2008-02-08dm: refactor dm_suspend completion waitMilan Broz
Move completion wait to separate function Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm: split dm_suspend io_lock hold into twoMilan Broz
Change io_locking to allow processing flush in separate thread. Because we have DMF_BLOCK_IO already set, any possible new ios are queued in dm_requests now. In the case of interrupting previous wait there can be more ios queued (we unlocked io_lock for a while) but this is safe.

2008-02-08dm: tidy dm_suspendMilan Broz
Tidy dm_suspend function - change return value logic in dm_suspend - use atomic_read only once. - move DMF_BLOCK_IO clearing into one place Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm: refactor deferred bio_list processingMilan Broz
Refactor deferred bio_list processing. - use separate _merge_pushback_list function - move deferred bio list pick up to flush function - use bio_list_pop instead of bio_list_get - simplify noflush flag use No real functional change in this patch. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm: tidy alloc_dev labelsMilan Broz
Tidy labels in alloc_dev to make later patches more clear. No functional change in this patch. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>

2008-02-08dm: convert suspend_lock semaphore to mutexDaniel Walker
Replace semaphore with mutex. Signed-off-by: Daniel Walker <dwalker@mvista.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm snapshot: use rounddown_pow_of_twoRobert P. J. Day
Since the source file already includes the log2.h header file, it seems pointless to re-invent the necessary routine. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm: table remove unused totalJun'ichi Nomura
"total = 0" does nothing. Signed-off-by: Jun'ichi Nomura <j-nomura@ce.jp.nec.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm: table use list_for_eachPaul Jimenez
This patch is some minor janitorish cleanup, using some macros from linux/list.h (already #included via dm.h) to improve readability. Signed-off-by: Paul Jimenez <pj@place.org> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm ioctl: move compat codeMilan Broz
Move compat_ioctl handling into dm-ioctl.c. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm ioctl: remove lock_kernelAlasdair G Kergon
Remove lock_kernel() from the device-mapper ioctls - there should be sufficient internal locking already where required. Also remove some superfluous casts. Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm: mark function lists staticAlasdair G Kergon
Add a couple of statics. Signed-off-by: Alasdair G Kergon <agk@redhat.com>

Add memory barrier to fix atomic_read of pending value. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-07hwmon: (lm80) Add individual alarm filesJean Delvare
The new libsensors needs these individual alarm files. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (lm80) De-macro the sysfs callbacksJean Delvare
Use standard dynamic sysfs callbacks instead of macro-generated functions. This makes the code more readable, and the binary smaller (by about 34%). As a side note, another benefit of this type of cleanup is that they shrink the build time. For example, this cleanup saves about 29% of the lm80 driver build time. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (lm80) Various cleanupsJean Delvare
* Drop trailing whitespace * Fold a long line * Rename new_client to client * Drop redundant initializations to 0 * Drop bogus comment Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (w83627hf) Refactor beep enable handlingJean Delvare
We can handle the beep enable bit as any other beep mask bit for slightly smaller code. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (w83627hf) Add individual alarm and beep filesJean Delvare
The new libsensors needs these individual alarm and beep files. The code was copied from the w83781d driver. I've tested the alarm files on a W83627THF. I couldn't test the beep files as the system in question doesn't have a speaker. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (w83627hf) Enable VBAT monitoringJean Delvare
If VBAT monitoring is disabled, enable it. Bug reported on the lm-sensors trac system: http://lm-sensors.org/ticket/2282 This is the exact same patch that was applied to the w83627ehf driver 6 months ago. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (w83627ehf) The W83627DHG has 8 VID pinsJean Delvare
While the W83627EHF/EHG has only 6 VID pins, the W83627DHG has 8 VID pins, to support VRD 11.0. Add support for this. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (asb100) Add individual alarm filesJean Delvare
The new libsensors needs these individual alarm files. I did not create alarm files for in5 and in6 as these alarms are documented as not working. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (asb100) De-macro the sysfs callbacksJean Delvare
Use standard dynamic sysfs callbacks instead of macro-generated wrappers. This makes the code more readable, and the binary smaller (by about 12%). Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (asb100) Various cleanupsJean Delvare
* Drop history, it's incomplete and doesn't belong there * Drop unused version number * Drop trailing spaces * Coding style fixes * Fold long lines * Rename new_client to client * Drop redundant initializations to 0 Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: VRM is not written to registersJean Delvare
What was true of reading the VRM value is also true of writing it: not being a register value, it doesn't need hardware access, so we don't need a reference to the i2c client. This allows for a minor code cleanup. As gcc appears to be smart enough to simplify the generated code by itself, this cleanup only affects the source code, the generated binaries are unchanged. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (dme1737) fix Super-IO device ID overrideJuerg Haefliger
The dme1737 has a second place where the Super-IO device ID is checked. This has been missed by Jean's initial patch that adds support for user-controlled Super-IO device ID override. This patch fixes this issue. Signed-off-by: Juerg Haefliger <juergh at gmail.com> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (dme1737) fix divide-by-0Juerg Haefliger
This patch fixes a possible divide-by-0 and a minor bug in the FAN_FROM_REG macro (in TPC mode). Signed-off-by: Juerg Haefliger <juergh at gmail.com> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (abituguru3) Add AUX4 fan input for Abit IP35 ProSergey Vlasov
Abit IP35 Pro has 6 fan connectors (CPU, SYS and AUX1-4), but the entry for AUX4 was missing from the table. Signed-off-by: Sergey Vlasov <vsu@altlinux.ru> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

