Date: Tue, 26 Feb 2013 10:09:06 -0500 From: Mark Salter <msalter@...hat.com> To: Alexander Viro <viro@...iv.linux.org.uk> Cc: linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org, Mark Salter <msalter@...hat.com> Subject: [PATCH 1/2] Fix AT_EXECFN auxv for no-MMU fdpic In the no-MMU case, the FDPIC loader was passing an offset as the value for the AT_EXECFN auxv. This patch translates that offset into an actual user address.
