Greg upon trying to boot no-MMU Kernel on ARM926EJ reported boot failure. He root caused it to ID_PFR1 access introduced by the commit mentioned in the fixes tag below. All CP15 processors need not have processor feature registers, only for architectures defined by CPUID scheme would have it. Hence check for it before accessing processor feature register, ID_PFR1. Fixes: f8300a0b ("ARM: 8647/2: nommu: dynamic exception base address setting") Reported-by:
