2015-04-24ACPI / scan: Add a scan handler for PRP0001Rafael J. Wysocki1-5/+28
If the special PRP0001 device ID is present in the given device's list of ACPI/PNP IDs and the device has a valid "compatible" property in the _DSD, it should be enumerated using the default mechanism, unless some scan handlers match the IDs preceding PRP0001 in the device's list of ACPI/PNP IDs. In addition to that, no scan handlers matching the IDs following PRP0001 in that list should be attached to the device. To make that happen, define a scan handler that will match PRP0001 and trigger the default enumeration for the matching devices if the "compatible" property is present for them. Since that requires the check for platform_id and device->handler to be removed from acpi_default_enumeration(), move the fallback invocation of acpi_default_enumeration() to acpi_bus_attach() (after it's checked if there's a matching ACPI driver for the device), which is a better place to call it, and do the platform_id check in there too (device->handler is guaranteed to be unset at the point where the function is looking for a matching ACPI driver).

2015-04-23drm/i915: Workaround to avoid lite restore with HEAD==TAILMichel Thierry2-2/+36
WaIdleLiteRestore is an execlists-only workaround, and requires the driver to ensure that any context always has HEAD!=TAIL when attempting lite restore. Add two extra MI_NOOP instructions at the end of each request, but keep the requests tail pointing before the MI_NOOPs. We may not need to executed them, and this is why request->tail is sampled before adding these extra instructions. If we submit a context to the ELSP which has previously been submitted, move the tail pointer past the MI_NOOPs. This ensures HEAD!=TAIL. v2: Move overallocation to gen8_emit_request, and added note about sampling request->tail in commit message (Chris). v3: Remove redundant request->tail assignment in __i915_add_request, in lrc mode this is already set in execlists_context_queue. Do not add wa implementation details inside gem (Chris). v4: Apply the wa whenever the req has been resubmitted and update comment (Chris).

2015-04-23drm/i915: cope with large i2c transfersDmitry Torokhov2-10/+57
The hardware, according to the specs, is limited to 256 byte transfers, and current driver has no protections in case users attempt to do larger transfers. The code will just stomp over status register and mayhem ensues. Let's split larger transfers into digestable chunks.

2015-04-23Revert "nfs: replace nfs_add_stats with nfs_inc_stats when add one"Nicolas Iooss2-2/+2
This reverts commit 5a254d08b086d80cbead2ebcee6d2a4b3a15587a. Since commit 5a254d08b086 ("nfs: replace nfs_add_stats with nfs_inc_stats when add one"), nfs_readpage and nfs_do_writepage use nfs_inc_stats to increment NFSIOS_READPAGES and NFSIOS_WRITEPAGES instead of nfs_add_stats. However nfs_inc_stats does not do the same thing as nfs_add_stats with value 1 because these functions work on distinct stats: nfs_inc_stats increments stats from "enum nfs_stat_eventcounters" (in server->io_stats->events) and nfs_add_stats those from "enum nfs_stat_bytecounters" (in server->io_stats->bytes).

2015-04-23nfs: Fetch MOUNTED_ON_FILEID when updating an inodeAnna Schumaker2-2/+16
2ef47eb1 (NFS: Fix use of nfs_attr_use_mounted_on_fileid()) was a good start to fixing a circular directory structure warning for NFS v4 "junctioned" mountpoints. Unfortunately, further testing continued to generate this error. My server is configured like this: anna@nfsd ~ % df Filesystem Size Used Avail Use% Mounted on /dev/vda1 9.1G 2.0G 6.5G 24% / /dev/vdc1 1014M 33M 982M 4% /exports /dev/vdc2 1014M 33M 982M 4% /exports/vol1 /dev/vdc3 1014M 33M 982M 4% /exports/vol1/vol2 anna@nfsd ~ % cat /etc/exports /exports/ *(rw,async,no_subtree_check,no_root_squash) /exports/vol1/ *(rw,async,no_subtree_check,no_root_squash) /exports/vol1/vol2 *(rw,async,no_subtree_check,no_root_squash) I've been running chown across the entire mountpoint twice in a row to hit this problem. The first run succeeds, but the second one fails with the circular directory warning along with: anna@client ~ % dmesg [Apr 3 14:28] NFS: server 192.168.100.204 error: fileid changed fsid 0:39: expected fileid 0x100080, got 0x80 WHere 0x80 is the mountpoint's fileid and 0x100080 is the mounted-on fileid.

2015-04-23sunrpc: make debugfs file creation failure non-fatalJeff Layton5-47/+41
v2: gracefully handle the case where some dentry pointers end up NULL and be more dilligent about zeroing out dentry pointers We currently have a problem that SELinux policy is being enforced when creating debugfs files. If a debugfs file is created as a side effect of doing some syscall, then that creation can fail if the SELinux policy for that process prevents it. This seems wrong. We don't do that for files under /proc, for instance, so Bruce has proposed a patch to fix that. While discussing that patch however, Greg K.H. stated: "No kernel code should care / fail if a debugfs function fails, so please fix up the sunrpc code first." This patch converts all of the sunrpc debugfs setup code to be void return functins, and the callers to not look for errors from those functions. This should allow rpc_clnt and rpc_xprt creation to work, even if the kernel fails to create debugfs files for some reason. Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: "J.

2015-04-23nfs: fix high load average due to callback thread sleepingJeff Layton1-3/+3
Chuck pointed out a problem that crept in with commit 6ffa30d3f734 (nfs: don't call blocking operations while !TASK_RUNNING). Linux counts tasks in uninterruptible sleep against the load average, so this caused the system's load average to be pinned at at least 1 when there was a NFSv4.1+ mount active. Not a huge problem, but it's probably worth fixing before we get too many complaints about it. This patch converts the code back to use TASK_INTERRUPTIBLE sleep, simply has it flush any signals on each loop iteration. In practice no one should really be signalling this thread at all, so I think this is reasonably safe. With this change, there's also no need to game the hung task watchdog so we can also convert the schedule_timeout call back to a normal schedule.

2015-04-23i2c: Mark adapter devices with pm_runtime_no_callbacksCharles Keepax1-0/+2
Commit 523c5b89640e ("i2c: Remove support for legacy PM") removed the PM ops from the bus type, which causes the pm operations on the s3c2410 adapter device to fail (-ENOSUPP in rpm_callback). The adapter device doesn't get bound to a driver and as such can't have its own pm_runtime callbacks. Previously this was fine as the bus callbacks would have been used, but now this can cause devices which use PM runtime and are attached over I2C to fail to resume. This commit fixes this issue by marking all adapter devices with pm_runtime_no_callbacks, since they can't have any.

The latter causes the following build failure. drivers/tty/serial/8250/8250_core.c: In function 'mem32be_serial_out': drivers/tty/serial/8250/8250_core.c:456:2: error: implicit declaration of function 'iowrite32be' drivers/tty/serial/8250/8250_core.c: In function 'mem32be_serial_in': drivers/tty/serial/8250/8250_core.c:462:2: error: implicit declaration of function 'ioread32be' Cc: Kevin Cernekee <cernekee@gmail.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Fixes: c627f2ceb692 ("serial: 8250: Add support for big-endian MMIO accesses") Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rob Herring <robh@kernel.org>
