e will simply fall back to using 'cur_cpu_spec'. The earlier defines for 'RADIX_MMU' have been renamed to 'MMU_TYPE_RADIX' which avoids conflict with the vmcoreinfo string 'RADIX_MMU', as well as being more clear about the value 0x40 with a comment about MMU_FTR_TYPE_RADIX Signed-off-by:

Re: [PATCH] makedumpfile: ppc64: do page traversal if vmemmap_list not populated

Or, the vmlinux can be provided to makedumpfile, so that it finds the 'cur_cpu_spec.mmu_features' symbol, run makedumpfile with '-x' flag similar to this: makedumpfile -l -d 31 -x VMLINUX /proc/vmcore /var/crash/vmcore.kdump Thanks, Aditya Gupta ___ kexec mailing
