* hwmon: (coretemp) Fix TjMax detection for older CPUsGuenter Roeck2011-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit a321cedb12904114e2ba5041a3673ca24deb09c9 excludes CPU models 0xe, 0xf, 0x16, and 0x1a from TjMax temperature adjustment, even though several of those CPUs are known to have TiMax other than 100 degrees C, and even though the code in adjust_tjmax() explicitly handles those CPUs and points to a Web document listing several of the affected CPU IDs. Reinstate original TjMax adjustment if TjMax can not be determined using the IA32_TEMPERATURE_TARGET register. https://bugzilla.kernel.org/show_bug.cgi?id=32582 Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com> Cc: Huaxu Wan <huaxu.wan@linux.intel.com> Cc: Carsten Emde <C.Emde@osadl.org> Cc: Valdis Kletnieks <valdis.kletnieks@vt.edu> Cc: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Cc: Yong Wang <yong.y.wang@linux.intel.com> Cc: Rudolf Marek <r.marek@assembler.cz> Cc: Fenghua Yu <fenghua.yu@intel.com> Tested-by: Jean Delvare <khali@linux-fr.org> Acked-by: Jean Delvare <khali@linux-fr.org> Acked-by: Fenghua Yu <fenghua.yu@intel.com> Cc: <stable@kernel.org> # .35.x .36.x .37.x .38.x .39.x
* hwmon: (coretemp) Relax target temperature range checkJean Delvare2011-06-01
| | | | | | | | | | | | The current temperature range check of MSR_IA32_TEMPERATURE_TARGET seems too strict to me, some TjMax values documented in Documentation/hwmon/coretemp wouldn't pass. Relax the check so that all the documented values pass.

| * eCryptfs: Cleanup and optimize ecryptfs_lookup_interpose()Tyler Hicks2011-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ecryptfs_lookup_interpose() has turned into spaghetti code over the years. This is an effort to clean it up. - Shorten overly descriptive variable names such as ecryptfs_dentry - Simplify gotos and error paths - Create helper function for reading plaintext i_size from metadata It also includes an optimization when reading i_size from the metadata. A complete page-sized kmem_cache_alloc() was being done to read in 16 bytes of metadata. The buffer for that is now statically declared. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | Instead of having the calling functions translate the true/false return code to either 0 or -EINVAL, have contains_ecryptfs_marker() return 0 or -EINVAL so that the calling functions can just reuse the return code. Also, rename the function to ecryptfs_validate_marker() to avoid callers mistakenly thinking that it returns true/false codes. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>

| * eCryptfs: Cleanup inode initialization codeTyler Hicks2011-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eCryptfs inode get, initialization, and dentry interposition code has two separate paths. One is for when dentry interposition is needed after doing things like a mkdir in the lower filesystem and the other is needed after a lookup. Unlocking new inodes and doing a d_add() needs to happen at different times, depending on which type of dentry interposing is being done. This patch cleans up the inode get and initialization code paths and splits them up so that the locking and d_add() differences mentioned above can be handled appropriately in a later patch.

When IO is done if all was well the io_state is freed. (as today). If the I/O has ended with an error, the io_state is queued on a per-layout err_list. When eventually encode_layoutreturn() is called, each error is properly encoded on the XDR buffer and only then the io_state is removed from err_list and de-allocated. It is up to the io_engine to fill in the segment that fault and the type of osd_error that occurred. By calling objlayout_io_set_result() for each failing device.

This is convenient, but makes certain kinds of failures hard for a user to detect. For example, if the client falls back on 4.0, or falls back to MDS IO because the user didn't connect to the right iscsi disks before mounting, the only symptoms may be reduced performance, which may not be noticed till long after the actual failure, and may be difficult for a user to diagnose. However, such "failures" may also be perfectly normal in some cases, so we don't want to spam the system logs with them. One approach would be to put some more information into /proc/self/mountstats.

| * | NFSv4.1: purge deviceid cache on nfs_free_clientBenny Halevy2011-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the pnfs_layoutdriver_type both as a qualifier for the deviceid, distinguishing deviceid from different layout types on the server, and for freeing the layout-driver allocated structure containing the nfs4_deviceid_node. [BUG in _deviceid_purge_client] [layout_driver MUST set free_deviceid_node if using dev-cache] [let ver < 4.1 compile] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> [removed EXPORT_SYMBOL_GPL(nfs4_deviceid_purge_client)] Signed-off-by: Benny Halevy <bhalevy@panasas.com>
| * | NFSv4.1: make deviceid cache globalBenny Halevy2011-05-29

| * | pnfs: resolve header dependency in pnfs.hBenny Halevy2011-05-29
| | | | | | | | | | | | | | | | | | | | | Some definitions in the header file depend on nfs_fs.h so pnfs.h can't be included independently. Signed-off-by: Benny Halevy <bhalevy@panasas.com>
| * | NFSv4.1: use struct nfs_client to qualify deviceidBenny Halevy2011-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | deviceids are unique per server, per layout type. Therefore, in the global cache in the files layout driver deviceids from different servers may clash so we need to qualify them with a struct nfs_client that represents the nfs server that returned the deviceid. Introduced in 2.6.39 commit ea8eecdd "NFSv4.1 move deviceid cache to filelayout driver" Signed-off-by: Benny Halevy <bhalevy@panasas.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had a few drivers move from arch/arm into drivers/gpio, but they don't actually compile without the ARM platform headers etc. As a result they were messing up allyesconfig on x86.

| | * | msi-laptop: fix section mismatch in reference from the function ↵Lee, Chun-Yi2011-05-27

The problem is the load_scm_model_init() calls msi_laptop_input_setup() which is an __init function, but load_scm_model_init() lacks a __init annotation. This patch add __init on load_scm_model_init() to avoid warning message.
