As a preparation to stop using 'struct timespec' in the kernel, change the powerpc vdso implementation: - split up the vdso data definition to have equivalent members for seconds and nanoseconds instead of an xtime structure - use timespec64 as an intermediate for the xtime update - change the asm-offsets definition to be based the appropriate fixed-length types This is only a temporary fix for changing the types, in order to actually support a 64-bit safe vdso32 version of clock_gettime(), the entire powerpc vdso should be replaced with the generic lib/vdso/ implementation. If that happens first, this patch becomes obsolete. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
