#     powerpc/kexec_file: Count hot-pluggable memory in FDT estimate
#     
#     On Systems where online memory is lesser compared to max memory, the
#     kexec_file_load system call may fail to load the kdump kernel with the
#     below errors:
#     
#         "Failed to update fdt with linux,drconf-usable-memory property"
#         "Error setting up usable-memory property for kdump kernel"
#     
#     This happens because the size estimation for usable memory properties
#     for the kdump kernel's FDT is based on the online memory whereas the
#     usable memory properties include max memory. In short, the hot-pluggable
#     memory is not accounted for while estimating the size of the usable
#     memory properties.
#     
#     The issue is addressed by calculating usable memory property size using
#     max hotplug address instead of the last online memory address.
