2015-12-10drm/i915: Do a better job at disabling primary plane in the noatomic case.Maarten Lankhorst
When disable_noatomic is called plane_mask is not correct yet, and plane_state->visible = true is left as true after disabling the primary plane. Other planes are already disabled as part of crtc sanitization, only the primary is left active. But the plane_mask is not updated here. It gets updated during fb takeover in modeset_gem_init, or set to the new value on resume. This means that to disable the primary plane 1 << drm_plane_index(primary) needs to be used. Afterwards because the crtc is no longer active it's forbidden to keep plane_state->visible set, or a WARN_ON in intel_plane_atomic_calc_changes triggers. There are other code points that rely on accurate plane_state->visible too, so make sure the bool is cleared. The other planes are already disabled in intel_sanitize_crtc, so they don't have to be handled here. Cc: stable@vger.kernel.org #v4.3, v4.2?

2015-12-10rfkill: copy the name into the rfkill structJohannes Berg
Some users of rfkill, like NFC and cfg80211, use a dynamic name when allocating rfkill, in those cases dev_name(). Therefore, the pointer passed to rfkill_alloc() might not be valid forever, I specifically found the case that the rfkill name was quite obviously an invalid pointer (or at least garbage) when the wiphy had been renamed.

2015-12-09ARM: dts: am4372: fix clock source for arm twd and global timersGrygorii Strashko
ARM TWD and Global timer are clocked by PERIPHCLK which is MPU_CLK/2. But now they are clocked by dpll_mpu_m2_ck == MPU_CLK and, as result. Timekeeping core misbehaves. For example, execution of command "sleep 5" will take 10 sec instead of 5. Hence, fix it by adding mpu_periphclk ("fixed-factor-clock") and use it for clocking ARM TWD and Global timer (same way as on OMAP4).

2015-12-09bitops.h: correctly handle rol32 with 0 byte shiftSasha Levin
ROL on a 32 bit integer with a shift of 32 or more is undefined and the result is arch-dependent. Avoid this by handling the trivial case of roling by 0 correctly. The trivial solution of checking if shift is 0 breaks gcc's detection of this code as a ROL instruction, which is unacceptable. This bug was reported and fixed in GCC (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57157): The standard rotate idiom, (x << n) | (x >> (32 - n)) is recognized by gcc (for concreteness, I discuss only the case that x is an uint32_t here). However, this is portable C only for n in the range 0 < n < 32. For n == 0, we get x >> 32 which gives undefined behaviour according to the C standard (6.5.7, Bitwise shift operators). To portably support n == 0, one has to write the rotate as something like (x << n) | (x >> ((-n) & 31)) And this is apparently not recognized by gcc. Note that this is broken on older GCCs and will result in slower ROL.

2015-12-09dm thin metadata: fix bug when taking a metadata snapshotJoe Thornber
When you take a metadata snapshot the btree roots for the mapping and details tree need to have their reference counts incremented so they persist for the lifetime of the metadata snap. The roots being incremented were those currently written in the superblock, which could possibly be out of date if concurrent IO is triggering new mappings, breaking of sharing, etc. Fix this by performing a commit with the metadata lock held while taking a metadata snapshot.

In checking fixes for of_irq_find_parent declaration location, I found that of_msi_map_rid is also wrong. of_msi_map_rid is not implemented for Sparc, so it should not be in the Sparc specific section of the header.

2015-12-09ALSA: hda - Fix noise problems on Thinkpad T440sTakashi Iwai
Lenovo Thinkpad T440s suffers from constant background noises, and it seems to be a generic hardware issue on this model: https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-speaker-noise/td-p/1339883 As the noise comes from the analog loopback path, disabling the path is the easy workaround. Also, the machine gives significant cracking noises at PM suspend. A workaround found by trial-and-error is to disable the shutup callback currently used for ALC269-variant. This patch addresses these noise issues by introducing a new fixup chain. Although the same workaround might be applicable to other Thinkpad models, it's applied only to T440s (17aa:220c) in this patch, so far, just to be safe (you chicken!). As a compromise, a new model option string "tp440" is provided now, though, so that owners of other Thinkpad models can test it more easily.

2015-12-09netfilter: nfnetlink_queue: Unregister pernet subsys in case of init failureNikolay Borisov
Commit 3bfe049807c2403 ("netfilter: nfnetlink_{log,queue}: Register pernet in first place") reorganised the initialisation order of the pernet_subsys to avoid "use-before-initialised" condition. However, in doing so the cleanup logic in nfnetlink_queue got botched in that the pernet_subsys wasn't cleaned in case nfnetlink_subsys_register failed. This patch adds the necessary cleanup routine call.

2015-12-09crypto: skcipher - Copy iv from desc even for 0-len walksJason A. Donenfeld
Some ciphers actually support encrypting zero length plaintexts. For example, many AEAD modes support this. The resulting ciphertext for those winds up being only the authentication tag, which is a result of the key, the iv, the additional data, and the fact that the plaintext had zero length. The blkcipher constructors won't copy the IV to the right place, however, when using a zero length input, resulting in some significant problems when ciphers call their initialization routines, only to find that the ->iv parameter is uninitialized. One such example of this would be using chacha20poly1305 with a zero length input, which then calls chacha20, which calls the key setup routine, which eventually OOPSes due to the uninitialized ->iv member.
