        crashkernel: optimize arm64 reserved size if PAGE_SIZE=4k
    
        On RHEL9 and Fedora, the arm64 platform only supports 4KB page size.
        the reserved memory size can be aligned to that on x86_64.
    
        Introducing a new formula for 4KB on arm64, which bases on x86_64 plus
        extra 64MB.
