[ Upstream commit 820f188659 ]
aacraid passes the current time to the firmware in one of two ways,
either as year/month/day/... or as 32-bit unsigned seconds.
The first one is broken on 32-bit architectures as it cannot go past
year 2038. Using timespec64 here makes it behave properly on both 32-bit
and 64-bit architectures, and avoids relying on signed integer overflow
to pass times into the second interface.
The interface used in aac_send_hosttime() however is still problematic
in year 2106 when 32-bit seconds overflow. Hopefully we don't have to
worry about aacraid by that time.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
