When a PCI device driver does not support PCI error recovery, the powerpc/pseries code takes a walk through a branch of code that resets the failure counter. Because of this, if a broken PCI card is present, the kernel will attempt to reset it an infinite number of times. (This is annoying but mostly harmless: each reset takes about 10-20 seconds, and uses almost no CPU time). This patch preserves the failure count across resets.

This patch fixes hello messages sent when a node is a level 1 router. Slightly contrary to the spec (maybe) VMS ignores hello messages that do not name level2 routers that it also knows about. So, here we simply name all the routers that the node knows about rather just other level1 routers. (I hope the patch is clearer than the description. sorry).

Calling sock_orphan inside bh_lock_sock in tcp_close can lead to dead locks. For example, the inet_diag code holds sk_callback_lock without disabling BH. If an inbound packet arrives during that admittedly tiny window, it will cause a dead lock on bh_lock_sock. Another possible path would be through sock_wfree if the network device driver frees the tx skb in process context with BH enabled. We can fix this by moving sock_orphan out of bh_lock_sock. The tricky bit is to work out when we need to destroy the socket ourselves and when it has already been destroyed by someone else. By moving sock_orphan before the release_sock we can solve this problem. This is because as long as we own the socket lock its state cannot change. So we simply record the socket state before the release_sock and then check the state again after we regain the socket lock. If the socket state has transitioned to TCP_CLOSE in the time being, we know that the socket has been destroyed. Otherwise the socket is still ours to keep. Note that I've also moved the increment on the orphan count forward. This may look like a problem as we're increasing it even if the socket is just about to be destroyed where it'll be decreased again. However, this simply enlarges a window that already exists. This also changes the orphan count test by one. Considering what the orphan count is meant to do this is no big deal. This problem was discoverd by Ingo Molnar using his lock validator.

When a Choice element contains an unsupported choice no error is returned and parsing continues normally, but the choice value is not set and contains data from the last parsed message. This may in turn lead to parsing of more stale data and following crashes.

Address the issue of EDAC/BIOS coexistence for the e752x chip-sets. We have found a problem where the BIOS will start the system with the error registers (dev0:fun1) hidden and assuming it has exclusive access to them. The edac driver violates this assumption. The workaround this patch offers is to honor the hidden-ness as an indication that it is not safe to use those registers.
