63139885c4 phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy365 phy driver to access sysconfig register offsets via
syscfg dt property.

This is because the reg property should not be mixing address spaces
like it does currently for miphy365. This change then also aligns us
to how other platforms such as keystone and bcm7445 pass there syscon
offsets via DT.

This patch breaks DT compatibility, but this platform is considered WIP,
and is only used by a few developers who are upstreaming support for it.
This change has been done as a single atomic commit to ensure it is
bisectable.

937127fe13 phy: phy-stih407-usb: Pass sysconfig register offsets via syscfg property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the phy driver to not use the reg property to access the sysconfig
register offsets.

This is because other phy's (miphy28, miphy365) have a combination of
memory mapped registers and sysconfig control regs, and we shouldn't
be mixing address spaces in the reg property. In addition we would
ideally like the sysconfig offsets to be passed via DT in a uniform way.

This new method will also allow us to support devices which have sysconfig
registers in different banks more easily and it is also analagous to how
keystone and bcm7745 platforms pass there syscon offsets in DT.

This breaks DT compatibility, but this platform is considered WIP, and
is only used by a few developers who are upstreaming support for it.

i.MX platform maintainer Shawn Guo is not happy with the such commit as
explained below [1]:

"The GPR difference between SoCs can be encoded in device tree as well.
It's pointless to repeat the same code pattern for every single
platform, that need to set up GPR bits for enabling magic packet wake
up, while the only difference is the register and bit offset.

The platform code will become quite messy and unmaintainable if every
device driver dump their GPR register setup code into platform.

Sorry, but it's NACK from me."

This reverts commit 456062b3ec ("ARM: imx: add FEC sleep mode callback
function").

4a71d0548c Merge branch 'rhashtable-next'
Ying Xue says:

====================
Involve rhashtable_lookup_insert routine

The series aims to involve rhashtable_lookup_insert() to guarantee
that the process of lookup and insertion of an object from/into hash
table is finished atomically, allowing rhashtable's users not to
introduce an extra lock during search and insertion. For example,
tipc socket is the first user benefiting from this enhancement.

v2 changes:
 - fix the issue of waking up worker thread under a wrong condition in
   patch #2, which is pointed by Thomas.
 - move a comment from rhashtable_inser() to rhashtable_wakeup_worker()
   according to Thomas's suggestion in patch #2.
 - indent the third line of condition statement in
   rhashtable_wakeup_worker() to inner bracket in patch #2.
 - drop patch #3 of v1 series
 - fix an issue of being unable to remove an object from hash table in
   certain special case in patch #4.
 - involve a new patch #5 to avoid unnecessary wakeup for worker queue
   thread
 - involve a new patch #6 to initialize atomic "nelems" variable
 - adjust "nelem_hint" value from 256 to 192 avoiding to unnecessarily
   to shrink hash table from the beginning phase in patch #7.

v1 changes:
 But before rhashtable_lookup_insert() is involved, the following
 optimizations need to be first done:
- simplify rhashtable_lookup by reusing rhashtable_lookup_compare()
- introduce rhashtable_wakeup_worker() to further reduce duplicated
  code in patch #2
- fix an issue in patch #3
- involve rhashtable_lookup_insert(). But in this version, we firstly
  use rhashtable_lookup() to search duplicate key in both old and new
  bucket table; secondly introduce another __rhashtable_insert() helper
  function to reduce the duplicated code between rhashtable_insert()
  and rhashtable_lookup_insert().
- add patch #5 into the series as it depends on above patches. But in
  this version, no change is made comparing with its previous version.

07f6c4bc04 tipc: convert tipc reference table to use generic rhashtable
As tipc reference table is statically allocated, its memory size
requested on stack initialization stage is quite big even if the
maximum port number is just restricted to 8191 currently, however,
the number already becomes insufficient in practice. But if the
maximum ports is allowed to its theory value - 2^32, its consumed
memory size will reach a ridiculously unacceptable value. Apart from
this, heavy tipc users spend a considerable amount of time in
tipc_sk_get() due to the read-lock on ref_table_lock.

