Wire up __vdso_getcpu() for x86-32. The 64bit version is reused with trivial modifications. Contrary to vclock_gettime.c there is no requirement to fake any defines in the case of 32bit VDSO on a 64bit kernel because the GDT entry from which the CPU and node information is read is always the native one. Adopt vdso_getcpu.c by: - removing the unneeded time* header files which lead to compile errors for 32bit. - adding segment.h which provides vdso_read_cpunode() and the defines required by it.

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.
