We are exploring how to enable kdump in an offical support way, which leads us to this page: https://docs.redhat.com/en/documentation/openshift_container_platform/4.14/html/support/troubleshooting#enabling-kdump-day-one

However it is quite mis-leading, that after reading the document, we are not sure:

Whether enable it via MachineConfig is a support way after cluster provisioned as day2 operation
How much memory is required, is 256M really enough? as in the doc, it only mention different size for ppc64le but not for other architecture, may we assume others should use 256M?
