Resolves: https://issues.redhat.com/browse/RHEL-77197 Upstream: kdump-utils Conflict: manually apply [Patch 2/2] The back port contains two upstream patches: 0d38985 powerpc: consider CPU count while calculating crashkernel value 4f7970e powerpc: Set nr_cpus=16 for kdump kernel to implement: Configure the kdump kernel with nr_cpus=16 to enable multi-threading in the makedumpfile core collector, allowing faster dump collection. The commit 4f7970e (powerpc: Set nr_cpus=16 for kdump kernel) can not be applied directly due to the big re-fractor of gen-kdump-sysconfig.sh. But the change is simple, just increase nr_cpus=1 to nr_cpus=16, so I modify it manually. Signed-off-by: Pingfan Liu <piliu@redhat.com>
