Intorduced in next-20130429 and Linus has merged it

sense to replace procs with debugfs upstream.

    regulator: core: Add regulator_map_voltage_ascend() API

    A lot of regulator hardware has ascendant voltage list.
    This patch adds regulator_map_voltage_ascend() and export it.

    Drivers that have ascendant voltage list can use this as their map_voltage()
    operation, this is more efficient than default regulator_map_voltage_iterate()
    function.

    netdev: network device operations infrastructure

    This patch changes the network device internal API to move adminstrative
    operations out of the network device structure and into a separate structure.

    This patch involves some hackery to maintain compatablity between the
    new and old model, so all 300+ drivers don't have to be changed at once.
    For drivers that aren't converted yet, the netdevice_ops virt function list
    still resides in the net_device structure. For old protocols, the new
    net_device_ops are copied out to the old net_device pointers.

    After the transistion is completed the nag message can be changed to
    an WARN_ON, and the compatiablity code can be made configurable.

    Some function pointers aren't moved:
    * destructor can't be in net_device_ops because
      it may need to be referenced after the module is unloaded.
    * neighbor setup is manipulated in a couple of places that need special
      consideration
    * hard_start_xmit is in the fast path for transmit.

    cfg80211: introduce critical protocol indication from user-space

    Some protocols need a more reliable connection to complete
    successful in reasonable time. This patch adds a user-space
    API to indicate the wireless driver that a critical protocol
    is about to commence and when it is done, using nl80211 primitives
    NL80211_CMD_CRIT_PROTOCOL_START and NL80211_CRIT_PROTOCOL_STOP.

    There can be only on critical protocol session started per
    registered cfg80211 device.

    The driver can support this by implementing the cfg80211 callbacks
    .crit_proto_start() and .crit_proto_stop(). Examples of protocols
    that can benefit from this are DHCP, EAPOL, APIPA. Exactly how the
    link can/should be made more reliable is up to the driver. Things
    to consider are avoid scanning, no multi-channel operations, and
    alter coexistence schemes.

There's only a single user of vb2_mmap_pfn_range() and
at least on 3.2 having the function in compat-3.9.c is
problematic if CPTCFG_BACKPORT_BUILD_DMA_SHARED_BUFFER

backports: don't backport rfkill, only API

There's not much point in backporting rfkill, if the base kernel
doesn't have it then providing the it as /dev/rfkill_backport
won't be picked up by any apps, and if the base kernel has it
then it would cause odd behaviour as the base kernel's platform
drivers using the rfkill API would not talk to the backported
modules rfkill.

An unusable backported rfkill isn't much better than not having
it at all, so change the way we backport rfkill and don't carry
the code but simply provide the API as wrappers.

If the base kernel is 3.10 or higher (the current version) then
don't change anything at all.

If the base kernel is 2.6.33 or higher (with the new rfkill API)
then just wrap the API and disable rfkill registrations for any
types that the base kernel doesn't know about.

For all other kernels, provide only static inlines that behave
like the rfkill API when rfkill isn't compiled in.

The downside is that we need to copy the rfkill API. This is,
however, very very stable (it essentially hasn't changed since
2.6.33), so that's not a problem.

backports: backport new bluetooth hidp session-management

Commit b4f34d8d9 on next-20130419 added new bluetooth hidp
session-management helper, then commit 520518 also on
next-20130419 replaced the old management code with
the new one. Thanks to David Herrmann for his review and
his changes for this backport.

commit b4f34d8d9d26b2428fa7cf7c8f97690a297978e6
Author: David Herrmann <dh.herrmann@gmail.com>
Date:   Sat Apr 6 20:28:46 2013 +0200

    Bluetooth: hidp: add new session-management helpers

    This is a rewrite of the HIDP session management. It implements HIDP as an
    l2cap_user sub-module so we get proper notification when the underlying
    connection goes away.

    The helpers are not yet used but only added in this commit. The old
    session management is still used and will be removed in a following patch.

