Currently we have some ifdeffery to determine the number of elements in
enum arch_vdso_type as VDSO_TYPES, rather that the usual pattern of
having the enum define this:
| enum foo_type {
| FOO_TYPE_A,
| FOO_TYPE_B,
| #ifdef CONFIG_C
| FOO_TYPE_C,
| #endif
| NR_FOO_TYPES
| }
... however, given we only use this number to size the vdso_lookup[]
array, this is redundant anyway as the compiler can automatically size
the array to fit all defined elements.
So let's remove the VDSO_TYPES to simplify the code.
At the same time, let's use designated initializers for the array
elements so that these are guarnateed to be at the expected indices,
regardless of how we modify the structure. For clariy the redundant
explicit initialization of the enum elements is dropped.
There should be no functional change as a result of this patch.

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.
