* [POWERPC] spufs: Synchronize pte invalidation vs ps closeChristoph Hellwig2007-06-06
| | | | | | | | | | | | | Make sure the mapping_lock also protects access to the various address_space pointers used for tearing down the ptes on a spu context switch. Because unmap_mapping_range can sleep we need to turn mapping_lock from a spinlock into a sleeping mutex.

* [POWERPC] spufs: Fix gang destroy leaksJeremy Kerr2007-06-06
| | | | | | | | | | | | | | | Previously, closing a SPE gang that still has contexts would trigger a WARN_ON, and leak the allocated gang. This change fixes the problem by using the gang's reference counts to destroy the gang instead. The gangs will persist until their last reference (be it context or open file handle) is gone. Also, avoid using statements with side-effects in a WARN_ON().

| | | | | | | | | | | | | | | | | | An xattr_datum which ends up orphaned should be freed by the GC thread.

| * [JFFS2] Fix BUG() caused by failing to discard xattrs on deleted files.David Woodhouse2007-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we cannot mark nodes as obsolete, such as on NAND flash, we end up having to delete inodes with !nlink in jffs2_build_remove_unlinked_inode(). However, jffs2_build_xattr_subsystem() runs later than this, and will attach an xref to the dead inode. Then later when the last nodes of that dead inode are erased we hit a BUG() in jffs2_del_ino_cache() because we're not supposed to get there with an xattr still attached to the inode which is being killed. The simple fix is to refrain from attaching xattrs to inodes with zero nlink, in jffs2_build_xattr_subsystem(). It's it's OK to trust nlink here because the file system isn't actually mounted yet, so there's no chance that a zero-nlink file could actually be alive still because it's open.

* | libata: always use polling SETXFERTejun Heo2007-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several people have reported LITE-ON LTR-48246S detection failed because SETXFER fails. It seems the device raises IRQ too early after SETXFER. This is controller independent. The same problem has been reported for different controllers. So, now we have pata_via where the controller raises IRQ before it's ready after SETXFER and a device which does similar thing. This patch makes libata always execute SETXFER via polling. As this only happens during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is also moved from issue hot path to ata_dev_set_xfermode() - the only place where SETXFER can be issued. Note that ATA_TFLAG_POLLING applies only to drivers which implement SFF TF interface and use libata HSM. More advanced controllers ignore the flag. This doesn't matter for this fix as SFF TF controllers are the problematic ones. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Moves quiesce, thread and interrupt shutdown into aacraid drivers' .shutdown handler. This fix to the aac_shutdown handler will remove the superfluous reset of the adapter during a (clean) kexec. This fix may mitigate the active investigation 'kexec and aacraid broken' but it is unlikely to affect the root cause (issue likely present in both kexec and kdump). This patch reduces the chance the problem will occur with a kexec. The fix for root cause is currently expected to be the minimum value check to the aacraid.startup_timeout driver variable after an adapter reset within aacraid_commit_reset.patch submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.

The UNIX datagram connect code blindly dereferences other->sk_socket via the call down to the security_unix_may_send() function. Without locking 'other' that pointer can go NULL via unix_release_sock() which does sock_orphan() which also marks the socket SOCK_DEAD. So we have to lock both 'sk' and 'other' yet avoid all kinds of potential deadlocks (connect to self is OK for datagram sockets and it is possible for two datagram sockets to perform a simultaneous connect to each other). So what we do is have a "double lock" function similar to how we handle this situation in other areas of the kernel. We take the lock of the socket pointer with the smallest address first in order to avoid ABBA style deadlocks. Once we have them both locked, we check to see if SOCK_DEAD is set for 'other' and if so, drop everything and retry the lookup. Signed-off-by: David S. Miller <davem@davemloft.net>

With these 2 flags set, the link status is polled by tg3_timer() and will only work when the PHY is set up to interrupt the MAC on link changes. This breaks 5906 because the 5906 PHY does not support TG3_FLAG_USE_MI_INTERRUPT the same as other PHYs. For correctness, only Dell's onboard 5701 needs these 2 flags to be set. This change will fix the 5906 problem and will change other Dell devices except 5700 and 5701 to use the more efficient interrupt-driven link changes. Update version to 3.77.
