Merge branch 'ixp4xx' of git://git.kernel.org/pub/scm/linux/kernel/git/chris/linux-2.6
* 'ixp4xx' of git://git.kernel.org/pub/scm/linux/kernel/git/chris/linux-2.6:
IXP4xx: GTWX5715 platform only has two PCI IRQ lines, not four.
IXP4xx: Introduce IXP4XX_GPIO_IRQ(n) macro and convert IXP4xx platform files.
IXP4xx: move Gemtek GTWX5715 platform macros to the platform code.
IXP4xx: Remove unused Motorola PrPMC1100 platform macros.
IXP4xx: move FSG platform macros to the platform code.
IXP4xx: move DSM G600 platform macros to the platform code.
IXP4xx: move NAS100D platform macros to the platform code.
IXP4xx: move NSLU2 platform macros to the platform code.
IXP4xx: move Coyote platform macros to the platform code.
IXP4xx: move AVILA platform macros to the platform code.
IXP4xx: move IXDP425 platform macros to the platform code.
IXP4xx: Extend PCI MMIO indirect address space to 1 GB.
IXP4xx: Fix compilation failure with CONFIG_IXP4XX_INDIRECT_PCI.
IXP4xx: Drop "__ixp4xx_" prefix from in/out/ioread/iowrite functions for clarity.
IXP4xx: Rename indirect MMIO primitives from __ixp4xx_* to __indirect_*.
IXP4xx: Ensure index is positive in irq_to_gpio() and npe_request().
ARM: fix insl() and outsl() endianness on IXP4xx architecture.
IXP4xx: Fix normally-disabled debugging text in drivers/net/arm/ixp4xx_eth.c.
IXP4xx: change the timer base frequency to 66.666000 MHz.
