#     powerpc/fadump: when fadump is supported register the fadump sysfs files.
#     
#     Currently it is not possible to distinguish the case when fadump is
#     supported by firmware and disabled in kernel and completely unsupported
#     using the kernel sysfs interface. User can investigate the devicetree
#     but it is more reasonable to provide sysfs files in case we get some
#     fadumpv2 in the future.
#     
#     With this patch sysfs files are available whenever fadump is supported
#     by firmware.
#     
#     There is duplicate message about lack of support by firmware in
#     fadump_reserve_mem and setup_fadump. Remove the duplicate message in
#     setup_fadump.
