ARM: Realview/Versatile: remove useless TIMER_RELOAD calculations
Realview/Versatile copied the Integrator timer code, including the
calculations for ensuring that the reload value fits into the 16-bit
counter. However, these platforms have a 32-bit counter which is
clocked at a slower rate.
The result is that the preprocessor conditions are never triggered:
TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than
0x10000.
So, remove the unnecessary complexity, reducing the TIMER_RELOAD
calculation to just:
TICKS_PER_uSEC * mSEC_10

Btrfs: fix the inode ref searches done by btrfs_search_path_in_tree
This is used by the inode lookup ioctl to follow all the backrefs up
to the subvol root. But the search being done would sometimes land one
past the last item in the leaf instead of finding the backref.
This changes the search to look for the highest possible backref and hop
back one item. It also fixes a leaked path on failure to find the root.

Btrfs: allow treeid==0 in the inode lookup ioctl
When a root id of 0 is sent to the inode lookup ioctl, it will
use the root of the file we're ioctling and pass the root id
back to userland along with the results.
This allows userland to do searches based on that root later on.

Btrfs: fix key checks and advance in the search ioctl
The search ioctl was working well for finding tree roots, but using it for
generic searches requires a few changes to how the keys are advanced.
This treats the search control min fields for objectid, type and offset
more like a key, where we drop the offset to zero once we bump the type,
etc.
The downside of this is that we are changing the min_type and min_offset
fields during the search, and so the ioctl caller needs extra checks to make sure
the keys in the result are the ones it wanted.
This also changes key_in_sk to use btrfs_comp_cpu_keys, just to make
things more readable.

of: Fix comparison of "compatible" properties
Commit
7c7b60cb87547b1664a4385c187f029bf514a737
"of: put default string compare and #a/s-cell values into common header"
Breaks various things on powerpc due to using strncasecmp instead of
strcasecmp for comparing against "compatible" strings.
This causes things like the 4xx PCI code to fail miserably due to the
partial matches in code like this:
for_each_compatible_node(np, NULL, "ibm,plb-pcix")
ppc4xx_probe_pcix_bridge(np);
for_each_compatible_node(np, NULL, "ibm,plb-pci")
ppc4xx_probe_pci_bridge(np);
It's not quite right to do partial name match. Entries in a compatible
list are meant to be matched whole. If a device is compatible with both
"foo" and "foo1", then the device should have both strings in its
"compatible" property.
This patch reverts powerpc and microblaze us to use strcasecmp.

The current implementation always sets phys_device to '0' and there is no

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

l2tp: Fix UDP socket reference count bugs in the pppol2tp driver
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.

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.

leds: Fix race between LED device uevent and actual attributes creation
If we were to dynamically register/unregister leds and have udev or other

new LED and if the daemon immediately tries to open one of the attributes of

this the attributes are not yet created. Fix this by switching attributes to be

leds-gpio: fix default state handling on OF platforms
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.
