    arm64: consistently log ESR and page table · 42dbf54e
    Mark Rutland authored
    When we take a fault we can't handle, we try to dump some relevant
    information, but we're not consistent about doing so.
    
    In do_mem_abort(), we log the full ESR, but don't dump a page table
    walk. In __do_kernel_fault, we dump an attempted decoding of the ESR
    (but not the ESR itself) along with a page table walk.
    
    Let's try to make things more consistent by dumping the full ESR in
    mem_abort_decode(), and having do_mem_abort dump a page table walk. The
    existing dump of the ESR in do_mem_abort() is rendered redundant, and
    removed.
