2014-06-10x86: intel-mid: add watchdog platform code for MerrifieldDavid Cohen2-0/+73
This patch adds platform code for Intel Merrifield. Since the watchdog is not part of SFI table, we have no other option but to manually register watchdog's platform device (argh!).

2014-06-10booke/watchdog: refine and clean up the codesTang Yuantian2-45/+33
Basically, this patch does the following: 1. Move the codes of parsing boot parameters from setup-common.c to driver. In this way, code reader can know directly that there are boot parameters that can change the timeout. 2. Make boot parameter 'booke_wdt_period' effective. currently, when driver is loaded, default timeout is always being used in stead of booke_wdt_period. 3. Wrap up the watchdog timeout in device struct and clean up unnecessary codes.

2014-06-10watchdog: iop_wdt only builds for mach-iop13xxArnd Bergmann1-1/+1
All three iop variants we support in Linux (iop32x, iop33x and iop13xx) seem to have support for the watchdog hardware, but this driver fails to build for the first two of these because it uses the IOP13XX_WDTCR_IB_RESET macro that is only defined for iop13xx. This clarifies the dependency in Kconfig to avoid randconfig build errors. It is unlikely that anyone will ever miss support for this driver on the ancient iop3xx platforms, so we don't need to bother trying to fix it properly.

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.

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.

2014-06-10raid5: speedup sync_request processingEivind Sarto1-1/+1
The raid5 sync_request() processing calls handle_stripe() within the context of the resync-thread. The resync-thread issues the first set of read requests and this adds execution latency and slows down the scheduling of the next sync_request(). The current rebuild/resync speed of raid5 is not much faster than what rotational HDDs can sustain. Testing the following patch on a 6-drive array, I can increase the rebuild speed from 100 MB/s to 175 MB/s. The sync_request() now just sets STRIPE_HANDLE and releases the stripe. This creates some more parallelism between the resync-thread and raid5 kernel daemon. Signed-off-by: Eivind Sarto <[email protected]> Signed-off-by: NeilBrown <[email protected]>

2014-06-09Btrfs: make fsync work after cloning into a fileFilipe Manana4-38/+155
When cloning into a file, we were correctly replacing the extent items in the target range and removing the extent maps. However we weren't replacing the extent maps with new ones that point to the new extents - as a consequence, an incremental fsync (when the inode doesn't have the full sync flag) was a NOOP, since it relies on the existence of extent maps in the modified list of the inode's extent map tree, which was empty. Therefore add new extent maps to reflect the target clone range. A test case for xfstests follows.
