From: Rob Herring <rob.herring@calxeda.com>

With the recent MULTI_IRQ_HANDLER support, many of the platform
entry-macro.S files can be removed. This series removes empty
isable_fiq and arch_ret_to_user macros from most platforms.

This leaves iop13xx, iop32x and iop33x with compile time difference
from other platforms.

changes in v2:
- Change CONFIG_ARCH_HAS_RET_TO_USER to CONFIG_NEED_RET_TO_USER
- Add runtime installed default fiq handler to RiscPC

Rob

Rob Herring (4):
  ARM: make arch_ret_to_user macro optional
  ARM: rpc: make default fiq handler run-time installed
  ARM: make entry-macro.S depend on !MULTI_IRQ_HANDLER
  ARM: remove empty disable_fiq and arch_ret_to_user macros

Only 3 platforms need arch_ret_to_user macro, so add NEED_RET_TO_USER
kconfig option and make iop13xx, iop32x and iop33x select it.

From: Rob Herring <rob.herring@calxeda.com>

Only rpc uses disable_fiq macro. Change it to a run-time installed
default FIQ handler. The handler is installed before interrupts are
enabled so the behavior should be unchanged.

Given that you want to get rid of disable_fiq, it would be a good idea 
to replace it with its content here.

* [PATCH v3] ARM: rpc: make default fiq handler run-time installed

From: Rob Herring <rob.herring@calxeda.com>

Only rpc uses disable_fiq macro. Change it to a run-time installed
default FIQ handler. The handler is installed before FIQ is enabled
so the behavior should be unchanged.

Nico,

This removes the use of disable_fiq now. To keep it bisectable, the macro
gets removed from entry-macro-iomd.S in the last patch now.

Do you need to include <mach/entry-macro.S> here?

With the removal of disable_fiq on rpc and addition MULTI_IRQ_HANDLER,
entry-macro.S is no longer needed for platforms that select
MULTI_IRQ_HANDLER and the include of it can be conditional.

Now that most platforms don't need disable_fiq and arch_ret_to_user
macros, we can remove the empty macros or empty entry-macro.S files.
