this, which simplifies things a bit.  Both Kconfig files
    are in net-next now, so I'm sending this to you.

    Two other things:
    - I will *not* be implementing the COMPILE_TEST suggestion until
      after the next merge window.
    - I learned of another issue that arises when ARM64 is built
      with PAGE_SIZE > 4096.  I intend to fix that in the next day
      or so.
