The SMSC911x driver resets the ->head, ->data and ->tail pointers in the
skb on the reset path in order to avoid buffer overflow due to packet
padding performed by the hardware.
This patch fixes the receive path so that the skb pointers are fixed up
after the data has been read from the device, The error path is also
fixed to use number of words consistently and prevent erroneous FIFO
fastforwarding when skipping over bad data.

The scratch register addresses have been changed for newer chips.
Since the old chip was never shipped and it will not be supported
any more, just update register addresses to support the new chips.

There have been reports about not being able to use access-points
on channel 12 and 13 or having connectivity issues when these channels
were part of the selected regulatory domain. Upon switching to these
channels the brcmsmac driver suspends the transmit dma fifos. This
patch resumes them upon handing over the first received beacon to
mac80211.
This patch is to be applied to the stable tree for kernel versions
3.2 and 3.3.

We set intr mask before its handler is registered, this does not work well when
8139cp is sharing irq line with other devices. As the irq could be enabled by
the device before 8139cp's hander is registered which may lead unhandled
irq. Fix this by introducing an helper cp_irq_enable() and call it after
request_irq().

Problem:
There was two separate work_struct structures which share one
handler. Unfortunately getting atl1_adapter structure from
work_struct in case of DMA error was done from incorrect
offset which cause kernel panics.
Solution:
The useless work_struct for DMA error removed and
handler name changed to more generic one.

Commit e675f0cc9a872fd152edc0c77acfed19bf28b81e ("ppp: Don't stop and
restart queue on every TX packet") introduced a race condition which
could leave the net queue stopped even when the channel is no longer
busy. By calling netif_stop_queue() from ppp_start_xmit(), based on the
return value from ppp_xmit_process() but *after* all the locks have been
dropped, we could potentially do so *after* the channel has actually
finished transmitting and attempted to re-wake the queue.
Fix this by moving the netif_stop_queue() into ppp_xmit_process() under
the xmit lock. I hadn't done this previously, because it gets called
from other places than ppp_start_xmit(). But I now think it's the better
option. The net queue *should* be stopped if the channel becomes
congested due to writes from pppd, anyway.

If the ipv6 dst cache which copy from the dst generated by ICMPV6 RA packet.
this dst cache will not check expire because it has no RTF_EXPIRES flag.
So this dst cache will always be used until the dst gc run.
Change the struct dst_entry,add a union contains new pointer from and expires.
When rt6_info.rt6i_flags has no RTF_EXPIRES flag,the dst.expires has no use.
we can use this field to point to where the dst cache copy from.
The dst.from is only used in IPV6.
rt6_check_expired check if rt6_info.dst.from is expired.
ip6_rt_copy only set dst.from when the ort has flag RTF_ADDRCONF
and RTF_DEFAULT.then hold the ort.
ip6_dst_destroy release the ort.
Add some functions to operate the RTF_EXPIRES flag and expires(from) together.
and change the code to use these new adding functions.
Changes from v5:
modify ip6_route_add and ndisc_router_discovery to use new adding functions.
Only set dst.from when the ort has flag RTF_ADDRCONF
and RTF_DEFAULT.then hold the ort.

After investigation it turns out there were two issues.
1) Phonet was not implementing network devices but was using register_pernet_device
instead of register_pernet_subsys.
This was allowing there to be cases when phonenet was not initialized and
the phonet net_generic was not set for a network namespace when network
device events were being reported on the netdevice_notifier for a network
namespace leading to the oops above.
2) phonet_exit_net was implementing a confusing and special case of handling all
network devices from going away that it was hard to see was correct, and would
only occur when the phonet module was removed.
Now that unregister_netdevice_notifier has been modified to synthesize unregistration
events for the network devices that are extant when called this confusing special
case in phonet_exit_net is no longer needed.

We already synthesize events in register_netdevice_notifier and synthesizing
events in unregister_netdevice_notifier allows to us remove the need for
special case cleanup code.
This change should be safe as it adds no new cases for existing callers
of unregiser_netdevice_notifier to handle.

Commit 94e5a85b ("ARM: earlier initialization of vectors page") made it
the responsibility of paging_init to initialise the vectors page.
This patch adds a call to early_trap_init for the !CONFIG_MMU case,
placing the vectors at CONFIG_VECTORS_BASE.

The description for the CPU_HIGH_VECTOR Kconfig option for nommu builds
doesn't make any sense.
This patch fixes up the trivial grammatical error.

Some bootloaders are broken enough to expose an ATAG_MEM with
a null size. Converting such tag to a memory node leads to
an unbootable system.
Skip over zero sized ATAG_MEM to avoid this situation.

atags_to_fdt() returns 1 when it fails to find a valid FDT signature.
The CONFIG_ARM_ATAG_DTB_COMPAT code is supposed to retry with another
location, but only does so when the initial call doesn't fail.
Fix this by using the correct condition in the assembly code.

The AMBA bus regulator support is being used to model on/off switches
for power domains which isn't terribly idiomatic for modern kernels with
the generic power domain code and creates integration problems on platforms
which don't use regulators for their power domains as it's hard to tell
the difference between a regulator that is needed but failed to be provided
and one that isn't supposed to be there (though DT does make that easier).
Platforms that wish to use the regulator API to manage their power domains
can indirect via the power domain interface.
This feature is only used with the vape supply of the db8500 PRCMU
driver which supplies the UARTs and MMC controllers, none of which have
support for managing vcore at runtime in mainline (only pl022 SPI
controller does). Update that supply to have an always_on constraint
until the power domain support for the system is updated so that it is
enabled for these users, this is likely to have no impact on practical
systems as probably at least one of these devices will be active and
cause AMBA to hold the supply on anyway.

interface
The clocks for all DSS slave interfaces were recently changed to "dss_ick" on
OMAP2 and OMAP3, this clock can be autoidled by PRCM. The VENC interface
previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and
hence the OCPIF_SWSUP_IDLE flag was needed.
Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is
now "dss_ick". This allows the PRCM hardware to autoidle the VENC
interface clocks when they are not active, rather than relying on the
software to do it, which can keep the interface clocks active
unnecessarily.
