It was impossible to use directly 4.14 defconfig and apply it to 5.10.
Saving 4.14 in oldconfig, then editing in 5.10 was necessary.
- E1000E module (as kernel module support...) was lost in conversion and needed to be added back.
Also tuned things up:
- legacy-flash has no RETPOLINE, no security policy at all. Has expected usb controllers modules, exFAT and bare minimal support for flashrom.
- IMPORTANT: CONFIG_X86_IOPL_IOPERM kernel option is required by flashrom
- legacy adds sata, retpoline, additional modules (ethernet), security policy related material on top of legacy-flash config
- maximized adds MMC card support, mousedev+synaptic (to report presence through oem-system-info-xx30), thin provisioning+snapshot support
- tuned with linux.prompt_for_new_config_options_for_kernel_version_bump
Current storage format is oldconfig from now on for proper analysis. If needed, once can save back in defconfig prior of bumping to newer version.
