[PATCH] libata: set IRQF_SHARED for legacy PCI IDE IRQs
There are machines out there which share legacy PCI IDE IRQs w/ other
devices. libata SFF interrupt/HSM code is ready for shared IRQ and
has been setting IRQF_SHARED for devices in native PCI mode. Device
in legacy mode is still a PCI device and thus supposedly uses
active-low level triggered IRQ.
Machines with such setup should be quite rare and w/o this flag libata
is likely to fail loading and render the system unuseable. Also, IDE
driver has been setting IRQF_SHARED for devices in legacy mode for a
looooong time.
