2007-07-20[ARM] 4506/1: HP Jornada 7XX: Addition of SSP Platform DriverKristoffer Ericson
These patches add full SSP/MCU support for the HP Jornada 720 machine. Its needed to handle keyboard, touchscreen, battery and backlight/lcd. The main driver exports functions and the header file exports the command values. When talking to the MCU the general procedure is to start MCU, send command (using ssp_inout(command)), the proper reply is always TXDUMMY. After receiving TXDUMMY you can send the value you wish pushed (for example brightness level). End with ssp_end() so the spinlock gets unlocked. Drivers using this havent been implemented yet, but will shortly. Signed-off-by: Kristoffer Ericson <Kristoffer.ericson@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-20[ARM] 4504/1: nommu: Fix the ARMv6 support for MMU-less platformsCatalin Marinas

2007-07-20mm: Remove slab destructors from kmem_cache_create().Paul Mundt
Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

2007-07-19define new percpu interface for shared dataFenghua Yu
per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

This patch completes Linus's wish that the fault return codes be made into bit flags, which I agree makes everything nicer.

2007-07-12[ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma codeEric Miao
Since the number of dma channels varies between pxa25x and pxa27x, it introduces some specific code in dma.c. This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-12[ARM] pxa: Fix PXA27x suspend type validation, remove pxa_pm_prepare()Russell King
pxa_pm_prepare() tried to validate the suspend method type. As noted in previous commits: eb9289eb20df6b54214c45ac7c6bf5179a149026 9c372d06ce9ddf65e1393f9ea22a6d6bd5f96b42 e8c9c502690efd24b7055bf608e7a3c34216848b the checking of the suspend type in the 'prepare' method is the wrong place to do this; use the 'valid' method instead. This means that pxa_pm_prepare() can be entirely removed. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] pxa: move pm_ops structure into CPU specific filesRussell King
Move the pm_ops structure into the PXA25x and PXA27x support files. Remove the old pxa_pm_prepare() function, and rename the both pxa_cpu_pm_prepare() functions as pxa_pm_prepare(). We'll fix that later. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-12[ARM] pxa: remove useless pxa_pm_finish() functionRussell King
pxa_pm_finish() does nothing but return zero. The core code does nothing with this return value, and will not try to call the finish method in the pm_ops structure if it is NULL. Therefore, we can remove this useless function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4453/1: Fully Decode ARM instruction set state in show_regs() tombstoneGeorge G. Davis
The ARM show_regs() tombstone only partially decodes which ARM ISA was executing at the time a fault occurred displaying either "(T)" for the Thumb case or nothing at all for other cases. This patch therefore explicitly identifies which state the processor is in at the time of a fault: ARM, Thumb, Jazelle or JazelleEE. Signed-off-by: George G.

2007-07-12[ARM] 4423/1: add ATAGS supportBill Gatliff
Examines the ATAGS pointer (r2) at boot, and interprets a nonzero value as a reference to an ATAGS structure. A suitable ATAGS structure replaces the kernel's command line. Signed-off-by: Bill Gatliff <bgat@billgatliff.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4393/2: ARMv7: Add uncompressing code for the new CPU Id formatCatalin Marinas
The current arch/arm/boot/compressed/head.S code only supports cores to ARMv6 with the old CPU Id format. This patch adds support for the new ARMv6 with the new CPU Id and ARMv7 cores that no longer have the ARMv4 cache operations.
