From: Prarit Bhargava <prarit@xxxxxxxxxx>
The 'process_configs.sh -n -w -c' command on the fedora configs terminates with
Processing /home/prarit/git-kernel/kernel-ark/redhat/configs/kernel-5.8.0-aarch64-debug.config ... Error: Mismatches found in configuration files
Found CONFIG_FORCE_MAX_ZONEORDER=11 after generation, had CONFIG_FORCE_MAX_ZONEORDER=13 in Source tree
make: *** [Makefile:149: fedora-configs] Error 1
The fedora aarch64 CONFIG entry for CONFIG_FORCE_MAX_ZONEORDER notes that
the warning can only be fixed through an out-of-tree patch. Unfortunately
this means that the process_configs checkoptions check cannot be run on
fedora aarch64 configs.
To work around this problem, add a special tag
"process_configs_known_broken" which can be added as a comment to a known
broken CONFIG file. Adding the tag will result in process_configs
checkoptions skipping the CONFIG's error.
Add the process_configs_known_broken flag to process_config.sh and fix
'make fedora-configs' by adding process_configs_known_broken to
CONFIG_FORCE_MAX_ZONEORDER.
