Subject: [PATCH linux-cr] send uses_interp=1 to arch_setup_additional_pages
Date: Wed, 24 Feb 2010 15:33:22 -0600 [thread overview]
Message-ID: <20100224213322.GA3502@us.ibm.com> (raw)
Because the s390 version won't set up vdso if it is 0. It
is safe to assume that if we are calling special_mapping_restore()
then there is a vdso in the checkpoint image, and if that is
the case then the checkpointed program was dynamically linked.
Other architectures ignore uses_interp so this shouldn't
matter to them.
