Probably a better description would be:

    RAS: ACPI: APEI: add conditional compilation to ARM error report functions
    
    Don't include ARM Processor specific error handling routines in 
    non-ARM platforms, preparing it to the next patch, as arm-specific
    kAPI symbols will be used, thus avoiding build breakages when ARM
    is not selected.

This patch itself just add conditionals to optimize out code on
non-ARM architectures. The next one will add some ARM-specific bits
inside ARM processor CPER trace, thus causing compilation breakages
on non-ARM, due to arm-specific kAPI bits that will be used then.

Thanks,