    The old session-management was flawed. Hotplugging is horribly broken and
    we have no way of getting notified when the underlying connection goes
    down. The whole idea of removing the HID/input sub-devices from within the
    session itself is broken and suffers from major dead-locks. We never can
    guarantee that the session can unregister itself as long as we use
    synchronous shutdowns. This can only work with asynchronous shutdowns.
    However, in this case we _must_ be able to unregister the session from the
    outside as otherwise the l2cap_conn object might be unlinked before we
    are.

    The new session-management is based on l2cap_user. There is only one
    way how to add a session and how to delete a session: "probe" and "remove"
    callbacks from l2cap_user.
    This guarantees that the session can be registered and unregistered at
    _any_ time without any synchronous shutdown.
    On the other hand, much work has been put into proper session-refcounting.
    We can unregister/unlink the session only if we can guarantee that it will
    stay alive. But for asynchronous shutdowns we never know when the last
    user goes away so we must use proper ref-counting.

    The old ->conn field has been renamed to ->hconn so we can reuse ->conn in
    the new session management. No other existing HIDP code is modified.

This provides a requirement of the new qxl DRM driver to
be available only on kernels >= 3.3. The requirement
comes from the usage of radix_tree_for_each_slot() that
this uses the new radix bit-optimized iterator added
via 78c1d7848 on 3.4. We backport this via the compat
module but only for v3.3 given that addressing this
backport for v3.2 requires addressing e2bdb933 which
changes the radix_tree_node.

qxl was added on next-20130415.

Someone wishing to #ifdef this to enable qxl support on

    drm: add new QXL driver. (v1.4)

    QXL is a paravirtual graphics device used by the Spice virtual desktop
    interface.

    The drivers uses GEM and TTM to manage memory, the qxl hw fencing however
    is quite different than normal TTM expects, we have to keep track of a number
    of non-linear fence ids per bo that we need to have released by the hardware.

    The releases are freed from a workqueue that wakes up and processes the
    release ring.

    releases are suballocated from a BO, there are 3 release categories, drawables,
    surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling.

    The hardware also have a surface id tracking mechnaism and the driver
    encapsulates it completely inside the kernel, userspace never sees the actual hw sur
    ids.

    This requires a newer version of the QXL userspace driver, so shouldn't be
    enabled until that has been placed into your distro of choice.

    Authors: Dave Airlie, Alon Levy

    v1.1: fixup some issues in the ioctl interface with padding
    v1.2: add module device table
    v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq,

    brcmfmac: define and use platform specific data for SDIO.

    This patch adds support for platform specific data for SDIO

compat: backport radix-tree bit optimized iterator

This backport's Konstantin's radix-tree bit optimized
iterator, 78c1d7848, added on v3.4. This is used by a new
drivers in the future. The new bit optimized iterator relies
on the stack optimization introduced via e2bdb933 added as of
v3.3. Backporting the bit optimized iterator requires
adjusting it to the old v3.2 radix_tree_node which is not
implemented here. For kernels v3.3 - v3.3 we can backport
the bit optimized iterator given that the radix_tree_node
did not changed between v3.3 - v3.4, in fact it hasn't
changed even up to v3.10. The backport relies on the same
helpers and inlines present on v3.3-v3.10 to implement
radix_tree_next_chunk().

This was tested as of next-20130410.

Throw the helper into compat config build option
CPTCFG_BACKPORT_BUILD_RADIX_HELPERS only to be built
on v3.3 right now unless someone really wants to
backport 78c1d7848 support onto v3.2.

    radix-tree: introduce bit-optimized iterator

    A series of radix tree cleanups, and usage of them in the core pagecache
    code.

    Micro-benchmark:

    lookup 14 slots (typical page-vector size)
    in radix-tree there earch <step> slot filled and tagged
    before/after - nsec per full scan through tree

    * Intel Sandy Bridge i7-2620M 4Mb L3
    New code always faster

    * AMD Athlon 6000+ 2x1Mb L2, without L3
    New code generally faster,
    Minor degradation (marked with "*") for huge sparse trees

    * i386 on Sandy Bridge
    New code faster for common cases: tagged and dense trees.
    Some degradations for non-tagged lookup on sparse trees.

