kleines Filmröllchen d0e614c045 Kernel: Don't check that interrupts are enabled during early boot
The interrupts enabled check in the Kernel mutex is there so that we
don't lock mutexes within a spinlock, because mutexes reenable
interrupts and that will mess up the spinlock in more ways than one if
the thread moves processors. This check is guarded behind a debug flag
because it's too hard to fix all the problems at once, but we regressed
and weren't even getting to init stage 2 with it enabled. With this
commit, we get to stage 2 again. In early boot, there are no interrupts
enabled and spinlocks used, so we can sort of kind of safely ignore the
interrupt state. There might be a better solution with another boot
state flag that checks whether APs are up (because they have interrupts
enabled from the start) but that seems overkill.