2008-02-07hwmon: (adm9240) Add individual alarm filesJean Delvare
The new libsensors needs these individual alarm files. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Grant Coady <gcoady.lk@gmail.com> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (lm77) Add individual alarm filesJean Delvare
The new libsensors needs this. As the old library never had support for the lm77 driver, I even dropped the legacy "alarms" file. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: Discard useless I2C driver IDsJean Delvare
Many I2C hwmon drivers define a driver ID but no other code references these, meaning that they are useless. Discard them, along with a few IDs which are defined but never used at all. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (lm85) Make the pwmN_enable files writableJean Delvare
Make the pwmN_enable files writable. This makes it possible to use standard fan speed control tools (pwmconfig, fancontrol) with the lm85 driver. I left the non-standard pwmN_auto_channels files in place, as they give additional control for the automatic mode, and some users might be used to them by now. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (lm85) Return standard values in pwmN_enableJean Delvare
The values returned by the lm85 driver in pwmN_enable sysfs files do not match the standard. Fix that. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (adm1031) Add individual alarm and fault filesJean Delvare
The new libsensors needs these. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (adm1031) Get rid of macro-generated wrappersJean Delvare
Use the standard dynamic sysfs callbacks instead of macro-generated wrappers. It makes the code more simple and the binary smaller (-8% on my system.) Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (adm1031) Various cleanupsJean Delvare
* Rename new_client to client * Drop redundant initializations to 0 * Drop trailing space * Other whitespace cleanups * Split/fold a few long lines * Constify static data * Optimizations in set_fan_div() Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (adm1031) Fix register overwrite in set_fan_div()Jean Delvare
Don't rely on the register cache when setting a new fan clock divider. For one thing, the cache might not have been initialized at all if the driver has just been loaded. For another, the cached values may be old and you never know what can happen in the driver's back. Also invalidate the cache instead of trying to adjust the measured fan speed: the whole point of changing the clock divider is to get a better reading.

2008-02-07hwmon: (it87) Delete pwmN_freq files on driver removalJean Delvare
In commit f8d0c19a93cea3a26a90f2462295e1e01a4cd250 I forgot to delete the pwmN_freq files on driver removal, here's the fix. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Riku Voipio <riku.voipio@movial.fi> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

2008-02-07hwmon: (w83781d) Drop W83627HF supportJean Delvare
The W83627HF hardware monitoring features are supported by the w83627hf driver for several years now. Support by the w83781d has been advertised as deprecated 6 months ago, it's about time to see it go. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (adm1026) Don't create files for missing inputsJean Delvare
On the ADM1026, pins 27 and 28 can be used for two different functions: either temp3, or in8+in9. We should only create the sysfs files for the function that is configured, otherwise it is confusing for the user. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-07hwmon: (adm1026) More cleanups (updated)Jean Delvare
Various cleanups: * Drop an unused define. * Drop unused struct member "type". * Drop one useless instruction. * Drop redundant initializations to 0. * Rename new_client to client. * Drop a useless cast. * Minor code cleanup.

2008-02-07hwmon: (adm1026) Whitespace cleanupsJean Delvare
Whitespace cleanups only: * Trim trailing whitespace. * Use tabs for indentation and alignment. * Add missing space after commas. * Remove extra spaces. No functional change, binary is identical before and after this patch. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
