Subject: linux-next: build warning after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/irqchip/irq-armada-370-xp.c:415:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
drivers/irqchip/irq-sun4i.c:39:70: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
drivers/irqchip/irq-sun4i.c:140:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
drivers/irqchip/irq-gic.c:283:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
drivers/irqchip/irq-sirfsoc.c:51:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]
drivers/irqchip/irq-vt8500.c:183:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes]

Probably introduced by commit 128ea04a9885 ("lto: Make asmlinkage __visible").

I guess that there may be more places where "asmlinkage" is used with
"static" - I assume that they are all incorrect?

$ git grep -l 'static.*asmlinkage'

(the last two don't matter)
