Subject: [PATCHv2 3/7] EDAC, altera: Move Arria10 IRQ function
From: Thor Thayer <tthayer@...nsource.altera.com>
In preparation for additional memory module ECCs, the IRQ and
check_deps() functions are being made available to all the
memory buffers. Move it outside of the OCRAM only area.
Signed-off-by: Thor Thayer <tthayer@...nsource.altera.com>

v2 New patch. Move shared functions outside OCRAM only area.
