Subject: [PATCH] i386 kernel instant reboot with older binutils fix
Date: Wed, 3 Jan 2007 09:46:45 +0530 [thread overview]
Message-ID: <20070103041645.GA17546@in.ibm.com> (raw)
o i386 kernel reboots instantly if compiled with binutils older than
2.6.15.
o Older binutils required explicit flags to mark a section allocatable
and executable(AX). Newer binutils automatically mark a section AX if
the name starts with .text.
o While defining a new section using assembler "section" directive,
explicitly mention section flags.
