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'
arch/x86/crypto/sha1_ssse3_glue.c
arch/x86/crypto/sha256_ssse3_glue.c
arch/x86/crypto/sha512_ssse3_glue.c
drivers/irqchip/irq-armada-370-xp.c
drivers/irqchip/irq-bcm2835.c
drivers/irqchip/irq-gic.c
drivers/irqchip/irq-mmp.c
drivers/irqchip/irq-moxart.c
drivers/irqchip/irq-orion.c
drivers/irqchip/irq-sirfsoc.c
drivers/irqchip/irq-sun4i.c
drivers/irqchip/irq-vic.c
drivers/irqchip/irq-vt8500.c
drivers/irqchip/irq-zevio.c
drivers/pnp/pnpbios/bioscalls.c
scripts/checkpatch.pl

(the last two don't matter)
