Nicolas Ferre 7c39994fc1 net/macb: add the user i/o to ethtool register dump
User i/o register EMAC_USRIO or GMAC_UR can be found on both macb and gem
flavors of the peripheral. By using the proper accessor, we can add it to the
register dump feature of ethtool.
Increment the version of this API so it can be noticed from user space.

Nicolas Ferre c69618b3e4 net/macb: fix probe sequence to setup clocks earlier
As accessing the peripheral registers need the clocks to be set, we have to
enable them as soon as possible. Their configuration depend on the type of
device used and determined by the DT compatible string. That lead to add
another initialization function in the DT configuration structure.
As the device private structure length depend on an information read in the
registers, we have to store the clock pointers in temporary variables before
feeding the structure fields.

Nicolas Ferre f6970505de net/macb: fix capabilities configuration
Capabilities configuration by macb_configure_caps() was moved far too late by
421d9df062 (net/macb: merge at91_ether driver into macb driver) which would
lead to badly configured hardware.
So, move this function to early probe and modify its prototype to re-gain its
original behavior.
DT data retrieval is also moved to simplify the probe code flow.

Nicolas Ferre bfa0914afa net/macb: only probe queues once and use stored values
When merging at91_ether and macb driver during 421d9df062 (net/macb: merge
at91_ether driver into macb driver) the probe function has been split. The code
dealing with initialization of queues is now moved in macb_init() which needs
information computed in the parent macb_probe() function.
So, add the queue_mask information to the private structure and use it when
needed in macb_init().

====================
netlink: access functions for IP address attributes

There are many places that read or write IP addresses to netlink attributes.
With IPv6 addresses, every such place currently has to use generic nla_put
and nla_memcpy. Implementing IPv6 address access functions simplify things
and makes the code more intelligible. IPv4 address access functions has
lesser value but it would be better to be consistent between IPv6 and IPv4
and they still serve as documentation.

The conversion is straightforward and the resulting patches are not that
large, thus I kept all the changes in the patches that introduce the access
functions. If anyone prefers to split the definition of access functions and
the conversion and/or break it out by network protocols, please let me know.

While doing the conversion, I came across ugly typecasting in
inetpeer_addr_base and xfrm_address_t when dealing with IPv6 addresses.
Instead of introducing more of this, I cleaned it up. Those are the first
two patches, serving as a prerequisite to the latter two.

The issue was that as a part of exiting the default rules were being
deleted which resulted in the local trie being unmerged.  By moving the
freeing of the FIB tables up we can avoid the unmerge since there is no
local table left when we call the fib4_rules_exit function.

Johan Hedberg says:

====================
pull request: bluetooth-next 2015-03-27

Here's another set of Bluetooth & 802.15.4 patches for 4.1:

 - New API to control LE advertising data (i.e. peripheral role)
 - mac802154 & at86rf230 cleanups
 - Support for toggling quirks from debugfs (useful for testing)
 - Memory leak fix for LE scanning
 - Extra version info reading support for Broadcom controllers

Please let me know if there are any issues pulling. Thanks.

David S. Miller 32eaf120e6 Merge branch 'ptp-2038'
Fixed two warnings in e1000e and igb, when switching to timespec64
some printf formats started to not match.  In theses cases actually
the new type is __kernel_time_t which is __kernel_long_t which
unfortunately can be either "long" or "long long".  So to solve
this I cases the arguments to "long long".  -DaveM

ptp: get ready for 2038

This series converts the core driver methods of the PTP Hardware Clock
(PHC) subsystem to use the 64 bit version of the timespec structure,
making the core API ready for the year 2038.

In addition, I reviewed how each driver and device represents the time
value at the hardware register level.  Most of the drivers are ready,
but a few will need some work before the year 2038, as shown:

   Patch   Driver
   ------------------------------------------------
   12      drivers/net/ethernet/intel/igb/igb_ptp.c
   15 ?    drivers/net/ethernet/sfc/ptp.c
   16      drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c

The commit log messages document how each driver is ready or why it is
not ready.  For patch 15, I could not easily find out the hardware
representation of the time value, and so the SFC maintainers will have
to review their low level code in order to resolve any remaining
issues.

* ChangeLog
** V3
   - dp83640: use timespec64 throughout per Arnd's suggestion
   - tilegx: use timespec64 throughout per Chris' suggestion
   - add Jeff's acked-bys
** V2
   - use the new methods in the posix clock code right away (patch #3)

Richard Cochran ed7c6317bc ptp: remove 32 bit get/set methods.
All of the PHC drivers have been converted to the new methods.  This patch
converts the three remaining callers within the core code and removes the
older methods for good.  As a result, the core PHC code is ready for the
year 2038.  However, some of the PHC drivers are not quite ready yet.

Richard Cochran a043a72909 ptp: pch: convert to the 64 bit get/set time methods.
The device has a 64 bit clock register, where each clock tick is 32
nanoseconds, and so with this patch the driver is ready for the year
2038.

Compile tested only.

Richard Cochran 41c2c18ffb ptp: dp83640: convert to the 64 bit get/set time methods.
This device stores the number of seconds in a 32 bit register, and the
stored value is unsigned.  Therefore this driver and device are ready
for the year 2038.  However, more work will be needed prior to 2106.

Compile tested only.

Richard Cochran b9acf24f77 ptp: tilegx: convert to the 64 bit get/set time methods.
This driver is 64 bit only, and so this driver and device are ready
for 2038.  This patch changes the driver to the new PHC and also
carries the timespec64 parameter on out to the gxio_mpipe_get-
set_timestamp functions, making explicit the fact that the tv_sec
field is 64 bits wide.

Not even compile tested.
