These seem to be caused by 128ea04a9885 (lto: Make asmlinkage __visible,
2014-02-08). Before that change asmlinkage was defined to nothing on
ARM, but now it's __visible. Should we just drop asmlinkage here?

----8<----

From: Stephen Boyd <sboyd@codeaurora.org>
Subject: [PATCH] irqchip: Remove asmlinkage from static functions

LTO patches add __visible to the asmlinkage define, causing
compilation warnings like:

  drivers/irqchip/irq-gic.c:283:1: warning: 'externally_visible'
  attribute have effect only on public objects [-Wattributes]

Drop asmlinkage here to avoid such warnings.

These functions are just called by the generic C interrupt layer right?
Yes should just drop asmlinkage. It doesn't make any sense to mark
functions that only called from C asmlinkage.

Patch looks good to me.

On ARM[64], these functions are called from assembly indirectly through
the 'handle_arch_irq' function pointer, so I don't think it makes sense
to drop 'asmlinkage'.

If building with a C++ compiler:

	asmlinkage = extern "C"

	static asmlinkage = static extern "C"

That doesn't quite make much sense when you think about it - even with
the existing definition in current mainline kernels.

So do you do anything special in asmlinkage? If not it won't make
any difference for you.

As Russell elaborated, ARM doesn't have the special calling convention
magic that x86 does, so it should be safe to remove.

Sorry for the noise,

[PATCH] irqchip: Remove asmlinkage from static functions

[Stephen Boyd]

LTO patches add __visible to the asmlinkage define, causing
compilation warnings like:

  drivers/irqchip/irq-gic.c:283:1: warning: 'externally_visible'
  attribute have effect only on public objects [-Wattributes]

Drop asmlinkage here to avoid such warnings.

[PATCH] irqchip: Remove asmlinkage from static functions

[Stephen Boyd]

LTO patches add __visible to the asmlinkage define, causing
compilation warnings like:

  drivers/irqchip/irq-gic.c:283:1: warning: 'externally_visible'
  attribute have effect only on public objects [-Wattributes]

Drop asmlinkage here to avoid such warnings.

irqchip: Remove asmlinkage from static functions

LTO patches add __visible to the asmlinkage define, causing
compilation warnings like:

  drivers/irqchip/irq-gic.c:283:1: warning: 'externally_visible'
  attribute have effect only on public objects [-Wattributes]

Drop asmlinkage here to avoid such warnings.
