* cgroups: fix API thinkoMichael S. Tsirkin2010-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | Add cgroup_attach_task_all() The existing cgroup_attach_task_current_cg() API is called by a thread to attach another thread to all of its cgroups; this is unsuitable for cases where a privileged task wants to attach itself to the cgroups of a less privileged one, since the call must be made from the context of the target task. This patch adds a more generic cgroup_attach_task_all() API that allows both the source task and to-be-moved task to be specified. cgroup_attach_task_current_cg() becomes a specialization of the more generic new function.

* gcov: fix null-pointer dereference for certain module typesPeter Oberparleiter2010-09-09
| | | | | | | | | | | | | | | | | | The gcov-kernel infrastructure expects that each object file is loaded only once. This may not be true, e.g. when loading multiple kernel modules which are linked to the same object file. As a result, loading such kernel modules will result in incorrect gcov results while unloading will cause a null-pointer dereference. This patch fixes these problems by changing the gcov-kernel infrastructure so that multiple profiling data sets can be associated with one debugfs entry. It applies to 2.6.36-rc1.

* O_DIRECT: fix the splitting up of contiguous I/OJeff Moyer2010-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c2c6ca4 (direct-io: do not merge logically non-contiguous requests) introduced a bug whereby all O_DIRECT I/Os were submitted a page at a time to the block layer. The problem is that the code expected dio->block_in_file to correspond to the current page in the dio. In fact, it corresponds to the previous page submitted via submit_page_section. This was purely an oversight, as the dio->cur_page_fs_offset field was introduced for just this purpose. This patch simply uses the correct variable when calculating whether there is a mismatch between contiguous logical blocks and contiguous physical blocks (as described in the comments). I also switched the if conditional following this check to an else if, to ensure that we never call dio_bio_submit twice for the same dio (in theory, this should not happen, anyway). I've tested this by running blktrace and verifying that a 64KB I/O was submitted as a single I/O. I also ran the patched kernel through xfstests' aio tests using xfs, ext4 (with 1k and 4k block sizes) and btrfs and verified that there were no regressions as compared to an unpatched kernel.

* rtc-bfin: fix state restoration when resumingMike Frysinger2010-09-09
| | | | | | | | | | | | | | | | | | | | | | | Much (but not all) of the RTC state is kept in the RTC peripheral which has its own power domain. Periodically (1 HZ), that state is synced from one power domain to the other (peripheral->core). When we are resuming, we need to wait for the sync to occur so that we don't get a mismatch of reading undefined state in the rest of the driver. Further, once the externally maintained bits have been synced back into the core, we then need to restore the bits maintained in the core. In our particular case, that is just the write completion interrupt bit. If we don't do any of this, working with the RTC causes ~5 second delays from time to time after waking up due to the write completion interrupt never firing.

* mmc: avoid getting CID on SDIO-only cardsDavid Vrabel2010-09-09
| | | | | | | | | | | | | | | | The introduction of support for SD combo cards breaks the initialization of all CSR SDIO chips. The GO_IDLE (CMD0) in mmc_sd_get_cid() causes CSR chips to be reset (this is non-standard behavior). When initializing an SDIO card check for a combo card by using the memory present bit in the R4 response to IO_SEND_OP_COND (CMD5). This avoids the call to mmc_sd_get_cid() on an SDIO-only card.

We've managed to reduce the | problem to the following snippet, which is run from a kthread in a | continuous loop: | | void *virtAddr; | dma_addr_t physAddr; | unsigned int numBytes = 256; | | for (;;) { | virtAddr = dma_alloc_writecombine(NULL, | numBytes, &physAddr, GFP_KERNEL); | if (virtAddr == NULL) { | printk(KERN_ERR "Running out of memory\n"); | break; | } | | /* access DMA memory allocated */ | tmp = virtAddr; | *tmp = 0x77; | | /* free DMA memory */ | dma_free_writecombine(NULL, | numBytes, virtAddr, physAddr); | | ...sleep here... | } | | By itself, the code will run forever with no issues. However, as we | increase our bus traffic (typically using DMA) then the *tmp = 0x77 | line will eventually cause a page fault. If we add a small delay (a | few microseconds) before the *tmp = 0x77, then we don't see a page | fault, even under heavy load. A dsb() is required after modifying the PTE entries to ensure that they will always be visible. Add this dsb().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7cfe24947 ("ARM: AMBA: Add pclk support to AMBA bus infrastructure") changed AMBA bus to handle the PCLK automatically. However, in EP93xx clock initialization is arch_initcall which is done later than AMBA device identification. This causes amba_get_enable_pclk() to fail resulting device where UARTs are not functional. So change ep93xx_clock_init() to be postcore_initcall.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows control of the leds on the AP4EVB board by kernel events (triggers) like mmc0/mmc1. In userland, the leds won't be available anymore over /sys/class/gpio but via /sys/class/leds. Signed-off-by: Arnd Hannemann <arnd@arndnet.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

If Runtime PM is disabled then the clocks will be enabled before ->probe() and disabled after ->remove().

| * | | | ARM: 6343/1: wire up fanotify and prlimit64 syscalls on ARMMikael Pettersson2010-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 2.6.36-rc kernel added three new system calls: fanotify_init, fanotify_mark, and prlimit64. This patch wires them up on ARM. The only non-trivial issue here is the u64 argument to sys_fanotify_mark(), but it is the 3rd argument and thus passed in r2/r3 in both kernel and user space, so it causes no problems. Tested with a 2.6.36-rc2 EABI kernel on an ixp4xx machine.

| * | | | ARM: 6330/1: perf: reword comments relating to perf_event_do_pendingWill Deacon2010-09-01
| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is purely a cosmetic change to the ARM perf backend because the current comments about the relationship between NMIs, interrupt context and perf_event_do_pending are misleading. This patch updates the comments so that they reflect what the code actually does (which is in line with other architectures).

* | | | lglock: make lg_lock_global() actually lock globallyJonathan Corbet2010-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lg_lock_global() currently only acquires spinlocks for online CPUs, but it's meant to lock all possible CPUs. Lglock-protected resources may be associated with removed CPUs - and, indeed, that could happen with the per-superblock open files lists. At Nick's suggestion, change for_each_online_cpu() to for_each_possible_cpu() to protect accesses to those resources.
