Subject[PATCH RFC] ia64: export ia64_delay_loop for "allmodconfig" coverage
Date
Currently we see:

ERROR: "ia64_delay_loop" [drivers/spi/spi-thunderx.ko] undefined!
ERROR: "ia64_delay_loop" [drivers/net/phy/mdio-cavium.ko] undefined!

...on ia64 allmodconfig builds. While it is true nobody would ever
load/use these !ia64 drivers on ia64 kit, they probably won't be the
only ones enabled via COMPILE_TEST or non-strict dependencies as time
goes on. So just export the symbol, right from the assembly file,
now that we can do that.

[Note: Al had this export in the early version of a patch in patchwork
https://patchwork.kernel.org/patch/8166731/ but then the export was
removed in the mainline version in e007c53397ac -- hence RFC tag. ]
