3.2.92-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Christophe Leroy <christophe.le...@c-s.fr>
commit 8b8642af15ed14b9a7a34d3401afbcc274533e13 upstream.
Since commit 5093bb965a163 ("powerpc/QE: switch to the cpm_muram
implementation"), muram area is not part of immrbar mapping anymore
so immrbar_virt_to_phys() is not usable anymore.
Fixes: 5093bb965a163 ("powerpc/QE: switch to the cpm_muram implementation")
