2017-03-01bpf: update the comment about the length of analysisGary Lin
Commit 07016151a446 ("bpf, verifier: further improve search pruning") increased the limit of processed instructions from 32k to 64k, but the comment still mentioned the 32k limit. This commit updates the comment to reflect the change.

2017-03-01CIFS: Fix possible use after free in demultiplex threadPavel Shilovsky
The recent changes that added SMB3 encryption support introduced a possible use after free in the demultiplex thread. When we process an encrypted packed we obtain a pointer to SMB session but do not obtain a reference. This can possibly lead to a situation when this session was freed before we copy a decryption key from there. Fix this by obtaining a copy of the key rather than a pointer to the session under a spinlock. Signed-off-by: Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <smfrench@gmail.com>

2017-03-01drm/rockchip: dw-mipi-dsi: improve PLL configurationJohn Keeping
The multiplication ratio for the PLL is required to be even due to the use of a "by 2 pre-scaler". Currently we are likely to end up with an odd multiplier even though there is an equivalent set of parameters with an even multiplier. For example, using the 324MHz bit rate with a reference clock of 24MHz we end up with M = 27, N = 2 whereas the example in the PHY databook gives M = 54, N = 4 for this bit rate and reference clock. By walking down through the available multiplier instead of up we are more likely to hit an even multiplier. With the above example we do now get M = 54, N = 4 as given by the databook. While doing this, change the loop limits to encode the actual limits on the divisor, which are: 40MHz >= (pllref / N) >= 5MHz Signed-off-by: John Keeping <john@metanate.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: http://patchwork.freedesktop.org/patch/msgid/20170224125506.21533-18-john@metanate.com

2017-03-01Input: rmi4 - f30: detect INPUT_PROP_BUTTONPAD from the button countBenjamin Tissoires
INPUT_PROP_BUTTONPAD is currently only set through the platform data. The RMI4 header doc says that this property is there to force the buttonpad property, so we also need to detect it by looking at the exported buttons count.

2017-03-01Merge branch 'vxlan-geneve-rcu-fixes'David S. Miller
Jakub Kicinski says: ==================== VXLAN/geneve RCU fixes VXLAN and GENEVE need to take RCU lock explicitly because TX path only has the _bh() flavour of RCU locked. Making the reconfiguration path wait for both normal and _bh() RCU would be bigger hassle so just acquire the lock, as suggested by Pravin: https://www.mail-archive.com/netdev@vger.kernel.org/msg155583.html ==================== Signed-off-by: David S.
