2011-11-10ENGR00160878-2 mxc v4l2 output: new mxc v4l2 output driver based on videobufJason Chen
This new v4l2 output driver is based on videobuf, using dma contig alloc method. It creates video dev node for each display framebuffer begin from /dev/video16 by default. If need post-processing, this driver will do it by ipu pp driver which support: - resizing - CSC - rotate - deinterlacing If no need post-processing, the IPU IC will be bypassed as old driver, the buf will be set to fb buffer directly by crack fb smem_start. The user should do setting before streamon like below: 1. set output crop 2. set ctrl like rotate/vflip/hflip/deinterlacing motion 3. set fmt 4. reqbuf The new features compare to old driver: - support multi-instance - support user point buffer - runtime suspend/resume For suspend/resume, still has chance to meet issue on mx6q, will fix later.

2011-11-10ARM: 6941/1: cache: ensure MVA is cacheline aligned in flush_kern_dcache_areaWill Deacon
commit a248b13b21ae00b97638b4f435c8df3075808b5d upstream. The v6 and v7 implementations of flush_kern_dcache_area do not align the passed MVA to the size of a cacheline in the data cache. If a misaligned address is used, only a subset of the requested area will be flushed. This has been observed to cause failures in SMP boot where the secondary_data initialised by the primary CPU is not cacheline aligned, causing the secondary CPUs to read incorrect values for their pgd and stack pointers. This patch ensures that the base address is cacheline aligned before flushing the d-cache.

2011-11-10Fix memory leak in cpufreq_statsteven finney
commit 98586ed8b8878e10691203687e89a42fa3355300 upstream. When a CPU is taken offline in an SMP system, cpufreq_remove_dev() nulls out the per-cpu policy before cpufreq_stats_free_table() can make use of it. cpufreq_stats_free_table() then skips the call to sysfs_remove_group(), leaving about 100 bytes of sysfs-related memory unclaimed each time a CPU-removal occurs. Break up cpu_stats_free_table into sysfs and table portions, and call the sysfs portion early.

2011-11-10CPU hotplug, re-create sysfs directory and symlinksJacob Shin
commit 27ecddc2a9f99ce4ac9a59a0acd77f7100b6d034 upstream. When we discover CPUs that are affected by each other's frequency/voltage transitions, the first CPU gets a sysfs directory created, and rest of the siblings get symlinks. Currently, when we hotplug off only the first CPU, all of the symlinks and the sysfs directory gets removed. Even though rest of the siblings are still online and functional, they are orphaned, and no longer governed by cpufreq. This patch, given the above scenario, creates a sysfs directory for the first sibling and symlinks for the rest of the siblings. Please note the recursive call, it was rather too ugly to roll it out. And the removal of redundant NULL setting (it is already taken care of near the top of the function).

commit 3bd2cbb95543acf44fe123eb9f038de54e655eb4 upstream. With ARMv5+ and EABI, the compiler expects a 64-bit aligned stack so instructions like STRD and LDRD can be used.

2011-11-10smp_call_function_many: handle concurrent clearing of maskMilton Miller
commit 723aae25d5cdb09962901d36d526b44d4be1051c upstream. Mike Galbraith reported finding a lockup ("perma-spin bug") where the cpumask passed to smp_call_function_many was cleared by other cpu(s) while a cpu was preparing its call_data block, resulting in no cpu to clear the last ref and unlock the block. Having cpus clear their bit asynchronously could be useful on a mask of cpus that might have a translation context, or cpus that need a push to complete an rcu window. Instead of adding a BUG_ON and requiring yet another cpumask copy, just detect the race and handle it. Note: arch_send_call_function_ipi_mask must still handle an empty cpumask because the data block is globally visible before the that arch callback is made. And (obviously) there are no guarantees to which cpus are notified if the mask is changed during the call; only cpus that were online and had their mask bit set during the whole call are guaranteed to be called.

2011-11-10call_function_many: add missing orderingMilton Miller
commit 45a5791920ae643eafc02e2eedef1a58e341b736 upstream. Paul McKenney's review pointed out two problems with the barriers in the 2.6.38 update to the smp call function many code. First, a barrier that would force the func and info members of data to be visible before their consumption in the interrupt handler was missing. This can be solved by adding a smp_wmb between setting the func and info members and setting setting the cpumask; this will pair with the existing and required smp_rmb ordering the cpumask read before the read of refs. This placement avoids the need a second smp_rmb in the interrupt handler which would be executed on each of the N cpus executing the call request. (I was thinking this barrier was present but was not). Second, the previous write to refs (establishing the zero that we the interrupt handler was testing from all cpus) was performed by a third party cpu. This would invoke transitivity which, as a recient or concurrent addition to memory-barriers.txt now explicitly states, would require a full smp_mb(). However, we know the cpumask will only be set by one cpu (the data owner) and any preivous iteration of the mask would have cleared by the reading cpu. By redundantly writing refs to 0 on the owning cpu before the smp_wmb, the write to refs will follow the same path as the writes that set the cpumask, which in turn allows us to keep the barrier in the interrupt handler a smp_rmb instead of promoting it to a smp_mb (which will be be executed by N cpus for each of the possible M elements on the list). I moved and expanded the comment about our (ab)use of the rcu list primitives for the concurrent walk earlier into this function. I considered moving the first two paragraphs to the queue list head and lock, but felt it would have been too disconected from the code.

2011-11-10call_function_many: fix list delete vs add raceMilton Miller
commit e6cd1e07a185d5f9b0aa75e020df02d3c1c44940 upstream. Peter pointed out there was nothing preventing the list_del_rcu in smp_call_function_interrupt from running before the list_add_rcu in smp_call_function_many. Fix this by not setting refs until we have gotten the lock for the list. Take advantage of the wmb in list_add_rcu to save an explicit additional one. I tried to force this race with a udelay before the lock & list_add and by mixing all 64 online cpus with just 3 random cpus in the mask, but was unsuccessful. Still, inspection shows a valid race, and the fix is a extension of the existing protection window in the current code.