If tipc reference table is converted with generic rhashtable, above
mentioned both disadvantages would be resolved respectively: making
use of the new resizable hash table can avoid locking on the lookup;
smaller memory size is required at initial stage, for example, 256
hash bucket slots are requested at the beginning phase instead of
allocating the entire 8191 slots in old mode. The hash table will
grow if entries exceeds 75% of table size up to a total table size
of 1M, and it will automatically shrink if usage falls below 30%,
but the minimum table size is allowed down to 256.

Also converts ref_table_lock to a separate mutex to protect hash table
mutations on write side. Lastly defers the release of the socket
reference using call_rcu() to allow using an RCU read-side protected
call to rhashtable_lookup().

bd6d4db552 rhashtable: future table needs to be traversed when remove an object
When remove an object from hash table, we currently only traverse old
bucket table to check whether the object exists. If the object is not
found in it, we will try again. But in the second search loop, we still
search the object from the old table instead of future table. As a
result, the object may be not removed from hash table especially when
resizing is currently in progress and the object is just saved in the
future table.

54c5b7d311 rhashtable: introduce rhashtable_wakeup_worker helper function
Introduce rhashtable_wakeup_worker() helper function to reduce
duplicated code where to wake up worker.

By the way, as long as the both "future_tbl" and "tbl" bucket table
pointers point to the same bucket array, we should try to wake up
the resizing worker thread, otherwise, it indicates the work of
resizing hash table is not finished yet. However, currently we will
wake up the worker thread only when the two pointers point to
different bucket array. Obviously this is wrong. So, the issue is
also fixed as well in the patch.

e0d9677ea3 batman-adv: clear control block of received socket buffers
Since other network components (and some drivers) uses the control block
provided in skb's, the network coding feature might wrongly assume that
an SKB has been decoded, and thus not try to code it with another packet
again. This happens for instance when batman-adv is running on a bridge device.

Fix this by clearing the control block for every received SKB.

1fcf77c87a net/fsl: Add mEMAC MDIO support to XGMAC MDIO
The Freescale mEMAC supports operating at 10/100/1000/10G, and
its associated MDIO controller is likewise capable of operating
both Clause 22 and Clause 45 MDIO buses. It is nearly identical
to the MDIO controller on the XGMAC, so we just modify that
driver.

2f4383667d ethtool: Extend ethtool plugin module eeprom API to phylib
This patch extends the ethtool plugin module eeprom API to support cards
whose phy support is delegated to a separate driver.

The handlers for ETHTOOL_GMODULEINFO and ETHTOOL_GMODULEEEPROM call the
module_info and module_eeprom functions if the phy driver provides them;
otherwise the handlers call the equivalent ethtool_ops functions provided
by network drivers with built-in phy support.

fee7e49d45 mm: propagate error from stack expansion even for guard page
Jay Foad reports that the address sanitizer test (asan) sometimes gets
confused by a stack pointer that ends up being outside the stack vma
that is reported by /proc/maps.

This happens due to an interaction between RLIMIT_STACK and the guard
page: when we do the guard page check, we ignore the potential error
from the stack expansion, which effectively results in a missing guard
page, since the expected stack expansion won't have been done.

And since /proc/maps explicitly ignores the guard page (commit
d7824370e2: "mm: fix up some user-visible effects of the stack guard
page"), the stack pointer ends up being outside the reported stack area.

This is the minimal patch: it just propagates the error.  It also
effectively makes the guard page part of the stack limit, which in turn
measn that the actual real stack is one page less than the stack limit.

Let's see if anybody notices.  We could teach acct_stack_growth() to
allow an extra page for a grow-up/grow-down stack in the rlimit test,
but I don't want to add more complexity if it isn't needed.

07ff890dae xen-netback: fixing the propagation of the transmit shaper timeout
Since e9ce7cb6b1 ("xen-netback: Factor queue-specific data into queue struct"),
the transimt shaper timeout is always set to 0.  The value the user sets via
xenbus is never propagated to the transmit shaper.

This patch fixes the issue.
