Patch from Tony Lindgren Allows translation of shared memory addresses for devices using dma-mapping. In some cases the device DMA address is different from the ARM DMA address, for example with some USB OHCI controllers. For more background information, please see the ARM Linux mailing list thread "OHCI controller".

Patch from Nicolas Pitre Let's make it coherent with what the actual code is doing and has always done, even in 2.4. Nobody complained about this so let's just fix the comment. The most natural usage pattern for this is a base address and a size so it's more efficient to have an exclusive end address anyway.

Patch from Ian Campbell I've seen comments several times that various PXA drivers update CKEN in an unsafe manner. This patch consolidates this code into a single function pxa_set_cken() and updates all the in tree drivers to use it.

Patch from Ian Campbell The pxafb driver incorrectly allocates 17 u32's for a 16 entry pseudo palette.

This cset adds the code to handle the hardware vector floating point unit found on some ARM926 and later CPUs. The hardware provides an implementation for the common cases, and bounces exceptions for other cases, which have to be handled in software, and signalling SIGFPE as appropriate.

Patch from Marc Singer [if's replaced by ifdef's.] While the BLOB boot loader doesn't support it, there are two others, UBOOT and Logic's LOLO, that will initialize the SDRAM controller such that the memory appears as a contiguous region. This layout to be required for WinCE and, thus, is the default for these loaders. The memory organization had been optimized for discontiguous blocks. Now, it supports a default mode that is compatible with all of the bootloaders as well as options to optimize for either contiguous or discontiguous models. Withing, there is also a slight change to the way that the DEBUG_LL macros select the UART address. Now it uses immediate constants exclusively.

Patch from Ian Campbell Sorry, 1926/2 was missing a brace. Fixed here. Previous commentry: I have corrected the grayscale conversion to correctly use the upper byte rather than the lower one. As requested I have also left the actual grayscale conversion where it was this time and just dealt with the palette differences in pxafb_setpalettereg. fb_alloc_cmap is only called when bits_per_pixel is < 16, otherwise any existing cmap is freed. I also fixed up all the spaces and brackets issues (not just the one you raised previously) this introduces some noise in the patch, if you'd like the two patches separately please ask.

Since peripheral clocks are be derived in SoC or even platform specific ways, we need a way to keep this information out of the drivers. AMBA Primecells are defined in terms of functional units where clocks are derived from external sources, and it is up to the SoC designer to determine where to derive those clocks from. Therefore, we provide a very basic API which allows platforms to provide this information in a generic manner to their peripherals. This framework also allows peripherals to shut down unused clock sources when they're not in use.

From: Nick Piggin <nickpiggin@yahoo.com.au> nfs_writepage() refuses to write back mapped pages at all on the page reclaim path, causing systems to get locked up when there's a lot of dirty mmapped data around. The patch changes NFS so that it will start I/O against these pages. The code as it stands is designed to defer writeout to pdflush which can do larger, more efficient I/Os. But there shouldn't be much traffic by this path, and going slow is better than not going at all. Patch originally from Trond.

VIA chipsets are broken and don't work with IOMMU enabled. For some mysterious reason (the IOMMU logic is actually in the CPU) they manage to corrupt all data going through the aperture to PCI devices. There was a workaround previously that enabled the slower softmmu when VIA is detected on the normal IOMMU path (when there is more than 3GB of memory). But CONFIG_IOMMU_DEBUG took a short cut that was not handled, which ended up with VIA systems not booting when this option is enabled. This patch enables the workaround with CONFIG_IOMMU_DEBUG/iommu=force too

The fast system-call fall-back-path has a race: it reads PSR, modifies some bits, then writes back the new PSR. Unfortunately, the contents of PSR may change between reading and writing it. For example, an interrupt could occur which could trigger a context-switch. The context-switch might in turn flush the floating-point-high (FPH) partition to memory, clear PSR.MFH, and set PSR.DFH. To prevent this race, the patch below turns off PSR.I before reading PSR. This fixes a floating-point corruption problem that was observed on a system with a libc which has the fast system-call support enabled. The performance impact is minimal (on the order of a handful of cycles).

I waffled over this for ages. On balance, I think it's best to mark those bh's as uptodate. And on reflection, I'm not sure why we go bringing ramdisk blockdev pages uptodate all over the place anyway. But ramdisk is weird and it passes testing. Let those dogs sleep.
