Subject: [C/R v20][PATCH 12/96] c/r: extend arch_setup_additional_pages()
Date: Wed, 17 Mar 2010 12:08:00 -0400 [thread overview]
Message-ID: <1268842164-5590-13-git-send-email-orenl@cs.columbia.edu> (raw)
In-Reply-To: <1268842164-5590-12-git-send-email-orenl@cs.columbia.edu>
From: Alexey Dobriyan <adobriyan@gmail.com>
Add "start" argument, to request to map vDSO to a specific place,
and fail the operation if not.
This is useful for restart(2) to ensure that memory layout is restore
exactly as needed.
Changelog[v19]:
- [serge hallyn] Fix potential use-before-set ret
Changelog[v2]:
- [ntl] powerpc: vdso build fix (ckpt-v17)
