2014-06-10watchdog: ath79_wdt: avoid spurious restarts on AR934xGabor Juhos1-0/+10
On some AR934x based systems, where the frequency of the AHB bus is relatively high, the built-in watchdog causes a spurious restart when it gets enabled. The possible cause of these restarts is that the timeout value written into the TIMER register does not reaches the hardware in time. Add an explicit delay into the ath79_wdt_enable function to avoid the spurious restarts.

With commit 762380ad9322 added support for chunk sizes and no merging across them, it broke the rule of always allowing adding of a single page to an empty bio. So relax the restriction a bit to allow for that, similarly to what we have always done. This fixes a crash with mkfs.xfs and 512b sector sizes on NVMe.

2014-06-10RDMA/core: Add support for iWARP Port Mapper user space serviceTatyana Nikolova9-6/+1865
This patch adds iWARP Port Mapper (IWPM) Version 2 support. The iWARP Port Mapper implementation is based on the port mapper specification section in the Sockets Direct Protocol paper - http://www.rdmaconsortium.org/home/draft-pinkerton-iwarp-sdp-v1.0.pdf Existing iWARP RDMA providers use the same IP address as the native TCP/IP stack when creating RDMA connections. They need a mechanism to claim the TCP ports used for RDMA connections to prevent TCP port collisions when other host applications use TCP ports. The iWARP Port Mapper provides a standard mechanism to accomplish this. Without this service it is possible for RDMA application to bind/listen on the same port which is already being used by native TCP host application. If that happens the incoming TCP connection data can be passed to the RDMA stack with error. The iWARP Port Mapper solution doesn't contain any changes to the existing network stack in the kernel space. All the changes are contained with the infiniband tree and also in user space. The iWARP Port Mapper service is implemented as a user space daemon process. Source for the IWPM service is located at http://git.openfabrics.org/git?p=~tnikolova/libiwpm-1.0.0/.git;a=summary The iWARP driver (port mapper client) sends to the IWPM service the local IP address and TCP port it has received from the RDMA application, when starting a connection. The IWPM service performs a socket bind from user space to get an available TCP port, called a mapped port, and communicates it back to the client. In that sense, the IWPM service is used to map the TCP port, which the RDMA application uses to any port available from the host TCP port space. The mapped ports are used in iWARP RDMA connections to avoid collisions with native TCP stack which is aware that these ports are taken. When an RDMA connection using a mapped port is terminated, the client notifies the IWPM service, which then releases the TCP port. The message exchange between the IWPM service and the iWARP drivers (between user space and kernel space) is implemented using netlink sockets. 1) Netlink interface functions are added: ibnl_unicast() and ibnl_mulitcast() for sending netlink messages to user space 2) The signature of the existing ibnl_put_msg() is changed to be more generic 3) Two netlink clients are added: RDMA_NL_NES, RDMA_NL_C4IW corresponding to the two iWarp drivers - nes and cxgb4 which use the IWPM service 4) Enums are added to enumerate the attributes in the netlink messages, which are exchanged between the user space IWPM service and the iWARP drivers Signed-off-by: Tatyana Nikolova <[email protected]> Signed-off-by: Steve Wise <[email protected]> Reviewed-by: PJ Waskiewicz <[email protected]> [ Fold in range checking fixes and nlh_next removal as suggested by Dan Carpenter and Steve Wise.

The freeing of an instance, if max data is configured, there will be per cpu data structures created. But these are not freed when the instance is deleted, which causes a memory leak. A new helper function is added that frees the individual buffers within a trace array, instead of duplicating the code. This way changes made for one are applied to the other (normal buffer vs max buffer).

2014-06-10ring-buffer: Check if buffer exists before pollingSteven Rostedt (Red Hat)3-8/+21
The per_cpu buffers are created one per possible CPU. But these do not mean that those CPUs are online, nor do they even exist. With the addition of the ring buffer polling, it assumes that the caller polls on an existing buffer. But this is not the case if the user reads trace_pipe from a CPU that does not exist, and this causes the kernel to crash. Simple fix is to check the cpu against buffer bitmask against to see if the buffer was allocated or not and return -ENODEV if it is not. More updates were done to pass the -ENODEV back up to userspace.

