Switchtec Updates

Hi Bjorn,

Blease accept the following two patches. The first adds a couple more device IDs for the Switchtec driver. The second adds a new event type for it to report.

Thanks,

Logan

Kelvin Cao (1):
switchtec: Add device IDs for PSX 24xG3 and PSX 48xG3

Logan Gunthorpe (1):
switchtec: Added Global Fabric Manager Server (GFMS) event

2.11.0

Add a new event type that is newly exposed by recent firmware. The event will never occur if the firmware is too old. If user space tries to use this event in an older kernel, it will just get an EINVAL which is perfectly acceptable in the existing user space code.
