2018-01-22scsi: arcmsr: avoid do_gettimeofdayArnd Bergmann
The arcmsr uses its own implementation of time_to_tm(), along with do_gettimeofday() to read the current time. While the algorithm used here is fine in principle, it suffers from two problems: - it assigns the seconds portion of the timeval to a 32-bit unsigned integer that overflows in 2106 even on 64-bit architectures. - do_gettimeofday() returns a time_t that overflows in 2038 on all 32-bit systems. This changes the time retrieval function to ktime_get_real_seconds(), which returns a proper 64-bit value, and replaces the open-coded time_to_tm() algorithm with a call to the safe time64_to_tm(). I checked way all numbers are indexed and found that months are given in range 0..11 while the days are in range 1..31, same as 'struct tm', but the year value that the firmware expects starts in 2000 while 'struct tm' is based on year 1900, so it needs a small adjustment.

2018-01-22scsi: megaraid_sas: NVMe passthrough command supportShivasharan S
NVMe passthrough via MFI interface. Current MegaRAID product supports different types of encapsulation via the MFI framework. NVMe native command should be framed by application and it should be embedded in MFI as payload. The driver will provide interface to send the MFI frame along with the payload (in this case, payload is NVMe native command) to the firmware. Driver already has an existing, similar interface for SATA and SMP passthrough. 1. Driver will pass MFI command to the firmware if the latter supports NVMe encapsulated processing (not all SAS3.5 firmware supports this feature). 2. Driver exposes sysfs entry support_nvme_encapsulation. This is required for backward compatibility for applications using earlier driver versions that did not process IOCTL frames and could result in host hang.

To ease analyzing boot behavior from logs, let's log when we are about to register the pass-through serio port. Also, let's drop "Synaptics" prefix from the port name, as RMI4 is good enough indicator already, and having the prefix means that the name does not fit into serio->name field.

2018-01-22Input: synaptics-rmi4 - unmask F03 interrupts when port is openedDmitry Torokhov
Currently we register the pass-through serio port when we probe the F03 RMI function, and then, in sensor configure phase, we unmask interrupts. Unfortunately this is too late, as other drivers are free probe devices attached to the serio port as soon as it is probed. Because interrupts are masked, the IO times out, which may result in not being able to detect trackpoints on the pass-through port. To fix the issue we implement open() and close() methods for the pass-through serio port and unmask interrupts from there. We also move creation of the pass-through port form probe to configure stage, as RMI driver does not enable transport interrupt until all functions are probed (we should change this, but this is a separate topic). We also try to clear the pending data before unmasking interrupts, because some devices like to spam the system with multiple 0xaa 0x00 announcements, which may interfere with us trying to query ID of the device.

The newer trackpoints also do not implement "Power On Reset" or "Read Extended Button Status", so we should not be using these commands during initialization.

Broadcom tags inserted by Broadcom switches put a 4 byte header after the MAC SA and before the EtherType, which may look like some sort of 0 length LLC/SNAP packet (tcpdump and wireshark do think that way). With ACS enabled in stmmac the packets were truncated to 8 bytes on reception, whereas clearing this bit allowed normal reception to occur. In order to make that possible, we need to pass a net_device argument to the different core_init() functions and we are dependent on the Broadcom tagger padding packets correctly (which it now does). To be as little invasive as possible, this is only done for gmac1000 when the network device is DSA-enabled (netdev_uses_dsa() returns true).
