This patch kills another macro abuse in the via686a hardware monitoring driver. Using a macro just to alias an array is quite useless, isn't it? Signed-off-by:

The via686a hardware monitoring driver has infamous coding style at the moment. I'd like to clean up the mess before I start working on other changes to this driver. Is the following patch acceptable? No code change, only coding style (indentation, alignments, trailing white space, a few parentheses and a typo). Signed-off-by:

This patch kills a common macro abuse in i2c chip drivers: defining ALARMS_FROM_REG returning its argument unchanged. Dropping the macro makes the code somewhat more readable IMHO. Signed-off-by:

This patch adds an info print of detected VRM stolen from Sebastian Witt's atxp1 sriver. ADM9240 already has vrm accessor removed. Write no-op and whitespace fixes removed :) Couple of comments changed, tested on 2.6.11.9. Signed-off-by:

This small patch changes two drivers, adm1025 and adm1026, to report vid as cpu0_vid sysfs name as used by the other drivers. Added duplicated names and six month warning for old names to be removed as requested. Compile tested. Signed-off-by:

Jarkko Lavinen provided patch to fix: "couldn't set the divisor 128 through fan1_div sysfs entry even though the chip supports it and setting divisors 1..64 worked. This was due to POWER_TO_REG() only checking 2's powers 0 till 5 but not 6." This patch applies that fix to w83627hf and w83781d drivers. Signed-off-by:

In my cross-reference checking of sysfs names, the via686a needs special case treatment as it the only driver expands S_IWUSR to 00200 with gcc -E. (00200 is the correct value for S_IWUSR). This is caused by the driver including <linux/delay.h>, it compiles fine without that header but I am unable to test drive the change. Signed-off-by:

Call i2c_transfer() from i2c_master_send() and i2c_master_recv() to avoid the redundant code that was in all three functions. It also removes unnecessary debug statements as suggested by Jean Delvare. This is important for the non-blocking interfaces because they will have to handle a non-blocking interface in this area. Having it in one place greatly simplifies the changes. Signed-off-by:

This simple patch adds support for the SMSC LPC47M15x and LPC47M192 chips to the smsc47m1 hardware monitoring driver. These chips are compatible with the other ones already supported by the driver, so I see no reason not to support them, especially when the Linux 2.4 version of the driver does already. I also modified the info printks to name the chips by their real name. Signed-off-by:

Jean Delvare authored
This is a new hardware monitoring driver, w83627ehf, which supports the Winbond W83627EHF Super-I/O chip. The driver is not complete, but already usable. It only implements fan speed and temperature monitoring, while the chip also supports voltage inputs with VID, PWM output and temperature sensor selection. I have no more time to work on this, but anyone with supported hardware could add the missing functionalities later. This driver is largely derived from the w83627hf driver. Thanks to Leon Moonen and Steve Cliffe for tesing the preliminary versions of my driver and reporting the problems they encountered. Thanks to Grant Coady for noticing and fixing various corner cases in the fan management. This third version of the driver hopefully addresses all the issues the original version had. Signed-off-by:

Hi Alexey, > Files that don't use CONFIG_* stuff shouldn't include config.h > Files that use CONFIG_* stuff should include config.h > > It's that simple. ;-) I agree. This won't change anything though, as all drivers include either device.h or module.h, which in turn include config.h. But you are still correct, so I approve your patch. For completeness, I would propose the following on top of your own patch: i2c bus drivers do not need to define DEBUG themselves, as the Kconfig system takes care of it. Signed-off-by:

On top of my previous patch which removes the use of address ranges in video i2c drivers, this one can save an additional few bytes of memory. Most of these drivers which do not use I2C_CLIENT_INSMOD initialize the unused address lists in a less than optimal way. This patch simply optimizes this, by using a single one-element list instead of 3 different lists with two elements each. This saves an average 63 bytes on these drivers. Signed-off-by:

Some months ago, you killed the address ranges mechanism from all sensors i2c chip drivers (both the module parameters and the in-code address lists). I think it was a very good move, as the ranges can easily be replaced by individual addresses, and this allowed for significant cleanups in the i2c core (let alone the impressive size shrink for all these drivers). Unfortunately you did not do the same for non-sensors i2c chip drivers. These need the address ranges even less, so we could get rid of the ranges here as well for another significant i2c core cleanup. Here comes a patch which does just that. Since the process is exactly the same as what you did for the other drivers set already, I did not split this one in parts. A documentation update is included. The change saves 308 bytes in the i2c core, and an average 1382 bytes for chip drivers which use I2C_CLIENT_INSMOD, 126 bytes for those which do not. This change is required if we want to merge the sensors and non-sensors i2c code (and we want to do this). Signed-off-by:

Due to the use of write-behind, it is possible for md to write a page to the bitmap file that is still completing writeback. This is not allowed. With this patch, we detect those cases and either force a sync write, or back off and try later, as appropriate. Signed-off-by:

1/ Must typecast int to (sector_t) before inverting or we might not invert enough bits. 2/ When "bitmap_offset" was added to mdp_superblock_1, we didn't increase the count of words-used (96 to 100). Signed-off-by:

NeilBrown authored
currently, md updates all superblocks (one on each device) in series. It waits for one write to complete before starting the next. This isn't a big problem as superblock updates don't happen that often. However it is neater to do it in parallel, and if the drives in the array have gone to "sleep" after a period of idleness, then waking them is parallel is faster (and someone else should be worrying about power drain). Futher, we will need parallel superblock updates for a future patch which keeps the intent-logging bitmap near the superblock. Also remove the silly code that retired superblock updates 100 times. This simply never made sense. Signed-off-by:

This provides an alternate to storing the bitmap in a separate file. The bitmap can be stored at a given offset from the superblock. Obviously the creator of the array must make sure this doesn't intersect with data.... After is good for version-0.90 superblocks. Signed-off-by:

Before completing a 'write' the md superblock might need to be updated. This is best done by the md_thread. The current code schedules this up and queues the write request for later handling by the md_thread. However some personalities (Raid5/raid6) will deadlock if the md_thread tries to submit requests to its own array. So this patch changes things so the processes submitting the request waits for the superblock to be written and then submits the request itself. This fixes a recently-created deadlock in raid5/raid6 Signed-off-by:
