[PATCH] PA-RISC irq handling improvements
- Move the bits_wide parameter from txn_alloc_data to txn_alloc_irq.
It's too late by the time it hits txn_alloc_data(), we can only panic.
In txn_alloc_irq, we can fail the allocation and continue.
- Also fix a bug where we'd only allow up to half the interrupts to be
allocated. Not a problem for iosapic machines, but might have sucked
on a really big GSC-based machine.
- Add missing irq_enter() / irq_exit()
- Allow interrupt processing to be interrupted by the timer tick so we
actually account hard interrupts. Also speed up the handling of CPU
interrupts by not masking with cpu_eiem again.
- Remove sufficiently obsolete DEBUG_IRQ code
- Remove limit on times around the loop. If we exit the loop while
interrupts are still pending, we'll only be re-interrupted as soon
as we exit the function.
- Remove unnecessary includes
