A patch to remove VM_EXEC from VM_DATA_DEFAULT_FLAGS for MIPS has been
submitted to me with the primary motivation for this change being
some performance improvment.  In other words, the patch would remove
execute permission from a process brk area.  It's however unclear to
me how much software wreckage would result from such a change, even
if the execute permission for the stack area remains unchanged.

So, what would break?

Thanks,

  Ralf
