Description Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2006-08-03 00:49:11 UTC 
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
 
 __futex_atomic_op needs to do an atomic operation in the user address space,
 not the kernel address space.  Add the missing sacf 256/sacf 0 to switch to
 the secondary mode before doing the compare-and-swap.  In addition add
 another fixup for catch specification exceptions if the compare-and-swap
 address is not aligned.

This one is fixed in 2.6.17 and only affects vanilla-sources, closing.
