For the problem under consideration we indeed want a compiler barrier because
the
error shows up due to a stale

Hi Vineet,
Just a short message to inform you that the test campaign on our RFC
patch has run through successfully and we consider the patch stable
enough for release to our customers. The main reason the barriers were
added in this particular place is because other architectures do the
same.

That's not a memory barrier, that a memory clobber, aka a compiler

This patch adds implicit memory barriers to irqsave/restore functions of
the ARC architecture port in line with what is done in other architectures.
It seems to fix several seemingly unrelated issues in our platform but for
the moment it is insufficiently tested (and might even be incomplete).
This patch adds implicit memory barriers to irqsave/restore functions of
the ARC architecture port in line with what is done in other architectures.
