MFC uses two clocks - MFC gate clock and special clock which is named as "sclk_mfc" in exynos4 and "aclk_333" in exynos5 SoC. The driver was doing just a clk_prepare on this special clock without a clk_enable call. As this sclk is the parent of gate clock, it gets prepared and enabled along with the gate clock. So there is no need for the driver to use this sclk. This patch removes the sclk usage from driver. Signed-off-by:

The v4l2_m2m_poll() does not need to wait if there is already a buffer in done_list of source and destination queues, but current v4l2_m2m_poll() always waits. So done_list of each queue is checked before calling poll_wait(). Signed-off-by:

MFC v6 needs minimum number of output buffers to be queued for encoder depending on the stream type and profile. The patch modifies the driver so that encoding cannot be started with lesser number of OUTPUT buffers than required. This also fixes the crash happeninig during multi instance encoder-decoder simultaneous run due to memory allocation happening from interrupt context. Signed-off-by:

from commit 3778d050 [media: davinci: kconfig: fix incorrect selects] VIDEO_VPFE_CAPTURE was removed but there was a negative dependancy for building the DM365 VPFE MC based capture driver (VIDEO_DM365_VPFE), This patch fixes this dependency by replacing the VIDEO_VPFE_CAPTURE with VIDEO_DM365_ISIF, so as when older DM365 ISIF v4l driver is selected the newer media controller driver for DM365 isnt visible.

Along the time, several debug messages were added at cx88-cards. While those are still useful to track some troubles with tuners, they're too verbose: [ 5768.281801] cx88[0]: Calling XC2028/3028 callback [ 5768.287388] cx88[0]: Calling XC2028/3028 callback [ 5768.292575] cx88[0]: Calling XC2028/3028 callback [ 5768.299408] cx88[0]: Calling XC2028/3028 callback [ 5768.306244] cx88[0]: Calling XC2028/3028 callback ... and, most of the time, useless. So, disable them, except if core_debug modprobe parameter is used. Signed-off-by: -

variable_is_present() accesses '__efivars' directly, but when called via gsmi_init() Michel reports observing the following crash, BUG: unable to handle kernel NULL pointer dereference at (null) IP: variable_is_present+0x55/0x170 Call Trace: register_efivars+0x106/0x370 gsmi_init+0x2ad/0x3da do_one_initcall+0x3f/0x170 The reason for the crash is that '__efivars' hasn't been initialised nor has it been registered with register_efivars() by the time the google EFI SMI driver runs. The gsmi code uses its own struct efivars, and therefore, a different variable list. Fix the above crash by passing the registered struct efivars to variable_is_present(), so that we traverse the correct list. Reported-by:Michel Lespinasse <walken@google.com> Tested-by:

In commit b0de59b5 ("TTY: do not update atime/mtime on read/write") we removed timestamps from tty inodes to fix a security issue and waited if something breaks. Well, 'w', the utility to find out logged users and their inactivity time broke. It shows that users are inactive since the time they logged in. To revert to the old behaviour while still preventing attackers to guess the password length, we update the timestamps in one-minute intervals by this patch. Signed-off-by:

User applications running on SMP kernels have long suffered from instability and random segmentation faults. This patch improves the situation although there is more work to be done. One of the problems is the various routines in pgtable.h that update page table entries use different locking mechanisms, or no lock at all (set_pte_at). This change modifies the routines to all use the same lock pa_dbit_lock. This lock is used for dirty bit updates in the interruption code. The patch also purges the TLB entries associated with the PTE to ensure that inconsistent values are not used after the page table entry is updated. The UP and SMP code are now identical. The change also includes a minor update to the purge_tlb_entries function in cache.c to improve its efficiency. Signed-off-by:
