Use the magic LIST_POISON* values to detect an incorrect use of list_del on a deleted entry. This DEBUG_LIST specific warning is easier to understand than the generic Oops message caused by LIST_POISON dereference. Signed-off-by:

kmsg_dump takes care to sample the global variables inside a spinlock, but then goes on to use the same variables outside the spinlock region too. Use the correct variable. This will make the race window smaller. Found by gcc 4.6's new warnings. Signed-off-by:

The previous change added WARN_ON() in misc_deregister(). So it is not necessary to WARN_ON() misc_deregister() failure by callers. Signed-off-by:

misc_deregister() returns an error only when it attempts to unregister the device that is not registered. This is the driver's bug. Most of the drivers don't check the return value of misc_deregister(). (It is not bad thing because most of kernel *_unregister() API always succeed and do not return value) So it is better to indicate the error by WARN_ON() in misc_deregister(). Signed-off-by:

Using: gcc (GCC) 4.5.0 20100610 (prerelease) The following warning appears: init/main.c: In function `do_one_initcall': init/main.c:730:10: warning: `calltime.tv64' may be used uninitialized in this function This warning is actually correct, as the global initcall_debug could arguably be changed by the initcall. Correct this warning by extracting a new function, do_one_initcall_debug, that performs the initcall for the debug case. Signed-off-by:

Cleanup, no functional changes. - __set_personality() always changes ->exec_domain/personality, the special case when ->exec_domain remains the same buys nothing but complicates the code. Unify both cases to simplify the code. - The -EINVAL check in sys_personality() was never right. If we assume that set_personality() can fail we should check the value it returns instead of verifying that task->personality was actually changed. Remove it. Before the previous patch it was possible to hit this case due to overflow problems, but this -EINVAL just indicated the kernel bug. OTOH, probably it makes sense to change lookup_exec_domain() to return ERR_PTR() instead of default_exec_domain if the search in exec_domains list fails, and report this error to the user-space. But this means another user-space change, and we have in-kernel users which need fixes. For example, PER_OSF4 falls into PER_MASK for unkown reason and nobody cares to register this domain.

This driver adds support for the BMP085 digital pressure sensor from Bosch Sensortec. It exposes a sysfs api to userspace where pressure and temperature measurement results can be read from the pressure0_input and temp0_input file. The chip is able to calculate the average of up to eight samples to increase the accuracy. This feature can be controlled by writing to the oversampling file. The BMP085 digital pressure sensor can measure ambient air pressure and temperature. Both values can be obtained from sysfs files. The pressure is measured by reading from pressure0_input. Valid values range from 30000 to 110000 pascal with a resolution of 1 pascal (=0.01 millibar). temp0_input holds the current temperature in degree celsius, multiplied by 10. This results in a resolution of a tenth degree celsius. Values range from -400 to 850. To increase the accuracy, this chip can calculate the average of 1, 2, 4 or 8 samples. This behavior is controlled through the oversampling sysfs file. Two to the power of the value written to that file specifies how many samples will be used. Valid values: 0..3.

Add support for ROHM BH1780GLI Ambient light sensor. BH1780 supports I2C interface. Driver supports read/update of power state and read of lux value (through SYSFS). Writing value 3 to power_state enables the sensor and current lux value could be read. Currently this driver follows the same sysfs convention as supported by drivers/misc/isl29003.c. Signed-off-by:

A profile of a network benchmark showed iommu_num_pages rather high up: 0.52% iommu_num_pages Looking at the profile, an integer divide is taking almost all of the time: % : c000000000376ea4 <.iommu_num_pages>: 1.93 : c000000000376ea4: fb e1 ff f8 std r31,-8(r1) 0.00 : c000000000376ea8: f8 21 ff c1 stdu r1,-64(r1) 0.00 : c000000000376eac: 7c 3f 0b 78 mr r31,r1 3.86 : c000000000376eb0: 38 84 ff ff addi r4,r4,-1 0.00 : c000000000376eb4: 38 05 ff ff addi r0,r5,-1 0.00 : c000000000376eb8: 7c 84 2a 14 add r4,r4,r5 46.95 : c000000000376ebc: 7c 00 18 38 and r0,r0,r3 45.66 : c000000000376ec0: 7c 84 02 14 add r4,r4,r0 0.00 : c000000000376ec4: 7c 64 2b 92 divdu r3,r4,r5 0.00 : c000000000376ec8: 38 3f 00 40 addi r1,r31,64 0.00 : c000000000376ecc: eb e1 ff f8 ld r31,-8(r1) 1.61 : c000000000376ed0: 4e 80 00 20 blr Since every caller of iommu_num_pages passes in a constant power of two we can inline this such that the divide is replaced by a shift. The entire function is only a few instructions once optimised, so it is a good candidate for inlining overall.

Luckily, it appears as though the standard offsetof() macro is what is being implemented by NAME_OFFSET(), thus we can fix the warning and use a more standard code construct at the same time.
