Subject: [PATCH v2 0/2] x86: Remove compat vdso support
Date: Wed, 12 Mar 2014 11:29:43 -0700 [thread overview]
Message-ID: <cover.1394648864.git.luto@amacapital.net> (raw)
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 v1:
- CONFIG_ENABLE_VDSO32_BY_DEFAULT now defaults to n
- Improved the config text and description
- Improved the kernel parameter docs
