John David Anglin 6bb16fa581 parisc: Fix double-word compare and exchange in LWS code on 32-bit kernels ... commit 374b3bf8e8 upstream. As discussed on the debian-hppa list, double-wordcompare and exchange operations fail on 32-bit kernels. Looking at the code, I realized that the ",ma" completer does the wrong thing in the "ldw,ma 4(%r26), %r29" instruction. This increments %r26 and causes the following store to write to the wrong location. Note by Helge Deller: The patch applies cleanly to stable kernel series if this upstream commit is merged in advance: f4125cfdb3 ("parisc: Avoid trashing sr2 and sr3 in LWS code").
