485a2d54db [PATCH] powerpc: Make early debugging options behave with oldconfig
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.

b26f100d89 [PATCH] powerpc: remove do-nothing cpu setup routines
Removed the do-nothing routines __setup_cpu_power3 and
__setup_cpu_power4 and replaced them with a null pointer check
in the caller.  Also removed the Cell processor specific
routine __setup_cpu_be which improperly accessed the
hypervisor page size configuration at SPR HID6.

4240545661 [PATCH] powerpc/pseries: Increment fail counter in PCI recovery
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

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).

75c2d9077c [TCP]: Fix sock_orphan dead lock
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.

We have found a problem where the BIOS will start the system with the error

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.

d205819e23 [PATCH] powerpc: Use the ibm,pa-features property if available
Forthcoming IBM machines will have a "ibm,pa-features" property on CPU
nodes, that contains bits indicating which optional architecture
features are implemented by the CPU.  This adds code to use the
property, if present, to update our CPU feature bitmaps.  Note that
this means we can both set and clear feature bits based on what
the firmware tells us.

This is based on a patch by Will Schmidt <willschm@us.ibm.com>.

6bfd93c32a powerpc: Fix incorrect might_sleep in __get_user/__put_user on kernel addresses
We have a case where __get_user and __put_user can validly be used
on kernel addresses in interrupt context - namely, the alignment
exception handler, as our get/put_unaligned just do a single access
and rely on the alignment exception handler to fix things up in the
rare cases where the cpu can't handle it in hardware.  Thus we can
get alignment exceptions in the network stack at interrupt level.
The alignment exception handler does a __get_user to read the
instruction and blows up in might_sleep().

Since a __get_user on a kernel address won't actually ever sleep,
this makes the might_sleep conditional on the address being less
than PAGE_OFFSET.

6e1976961c [PATCH] ppc32 CPM_UART: fixes and improvements
A number of small issues are fixed, and added the header file, missed from the
original series. With this, driver should be pretty stable as tested among
both platform-device-driven and "old way" boards. Also added missing GPL
statement , and updated year field on existing ones to reflect
code update.

61f5657c50 [PATCH] ppc32 CPM_UART: Fixed break send on SCC
SCC uart sends a break sequence each time it is stopped with the
CPM_CR_STOP_TX command. That means that each time an application closes the
serial device, a break is transmitted. To fix this, graceful tx stop is
issued for SCC.

0ccde0a290 [PATCH] powerpc/kprobes: fix singlestep out-of-line
We currently single-step inline if the instruction on which a kprobe is
inserted is a trap variant.

- variants (such as tdnei, used by BUG()) typically evaluate a condition
  and cause a trap only if the condition is satisfied.
- kprobes uses the unconditional "trap" (0x7fe00008) and single-stepping
  again on this instruction, resulting in another trap without
  evaluating the condition is obviously incorrect.

054d8ff377 [PATCH] powerpc/pseries: avoid crash in PCI code if mem system not up
The powerpc code is currently performing PCI setup before memory
initialization.  PCI setup touches PCI config space registers.  If the PCI
card is bad, this will evoke an error, which currrently can't be handled,
as the PCI error recovery code expects kmalloc() to be functional.  This
patch will cause the system to punt instead of crashing with

cpu 0x0: Vector: 300 (Data Access) at [c0000000004434d0]
    pc: c0000000000c06b4: .kmem_cache_alloc+0x8c/0xf4
    lr: c00000000004ad6c: .eeh_send_failure_event+0x48/0xfc

This patch will also print name of the offending pci device.
