Well, it's a done deal, but here's the proof on parisc too:

Before:

c0266000-c0289000 rwxp 00000000 00:00 0                                  [stack]
c0266000-c0a66000 rwxp 00000000 00:00 0                                  [stack]

After:

bffee000-c0010000 rwxp 00000000 00:00 0                                  [stack]
bffee000-c0010000 rwxp 00000000 00:00 0                                  [stack]
