Hi
I need to mask IRQ4 and interrupt on PC0. Does Linux do it at startup? does
the kernel is up with all interrupts masked?

Unless you register a device on that IRQ it will be thrown away as a bad
interrupt when your device starts generating random interrupts.
See register_irq and similar.
Cheers,
