Description of problem:
For a legacy binary(which doesn't have PT_GNU_STACK program header
and assumes READ implies EXEC behaviour), kernel is mapping data
segment as not executable. Because of this issue java doesn't run on
a processor which supports 'execute disable' feature
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot the x86 kernel on a processor which supports exec disable
2.Run java. It hangs with recursive seg faults.

Proposal for a fix
2.6 kernels have solved this issue by using READ_IMPLIES_EXEC personality.
This problem was resolved in the RHEL3 U4 kernel on 1-Dec-2004
(in kernel version 2.4.21-27.EL).
