2018-07-07misc: mic: fix passing the current timeArnd Bergmann
I noticed that the mic driver passes a 'struct timespec64' as part of a message into an attached device, where it is used to set the current system time. This won't actually work if one of the two sides runs a 32-bit kernel and the other runs a 64-bit kernel, since the structure layout is different between the two. I found this while replacing calls to the deprecated do_settimeofday64() interface with the modern ktime_get_real_ts() variant, but it seems appropriate to address both at the same time here. To make sure we have a sane structure, let's define our own structure using the layout of the 64-bit kernel.

2015-10-04misc: mic: Coprocessor State Management (COSM) driverAshutosh Dixit
The COSM driver allows boot, shutdown and reset of Intel MIC devices via sysfs. This functionality was previously present in the Intel MIC host driver but has now been taken out into a separate driver so that it can be shared between multiple generations of Intel MIC products. The sysfs kernel ABI used by the COSM driver is the same as that defined originally for the MIC host driver in Documentation/ABI/testing/sysfs-class-mic.txt. The COSM driver also contains support for dumping the MIC card log_buf and doing a "force reset" for the card via debugfs. The OSPM support present in the MIC host driver has now largely been moved to user space and only a small required OSPM functionality is now present in the driver.
