We now cache the MSI-X capability offset in the struct pci_dev, so no need to find the capability again.

The kernel crashes while resuming from AFTR idle mode. It happens because L2 cache was not going into retention state. This patch configures the USE_RETENTION bit of ARM_L2_OPTION register so that it does not depend on MANUAL_L2RSTDISABLE_CONTROL of ARM_COMMON_OPTION register for L2RSTDISABLE signal.

This is the meat of the series which prevents any dcache alias creation by always keeping the U and K mapping of a page congruent. If a mapping already exists, and other tries to access the page, prev one is flushed to physical page (wback+inv) Essentially flush_dcache_page()/copy_user_highpage() create K-mapping of a page, but try to defer flushing, unless U-mapping exist. When page is actually mapped to userspace, update_mmu_cache() flushes the K-mapping (in certain cases this can be optimised out) Additonally flush_cache_mm(), flush_cache_range(), flush_cache_page() handle the puring of stale userspace mappings on exit/munmap... flush_anon_page() handles the existing U-mapping for anon page before kernel reads it via the GUP path. Note that while not complete, this is enough to boot a simple dynamically linked Busybox based rootfs Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

Commit 6770b211 (ARM: OMAP2+: Export SoC information to userspace) had some broken return value handling as noted by Russell King: + soc_dev = soc_device_register(soc_dev_attr); + if (IS_ERR_OR_NULL(soc_dev)) { + kfree(soc_dev_attr); + return; + } + + parent = soc_device_to_device(soc_dev); + if (!IS_ERR_OR_NULL(parent)) + device_create_file(parent, &omap_soc_attr); This is nonsense. For the first, IS_ERR() is sufficient. For the second, tell me what error checking is required in the return value of this function: struct device *soc_device_to_device(struct soc_device *soc_dev) { return &soc_dev->dev; } when you've already determined that the passed soc_dev is a valid pointer. If you read the comments against the prototype: /** * soc_device_to_device - helper function to fetch struct device * @soc: Previously registered SoC device container */ struct device *soc_device_to_device(struct soc_device *soc); if "soc" is valid, it means the "previously registered SoC device container" must have succeeded and that can only happen if the struct device has been registered. Ergo, there will always be a valid struct device pointer for any registered SoC device container. Therefore, if soc_device_register() succeeds, then the return value from soc_device_to_device() will always be valid and no error checking of it is required. Simples. The rule as ever applies here: get to know the APIs your using and don't fumble around in the dark hoping that you'll get this stuff right. Fix it as noted by Russell.

Reorganize some of the GIC clocksource driver code. Below is a list of the various changes. * No longer select CSRC_GIC by default for Malta platform. * Limit choice for either the GIC or R4K clocksource, not both. * Change location in Makefile. * Created new 'gic_read_count' function in common 'irq-gic.c' file. * Change 'git_hpt_read' function in 'csrc-gic.c' to use new function. * Surround GIC specific code in Malta platform code with #ifdef's. * Only initialize the GIC clocksource if it was selected. Original code called it unconditionally if a GIC was found. Signed-off-by: NSteven J. Hill <Steven.Hill@imgtec.com>

Partially revert commit e0c14a260d66ba35935600d6435940a566fe806b and turn off LL/SC when building a pure microMIPS kernel.
