2010-07-28ecryptfs: Bugfix for error related to ecryptfs_hash_bucketsAndre Osterhues1-8/+9
The function ecryptfs_uid_hash wrongly assumes that the second parameter to hash_long() is the number of hash buckets instead of the number of hash bits. This patch fixes that and renames the variable ecryptfs_hash_buckets to ecryptfs_hash_bits to make it clearer.

2010-07-28x86,kgdb: Fix hw breakpoint regressionJason Wessel1-2/+7
HW breakpoints events stopped working correctly with kgdb as a result of commit: 018cbffe6819f6f8db20a0a3acd9bab9bfd667e4 (Merge commit 'v2.6.33' into perf/core). The regression occurred because the behavior changed for setting NOTIFY_STOP as the return value to the die notifier if the breakpoint was known to the HW breakpoint API. Because kgdb is using the HW breakpoint API to register HW breakpoints slots, it must also now implement the overflow_handler call back else kgdb does not get to see the events from the die notifier. The kgdb_ll_trap function will be changed to be general purpose code which can allow an easy way to implement the hw_breakpoint API overflow call back.

2010-07-28GFS2: Use kmalloc when possible for ->readdir()Steven Whitehouse1-6/+25
If we don't need a huge amount of memory in ->readdir() then we can use kmalloc rather than vmalloc to allocate it. This should cut down on the greater overheads associated with vmalloc for smaller directories. We may be able to eliminate vmalloc entirely at some stage, but this is easy to do right away. Also using GFP_NOFS to avoid any issues wrt to deleting inodes while under a glock, and suggestion from Linus to factor out the alloc/dealloc. I've given this a test with a variety of different sized directories and it seems to work ok.

2010-07-28davinci: da850/omap-l138 evm: account for DEFDCDC{2,3} being tied highSekhar Nori1-0/+8
Per the da850/omap-l138 Beta EVM SOM schematic, the DEFDCDC2 and DEFDCDC3 lines are tied high. This leads to a 3.3V IO and 1.2V CVDD voltage. Pass the right platform data to the TPS6507x driver so it can operate on the DEFDCDC{2,3}_HIGH register to read and change voltage levels.

2010-07-28regulator: tps6507x: allow driver to use DEFDCDC{2,3}_HIGH registerAnuj Aggarwal2-7/+61
Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> In TPS6507x, depending on the status of DEFDCDC{2,3} pin either DEFDCDC{2,3}_LOW or DEFDCDC{2,3}_HIGH register needs to be read or programmed to change the output voltage. The current driver assumes DEFDCDC{2,3} pins are always tied low and thus operates only on DEFDCDC{2,3}_LOW register. This need not always be the case (as is found on OMAP-L138 EVM). Unfortunately, software cannot read the status of DEFDCDC{2,3} pins. So, this information is passed through platform data depending on how the board is wired.

2010-07-27perf, powerpc: Use perf_sample_data_init() for the FSL codePeter Zijlstra1-3/+3
We should use perf_sample_data_init() to initialize struct perf_sample_data. As explained in the description of commit dc1d628a ("perf: Provide generic perf_sample_data initialization"), it is possible for userspace to get the kernel to dereference data.raw, so if it is not initialized, that means that unprivileged userspace can possibly oops the kernel. Using perf_sample_data_init makes sure it gets initialized to NULL. This conversion should have been included in commit dc1d628a, but it got missed.

The PCC cpufreq driver unmaps the mailbox address range if any CPUs fail to initialise, but doesn't do anything to remove the registered CPUs from the cpufreq core resulting in failures further down the line. We're better off simply returning a failure - the cpufreq core will unregister us cleanly if we end up with no successfully registered CPUs. Tidy up the failure path and also add a sanity check to ensure that the firmware gives us a realistic frequency - the core deals badly with that being set to 0.

2010-07-26[CPUFREQ] pcc driver should check for pcch method before calling _OSCMatthew Garrett1-1/+5
The pcc specification documents an _OSC method that's incompatible with the one defined as part of the ACPI spec. This shouldn't be a problem as both are supposed to be guarded with a UUID. Unfortunately approximately nobody (including HP, who wrote this spec) properly check the UUID on entry to the _OSC call. Right now this could result in surprising behaviour if the pcc driver performs an _OSC call on a machine that doesn't implement the pcc specification. Check whether the PCCH method exists first in order to reduce this probability.

2010-07-26sysfs: Don't allow the creation of symlinks we can't removeEric W. Biederman1-5/+18
Recently my tagged sysfs support revealed a flaw in the device core that a few rare drivers are running into such that we don't always put network devices in a class subdirectory named net/. Since we are not creating the class directory the network devices wind up in a non-tagged directory, but the symlinks to the network devices from /sys/class/net are in a tagged directory. All of which works until we go to remove or rename the symlink. When we remove or rename a symlink we look in the namespace of the target of the symlink. Since the target of the symlink is in a non-tagged sysfs directory we don't have a namespace to look in, and we fail to remove the symlink. Detect this problem up front and simply don't create symlinks we won't be able to remove later. This prevents symlink leakage and fails in a much clearer and more understandable way.

2010-07-26USB: usb-storage: fix initializations of urb fieldsBob Copeland1-3/+1
Commit 0ede76fcec5415ef82a423a95120286895822e2d, "USB: remove uses of URB_NO_SETUP_DMA_MAP" introduced a regression by inadvertantly removing initialization of the transfer flags. This caused initialization failures in the ums-karma driver. Fix the regression by zeroing it. While at it, as Alan Stern points out, the initializers for actual_length and status are handled by the core and error_count only matters for isochronous urbs, so they don't need to be set here. Remove them. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-07-26USB: xhci: Set Mult field in endpoint context correctly.Sarah Sharp1-2/+3
The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has different meanings, depending on the endpoint type. If the endpoint is isochronous, the bmAttributes field is the maximum number of packets within a service interval that this endpoint supports. If the endpoint is bulk, it's the number of stream IDs this endpoint supports. Only set the Mult field of the xHCI endpoint context using the bmAttributes field if the endpoint is isochronous, and the device is a SuperSpeed device.

2010-07-26USB: adds Artisman USB dongle to list of quirky devicesPaul Mortier1-0/+4
When an attempt is made to read the interface strings of the Artisman Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written to the dmesg log (uhci_result_common: failed with status 440000) and the dongle resets itself, resulting in a disconnect/reconnect loop. Adding the dongle to the list of devices in quirks.c, with the same quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D joystick, stops the device from resetting and allows it to be used with no problems.

2010-07-26USB: xhci: Set EP0 dequeue ptr after reset of configured device.Sarah Sharp3-0/+25
When a configured device is reset, the control endpoint's ring is reused. If control transfers to the device were issued before the device is reset, the dequeue pointer will be somewhere in the middle of the ring. If the device is then issued an address with the set address command, the xHCI driver must provide a valid input context for control endpoint zero. The original code would give the hardware the original input context, which had a dequeue pointer set to the top of the ring. This would cause the host to re-execute any control transfers until it reached the ring's enqueue pointer. When issuing a set address command for a device that has just been configured and then reset, use the control endpoint's enqueue pointer as the hardware's dequeue pointer. Assumption: All control transfers will be completed or cancelled before the set address command is issued to the device. If there are any outstanding control transfers, this code will not work.
