[PARISC] timer interrupt should not be IRQ_DISABLED
Kyle McMartin [Wed, 28 Nov 2007 07:17:53 +0000 (02:17 -0500)]
The timer interrupt had accidentally been marked IRQ_DISABLED since
IRQ_PER_CPU had been OR-ed in, instead of set. This had been working
by accident for quite a while.

Commit c642b8391cf8efc3622cc97329a0f46e7cbb70b8 changed the behaviour of
IRQ_PER_CPU interrupts, which previously weren't checked for IRQ_DISABLED.
