2015-06-29agp/intel: Fix typo in needs_ilk_vtd_wa()Chris Wilson
In needs_ilk_vtd_wa(), we pass in the GPU device but compared it against the ids for the mobile GPU and the mobile host bridge. That latter is impossible and so likely was just a typo for the desktop GPU device id (which is also buggy).

2015-06-10random: Remove kernel blocking APIHerbert Xu
This patch removes the kernel blocking API as it has been completely replaced by the callback API. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-10random: Add callback API for random pool readinessHerbert Xu
The get_blocking_random_bytes API is broken because the wait can be arbitrarily long (potentially forever) so there is no safe way of calling it from within the kernel. This patch replaces it with a callback API instead. The callback is invoked potentially from interrupt context so the user needs to schedule their own work thread if necessary. In addition to adding callbacks, they can also be removed as otherwise this opens up a way for user-space to allocate kernel memory with no bound (by opening algif_rng descriptors and then closing them).

2015-06-02writeback: separate out include/linux/backing-dev-defs.hTejun Heo
With the planned cgroup writeback support, backing-dev related declarations will be more widely used across block and cgroup; unfortunately, including backing-dev.h from include/linux/blkdev.h makes cyclic include dependency quite likely. This patch separates out backing-dev-defs.h which only has the essential definitions and updates blkdev.h to include it. c files which need access to more backing-dev details now include backing-dev.h directly. This takes backing-dev.h off the common include dependency chain making it a lot easier to use it across block and cgroup. v2: fs/fat build failure fixed.

2015-06-01char: misc: restore MISC_DYNAMIC_MINOR on device_create() failureVladimir Zapolskiy
On attempt to register a dynamic minor misc device its minor number is updated to a virtual minor number prior to device_create() call, however on error path misc->minor == MISC_DYNAMIC_MINOR is not restored. Following the rule of thumb that a function returning an error must not change the state of the caller, assign MISC_DYNAMIC_MINOR back. The problem is met in a sutuation, when subsys_initcall(misc_init) is not yet called and misc_class is not created, but misc_register() modifies statically defined ".minor = MISC_DYNAMIC_MINOR", therefore implicitly changing the client's logic on next attempt (e.g. retrying from deferred list) to register a misc device, whose minor number is converted from dynamic to some unknown static one.

2015-05-05ipmi: Fix multi-part message handlingCorey Minyard
Lots of little fixes for multi-part messages: The values was not being re-initialized, if something went wrong handling a multi-part message and it got left in a bad state, it might be an issue. The commands were not correct when issuing multi-part reads, the code was not passing in the proper value for commands. Also clean up some minor formatting issues. Get the block number from the right location, limit the maximum send message size to 63 bytes and explain why, and fix some minor sylistic issues. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2015-05-05ipmi: Add alert handling to SSIFCorey Minyard
The SSIF interface can optionally have an SMBus alert come in when data is ready. Unfortunately, the IPMI spec gives wiggle room to the implementer to allow them to always have the alert enabled, even if the driver doesn't enable it. So implement alerts. If you don't in this situation, the SMBus alert handling will constantly complain. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2015-05-05ipmi: Fix a problem that messages are not issued in run_to_completion modeHidehiro Kawai
start_next_msg() issues a message placed in smi_info->waiting_msg if it is non-NULL. However, sender() sets a message to smi_info->curr_msg and NULL to smi_info->waiting_msg in the context of run_to_completion mode. As the result, it leads an infinite loop by waiting the completion of unissued message when leaving dying message after kernel panic. sender() should set the message to smi_info->waiting_msg not curr_msg.

2015-05-05ipmi: Remove incorrect use of seq_has_overflowedJoe Perches
commit d6c5dc18d863 ("ipmi: Remove uses of return value of seq_printf") incorrectly changed the return value of various proc_show functions to use seq_has_overflowed(). These functions should return 0 on completion rather than 1/true on overflow. 1 is the same as #define SEQ_SKIP which would cause the output to not be emitted (skipped) instead. This is a logical defect only as the length of these outputs are all smaller than the initial allocation done by the seq filesystem.

2015-04-15xenbus_client: Extend interface to support multi-page ringWei Liu
Originally Xen PV drivers only use single-page ring to pass along information. This might limit the throughput between frontend and backend. The patch extends Xenbus driver to support multi-page ring, which in general should improve throughput if ring is the bottleneck. Changes to various frontend / backend to adapt to the new interface are also included. Affected Xen drivers: * blkfront/back * netfront/back * pcifront/back * scsifront/back * vtpmfront The interface is documented, as before, in xenbus_client.c.
