2009-10-08mm, perf_event: Make vmalloc_user() align base kernel virtual address to SHMLBADavid Miller
When a vmalloc'd area is mmap'd into userspace, some kind of co-ordination is necessary for this to work on platforms with cpu D-caches which can have aliases. Otherwise kernel side writes won't be seen properly in userspace and vice versa. If the kernel side mapping and the user side one have the same alignment, modulo SHMLBA, this can work as long as VM_SHARED is shared of VMA and for all current users this is true. VM_SHARED will force SHMLBA alignment of the user side mmap on platforms with D-cache aliasing matters. The bulk of this patch is just making it so that a specific alignment can be passed down into __get_vm_area_node(). All existing callers pass in '1' which preserves existing behavior. vmalloc_user() gives SHMLBA for the alignment. As a side effect this should get the video media drivers and other vmalloc_user() users into more working shape on such systems. Signed-off-by: David S.

2009-10-08cgroups: update documentation of cgroups tasks and procs filesPaul Menage
Update documentation of cgroups tasks and procs files Document the cgroup.procs file. Clarify the semantics of the cgroup.procs and tasks files. Although the current cgroup.procs interface returns a sorted and uniqified list of pids, potential future performance enhancements could result in those properties being removed - explicitly document this aspect of the API. There are no existing users of cgroup.procs, so compatibility isn't an issue. There are users of the "tasks" file, but none that would appear to break in the event of the sorted property being broken. The standard "libcpuset" explicitly sorts the results of reading from the tasks file, and "libcg" and other users don't appear to care about ordering.

2009-10-08ksm: more on default valuesHugh Dickins
Adjust the max_kernel_pages default to a quarter of totalram_pages, instead of nr_free_buffer_pages() / 4: the KSM pages themselves come from highmem, and even on a 16GB PAE machine, 4GB of KSM pages would only be pinning 32MB of lowmem with their rmap_items, so no need for the more obscure calculation (nor for its own special init function). There is no way for the user to switch KSM on if CONFIG_SYSFS is not enabled, so in that case default run to KSM_RUN_MERGE. Update KSM Documentation and Kconfig to reflect the new defaults.

2009-10-08Blackfin: fix framebuffer mmap bug for nommuThomas Chou
The patch added a special get_unmapped_area for framebuffer which was hooked to the file ops in drivers/video/fbmem.c. This is needed since v2.6.29-rc1 where nommu vma management was updated, and mmap of framebuffer caused kernel BUG panic. You may turn on "Debug the global anon/private NOMMU mapping region tree" config to such message. As Documentation/nommu-mmap.txt said, "To provide shareable character device support, a driver must provide a file->f_op->get_unmapped_area() operation. The mmap() routines will call this to get a proposed address for the mapping." With this change, user space should call mmap for framebuffer using shared map. Or it can try shared map first, then private map if failed. This shared map usage is now consistent between mmu and nommu. The sys_ file may not be a good place for this patch. But there is a similar one for sparc. I tested a similar patch on nios2nommu, though I don't have a blackfin board to test.

In commit cb58160e ("RDMA/iwcm: Reject the connection when the cm_id is destroyed") a call to the provider's reject handler was added to destroy_cm_id() to fix a provider endpoint leak. This call needs to be done with interrupts enabled. So unlock and relock around this call. This is safe because: 1) the provider will do nothing with this endpoint until the iwcm either accepts or rejects. 2) the lock is only released after the iwcm state is changed, so an errant iwcm app that is destroying -and- rejecting the connection concurrently will get a failure on one of the calls.

2009-10-07ftrace: check for failure for all conversionsSteven Rostedt
Due to legacy code from back when the dynamic tracer used a daemon, only core kernel code was checking for failures. This is no longer the case. We must check for failures any time we perform text modifications. Cc: stable@kernel.org Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2009-10-07tracing: correct module boundaries for ftrace_releasejolsa@redhat.com
When the module is about the unload we release its call records. The ftrace_release function was given wrong values representing the module core boundaries, thus not releasing its call records. Plus making ftrace_release function module specific.

2009-10-07futex: fix requeue_pi key imbalanceDarren Hart
If futex_wait_requeue_pi() wakes prior to requeue, we drop the reference to the source futex_key twice, once in handle_early_requeue_pi_wakeup() and once on our way out. Remove the drop from the handle_early_requeue_pi_wakeup() and keep the get/drops together in futex_wait_requeue_pi().

2009-10-07amd64_edac: beef up DRAM error injectionBorislav Petkov
When injecting DRAM ECC errors (F3xBC_x8), EccVector[15:0] is a bitmask of which bits should be error injected when written to and holds the payload of 16-bit DRAM word when read, respectively. Add /sysfs members to show the DRAM ECC section/word/vector. Fail wrong injection values entered over /sysfs instead of truncating them. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
