Recently there has been some work in reporting and fixing bugs in booting an allmodconfig kernel - here are a few examples: https://lore.kernel.org/linux-edac/304df85b-8b56-b77e-1a11-aa23769f2e7c@xxxxxxxxxx/T/#t https://lore.kernel.org/linux-ide/bdf02e03-86a1-3d35-2908-28187f504495@xxxxxxxxxx/T/#t https://lore.kernel.org/netdev/CADYN=9LCPfbpwdTWKw03B22-y3Text=RWXW7XP7wJBHYsMOgrA@xxxxxxxxxxxxxx/ https://sourceforge.net/p/openipmi/mailman/message/36871567/ If we want to boot an allmodconfig kernel we may still want to force some loadable modules built-in, like UART drivers. Or just still turn off some configs. So add an option to add add fragments to an allmodconfig kernel.
