    Subject[PATCH 4.19 49/81] powerpc: Remove STRICT_KERNEL_RWX incompatibility with RELOCATABLE
    Date
    From: Russell Currey <ruscur@russell.cc>

    [ Upstream commit c55d7b5e64265fdca45c85b639013e770bde2d0e ]

    I have tested this with the Radix MMU and everything seems to work, and
    the previous patch for Hash seems to fix everything too.
    STRICT_KERNEL_RWX should still be disabled by default for now.

    Please test STRICT_KERNEL_RWX + RELOCATABLE!
