Reprogramming takes places before putting the CPU into idle mode if
the dynamic tick option is enabled. The timer is then set to expire
at the next pending timer event. Because some time has already passed
since the last reported jiffy we have to wait less than the time
specified in jiffies.
Also make sure we don't set a load value of 0 whose outcome is
unspecified according to the TRM.

Patch from David Brownell
ARM genirq cleanups/updates:
- Start switching platforms to newer APIs
* use "irq_chip" name, not "irqchip"
* providing irq_chip.name
- Show irq_chip.name in /proc/interrupts, like on x86.
This update a bit more than half of the ARM code. The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

The GPIO IRQ mask was retrieved incorrectly in cases where we have a mask
register instead of an enable register. Also we should only return the
valid bits depending on the bank size.

delivered.

- The current OMAP GPIO IRQ framework doesn't use the do_edge_IRQ,
do_level_IRQ handlers, but instead calls do_simple_IRQ. This
doesn't handle disabled interrupts properly, so drivers will
still get interrupts after calling disable_irq. The patch solves
this by respecting the irq_desc.disable_depth and irq_desc.running
counters. When one of these is non-zero the handler is not called,
the interrupt is masked and marked as pending. The pending interrupt
will be serviced when the running handler returns. This is according
to the same semantics as the standard do_edge_IRQ and do_level_IRQ
handlers have, so one day we should use them instead of do_simple_IRQ.
- Process only interrupts that are not masked. The ISR may contain
pending interrupts that are masked these shouldn't be processed.
- Move the bank IRQ unmasking out of the IRQ dispatch loop. If there
are further iterations we shouldn't unmask it if there are level
triggered interrupts pending.
