MIPS: PCI: Reduce stack frame usage

2016-10-04T14:13:57+00:00

This patch removes creating a fake pci device in MIPS early config
access and instead just uses the pci bus to get the same functionality.
The struct pci_dev is too large to allocate on the stack, and was relying
on compiler optimizations to remove its usage.

MIPS: TXx9: Convert to Common Clock Framework

2016-10-04T14:13:57+00:00

Replace the custom minimal clock implementation for Toshiba TXx9 by a
basic implementation using the Common Clock Framework.

The only clocks that are provided are those needed by TXx9-specific
drivers ("imbus" and "spi" (TX4938 only)), and their common parent
clock "gbus". Other clocks can be added when needed.

MIPS: TXx9: tx49xx: Move GPIO setup from .mem_setup() to .arch_init()

2016-10-04T14:13:57+00:00

txx9_gpio_init() calls gpiochip_add_data(), which fails with -ENOMEM as
it is called too early in the boot process. This causes all subsequent
GPIO operations to fail silently (before commit 54d77198fdfbc4f0 ("gpio:
bail out silently on NULL descriptors") it printed the error message
"gpiod_direction_output_raw: invalid GPIO" on RBTX49[23]7).

Postpone all GPIO setup to .arch_init() time to fix this.

treewide: replace obsolete _refok by __ref

2016-08-02T21:31:41+00:00

There was only one use of __initdata_refok and __exit_refok

__init_refok was used 46 times against 82 for __ref.

Those definitions are obsolete since commit 312b1485fb50 ("Introduce new
section reference annotations tags: __ref, __refdata, __refconst")

This patch removes the following compatibility definitions and replaces
them treewide.

/* compatibility defines */
#define __init_refok     __ref
#define __initdata_refok __refdata
#define __exit_refok     __ref

I can also provide separate patches if necessary.
(One patch per tree and check in 1 month or 2 to remove old definitions)

Pull networking updates from David Miller:
 "Highlights:

   1) Support more Realtek wireless chips, from Jes Sorenson.

   2) New BPF types for per-cpu hash and arrap maps, from Alexei
      Starovoitov.

   3) Make several TCP sysctls per-namespace, from Nikolay Borisov.

   4) Allow the use of SO_REUSEPORT in order to do per-thread processing
   of incoming TCP/UDP connections.  The muxing can be done using a
   BPF program which hashes the incoming packet.  From Craig Gallek.

   5) Add a multiplexer for TCP streams, to provide a messaged based
      interface.  BPF programs can be used to determine the message
      boundaries.  From Tom Herbert.

   6) Add 802.1AE MACSEC support, from Sabrina Dubroca.

   7) Avoid factorial complexity when taking down an inetdev interface
      with lots of configured addresses.  We were doing things like
      traversing the entire address less for each address removed, and
      flushing the entire netfilter conntrack table for every address as
      well.

   8) Add and use SKB bulk free infrastructure, from Jesper Brouer.

   9) Allow offloading u32 classifiers to hardware, and implement for
      ixgbe, from John Fastabend.

  10) Allow configuring IRQ coalescing parameters on a per-queue basis,
      from Kan Liang.

  11) Extend ethtool so that larger link mode masks can be supported.
      From David Decotigny.

  12) Introduce devlink, which can be used to configure port link types
      (ethernet vs Infiniband, etc.), port splitting, and switch device
      level attributes as a whole.  From Jiri Pirko.

  13) Hardware offload support for flower classifiers, from Amir Vadai.

  14) Add "Local Checksum Offload".  Basically, for a tunneled packet
      the checksum of the outer header is 'constant' (because with the
      checksum field filled into the inner protocol header, the payload
      of the outer frame checksums to 'zero'), and we can take advantage
      of that in various ways.  From Edward Cree"

This makes the driver use the data pointer added to the gpio_chip

container_of().
