We currently assume that the DMA Slave Config will be fully populated by the platform, however some DMA Engines make decisions based on zero (default) flags such as DMA_SLAVE_BUSWIDTH_UNDEFINED and as this is a static declaration we need to memset it to clear the data area.

Originally snd_hrtimer_callback() used iprtd->period_time for some jiffies based estimation to determine the right moment to call snd_pcm_period_elapsed(). As timer drifts may well be a problem, this was changed in commit b4e82b5b to be based on buffer transmission progress, using iprtd->offset and runtime->buffer_size to calculate the amount of data since last period had elapsed. Unfortunately, iprtd->offset counts in bytes, while runtime->buffer_size counts frames, so adding these to find some delta is like comparing apples and oranges, and eventually results in negative delta values every now and then. This is no big harm, because it simply causes snd_pcm_period_elapsed() being called more often than necessary, as negative delta is taken for a large unsigned value by implicit conversion rule. Nonetheless, the calculation is broken, so one would replace the runtime->buffer_size by its equivalent in bytes. But then, there are chances snd_pcm_period_elapsed() is called late, because calculating the moment for the elapsed period into delta is based against the iprtd->last_offset, which is not necessarily the first byte of the period in question, but some random byte which the FIQ handler left us with in r8/r9 by accident. Again, negative impact is low, as there are plenty of periods already prefilled with data, and snd_pcm_period_elapsed() will probably be called latest when the following period is reached. However, the calculation is conceptually broken, and we are best off removing the clever stuff altogether. snd_pcm_period_elapsed() is now simply called once everytime snd_hrtimer_callback() is run, which may not be most accurate, but at least this way we are quite sure we dont miss an end of period. There is not much extra effort wasted by superfluous calls to snd_pcm_period_elapsed(), as the timer frequency closely matches the period size anyway.

Negative message lengths make no sense -- so don't do negative queue lenghts or identifier counts. Prevent them from getting negative. Also change the underlying data types to be unsigned to avoid hairy surprises with sign extensions in cases where those variables get evaluated in unsigned expressions with bigger data types, e.g size_t. In case a user still wants to have "unlimited" sizes she could just use INT_MAX instead.

A vmalloc fault needs to sync up PGD/PTE entry from init_mm to current task's "active_mm". ARC vmalloc fault handler however was using mm. A vmalloc fault for non user task context (actually pre-userland, from init thread's open for /dev/console) caused the handler to deref NULL mm (for mm->pgd) The reasons it worked so far is amazing: 1. By default (!SMP), vmalloc fault handler uses a cached value of PGD. In SMP that MMU register is repurposed hence need for mm pointer deref. 2. In pre-3.12 SMP kernel, the problem triggering vmalloc didn't exist in pre-userland code path - it was introduced with commit 20bafb3d "n_tty: Move buffers into n_tty_data" Signed-off-by: NVineet Gupta <vgupta@synopsys.com> Cc: Gilad Ben-Yossef <gilad@benyossef.com> Cc: Noam Camus <noamc@ezchip.com> Cc: stable@vger.kernel.org #3.10 and 3.11 Cc: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

This patch uses CONFIG_PAGE_OFFSET to filter symbols which are not in kernel address space because these symbols are generally for generating code purpose and can't be run at kernel mode, so we needn't keep them in /proc/kallsyms. For example, on ARM there are some symbols which may be linked in relocatable code section, then perf can't parse symbols any more from /proc/kallsyms, this patch fixes the problem (introduced b9b32bf7) Cc: Russell King <linux@arm.linux.org.uk> Cc: linux-arm-kernel@lists.infradead.org Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: NMing Lei <tom.leiming@gmail.com> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Cc: stable@vger.kernel.org

When a memcg is deleted mem_cgroup_reparent_charges() moves charged memory to the parent memcg. As of v3.11-9444-g3ea67d06 "memcg: add per cgroup writeback pages accounting" there's bad pointer read. The goal was to check for counter underflow. The counter is a per cpu counter and there are two problems with the code: (1) per cpu access function isn't used, instead a naked pointer is used which easily causes oops. (2) the check doesn't sum all cpus Test: $ cd /sys/fs/cgroup/memory $ mkdir x $ echo 3 > /proc/sys/vm/drop_caches $ (echo $BASHPID >> x/tasks && exec cat) & [1] 7154 $ grep ^mapped x/memory.stat mapped_file 53248 $ echo 7154 > tasks $ rmdir x <OOPS> The fix is to remove the check. It's currently dangerous and isn't worth fixing it to use something expensive, such as percpu_counter_sum(), for each reparented page. __this_cpu_read() isn't enough to fix this because there's no guarantees of the current cpus count. The only guarantees is that the sum of all per-cpu counter is >= nr_pages.
