    Subject[PATCH AUTOSEL for 3.18 35/59] powerpc/ipic: Fix status get and status clear
    Date
    From: Christophe Leroy <christophe.leroy@c-s.fr>

    [ Upstream commit 6b148a7ce72a7f87c81cbcde48af014abc0516a9 ]

    IPIC Status is provided by register IPIC_SERSR and not by IPIC_SERMR
    which is the mask register.
