The kernel wants to enable reporting of asynchronous interrupts (i.e. System Errors) as early as possible. But if this happens too early then any pending System Error on initial entry into the kernel may never be reported where a user can see it. This situation will occur if the kernel is configured with CONFIG_PANIC_ON_OOPS set and (default or command line) enabled, in which case the kernel will panic as intended, however the associated logging messages indicating this failure condition will remain only in the kernel ring buffer and never be flushed out to the (not yet configured) console. Therefore, this patch moves the enabling of asynchronous interrupts during early setup to as early as reasonable, but after parsing any possible earlycon parameters setting up earlycon.
