Subject: [patch] remove MNT_NOEXEC check for PROT_EXEC mmaps

Hi Andrew.

I am not sure at all whether this patch is appreciated
or not. The on-list query yielded no results, but I have
to try. :)

This patch removes the MNT_NOEXEC check for the PROT_EXEC
mappings. That allows to mount tmpfs with "noexec" option
without breaking the existing apps, which is what debian
wants to do for sequrity reasons:
