2016-04-05mac80211: add doc for RX_FLAG_DUP_VALIDATED flagLuis de Bethencourt1-0/+2

2016-04-05mac80211: ensure no limits on station rhashtableBen Greear1-0/+1
By default, the rhashtable logic will fail to insert objects if the key-chains are too long and un-balanced. In the degenerate case where mac80211 is creating many virtual interfaces connected to the same peer(s), this case can happen. St insecure_elasticity to true to allow chains to grow as long as needed.

2016-04-05mac80211: properly deal with station hashtable insert errorsJohannes Berg1-5/+8
The original hand-implemented hash-table in mac80211 couldn't result in insertion errors, and while converting to rhashtable I evidently forgot to check the errors. This surfaced now only because Ben is adding many identical keys and that resulted in hidden insertion errors.

2016-04-05mac80211: recalc min_def chanctx even when chandef is identicalArik Nemtsov1-1/+3
The min_def chanctx is affected not only by the current chandef, but sometimes also by other stations on the vif. There's a valid scenario where a TDLS peer can widen its BW, thereby causing the min_def to increase.

2016-04-05mac80211: TDLS: change BW calculation for WIDER_BW peersArik Nemtsov3-11/+61
The previous approach simply ignored chandef restrictions when calculating the appropriate peer BW for a WIDER_BW peer. This could result in a regulatory violation if both peers indicated 80MHz support, but the regdomain forbade it. Change the approach to setting a WIDER_BW peer's BW. Don't exempt it from the chandef width at first. If during TDLS negotiation the chandef width is upgraded, update the peer's BW to match.

2016-04-05drm: bridge: analogix/dp: Fix the possible dead lock in bridge disable timeYakir Yang3-36/+55
It may caused a dead lock if we flush the hpd work in bridge disable time. The normal flow would like: IN --> DRM IOCTL 1. Acquire crtc_ww_class_mutex (DRM IOCTL) IN --> analogix_dp_bridge 2. Acquire hpd work lock (Flush hpd work) 3. HPD work already in idle, no need to run the work function. OUT <-- analogix_dp_bridge OUT <-- DRM IOCTL The dead lock flow would like: IN --> DRM IOCTL 1. Acquire crtc_ww_class_mutex (DRM IOCTL) IN --> analogix_dp_bridge 2. Acquire hpd work lock (Flush hpd work) IN --> analogix_dp_hotplug IN --> drm_helper_hpd_irq_event 3. Acquire mode_config lock (This lock already have been acquired in previous step 1) ** Dead Lock Now ** It's wrong to flush the hpd work in bridge->disable time, I guess the original code just want to ensure the delay work must be finish before encoder disabled. The flush work in bridge disable time is try to ensure the HPD event won't be missed before display card disabled, actually we can take a fast respond way(interrupt thread) to update DRM HPD event to fix the delay update and possible dead lock.

Split the dp core driver from exynos directory to bridge directory, and rename the core driver to analogix_dp_*, rename the platform code to exynos_dp. Beside the new analogix_dp driver would export six hooks. "analogix_dp_bind()" and "analogix_dp_unbind()" "analogix_dp_suspned()" and "analogix_dp_resume()" "analogix_dp_detect()" and "analogix_dp_get_modes()" The bind/unbind symbols is used for analogix platform driver to connect with analogix_dp core driver. And the detect/get_modes is used for analogix platform driver to init the connector. They reason why connector need register in helper driver is rockchip drm haven't implement the atomic API, but Exynos drm have implement it, so there would need two different connector helper functions, that's why we leave the connector register in helper driver.

When user sets performance policy using cpufreq interface, it is possible that because of policy->max limits, the actual performance is still limited. But the current implementation will silently switch the policy to powersave and start using powersave limits. If user modifies any limits using intel_pstate sysfs, this is actually changing powersave limits. The current implementation tracks limits under powersave and performance policy using two different variables. When policy->max is less than policy->cpuinfo.max_freq, only powersave limit variable is used. This fix causes the performance limits variable to be used always when the policy is performance.

2016-04-04bridge: Fix incorrect variable assignment on error path in br_sysfs_addbrBastien Philbert1-0/+1
This fixes the incorrect variable assignment on error path in br_sysfs_addbr for when the call to kobject_create_and_add fails to assign the value of -EINVAL to the returned variable of err rather then incorrectly return zero making callers think this function has succeededed due to the previous assignment being assigned zero when assigning it the successful return value of the call to sysfs_create_group which is zero.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into usb-linus Jonathan writes: First round of IIO fixes for the 4.6 cycle. Again I've ended up with two early fix sets, depending on whether they are dependent on elements of the merge window or simply came in after I had patches with that dependency already, vs older fixes that were just too late for the last cycle. This first set is for the older ones. - max1353 * Add a missing adc to max1363_id - the driver has supported the max11644-11647 for a while, but as they weren't in the id table there was no way of actually initializing it. * Fix a wrong reference voltage for the above models. Given you couldn't initialize the driver for these parts without patching, no one noticed that the reference voltage used in computing the scaling was wrong. - apds9960 * The fifo last enelement was read twice (and hence pushed out twice) due to a small logic bug.
2016-04-04gma500: remove annoying deprecation warningLinus Torvalds1-1/+1
In commit e45708976aea ("drm/dp-helper: Move the legacy helpers to gma500") the legacy i2c helpers were moved to the only remaining user of them, the gma500 driver. Together with that move, i2c_dp_aux_add_bus() was marked deprecated and started warning about its remaining use. It's now been a year and a half of annoying warning, and apparently nobody cares enough about gma500 to try to move it along to the more modern models. Get rid of the warning - if even the gma500 people don't care enough, then they should certainly not spam other innocent developers with a warning that might hide other, much more real issues.

2016-04-04Merge branch 'PAGE_CACHE_SIZE-removal'Linus Torvalds398-2869/+2840
Merge PAGE_CACHE_SIZE removal patches from Kirill Shutemov: "PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE. This promise never materialized. And unlikely will. Let's stop pretending that pages in page cache are special. They are not. The first patch with most changes has been done with coccinelle. The second is manual fixups on top. The third patch removes macros definition" [ I was planning to apply this just before rc2, but then I spaced out, so here it is right _after_ rc2 instead. As Kirill suggested as a possibility, I could have decided to only merge the first two patches, and leave the old interfaces for compatibility, but I'd rather get it all done and any out-of-tree modules and patches can trivially do the converstion while still also working with older kernels, so there is little reason to try to maintain the redundant legacy model. - Linus ] * PAGE_CACHE_SIZE-removal: mm: drop PAGE_CACHE_* and page_cache_{get,release} definition mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros
