5150bda43c checkpatch: change externals to globals
Make error message say 'ERROR: do not initialise globals to 0 or NULL'
rather than 'ERROR: do not initialise externals to 0 or NULL'.  Makes more
sense in the context since there is an extern keyword in C and that is a
global declaration within the scope of the current file.

5f7ddae610 checkpatch: fix handling of leading spaces
I've got a false positive when spaces are present at the beginning of a
line.

So I add this check, obviously excluding to check the lines in the middle of
comments.

For instance this code passes the checkpatch test:

+struct davinci_mcbsp_data {
+       unsigned int    fmt;
+    int             clk_div;
+};
+
+static struct davinci_mcbsp_data mcbsp_data;

Where, before the string "int             clk_div", I have 4 spaces (\040
ascii character).

With v2.6.34 scripts/checkpatch.pl script I get:

scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch
total: 0 errors, 0 warnings, 201 lines checked
0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch has no obvious style
problems and is ready for submission.

That is not correct.  Instead with the proposed patch I get:

scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch
WARNING: please, no space for starting a line,
                excluding comments
#63: FILE: sound/soc/davinci/davinci-i2s.c:165:
+    int             clk_div;$

WARNING: please, no space for starting a line,
                excluding comments
#95: FILE: sound/soc/davinci/davinci-i2s.c:406:
+    return 0;$

total: 0 errors, 2 warnings, 201 lines checked

That is correct.

ea98eed9bc flex_array: add helpers to get and put to make pointers easy to use
Getting and putting arrays of pointers with flex arrays is a PITA.  You
have to remember to pass &ptr to the _put and you have to do weird and
wacky casting to get the ptr back from the _get.  Add two functions
flex_array_get_ptr() and flex_array_put_ptr() to handle all of the magic.

b329becfc7 char: add WARN_ON() in misc_deregister()
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().

22c5c03b42 init/main.c: fix warning: 'calltime.tv64' may be used uninitialized
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.

2ee7c922f2 sys_personality: remove the bogus checks in sys_personality()->__set_personality() path
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.

5bf1d290b5 drivers/misc: support for the pressure sensor BMP085 from Bosch Sensortec
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.

7efe15f2a4 drivers/misc: ROHM BH1780GLI ambient light sensor driver
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.

e269b08517 iommu: inline iommu_num_pages
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.

85c9fe8fca vfs: fix warning: 'dirent' is used uninitialized in this function
Using:

	gcc (GCC) 4.5.0 20100610 (prerelease)

The following warnings appear:

	fs/readdir.c: In function `filldir64':
	fs/readdir.c:240:15: warning: `dirent' is used uninitialized in this function
	fs/readdir.c: In function `filldir':
	fs/readdir.c:155:15: warning: `dirent' is used uninitialized in this function
	fs/compat.c: In function `compat_filldir64':
	fs/compat.c:1071:11: warning: `dirent' is used uninitialized in this function
	fs/compat.c: In function `compat_filldir':
	fs/compat.c:984:15: warning: `dirent' is used uninitialized in this function

The warnings are related to the use of the NAME_OFFSET() macro.  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.

PROC_MM doesn't exist in Kconfig.  Looking around it looks like a
left-over from 2.6.0 or even 2.4 times, last mentioned in a fedora patch
for 2.6.10.  I believe it's time to get rid of that last tiny parts here
that are still around.
