Paul Gortmaker 9f3045eca8 irq: hide debug macros so they don't collide with others.
The file kernel/irq/debug.h temporarily defines P, PS, PD
and then undefines them.  However these names aren't really
"internal" enough, and collide with other more legit users
such as the ones in the xtensa arch, causing:

In file included from kernel/irq/internals.h:58:0,
                 from kernel/irq/irqdesc.c:18:
kernel/irq/debug.h:8:0: warning: "PS" redefined [enabled by default]
arch/xtensa/include/asm/regs.h:59:0: note: this is the location of the previous definition

Add a handful of underscores to do a better job of hiding these
temporary macros.

Paul Mundt 7f1b1244e1 genirq: Support per-IRQ thread disabling.
This adds support for disabling threading on a per-IRQ basis via the IRQ
status instead of the IRQ flow, which is necessary for interrupts that
don't follow the natural IRQ flow channels, such as those that are
virtually created.

The new APIs added are simply:

	irq_set_thread()
	irq_set_nothread()

which follow the rest of the IRQ status routines.

Chained handlers also have IRQ_NOTHREAD set on them automatically, making
the lack of threading explicit rather than implicit. Subsequently, the
nothread flag can be viewed through the standard genirq debugging
facilities.

Thomas Gleixner 32f4125ebf genirq: Move INPROGRESS, MASKED and DISABLED state flags to irq_data
We really need these flags for some of the interrupt chips. Move it
from internal state to irq_data and provide proper accessors.

Thomas Gleixner 1ce6068dac genirq: Move debug code to separate header
It'll break when I'm going to undefine the constants.
