2010-07-27perf, powerpc: Use perf_sample_data_init() for the FSL codePeter Zijlstra
We should use perf_sample_data_init() to initialize struct perf_sample_data. As explained in the description of commit dc1d628a ("perf: Provide generic perf_sample_data initialization"), it is possible for userspace to get the kernel to dereference data.raw, so if it is not initialized, that means that unprivileged userspace can possibly oops the kernel. Using perf_sample_data_init makes sure it gets initialized to NULL. This conversion should have been included in commit dc1d628a, but it got missed.

2010-07-27ARM: call machine_shutdown() from machine_halt(), etcRussell King
x86 calls machine_shutdown() from the various machine_*() calls which take the machine down ready for halting, restarting, etc, and uses this to bring the system safely to a point where those actions can be performed. Such actions are stopping the secondary CPUs. So, change the ARM implementation of these to reflect what x86 does. This solves kexec problems on ARM SMP platforms, where the secondary CPUs were left running across the kexec call. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-07-27ARM: SMP: Always enable clock event broadcast supportRussell King
The TWD local timers are unable to wake up the CPU when it is placed into a low power mode, eg. C3. Therefore, we need to adapt things such that the TWD code can cope with this. We do this by always providing a broadcast tick function, and marking the fact that the TWD local timer will stop in low power modes. This means that when the CPU is placed into a low power mode, the core timer code marks this fact, and allows an IPI to be given to the core.

2010-07-27ARM: Factor out common code from cpu_proc_fin()Russell King
All implementations of cpu_proc_fin() start by disabling interrupts and then flush caches. Rather than have every processors proc_fin() implementation do this, move it out into generic code - and move the cache flush past setup_mm_for_reboot() (so it can benefit from having caches still enabled.) This allows cpu_proc_fin() to become independent of the L1/L2 cache types, and eventually move the L2 cache flushing into the L2 support code.

Unfortunately, we don't have runtime check for 'K' extension, so we can't check for it. Signed-off-by: Kirill A.

2010-07-27ARM: 6255/1: Workaround infinity loop in handling of translation faultsKirill A. Shutemov
On ARM one Linux PGD entry contains two hardware entries (see page tables layout in pgtable.h). We normally guarantee that we always fill both L1 entries. But create_mapping() doesn't follow the rule. It can create inidividual L1 entries, so here we have to call pmd_none() check in do_translation_fault() for the entry really corresponded to address, not for the first of pair.

2010-07-27ARM: DMA coherent allocator: align remapped addressesRussell King
The DMA coherent remap area is used to provide an uncached mapping of memory for coherency with DMA engines. Currently, we look for any free hole which our allocation will fit in with page alignment. However, this can lead to fragmentation of the area, and allows small allocations to cross L1 entry boundaries. This is undesirable as we want to move towards allocating sections of memory. Align allocations according to the size, limiting the alignment between the page and section sizes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Implementation of the ST-Ericsson baudrate extension in the PL011 block. In this modified variant it is possible to change the sampling factor from 16 to 8, and thanks to this we can get higher baudrates while still using the same peripheral clock.

2010-07-27ARM: 6225/1: make TCM allocation static and common for all archsLinus Walleij
This changes the TCM handling so that a fixed area is reserved at 0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but XScale does not have TCM so the mechanisms are mutually exclusive. This change is needed to make TCM detection more dynamic while still being able to compile code into it, and is a must for the unified ARM goals: the current TCM allocation at different places in memory for each machine would be a nightmare if you want to compile a single image for more than one machine with TCM so it has to be nailed down in one place.

2010-07-26xfs simplify and speed up direct I/O completionsChristoph Hellwig
Our current handling of direct I/O completions is rather suboptimal, because we defer it to a workqueue more often than needed, and we perform a much to aggressive flush of the workqueue in case unwritten extent conversions happen. This patch changes the direct I/O reads to not even use a completion handler, as we don't bother to use it at all, and to perform the unwritten extent conversions in caller context for synchronous direct I/O. For a small I/O size direct I/O workload on a consumer grade SSD, such as the untar of a kernel tree inside qemu this patch gives speedups of about 5%. Getting us much closer to the speed of a native block device, or a fully allocated XFS file.
