Sergio Paracuellos 0d8be3067f staging: ks7010: change parameter types in hostif_power_mgmt_request
Parameters for hostif_power_mgmt_request are declared as unsigned
long and then are forced to be change to be u32. Also the caller
declares explicitly unsigned long parameters just to assign them
and pass into the function. Change types for those to be u32 instead
so no conversion is needed at all and code gets more clear.

Sergio Paracuellos 8ce76bff0e staging: ks7010: add new helpers to achieve mib set request and simplify code
New three functions have been created to centralice and simplify
calls related with set MIB requests:

    - hostif_mib_set_request_int
    - hostif_mib_set_request_bool
    - hostif_mib_set_request_ostring

Using these in different calls simplify functions related with
this mainly when types are bool and int because no more conversions
are needed in the caller functions. Those conversion details are
now located in the new helpers improving a lot readability. Calls
in hostif_sme_set_wep function has change also some if's to check
invalid value first avoiding one level indentation.

makes no longer necessary to have ks7010_sdio.h header as well as
removes the forward dependency in ks_wlan.h. Declaration of
ks_sdio_card has been moved to ks7010_sdio.c source file and To make
code cleaner inside this file a new ks7010_to_func function has been

An issue is observed where mallocs are failing due to overcommit failure.
The failure happens when there is high ION page pool since ION page
pool is not considered reclaimable by the overcommit calculation code.
This change considers ion pool pages as indirectly reclaimable and thus

Wenwen Wang dc487321b1 staging: lustre: llite: fix potential missing-check bug when copying lumv
In ll_dir_ioctl(), the object lumv3 is firstly copied from the user space
using Its address, i.e., lumv1 = &lumv3. If the lmm_magic field of lumv3 is
LOV_USER_MAGIC_V3, lumv3 will be modified by the second copy from the user
space. The second copy is necessary, because the two versions (i.e.,
lov_user_md_v1 and lov_user_md_v3) have different data formats and lengths.
However, given that the user data resides in the user space, a malicious
user-space process can race to change the data between the two copies. By
doing so, the attacker can provide a data with an inconsistent version,
e.g., v1 version + v3 data. This can lead to logical errors in the
following execution in ll_dir_setstripe(), which performs different actions
according to the version specified by the field lmm_magic.

This patch rechecks the version field lmm_magic in the second copy.  If the
version is not as expected, i.e., LOV_USER_MAGIC_V3, an error code will be
returned: -EINVAL.

NeilBrown 648ae36362 staging: lustre: ldlm: store name directly in namespace.
Rather than storing the name of a namespace in the
hash table, store it directly in the namespace.
This will allow the hashtable to be changed to use
rhashtable.

Brian Masney 498efcd081 staging: iio: tsl2x7x: correct integration time and lux equation
The integration_time sysfs attribute did not report the correct
time. Changing the integration time would cause the reported lux to
change wildly. Once the integration time was corrected, all of the
equations, and lux tables needed to be corrected to match what the
data sheets expected. This patch corrects all of this, and adds some
more comments about how some of the constants were derived. Here are
the results from testing a TSL2772 hooked up to a Raspberry Pi 2:

# cat in_intensity0_integration_time
0.002730
# watch -n .1 cat in_illuminance0_input
; Lux hovers around 55
# echo 0.65 > in_intensity0_integration_time
# cat in_intensity0_integration_time
0.649740
# watch -n .1 cat in_illuminance0_input
; Lux hovers around 55 with noticeable lag to lux changes in watch
; process.

; Now test the ALS calibration routine.
# cat in_intensity0_calibbias
1000
# cat in_illuminance0_target_input
150
# echo 1 > in_illuminance0_calibrate
# cat in_intensity0_calibbias
2777
# watch -n .1 cat in_illuminance0_input
; Lux now hovers around 150-155

The returned lux values were tested on a TSL2772 in various lighting
conditions and the results are within the lux ranges described at
https://en.wikipedia.org/wiki/Lux.

The driver was primarily tested using a TSL2772, however some quick tests
were also ran against the devices TSL2771, TSL2572, and TMD2772.

Brian Masney 11031d7df0 staging: iio: tsl2x7x: use IIO_CONST_ATTR for calibscale_available
The in_intensity0_calibscale_available sysfs attribute has code that
checks the device type to determine which calibration scales are
available. This check is not necessary since all of the supported
ALS device types use the scales 1 8 16 120. This patch converts the
sysfs attribute to use IIO_CONST_ATTR. The following device datasheets
were checked: tsl2571, tsl2771, tmd2771, tsl2572, tsl2772, tmd2772.
