s3c24xx implements its own inb/outb macros, but the implementation
prints warnings when the port number argument is not a 32-bit scalar:

As of 9b5ba0df4e ("ARM: shmobile: Introduce ARCH_RENESAS") all platforms
that use Renesas clock drivers now select ARCH_RENESAS. As it is present in
drivers/clk/Makefile ARCH_SHMOBILE_MULTI may now be removed.
This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more

The core clock does not depend on corediv, so enabling corediv
based on the clock is not really correct. Move the corediv
config option from the clock driver Kconfig to the mvebu Kconfig
so that it can be enabled by the MACH option instead.
This also enables corediv on Armada 375 and 38X, which was
previously missing.

Despite care take to allocate clocks state containers the
SP810 driver actually just supports creating one instance:
all clocks registered for every instance will end up with the
exact same name and __clk_init() will fail.
Rename the timclken<0> .. timclken<n> to sp810_<instance>_<n>
so every clock on every instance gets a unique name.
This is necessary for the RealView PBA8 which has two SP810
blocks: the second block will not register its clocks unless
every clock on every instance is unique and results in boot
logs like this:

When the TIPC module is unloaded, we have identified a race condition
that allows a node reference counter to go to zero and the node instance
being freed before the node timer is finished with accessing it. This
leads to occasional crashes, especially in multi-namespace environments.
The scenario goes as follows:
CPU0:(node_stop) CPU1:(node_timeout) // ref == 2
1: if(!mod_timer())
2: if (del_timer())
3: tipc_node_put() // ref -> 1
4: tipc_node_put() // ref -> 0
5: kfree_rcu(node);
6: tipc_node_get(node)
7: // BOOM!
We now clean up this functionality as follows:
1) We remove the node pointer from the node lookup table before we
attempt deactivating the timer. This way, we reduce the risk that
tipc_node_find() may obtain a valid pointer to an instance marked
for deletion; a harmless but undesirable situation.
2) We use del_timer_sync() instead of del_timer() to safely deactivate
the node timer without any risk that it might be reactivated by the
timeout handler. There is no risk of deadlock here, since the two
functions never touch the same spinlocks.
3: We remove a pointless tipc_node_get() + tipc_node_put() from the
timeout handler.

Although we have never seen it happen, we have identified the
following problematic scenario when nodes are stopped and deleted:
CPU0: CPU1:
tipc_node_xxx() //ref == 1
tipc_node_put() //ref -> 0
tipc_node_find() // node still in table
tipc_node_delete()
list_del_rcu(n. list)
tipc_node_get() //ref -> 1, bad
kfree_rcu()
tipc_node_put() //ref to 0 again.
kfree_rcu() // BOOM!
We fix this by introducing use of the conditional kref_get_if_not_zero()
instead of kref_get() in the function tipc_node_find(). This eliminates
any risk of post-mortem access.

The id buffer in ata_device is a DMA target, but it isn't explicitly
cacheline aligned. Due to this, adjacent fields can be overwritten with
stale data from memory on non coherent architectures. As a result, the
kernel is sometimes unable to communicate with an ATA device.
Fix this by ensuring that the id buffer is cacheline aligned.

There will be a log spam when there is no cable plugged. Please refer to
following links. https://bugzilla.kernel.org/show_bug.cgi?id=104351https://bugzilla.kernel.org/show_bug.cgi?id=107421
This issue is caused by runtime power management. When there is no cable
plugged, the driver will be suspend (runtime suspend) by OS and NIC will be
put into the D3 state. During this time, if OS call rtl8169_get_stats64()
to dump tally counter, because NIC is in D3 state, the register value read
by driver will return all 0xff. This will let driver think tally counter
flag is not toggled and then sends the warning message "rtl_counters_cond
== 1 (loop: 1000, delay: 10)" to kernel log.
For fixing this issue, 1.add checking driver's pm runtime status in
rtl8169_get_stats64(). 2.dump tally counter before going runtime suspend
for counter accuracy in runtime suspend.

The PCI config header (first 64 bytes of each device's config space) is
defined by the PCI spec so generic software can identify the device and
manage its usage of I/O, memory, and IRQ resources.
Some non-spec-compliant devices put registers other than BARs where the
BARs should be. When the PCI core sizes these "BARs", the reads and writes
it does may have unwanted side effects, and the "BAR" may appear to
describe non-sensical address space.
Add a flag bit to mark non-compliant devices so we don't touch their BARs.
Turn off IO/MEM decoding to prevent the devices from consuming address
space, since we can't read the BARs to find out what that address space
would be.

net: dsa: add port VLAN dump operation
The VLAN GetNext approach is specific to some switches and thus hard to
implement for others. This patchset replaces it with a simpler port VLAN dump
operation, similar to the corresponding FDB operation.
The mv88e6xxx driver is the only one currently affected by the change.
The documentation is updated accordingly.
Note: this patchset uses http://www.spinics.net/lists/kernel/msg2186705.html
