2008-10-19mfd: do tcb6393xb state restore on resume only if requestedDmitry Baryshkov
As requested by Ian make state restore only if it's requested by platform data: some platforms do correctly save the state of the chip during suspend/resume, but some (like tosa) incorrectly power off the chip at suspend, so the driver supports restoring some bits of the tc6393xb state (not full, merely enough to support resume on tosa). With this patch this code is disabled by default. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Acked-by: Ian Molton <spyro@f2s.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>

2008-10-19[ARM] Orion: activate workaround for 88f6183 SPI clock erratumNicolas Pitre
Commit 2ede90ca78500ca0ffeee19d7812d345f8ad152d adds 6183 support, but the SPI support in there doesn't work since it depends on a 6183 SPI unit erratum fix that only just went upstream, via commit 2bec19feabd53cba75e9dab0e79afbe868a37113. Signed-off-by: Nicolas Pitre <nico@marvell.com>

2008-10-19[ARM] mv78xx0: force link speed/duplex on eth2/eth3Lennert Buytenhek
On the mv78xx0 development board, eth2 and eth3 do not have corresponding PHYs, but are internally connected, as a way of facilitating communication between the two CPU cores. Since there are no PHYs, we need to tell the network driver explicitly to force the link on eth2 and eth3 up, to 1000 Mb/s full duplex.

2008-10-18Export kmap_atomic_pfn for DRM-GEM.Eric Anholt
The driver would like to map IO space directly for copying data in when appropriate, to avoid CPU cache flushing for streaming writes. kmap_atomic_pfn lets us avoid IPIs associated with ioremap for this process.

Madison cpus support 64 TR registers. Increase IA64_TR_ALLOC_MAX to 64. Also fixup the messages that get printed when this limit is exceeded. Repeating for every cpu is too noisy. Signed-off-by: Tony Luck <tony.luck@intel.com>

2008-10-17[IA64] Add Variable Page Size and IA64 Support in Intel IOMMUFenghua Yu
The patch contains Intel IOMMU IA64 specific code. It defines new machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush function, etc. For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected, dig_vtd is used for machinve vector. Otherwise, kernel falls back to dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off" can be used to force kernel to boot dig machine vector.

2008-10-17ia64/pv_ops/xen: elf note based xen startup.Isaku Yamahata
This patch enables elf note based xen startup for IA-64, which gives the kernel an early hint for running on xen like x86 case. In order to avoid the multi entry point, presumably extending booting protocol(i.e. extending struct ia64_boot_param) would be necessary. It probably means that elilo also needs modification.
