sys/arm/iomd/iomd_irq.S has the similar code.
I think we should also fix it, but is there anyone
who try recent -crrent on acorn32?
If we fix both shark/isa/isa_irq.S and arm/iomd/iomd_irq.S,
no other source refers the spl_mask variable (except debug printfs).
Should we also remove it especially from arm/arm32/spl.S?

Overblocking might cause clock delays (if IPL_BIO interrupts
are handled at IPL_CLOCK), but it won't be fatal, I think.
