When /proc/sys/vm/oom_kill_allocating_task is set for large systems that
want to avoid the lengthy tasklist scan, it's possible to livelock if
current is ineligible for oom kill. This normally happens when it is set
to OOM_DISABLE, but is also possible if any threads are sharing the same
->mm with a different tgid.
So change __out_of_memory() to fall back to the full task-list scan if it
was unable to kill `current'.

Fix a problem where the generic block based fiemap stuff would not
properly set FIEMAP_EXTENT_LAST on the last extent. I've reworked things
to keep track if we go past the EOF, and mark the last extent properly.
The problem was reported by and tested by Eric Sandeen.

When building with gcc 3.2 I get thousands of warnings such as
include/linux/gfp.h: In function `allocflags_to_migratetype':
include/linux/gfp.h:105: warning: null format string
due to passing a NULL format string to warn_slowpath() in
#define __WARN() warn_slowpath(__FILE__, __LINE__, NULL)
Split this case out into a separate call. This also shrinks the kernel
slightly:
text data bss dec hex filename
4802274 707668 712704 6222646 5ef336 vmlinux
text data bss dec hex filename
4799027 703572 712704 6215303 5ed687 vmlinux
due to removeing one argument from the commonly-called __WARN().

There is what we believe to be a false positive reported by lockdep.
inotify_inode_queue_event() => take inotify_mutex => kernel_event() =>
kmalloc() => SLOB => alloc_pages_node() => page reclaim => slab reclaim =>
dcache reclaim => inotify_inode_is_dead => take inotify_mutex => deadlock
The plan is to fix this via lockdep annotation, but that is proving to be
quite involved.
The patch flips the allocation over to GFP_NFS to shut the warning up, for
the 2.6.30 release.
Hopefully we will fix this for real in 2.6.31. I'll queue a patch in -mm
to switch it back to GFP_KERNEL so we don't forget.

When a new wimax_dev is created, it's state has to be __WIMAX_ST_NULL
until wimax_dev_add() is succesfully called. This allows calls into
the stack that happen before said time to be rejected.
Until now, the state was being set (by mistake) to UNINITIALIZED,
which was allowing calls such as wimax_report_rfkill_hw() to go
through even when a call to wimax_dev_add() had failed; that was
causing an oops when touching uninitialized data.
This situation is normal when the device starts reporting state before
the whole initialization has been completed. It just has to be dealt
with.

When sending a message to user space using wimax_msg(), if nla_put()
fails, correctly interpret the return code from wimax_msg_alloc() as
an err ptr and return the error code instead of crashing (as it is
assuming than non-NULL means the pointer is ok).

madvise(MADV_WILLNEED) forces page cache readahead on a range of memory
backed by a file. The assumption is made that the page required is
order-0 and "normal" page cache.
On hugetlbfs, this assumption is not true and order-0 pages are
allocated and inserted into the hugetlbfs page cache. This leaks
hugetlbfs page reservations and can cause BUGs to trigger related to
corrupted page tables.
This patch causes MADV_WILLNEED to be ignored for hugetlbfs-backed
regions.

Setting the name of a sysfs device has to be done in a context that can
actually sleep. It allocates its memory with GFP_KERNEL. Previously it
was a static (size limited) string and that got changed to accommodate
longer device names. So move the dev_set_name() just before calling
device_add() which is executed in a work queue.
This fixes the following error:

When an upstream port reports an AER error to root port, kernel
starts error recovery procedures. The default return value of
function pcie_portdrv_slot_reset is PCI_ERS_RESULT_NONE. If all
port service drivers of the downstream port under the upstream
port have no slot_reset method in pci_error_handlers, AER recovery
would stop without resume. Below patch against 2.6.30-rc3 fixes it.

disable_irq() should wait for all running handlers to complete
before returning. As such, if it's used to disable an interrupt
from that interrupt's handler it will deadlock. This replaces
the dangerous instances with the _nosync() variant which doesn't
have this problem.
Note the 2 handlers in question are only used #ifdef DEBUG so
I imagine these code paths don't get hit often.

This patch fixes the wrong message type that are triggered by
user updates, the following commands:
(term1)# conntrack -I -p tcp -s 1.1.1.1 -d 2.2.2.2 -t 10 --sport 10 --dport 20 --state LISTEN
(term1)# conntrack -U -p tcp -s 1.1.1.1 -d 2.2.2.2 -t 10 --sport 10 --dport 20 --state SYN_SENT
(term1)# conntrack -U -p tcp -s 1.1.1.1 -d 2.2.2.2 -t 10 --sport 10 --dport 20 --state SYN_RECV
only trigger event message of type NEW, when only the first is NEW
while others should be UPDATE.
(term2)# conntrack -E
[NEW] tcp 6 10 LISTEN src=1.1.1.1 dst=2.2.2.2 sport=10 dport=20 [UNREPLIED] src=2.2.2.2 dst=1.1.1.1 sport=20 dport=10 mark=0
[NEW] tcp 6 10 SYN_SENT src=1.1.1.1 dst=2.2.2.2 sport=10 dport=20 [UNREPLIED] src=2.2.2.2 dst=1.1.1.1 sport=20 dport=10 mark=0
[NEW] tcp 6 10 SYN_RECV src=1.1.1.1 dst=2.2.2.2 sport=10 dport=20 [UNREPLIED] src=2.2.2.2 dst=1.1.1.1 sport=20 dport=10 mark=0
This patch also removes IPCT_REFRESH from the bitmask since it is
not of any use.

This patch fixes a problem when you use 32 nodes in the cluster
match:
% iptables -I PREROUTING -t mangle -i eth0 -m cluster \
--cluster-total-nodes 32 --cluster-local-node 32 \
--cluster-hash-seed 0xdeadbeef -j MARK --set-mark 0xffff
iptables: Invalid argument. Run `dmesg' for more information.
% dmesg | tail -1
xt_cluster: this node mask cannot be higher than the total number of nodes
The problem is related to this checking:
if (info->node_mask >= (1 << info->total_nodes)) {
printk(KERN_ERR "xt_cluster: this node mask cannot be "
"higher than the total number of nodes\n");
return false;
}
(1 << 32) is 1. Thus, the checking fails.
BTW, I said this before but I insist: I have only tested the cluster
match with 2 nodes getting ~45% extra performance in an active-active setup.
The maximum limit of 32 nodes is still completely arbitrary. I'd really
appreciate if people that have more nodes in their setups let me know.
