2012-07-02iommu/amd: fix type bug in flush codeDan Carpenter
write_file_bool() modifies 32 bits of data, so "amd_iommu_unmap_flush" needs to be 32 bits as well or we'll corrupt memory. Fortunately it looks like the data is aligned with a gap after the declaration so this is harmless in production.

2012-07-02dma-debug: debugfs_create_bool() takes a u32 pointerDan Carpenter
Even though it has "bool" in the name, you have pass a u32 pointer to debugfs_create_bool(). Otherwise you get memory corruption in write_file_bool(). Fortunately in this case the corruption happens in an alignment hole between variables so it doesn't cause any problems.

2012-07-02powerpc/xmon: Use cpumask iterator to avoid warningAnton Blanchard
We have a bug report where the kernel hits a warning in the cpumask code: WARNING: at include/linux/cpumask.h:107 Which is: WARN_ON_ONCE(cpu >= nr_cpumask_bits); The backtrace is: cpu_cmd cmds xmon_core xmon die xmon is iterating through 0 to NR_CPUS. I'm not sure why we are still open coding this but iterating above nr_cpu_ids is definitely a bug. This patch iterates through all possible cpus, in case we issue a system reset and CPUs in an offline state call in. Perhaps the old code was trying to handle CPUs that were in the partition but were never started (eg kexec into a kernel with an nr_cpus= boot option). They are going to die way before we get into xmon since we haven't set any kernel state up for them.

2012-07-01x86, microcode: Sanitize per-cpu microcode reloading interfaceBorislav Petkov
Microcode reloading in a per-core manner is a very bad idea for both major x86 vendors. And the thing is, we have such interface with which we can end up with different microcode versions applied on different cores of an otherwise homogeneous wrt (family,model,stepping) system. So turn off the possibility of doing that per core and allow it only system-wide. This is a minimal fix which we'd like to see in stable too thus the more-or-less arbitrary decision to allow system-wide reloading only on the BSP: $ echo 1 > /sys/devices/system/cpu/cpu0/microcode/reload ... and disable the interface on the other cores: $ echo 1 > /sys/devices/system/cpu/cpu23/microcode/reload -bash: echo: write error: Invalid argument Also, allowing the reload only from one CPU (the BSP in that case) doesn't allow the reload procedure to degenerate into an O(n^2) deal when triggering reloads from all /sys/devices/system/cpu/cpuX/microcode/reload sysfs nodes simultaneously. A more generic fix will follow.

2012-07-01ARM: imx: enable SPARSE_IRQ for imx platformShawn Guo
As all irqchips on imx have been changed to allocate their irq_descs, and all unneeded mach/irqs.h inclusions on imx have been cleaned up, now it's time to select SPARSE_IRQ for imx/mxc. The SPARSE_IRQ support forces irqs allocation starting from 16. All those static irq number definition for SoCs need to shift 16 to keep non-DT boot works. With all those static IRQ number and start definitions removed from mach/irqs.h, the header becomes just a container of a couple of mach-imx specific irq/fiq calls. Since mach/irqs.h is not included by asm/irq.h now, the users of mxc_set_irq_fiq needs to explicitly include mach/irqs.h themselves.

2012-07-01ARM: 7438/1: fill possible PMD empty section gapsNicolas Pitre
On ARM with the 2-level page table format, a PMD entry is represented by two consecutive section entries covering 2MB of virtual space. However, static mappings always were allowed to use separate 1MB section entries. This means in practice that a static mapping may create half populated PMDs via create_mapping(). Since commit 0536bdf33f (ARM: move iotable mappings within the vmalloc region) those static mappings are located in the vmalloc area. We must ensure no such half populated PMDs are accessible once vmalloc() or ioremap() start looking at the vmalloc area for nearby free virtual address ranges, or various things leading to a kernel crash will happen.

2012-07-01ARM: davinci: add runtime PM support for clock managementKevin Hilman
Add runtime PM core support to davinci by using the pm_clk infrastructure of the PM core. When runtime PM is enabled, the davinci runtime PM implementation will use the pm_clk layer to enable/disable clocks on demand. When runtime PM is disabled, the pm_clk core will automatically enable clocks when the driver is bound and disable clocks when the driver is unbound. Cc: Mark A.

2012-07-01PM / Domains: Do not stop devices after restoring their statesRafael J. Wysocki
While resuming a device belonging to a PM domain, pm_genpd_runtime_resume() calls __pm_genpd_restore_device() to restore its state, if necessary. The latter starts the device, using genpd_start_dev(), restores its state, using genpd_restore_dev(), and then stops it, using genpd_stop_dev(). However, this last operation is not necessary, because the device is supposed to be operational after pm_genpd_runtime_resume() has returned and because of it pm_genpd_runtime_resume() has to call genpd_start_dev() once again for the "restored" device, which is inefficient. To make things more efficient, remove the call to genpd_stop_dev() from __pm_genpd_restore_device() and the direct call to genpd_start_dev() from pm_genpd_runtime_resume(). [Of course, genpd_start_dev() still has to be called by it for devices with the power.irq_safe flag set, because __pm_genpd_restore_device() is not executed for them.] This change has been tested on the SH7372 Mackerel board.
