Levente Kurusa 82242d28ff MIPS: IP22: Add missing put_device call
This is required so that we give up the last reference to the device.

Also, create a gio_bus_release() that calls kfree on the device argument to
properly kfree() the memory allocated for the device.

[ralf@linux-mips.org: Reformat to Linux coding style and make
gio_bus_release static.]

Yong Zhang 8b5690f884 MIPS: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled and we even check
and yell when an interrupt handler returns with interrupts enabled (see
commit [b738a50a: genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

Yury Polyanskiy ce384d83d0 MIPS: die() does not call die notifier chain
The MIPS implementation of die() forgets to call notify_die() and thus notifiers
registered via register_die_notifier() are not called.  This results in kgdb not
being activated on exceptions.

The only subtlety is that notify_die declares its regs argument w/o const, so
the const had to be removed from mips die() as well.

Mike Travis d2287f5ebe irq: update all arches for new irq_desc, fix
Impact: fix build errors

Since the SPARSE IRQS changes redefined how the kstat irqs are
organized, arch's must use the new accessor function:

	kstat_incr_irqs_this_cpu(irq, DESC);

If CONFIG_SPARSE_IRQS is set, then DESC is a pointer to the
irq_desc which has a pointer to the kstat_irqs.  If not, then
the .irqs field of struct kernel_stat is used instead.

Ralf Baechle 90b02340dc [MIPS] Switch from to_tm to rtc_time_to_tm
This replaces the MIPS-specific to_tm function with the generic
rtc_time_to_tm function.  The big difference between the two functions is
that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of
rtc_time_to_tm needs to be fixed up.