2014-06-10scripts: objdiff: support directories for the augument of record commandMasahiro Yamada1-11/+22
For example, $ scripts/objdiff record init drivers/usb disassembles all the objects under init and drivers/usb directories. This feature would be useful when we change various files under the specific directory.

2014-06-10scripts: objdiff: change the extension of disassembly from .o to .disMasahiro Yamada1-2/+3
Prior to this commit, the command "scripts/objdiff record path/to/*.o" disassembled the given object into ".tmp_objdiff/path/to/*.o" file. The problem here is that recorded disassemblies are lost if we run "make clean" because it removes all the *.o files. Disassembled code should be dumped into *.dis instead of *.o files.

2014-06-10scripts: objdiff: improve path flexibility for record commandMasahiro Yamada1-6/+16
Prior to this commit, scripts/objdiff expected to be run at the top directory and only the relative path of objects. This commit provides more flexibility in terms of object path: [1] scripts/objdiff can be run in any directory For example, $ scripts/objdiff record init/main.o and $ cd init; ../scripts/objdiff record main.o produce the same result. [2] Support absolute path for objects $ scripts/objdiff record /home/foo/bar/linux/init/main.o work as well.

2014-06-10scripts: objdiff: get the path to .tmp_objdiff more simplyMasahiro Yamada1-7/+5
This commit is a minor refactoring. Temporary files for objdiff are stored in .tmp_objdiff directory which is located at the top directory. To get the path to this directory, SRCTREE=`git rev-parse --show-toplevel` TMPD=$SRCTREE/.tmp_objdiff seems easier to understand than GIT_DIR=`git rev-parse --git-dir` TMPD=${GIT_DIR%git}tmp_objdiff Besides, it is not always necessary to create .tmp_objdiff dicrectory. It should be created only for "record" command. Signed-off-by: Masahiro Yamada <[email protected]> Acked-by: Jason Cooper <[email protected]> Signed-off-by: Michal Marek <[email protected]>
2014-06-10deb-pkg: Add automatic support for s390x architectureBen Hutchings1-1/+1
The Debian s390x architecture has 64-bit userland whereas s390 has 32-bit userland. A 64-bit kernel can be used with either. Now that Debian supports multiarch and officially supports s390x, it makes more sense to assign a 64-bit kernel package to s390x.

2014-06-10drm/nouveau/kms/nv04-nv40: fix pageflip events via special case.Mario Kleiner1-2/+8
Cards with nv04 display engine can't reliably use vblank counts and timestamps computed via drm_handle_vblank(), as the function gets invoked after sending the pageflip events. Fix this by defaulting to the old crtcid = -1 fallback path on <= NV-50 cards, and only using the precise path on NV-50 and later.

2014-06-10drm/nv50-/mc: fix kms pageflip events by reordering irq handling order.Mario Kleiner3-3/+3
Whenever a single nouveau_mc_intr() main gpu irq-handler invocation was responsible for calling both, the vblank-irq handler (display engine irq) and kms-pageflip completion handler (from fifo irq), the order of invocation was wrong. nouveau_finish_flip() was called before drm_handle_vblank() for the vblank of pageflip completion, so the emitted pageflip event contained stale vblank count and timestamp from previous vblank. This caused failure in userspace to timestamp properly. Reorder order of invocation of engine irq handlers: Put NVDEV_ENGINE_DISP always on top, and thereby before NVDEV_ENGINE_FIFO, so that drm_handle_vblank() gets called to update vblank timestamps and count before potential pageflip events make use of that information. This works on nv-50 and later, where kms-pageflip completion triggers an irq either after a separate vblank irq, or both pageflip and vblank trigger one common irq invocation, but never before vblank irqs. v2 (Ben): - removed mods for nv04-nv40, it doesn't help there anyway - this is considered a hack, and a better solution should be found Signed-off-by: Mario Kleiner <[email protected]> Signed-off-by: Ben Skeggs <[email protected]> Cc: <[email protected]> # 3.13+
2014-06-10drm/nouveau/disp/nv04-nv40: abort scanoutpos query on vga analog.Mario Kleiner1-0/+8
nv04_disp_scanoutpos() must abort to trigger simple timestamping fallback if vtotal/htotal regs return zero. This happens if the output isn't a digital output, but a vga analog output, as the regs don't get initialized in that case. Fixes timestamping failure on nv-40 and earlier with vga output.