    Ideally, there might help __ffs() analog for searching first non-zero

    radix_tree: take radix_tree_path off stack

    Down, down in the deepest depths of GFP_NOIO page reclaim, we have
    shrink_page_list() calling __remove_mapping() calling __delete_from_
    swap_cache() or __delete_from_page_cache().

    You would not expect those to need much stack, but in fact they call
    radix_tree_delete(): which declares a 192-byte radix_tree_path array on
    its stack (to record the node,offsets it visits when descending, in case
    it needs to ascend to update them).  And if any tag is still set [1],
    that calls radix_tree_tag_clear(), which declares a further such
    192-byte radix_tree_path array on the stack.  (At least we have
    interrupts disabled here, so won't then be pushing registers too.)

    That was probably a good choice when most users were 32-bit (array of
    half the size), and adding fields to radix_tree_node would have bloated
    it unnecessarily.  But nowadays many are 64-bit, and each
    radix_tree_node contains a struct rcu_head, which is only used when
    freeing; whereas the radix_tree_path info is only used for updating the
    tree (deleting, clearing tags or setting tags if tagged) when a lock
    must be held, of no interest when accessing the tree locklessly.

    So add a parent pointer to the radix_tree_node, in union with the
    rcu_head, and remove all uses of the radix_tree_path.  There would be
    space in that union to save the offset when descending as before (we can
    argue that a lock must already be held to exclude other users), but
    recalculating it when ascending is both easy (a constant shift and a
    constant mask) and uncommon, so it seems better just to do that.

    Two little optimizations: no need to decrement height when descending,
    adjusting shift is enough; and once radix_tree_tag_if_tagged() has set
    tag on a node and its ancestors, it need not ascend from that node
    again.

    perf on the radix tree test harness reports radix_tree_insert() as 2%
    slower (now having to set parent), but radix_tree_delete() 24% faster.
    Surely that's an exaggeration from rtth's artificially low map shift 3,
    but forcing it back to 6 still rates radix_tree_delete() 8% faster.

backports: backport dma-buf debugfs support

Commit 5a753a4 on next-20130410 extended the
dma-buf implementation to add debugfs support.
We backport support for this by adding its own
subsys_init() call as a helper to the backport
module (still called compat) respective subsys_init()
call, backport_init(). For kernels where this is
already supported this is a no-op.

This didn't make it to v3.9 but I see Linus has
already merged this as part of the merge window
what will be v3.10.

This also refreshes patches for next-20130410 and
I supply the refresh as part of this same patch
given that the only patch refreshed was the one
modifyin the drivers/base/dma-buf.c.

compat: backport soc_camera_power_[on|off] for 3.3

We are only backporting CONFIG_SOC_CAMERA for kernels >= 3.4
but there is an exported symbol from there that some media
drivers that we do support on 3.3 need. Handle this special
case.

SOC_CAMERA is only enabled on 3.4 as it depends on some
newer regulator functionality, however there are some SOC
cameras that can rely on the 3.3 regulatory built-in core
and the 3.3 SOC_CAMERA module however two routines are
not exported in that version of SOC_CAMERA that newer
SOC cameras do require. Backport that functionality.

Technically this should go into <media/soc_camera.h>
given that is where its where its exported on linux-next
but in practice only placing it on <linux/v4l2-mediabus.h>
actually fixes linking errors for 3.3 for all SOC camera
drivers we make available for 3.3:

be available to older kernels as of 3.6 but it was only
up to 3.8 where it was detangled from depending on

we may need to backport later with the same circumstances.

One last hack was required for 3.3-3.6 and that is due
to header changes between kernels.

which causes issues as that pulls in some required

backports: include hardirq into netdevice.h

On newer kernels this is included (indirectly) and

backports: avoid vfree() const warning

On newer kernels const pointers can be passed to vfree()
and vunmap(), doing so on old kernels causes warnings
that we can suppress with a cast.
