[PATCH v3 0/2] x86: Remove compat vdso support

[Andy Lutomirski]

This is in the spirit of throwing patches at the list to see what sticks :)

This is intended as an alternative to my compat vdso relocation patches
(http://thread.gmane.org/gmane.linux.kernel/1665080)

v1 of this patch was thoroughly nakked out of existence.  v2 is similar,
but might survive the nakking.  The critical difference is that this
version defaults to the compatible vdso-less mode instead of the modern
incompatible mode.

Changes from v2: Update a comment that I missed.

Changes from v1:
 - CONFIG_ENABLE_VDSO32_BY_DEFAULT now defaults to n
 - Improved the config text and description
 - Improved the kernel parameter docs
