------------------------------------------------------
Subject: SERIAL: allow shared 8250_pnp interrupts
From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>
PNP devices can use shared interrupts, so check to see whether we'll need
SA_SHIRQ for request_irq().
The builtin PDH UART on the HP rx8640 is an example of an ACPI/PNP device
that uses a shareable level-triggered, active-low interrupt. The interrupt
can be shared in very large I/O configurations or by artificially lowering
IA64_DEF_LAST_DEVICE_VECTOR.
