2016-12-14ARM: dts: Remove fimd node from exynos5422-odroidxu3-commonMarek Szyprowski
FIMD device is not used at all on Exynos5422-based Odroid XU3-lite and XU4. XU3 board theorethically can support FIMD with DisplayPort connector, but due to hw limitation/design it doesn't work in most cases. It is also not even enabled in XU3 dts file. FIMD node was enabled mainly due to limitation of early Exynos DRM driver, which didn't initialize properly when no FIMD device was available. This node can be now safely removed from XU3-common dtsi and added layer to Odroid XU3 dts, when Display Port driver gets enabled.

2016-12-14ARM: dts: Add async-bridge clock to MFC power domain for Exynos5420Javier Martinez Canillas
The MFC IP is also inter-connected by an Async-Bridge so the CLK_ACLK333 has to be ungated during a power domain switch. Trying to do it when the clock is gated will fail and lead to an imprecise external abort error when the driver tries to access the MFC registers with the PD disabled. For example, if the s5p-mfc module is removed and the MFC PD turned off: [ 186.835606] Power domain power-domain@10044060 disable failed [ 186.835671] s5p-mfc 11000000.codec: Removing 11000000.codec [ 186.837670] Power domain power-domain@10044060 disable failed And when the module is inserted again: [ 2395.176956] s5p_mfc_wait_for_done_dev:34: Interrupt (dev->int_type:0, command:12) timed out [ 2395.177031] s5p_mfc_init_hw:272: Failed to load firmware [ 2395.177384] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 2395.177441] pgd = ec3b4000 [ 2395.177467] [00000000] *pgd=00000000 [ 2395.177507] Internal error: : 1406 [#1] PREEMPT SMP ARM [ 2395.177550] Modules linked in: s5p_mfc mwifiex_sdio mwifiex uvcvideo s5p_jpeg v4l2_mem2mem videobuf2_vmalloc videobuf2_dma_contig videobuf2_memops videobuf2_v4l2 videobuf2_core v4l2_common videodev media [last unloaded: s5p_mfc] [ 2395.177774] CPU: 1 PID: 2382 Comm: v4l_id Tainted: G W 4.6.0-rc6-next-20160502-00010-g7730dc64d2c1-dirty #179 [ 2395.177857] Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [ 2395.177906] task: ed275500 ti: e6c8c000 task.ti: e6c8c000 [ 2395.177996] PC is at s5p_mfc_reset+0x1c4/0x284 [s5p_mfc] [ 2395.178057] LR is at s5p_mfc_reset+0x1a4/0x284 [s5p_mfc] This patch fixes this issue by adding the CLK_ACLK333 as an Async-Bridge clock for the MFC power domain, so the PD configuration works properly.

2016-12-14s5p-mfc: don't close instance after free OUTPUT buffersayaka
User-space applications can use the VIDIOC_REQBUFS ioctl to determine if a memory mapped, user pointer or DMABUF based I/O is supported by the driver. So a set of VIDIOC_REQBUFS ioctl calls will be made with count 0 and then the real VIDIOC_REQBUFS call with count == n. But for count 0, the driver not only frees the buffer but also closes the MFC instance and s5p_mfc_ctx state is set to MFCINST_FREE. The VIDIOC_REQBUFS handler for the output device checks if the s5p_mfc_ctx state is set to MFCINST_INIT (which happens on an VIDIOC_S_FMT) and fails otherwise. So after a VIDIOC_REQBUFS(n), future VIDIOC_REQBUFS(n) calls will fails unless a VIDIOC_S_FMT ioctl calls happens before the reqbufs. But applications may first set the format and then attempt to determine the I/O methods supported by the driver (for example Gstramer does it) so the state won't be set to MFCINST_INIT again and VIDIOC_REQBUFS will fail. To avoid this issue, only free the buffers on VIDIOC_REQBUFS(0) but don't close the MFC instance to allow future VIDIOC_REQBUFS(n) calls to succeed.

2016-12-14s5p-mfc: Fix race between s5p_mfc_probe() and s5p_mfc_open()Javier Martinez Canillas
The s5p_mfc_probe() function registers the video devices before all the resources needed by s5p_mfc_open() are correctly initalized. So if s5p_mfc_open() function is called before s5p_mfc_probe() finishes (since the video dev is already registered), a NULL pointer dereference will happen due s5p_mfc_open() accessing uninitialized vars such as the struct s5p_mfc_dev .watchdog_timer and .mfc_ops fields. An example is following BUG caused by add_timer() getting a NULL pointer: [ 45.765374] kernel BUG at kernel/time/timer.c:790! [ 45.765381] Internal error: Oops - BUG: 0 [#1] PREEMPT SMP ARM ...

2016-12-14ARM: 8415/1: early fixmap support for earlyconStefan Agner
Add early fixmap support, initially to support permanent, fixed mapping support for early console. A temporary, early pte is created which is migrated to a permanent mapping in paging_init. This is also needed since the attributes may change as the memory types are initialized. The 3MiB range of fixmap spans two pte tables, but currently only one pte is created for early fixmap support. Re-add FIX_KMAP_BEGIN to the index calculation in highmem.c since the index for kmap does not start at zero anymore. This reverts 4221e2e6b316 ("ARM: 8031/1: fixmap: remove FIX_KMAP_BEGIN and FIX_KMAP_END") to some extent.

2016-12-14bitops.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.

2016-12-14UBSAN: run-time undefined behavior sanity checkerAndrey Ryabinin
UBSAN uses compile-time instrumentation to catch undefined behavior (UB). Compiler inserts code that perform certain kinds of checks before operations that could cause UB. If check fails (i.e. UB detected) __ubsan_handle_* function called to print error message. So the most of the work is done by compiler. This patch just implements ubsan handlers printing errors. GCC has this capability since 4.9.x [1] (see -fsanitize=undefined option and its suboptions). However GCC 5.x has more checkers implemented [2].

2016-12-14drm/exynos: gsc: normalize invalid buf idx from userspaceHyungwon Hwang
At least in the one frame processing mode which is the only mode supported by the current gsc driver, the buf idx is not meaningful for the driver. Because only one address in the buffer is valid at a time, so it is OK to convert the invalid buf idx from userspace to a valid idx, process the frame, and return the result with original buf idx.
