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().

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.

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.

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

A profile of a network benchmark showed iommu_num_pages rather high up:

Looking at the profile, an integer divide is taking almost all of the time:

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.
