If you undefine all the early debugging options and then run make oldconfig,
you don't get prompted to see if you want to enable any of them. This is
annoying.
AFAICT we can't do this just with a choice, because the choice is either
optional, in which case we don't get prompted, or not in which case we _must_
select early debugging.
So add a bool which controls whether we have early debugging at all, and then
if that's enabled provide the choice. The extra bool will actually be useful
in another patch I have lying around, so this is a win-win.

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.

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.
