From: Ard Biesheuvel <ardb@xxxxxxxxxx> This is a follow-up to the patches sent out by Jonathan last week [0][1], to fix the broken command line handling in the EFI stub, which currently fails to use the built-on command line as a fallback as it never considers the bootloader provided command line to be empty. This series fixes some more identified issues: - free the correct pointer on error - parse the built-in command line *after* the bootloader provided one, if both are available, to match the core kernel's behavior - implement the missing fallback handling when loading files provided on the command line via initrd= or dtb= - ignore the bootloader provided command line when FORCE or OVERRIDE are configured The latter is provided as a separate change, as it changes behavior in a way that could result in regressions, however unlikely.
