Hello,
This is resend of the last patch in the series that adds prefix support

This POC is a material for the discussion "Simplify Livepatch Callbacks,
Shadow Variables, and States handling" at LPC 2013, see
https://lpc.events/event/17/contributions/1541/
It obsoletes the patchset adding the garbage collection of shadow
variables. This new solution is based on ideas from Nic
The basic livepatch functionality is to redirect problematic functions
to a fixed or improved variants. In addition, there are two features
helping with more problematic situations:
+ pre_patch(), post_patch(), pre_unpatch(), post_unpatch() callbacks
might be called before and after the resp
The handling of the lifetime of the shadow variables is not easy
when the atomic replace is used. The new patch does not know
if a shadow variable has already been used by the previous livepatch.
Or if there is a shadow variable which will not longer be used.
Shadow variables are almost always use
Recent changes in the livepatch core have allowed to connect states,
shadow variables, and callbacks. Use these new features in
the state tests.
Use the shadow variable API to store the original loglevel. It is
better suited for this purpose than directly accessing the .data
pointer in state klp_s
The per-object callbacks have been obsoleted by per-state callbacks.
As a result, the callbacks test modules have been obsoleted
by updated klp state tests.
The callbacks test modules are re-used in the sysfs selftests.
It would be possible to replace them by klp state test modules
but the newly g
The original livepatch callbacks has been obsoleted by the livepatch
state callbacks.
The important difference is that the original callbacks were associated
with the livepatched object. The state callbacks are associated with
the livepatch states which are associated with the livepatch.
As a res
All selftests have been migrated to the new per-state callbacks.
And the obsoleted per-object callbacks can be safely removed.
FIXME:
This patch is removing the sample module and documentation
without any replacement. They obviously have to be converted
for the state-callbacks.
It has been postp
The livepatch state API was added to help with maintaining:
+ changes done by livepatch callbasks
+ lifetime of shadow variables
The original API was hard to use. Both objectives are better handled
by the new per-state callbacks. They are called when the state is
introduced or removed. Ther

It adds support to bring up remoteproc's on multipd model.
Pd means protection domain. It's similar to process in Linux.
Here QDSP6 processor runs each wifi radio functionality on a
separate process. One process can't access other process
resources, so this is termed as PD i.e protection domain.

In multipd model, root & user pd remoteproc's interrupts are
different. User pd needs additional interrupts like spawn.
Instead of going with qcom_q6v5_init(), we defined a new
function to register userpd rproc interrupts in mpd driver.
Since userpd rproc uses some of common interrupts like fatal,
APSS brings Q6 out of reset and then Q6 brings
WCSS block (wifi radio's) out of reset.
