2010-07-29CRED: Fix __task_cred()'s lockdep check and banner commentDavid Howells
Fix __task_cred()'s lockdep check by removing the following validation condition: lockdep_tasklist_lock_is_held() as commit_creds() does not take the tasklist_lock, and nor do most of the functions that call it, so this check is pointless and it can prevent detection of the RCU lock not being held if the tasklist_lock is held. Instead, add the following validation condition: task->exit_state >= 0 to permit the access if the target task is dead and therefore unable to change its own credentials. Fix __task_cred()'s comment to: (1) discard the bit that says that the caller must prevent the target task from being deleted. That shouldn't need saying. (2) Add a comment indicating the result of __task_cred() should not be passed directly to get_cred(), but rather than get_task_cred() should be used instead. Also put a note into the documentation to enforce this point there too. Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Paul E.

2010-07-24ACPI / Sleep: Allow the NVS saving to be skipped during suspend to RAMRafael J. Wysocki
Commit 2a6b69765ad794389f2fc3e14a0afa1a995221c2 (ACPI: Store NVS state even when entering suspend to RAM) caused the ACPI suspend code save the NVS area during suspend and restore it during resume unconditionally, although it is known that some systems need to use acpi_sleep=s4_nonvs for hibernation to work. To allow the affected systems to avoid saving and restoring the NVS area during suspend to RAM and resume, introduce kernel command line option acpi_sleep=nonvs and make acpi_sleep=s4_nonvs work as its alias temporarily (add acpi_sleep=s4_nonvs to the feature removal file).

2010-06-18PCI/PM: Do not use native PCIe PME by defaultRafael J. Wysocki
Commit c7f486567c1d0acd2e4166c47069835b9f75e77b (PCI PM: PCIe PME root port service driver) causes the native PCIe PME signaling to be used by default, if the BIOS allows the kernel to control the standard configuration registers of PCIe root ports. However, the native PCIe PME is coupled to the native PCIe hotplug and calling pcie_pme_acpi_setup() makes some BIOSes expect that the native PCIe hotplug will be used as well. That, in turn, causes problems to appear on systems where the PCIe hotplug driver is not loaded. The usual symptom, as reported by Jaroslav Kameník and others, is that the ACPI GPE associated with PCIe hotplug keeps firing continuously causing kacpid to take substantial percentage of CPU time. To work around this issue, change the default so that the native PCIe PME signaling is only used if directly requested with the help of the pcie_pme= command line switch. Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15924 , which is a listed regression from 2.6.33. Signed-off-by: Rafael J.

2010-05-27fs: introduce new truncate sequencenpiggin@suse.de
Introduce a new truncate calling sequence into fs/mm subsystems. Rather than setattr > vmtruncate > truncate, have filesystems call their truncate sequence from ->setattr if filesystem specific operations are required. vmtruncate is deprecated, and truncate_pagecache and inode_newsize_ok helpers introduced previously should be used. simple_setattr is introduced for simple in-ram filesystems to implement the new truncate sequence. Eventually all filesystems should be converted to implement a setattr, and the default code in notify_change should go away. simple_setsize is also introduced to perform just the ATTR_SIZE portion of simple_setattr (ie. changing i_size and trimming pagecache). To implement the new truncate sequence: - filesystem specific manipulations (eg freeing blocks) must be done in the setattr method rather than ->truncate. - vmtruncate can not be used by core code to trim blocks past i_size in the event of write failure after allocation, so this must be performed in the fs code. - convert usage of helpers block_write_begin, nobh_write_begin, cont_write_begin, and *blockdev_direct_IO* to use _newtrunc postfixed variants. These avoid calling vmtruncate to trim blocks (see previous). - inode_setattr should not be used. generic_setattr is a new function to be used to copy simple attributes into the generic inode. - make use of the better opportunity to handle errors with the new sequence. Big problem with the previous calling sequence: the filesystem is not called until i_size has already changed. This means it is not allowed to fail the call, and also it does not know what the previous i_size was. Also, generic code calling vmtruncate to truncate allocated blocks in case of error had no good way to return a meaningful error (or, for example, atomically handle block deallocation).

2010-05-27hwmon: (tmp102) Various fixesJean Delvare
Fixes from my driver review: http://lists.lm-sensors.org/pipermail/lm-sensors/2010-March/028051.html Only the small changes are in there, more important changes will come later separately as time permits. * Drop the remnants of the now gone detect function * The TMP102 has no known compatible chip * Include the right header files * Clarify why byte swapping of register values is needed * Strip resolution info bit from temperature register value * Set cache lifetime to 1/3 second * Don't arbitrarily reject limit values; clamp as needed * Make limit writing unconditional * Don't check for transaction types the driver doesn't use * Properly check for error when setting configuration * Report error on failed probe * Make the driver load automatically where needed * Various other minor fixes Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Steven King <sfking@fdwdc.com>
2010-05-27hwmon: Driver for TI TMP102 temperature sensorSteven King
Driver for the TI TMP102. The TI TMP102 is similar to the LM75. It differs from the LM75 by having a 16-bit conf register and the temp registers have a minimum resolution of 12 bits; the extended conf register can select 13-bit resolution (which this driver does) and also change the update rate (which this driver currently doesn't use). [JD: Fix tmp102_exit tag, must be __exit, not __init.] Signed-off-by: Steven King <sfking@fdwdc.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-05-27hwmon: Add description of the update_rate sysfs attributeIra W. Snyder
The update_rate attribute can be used by drivers to let userspace choose the update rate of the chip, if it is configurable. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-05-27hwmon: (lm63) Add basic support for LM64Matthew Garrett
The LM64 appears to be an LM63 with added GPIO lines. Add support for the hwmon functionality - GPIO can be added at some later stage if someone has a need for them. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

Analogous to ACPI's /sys/firmware/acpi/tables/... create /sys/firmware/sfi/tables/ The tables are primariy for the kernel, but sometimes it is useful for user-space to be able to read them. Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-05-27numa: update Documentation/vm/numa, add memoryless node infoLee Schermerhorn
Kamezawa Hiroyuki requested documentation for the numa_mem_id() and slab related changes. He suggested Documentation/vm/numa for this documentation. Looking at this file, it seems to me to be hopelessly out of date relative to current Linux NUMA support. At the risk of going down a rathole, I have made an attempt to rewrite the doc at a slightly higher level [I think] and provide pointers to other in-tree documents and out-of-tree man pages that cover the details. Let the games begin.
