CVS commit: src/sys/kern

Module Name:    src
Committed By:   christos
Date:           Mon Aug 23 20:53:08 UTC 2010

Modified Files:
        src/sys/kern: exec_subr.c kern_pax.c

Log Message:
Fix issues with stack allocation and pax aslr:
- since the size is unsigned, don't check just that it is > 0, but limit
  it to the MAXSSIZ
- if the stack size is reduced because of aslr, make sure we reduce the
  actual allocation by the same size so that the size does not wrap around.
NB: Must be pulled up to 5.x!
