Implement arch specific arch_get_memory_phys_device function and
initialize phys_device for each memory section. That way we finally can
tell which piece of memory belongs to which physical device.
This makes s390's /sys/devices/system/memory/memoryX/phys_device display
the correct thing?

/sys/devices/system/memory/memoryX/phys_device is supposed to contain the
number of the physical device that the corresponding piece of memory
belongs to.
In case a physical device should be replaced or taken offline for whatever
reason it is necessary to set all corresponding memory pieces offline.
The current implementation always sets phys_device to '0' and there is no
way or hook to change that. Seems like there was a plan to implement that
but it wasn't finished for whatever reason.
So add a weak function which architectures can override to actually set
the phys_device from within add_memory_block().

jffs2 uses rb_node = NULL; to zero rb_root.
The problem with this is that 17d9ddc72fb8bba0d4f678 ("rbtree: Add
support for augmented rbtrees") in the linux-next tree adds a new field
to that struct which needs to be NULL as well. This patch uses RB_ROOT
as the intializer so all of the relevant fields will be NULL'd.

HP is recycling both DMI_PRODUCT_NAME and DMI_BIOS_VERSION making
ahci_broken_suspend() trigger for later products which are not
affected by the original problems. Match BIOS date instead of version
and add references to bko's so that full information can be found
easier later.

bko#15481 shows that we're missing some NVIDIA ahci PCI IDs. Peer
Chen confirms that IDs 0x580-0x58f are reserved for cases where Linux
ID option is selected in the BIOS and are only used for mcp65-73. Add
0x0581-0x058f.

without IGMP snooping.
Without CONFIG_BRIDGE_IGMP_SNOOPING,
BR_INPUT_SKB_CB(skb)->mrouters_only is not appropriately
initialized, so we can see garbage.
A clear option to fix this is to set it even without that
config, but we cannot optimize out the branch.
Let's introduce a macro that returns value of mrouters_only
and let it return 0 without CONFIG_BRIDGE_IGMP_SNOOPING.

route: Fix caught BUG_ON during rt_secret_rebuild_oneshot()
Call rt_secret_rebuild can cause BUG_ON(timer_pending(&net->ipv4.rt_secret_timer)) in
add_timer as there is not any synchronization for call rt_secret_rebuild_oneshot()
for the same net namespace.
Also this issue affects to rt_secret_reschedule().
Thus use mod_timer enstead.

Finally decided I should fix this. Its a straightforward inversion,
tipc_ref_acquire takes two locks in this order:
ref_table_lock
entry->lock
while tipc_deleteport takes them in this order:
entry->lock (via tipc_port_lock())
ref_table_lock (via tipc_ref_discard())
when the same entry is referenced, we get the above warning. The fix is equally
straightforward. Theres no real relation between the entry->lock and the
ref_table_lock (they just are needed at the same time), so move the entry->lock
aquisition in tipc_ref_acquire down, after we unlock ref_table_lock (this is
safe since the ref_table_lock guards changes to the reference table, and we've
already claimed a slot there. I've tested the below fix and confirmed that it
clears up the lockdep issue

This patch fixes UDP socket refcnt bugs in the pppol2tp driver.
A bug can cause a kernel stack trace when a tunnel socket is closed.
A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is
Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
pppol2tp_recv_core: sock_hold()
pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
pppol2tp_recv_core: sock_hold()
pppol2tp_recv_core: sock_put
Close tunnel management socket
pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
udp_lib_close: BUG
The addition of sock_hold() in pppol2tp_connect() solves the problem.
For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for
accepted data frames or data frames discarded because of bad UDP
checksums. This leak meant that any UDP socket that had passed L2TP
data traffic (i.e. L2TP data frames, not just L2TP control frames)
using pppol2tp would not be released by the kernel.

When transmitting L2TP frames, we derive the outgoing interface's UDP
checksum hardware assist capabilities from the tunnel dst dev. This
can sometimes be NULL, especially when routing protocols are used and
routing changes occur. This patch just checks for NULL dst or dev
pointers when checking for netdev hardware assist features.

This patch adds a driver for SMSC's LAN7500 family of USB 2.0
to gigabit ethernet adapters. It's loosely based on the smsc95xx
driver but the device registers for LAN7500 are completely different.

Implement XFS's large buffer support with the new vmap APIs. See the vmap
rewrite (db64fe02) for some numbers. The biggest improvement that comes from
using the new APIs is avoiding the global KVA allocation lock on every call.

XFS's vmap batching simply defers a number (up to 64) of vunmaps,
and keeps track of them in a list. To purge the batch, it just goes
through the list and calls vunamp on each one. This is pretty poor:
a global TLB flush is generally still performed on each vunmap, with
the most expensive parts of the operation being the broadcast IPIs
and locking involved in the SMP callouts, and the locking involved
in the vmap management -- none of these are avoided by just batching
up the calls. I'm actually surprised it ever made much difference.
(Now that the lazy vmap allocator is upstream, this description is
not quite right, but the vunmap batching still doesn't seem to do
much).
Rip all this logic out of XFS completely. I will improve vmap
performance and scalability directly in subsequent patch.

If we were to dynamically register/unregister leds and have udev or other
daemons handle the leds class uevents, we would be notified of the adding of a
new LED and if the daemon immediately tries to open one of the attributes of
the led device, it would fail with a "no such file or directory" error since
this the attributes are not yet created. Fix this by switching attributes to be
class-wide, such that the driver core will register these attributes with
device_add_attrs and then emit the kobject_uevent ADD signal.

The driver wrongly sets default state for LEDs that don't specify
default-state property.
Currently the driver handles default state this way:
memset(&led, 0, sizeof(led));
for_each_child_of_node(np, child) {
state = of_get_property(child, "default-state", NULL);
if (state) {
if (!strcmp(state, "keep"))
led.default_state = LEDS_GPIO_DEFSTATE_KEEP;
...
}
ret = create_gpio_led(&led, ...);
}
Which means that all LEDs that do not specify default-state will inherit
the last value of the default-state property, which is wrong.
This patch fixes the issue by moving LED's template initialization into
the loop body.

This patch adds an LED driver to support the Dell Activity LED on the
Dell Latitude 2100 netbook and future products to come. The Activity LED
is visible externally in the lid so classroom instructors can observe it
from a distance. The driver uses the sysfs led_class and provides a
standard LED interface.

As each led device gets registered a kernel message gets printed. In
an embedded system with a number of leds this can produce a lot
of output that just looks like noise.
Change the message type to KERN_DEBUG since it might be useful
in the dmesg output "after" booting.

The ALIX2 LED driver and the CS5535 GPIO drivers share the same I/O
range which causes a conflict if they're both enabled. Fix this for now
by adding Kconfig dependencies. While at it, also drop the EXPERIMENTAL
flag, as the code has been around for awhile already.
Note that this is a hack. At some point, a real platform support for
this board should be added which handles the LEDs via the leds-gpio
driver.
