Some of the changes aren't mine, some are cleanups, some are "obvious", some are not obvious and may well be wrong, or inefficient. I posted the change to not clobber r19 on fork/clone syscalls, but there has been no response to it. I will try split up the change this weekend. > For example, are the futex fixes anywhere for Kyle to pickup? The futex fixes are Helge's and were posted to the list on Wed, 03 Feb 2010 23:03:49 +0100 along with Helge's minifail3.c. The change to syscall.S in the above post included two hunks from me. I removed Helge's portion so that I could enable LWS locking on UP builds because of the concern that a page fault on COW memory could cause user code to be scheduled in the locking code. I think there is merit in using __atomic_user_hash, etc, but it will take a bit of work to make it available in UP kernels. I think Helge's change to fork.c is probably not necessary. Dave -- J.
