From: Thor Thayer <tthayer@xxxxxxxxxxxxxxxxxxxxx>
In preparation for additional memory module ECCs, the
IRQ function will check a panic flag before doing a
kernel panic on double bit errors. ECCs on buffers
will not cause a kernel panic on DBERRs.
Signed-off-by: Thor Thayer <tthayer@xxxxxxxxxxxxxxxxxxxxx>

v2 New patch. Add panic flag to IRQ function.
