2018-05-10media: update/fix my e-mail on some placesMauro Carvalho Chehab
There are two places pointing to an unexisting "m.chehab@kernel.org" email. I never had such email, so, I'm unsure how it ends there. Anyway, it is plain wrong. While here, use my canonical e-mail on a bunch of places that are pointing to another e-mail. The idea is that, from now on, all places will be pointing to the same SMTP server.

2018-05-09media: omap3isp: support 64-bit version of omap3isp_stat_dataArnd Bergmann
C libraries with 64-bit time_t use an incompatible format for struct omap3isp_stat_data. This changes the kernel code to support either version, by moving over the normal handling to the 64-bit variant, and adding compatiblity code to handle the old binary format with the existing ioctl command code. Fortunately, the command code includes the size of the structure, so the difference gets handled automatically. In the process of eliminating the references to 'struct timeval' from the kernel, I also change the way the timestamp is generated internally, basically by open-coding the v4l2_get_timestamp() call.

This issue was reported by a user who downloaded a corrupt saa7164 firmware, then went looking for a valid xc5000 firmware to fix the error displayed...but the device in question has no xc5000, thus after much effort, the wild goose chase eventually led to a support call. The xc5000 has nothing to do with saa7164 (as far as I can tell), so replace the string with saa7164 as well as give a meaningful hint on the firmware mismatch.

2018-05-09media: renesas-ceu: Set mbus_fmt on subdev operationsJacopo Mondi
The renesas-ceu driver intializes the desired mbus_format at 'complete' time, inspecting the supported subdevice ones, and tuning some parameters to produce the requested memory format from what the sensor can produce. Although, the initially selected mbus_format was not provided to the subdevice during set_fmt and try_fmt operations, providing instead a '0' mbus format code. As long as the sensor defaults to a compatible mbus_format when an invalid code as '0' is provided, capture operations work correctly. If the subdevice defaults to an unsupported format (eg. some RGB permutations) capture does not work properly due to a mismatch on the expected and received image format on the wire. Fix that by re-using the initially selected mbus_format code during set_fmt and try_fmt subdevice operation calls. Tested by printing out the format selection procedure with ov7670 sensor.

2018-05-09media: videobuf-dma-sg: Fix dma_{sync,unmap}_sg() callsRobin Murphy
This reverts commit fc7f8fd42c2b934ac348995e0c530c917fc277d5. Whilst the rationale for the above commit was in general correct, i.e. that users *consuming* the DMA addresses should rely on sglen rather than num_pages, it has always been the case that the DMA API itself still requires that dma_{sync,unmap}_sg() are called with the original number of entries as passed to dma_map_sg(), not the number of mapped entries it returned. Thus the particular changes made in that patch were erroneous. At worst this might lead to data loss at the tail end of mapped buffers on non-coherent hardware, while at best it's an example of incorrect DMA API usage which has proven to mislead readers.

This should be return an error. In sta2x11_vip_init_one(), Error checking for gpio 'reset_pin' is unnecessary. Because vip_gpio_reserve() is also checking for valid gpio pin.

2018-05-05KVM: x86: remove APIC Timer periodic/oneshot spikesAnthoine Bourgeois
Since the commit "8003c9ae204e: add APIC Timer periodic/oneshot mode VMX preemption timer support", a Windows 10 guest has some erratic timer spikes. Here the results on a 150000 times 1ms timer without any load: Before 8003c9ae204e | After 8003c9ae204e Max 1834us | 86000us Mean 1100us | 1021us Deviation 59us | 149us Here the results on a 150000 times 1ms timer with a cpu-z stress test: Before 8003c9ae204e | After 8003c9ae204e Max 32000us | 140000us Mean 1006us | 1997us Deviation 140us | 11095us The root cause of the problem is starting hrtimer with an expiry time already in the past can take more than 20 milliseconds to trigger the timer function. It can be solved by forward such past timers immediately, rather than submitting them to hrtimer_start(). In case the timer is periodic, update the target expiration and call hrtimer_start with it. v2: Check if the tsc deadline is already expired. Thank you Mika. v3: Execute the past timers immediately rather than submitting them to hrtimer_start(). v4: Rearm the periodic timer with advance_periodic_target_expiration() a simpler version of set_target_expiration(). Thank you Paolo.
