I sent a patch for it, Geert added an Ack, but it's still waiting to come
back through the renesas tree.

Note that the actual error is in arch/arm/mach-shmobile/platsmp.c,
not in pm-rcar-gen2.c

I reported the gcc but when it broke in 4.9, but it was only fixed in 6.1,
so this will have to wait for the kernelci infrastructure to do something
about it by updating their toolchain or blacklisting the config.

I though I sent a patch for it but con't find it now. We basically need
this:

This was the result of an incomplete merge conflict resolution in linux-next,
hopefully to be resolved soon.

I have to look into this.

I have not seen this one before, but it should be obvious, Kedareswara rao Appana
just submitted the new driver recently and can probably send a fix.

This showed up today, and I sent a patch.

I assume this is the result of using an older compiler, I haven't looked at the
details. Olof's build bot doesn't have it.

These are definitely coming from an older compiler, a couple of possible workarounds
have been sent in the past.

>       2  drivers/misc/mic/scif/scif_dma.c:118:27: warning: parameter 'ep' set but not used [-Wunused-but-set-parameter]

I also sent a patch for this on June 16, but I have some hope that
the maintainers still get to it.

I don't see any of these on ARM with gcc-6.1, I assume these are from older compilers,
or possibly architecture specific.

This was a side-effect of changes in the dynamic debug code to use
jump labels. I sent a patch to work around it in the driver, which
is not broken.

>       1  include/trace/events/devlink.h:16:467: warning: format '%lu' expects argument of type 'long unsigned int', but argument 10 has type 'size_t {aka unsigned int}' [-Wformat=]

I think my patch should be in tomorrow's linux-next.

Sent a patch a while ago.

I'll fix this later, it's harmless and is a result of a merge in linux-next.

We had some discussion about these, I think it's fixable but we don't have
a good patch yet (I suggested on that turned out to be bad).

I sent a patch on June 16 when this warning was only for "make W=1", but
never got a reply from the fbdev maintainers (which is not uncommon
for that subsystem). Now Andrew merged a patch to have the warning at the
default level, I'll send him my oneline patch so he can apply it as well:
