Ian Dowse 58164331e3 Save and restore the interrupt Edge/Level Control Registers (ELCR)
across system suspends on the Intel 82371AB PCI-ISA bridge. On a
Sony Vaio C1XD that I have, these registers are not set correctly
after an ACPI resume. The result is that after resuming, a shared
IRQ is left in edge-triggered mode so the interrupt can later become
jammed in a state where the line remains asserted, but the handler
is never called.
