Aneesh/Ben reported that the change to do_page_fault() needs to handle the case where CPU_FTR_COHERENT_ICACHE is missing but we have CPU_FTR_NOEXECUTE. In those cases the check added for SRR1_ISI_N_OR_G might trigger a false positive. This patch checks for CPU_FTR_COHERENT_ICACHE in addition to the MSR value Reported-by: Aneesh Kumar K.V <redacted> Signed-off-by: Balbir Singh <bsingharora@gmail.com>
