[PATCH] Replace get_seconds with ktime_get_seconds

[PATCH] dummy_hcd: replace timeval with timespec64

by WEN Pingbo

The millisecond of the last second will be normal if tv_sec is overflowed. But for y2038 consistency and demonstration purpose, and avoiding further risks, we still need to fix it here, to avoid similair problems.

[PATCH] bnx2x: use ktime_get_seconds() for timestamp

by Arnd Bergmann

commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the bnx2x_update_mfw_dump() function that reads the current time and stores it in a 32-bit field that gets passed into a buffer in a fixed format. This is potentially broken when the epoch overflows in 2038, and otherwise overflows in 2106. As we're trying to avoid uses of struct timeval for this reason, I noticed the addition of this function, and tried to rewrite it in a way that is more explicit about the overflow and that will keep working once we deprecate struct timeval. I assume that it is not possible to change the ABI any more, otherwise we should try to use a 64-bit field for the seconds right away.

[PATCH v2 0/5] Introduce 64bit accessors and structures required to address y2038 issues in the posix_clock subsystem

by Baolin Wang

This patch series change the 32-bit time types (timespec/itimerspec) to the 64-bit types (timespec64/itimerspec64), and add new 64bit accessor functions, which are required in order to avoid y2038 issues in the posix_clock subsystem. In order to avoid spamming people too much, I'm only sending the first few patches of the patch series, and left the other patches for later. And if you are interested in the whole patch series, see: https://git.linaro.org/people/baolin.wang/upstream_0627.git Thoughts and feedback would be appreciated. Changes since v1: - Modify the changelog. - Delete one patch without y2038 safe.
