The strchrnul() variant helpfully returns a the end of the string
instead of a NULL if the requested character is not found. This can
simplify string parsing code since it doesn't need to expicitly check
for a NULL return. If a valid string pointer is passed in, then a valid
null terminated string will always come back out.

Reduce and clarify locking requirements for ovs_flow_cmd_alloc_info(),
ovs_flow_cmd_fill_info() and ovs_flow_cmd_build_info().
A datapath pointer is available only when holding a lock. Change
ovs_flow_cmd_fill_info() and ovs_flow_cmd_build_info() to take a
dp_ifindex directly, rather than a datapath pointer that is then
(only) used to get the dp_ifindex. This is useful, since the
dp_ifindex is available even when the datapath pointer is not, both
before and after taking a lock, which makes further critical section
reduction possible.
Make ovs_flow_cmd_alloc_info() take an 'acts' argument instead a
'flow' pointer. This allows some future patches to do the allocation
before acquiring the flow pointer.
The locking requirements after this patch are:
ovs_flow_cmd_alloc_info(): May be called without locking, must not be
called while holding the RCU read lock (due to memory allocation).
If 'acts' belong to a flow in the flow table, however, then the
caller must hold ovs_mutex.
ovs_flow_cmd_fill_info(): Either ovs_mutex or RCU read lock must be held.
ovs_flow_cmd_build_info(): This calls both of the above, so the caller
must hold ovs_mutex.

Move most memory allocations away from the ovs_mutex critical

changing that would require major refactoring. Also, vports are
created very rarely so it should not matter.

Minimize padding in sw_flow_key and move 'tp' top the main struct.
These changes simplify code when accessing the transport port numbers
and the tcp flags, and makes the sw_flow_key 8 bytes smaller on 64-bit
systems (128->120 bytes). These changes also make the keys for IPv4
packets to fit in one cache line.
There is a valid concern for safety of packing the struct
ovs_key_ipv4_tunnel, as it would be possible to take the address of
the tun_id member as a __be64 * which could result in unaligned access
in some systems. However:
- sw_flow_key itself is 64-bit aligned, so the tun_id within is
always
64-bit aligned.
- We never make arrays of ovs_key_ipv4_tunnel (which would force
every
second tun_key to be misaligned).
- We never take the address of the tun_id in to a __be64 *.
- Whereever we use struct ovs_key_ipv4_tunnel outside the
sw_flow_key,
it is in stack (on tunnel input functions), where compiler has full
control of the alignment.

the internal reference design for boards based on Freescale's
P2040/P2041 SoCs. This internal reference design is named kmp204x.
The peripherals used on this board are:
- SPI NOR Flash as bootloader medium
- NAND Flash with a ubi partition
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 4 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
CPLD
- 2 I2C busses
- last but not least, the mandatory serial port
The patch also adds a defconfig file for this reference design that is
necessary because of the lowmem option that must be set higher due to

The way the driver core is implemented, every device using the same bus
type is required to have a unique name because a symlink to each device
is created in the appropriate /sys/bus/*/devices directory, and two
identical names causes a collision.
The current code handles the requirement by using an globally
incremented counter that is appended to the device name. It works, but
it means any change to device registration will change the assigned
numbers. Instead, if we build up the name by using information from the
parent nodes, then it can be guaranteed to be unique without adding a
random number to the end of it.

The recent change in sysfs, bcdde7e221
"sysfs: make __sysfs_remove_dir() recursive" revealed an asymmetric
rphy device creation/deletion sequence in scsi_transport_sas:
modprobe mpt2sas
sas_rphy_add
device_add A rphy->dev
device_add B sas_device transport class
device_add C sas_end_device transport class
device_add D bsg class
rmmod mpt2sas
sas_rphy_delete
sas_rphy_remove
device_del B
device_del C
device_del A
sysfs_remove_group recursive sysfs dir removal
sas_rphy_free
device_del D warning
where device A is the parent of B, C, and D.
When sas_rphy_free tries to unregister the bsg request queue (device D
above), the ensuing sysfs cleanup discovers that its sysfs group has
already been removed and emits a warning, "sysfs group... not found for
kobject 'end_device-X:0'".
Since bsg creation is a side effect of sas_rphy_add, move its
complementary removal call into sas_rphy_remove. This imposes the
following tear-down order for the devices above: D, B, C, A.
Note the sas_device and sas_end_device transport class devices (B and C
above) are created and destroyed both via the list match traversal in
attribute_container_device_trigger, so the order in which they are
handled is fixed. This is fine as long as they are deleted before their
parent device.

drivers/pinctrl/sunxi/Kconfig:3:error: recursive dependency detected!
drivers/pinctrl/sunxi/Kconfig:3: symbol PINCTRL_SUNXI is selected by PINCTRL_SUN4I_A10
drivers/pinctrl/sunxi/Kconfig:9: symbol PINCTRL_SUN4I_A10 default value contains PINCTRL_SUNXI
Add a new intermedia PINCTRL_SUNXI_COMMON, that superseeds the PINCTRL_SUNXI
one.
We still need to keep PINCTRL_SUNXI at the moment in order to preserve
bisectability. Indeed, during that merge window, we also introduced the
MACH_SUN* symbols. Since it's going through different trees, we can't rely on
the fact that the options will be there, while ARCH_SUNXI still select
PINCTRL_SUNXI.
