Subject[PATCH 2.6.27-rc4][RESEND] irq: irq and pci_ids patch for Intel Ibex Peak DeviceIDs
Date
This patch updates the Intel Ibex Peak (PCH) LPC and SMBus Controller DeviceIDs.

The LPC Controller ID is set by Firmware within the range of 0x3b00-3b1f. This range is included in pci_ids.h using min and max values, and irq.c now has code to handle the range (in lieu of 32 additions to a SWITCH statement).

The SMBus Controller ID is a fixed-value and will not change.
