    reservation: cross-device reservation support, v4

    This adds support for a generic reservations framework that can be
    hooked up to ttm and dma-buf and allows easy sharing of reservations
    across devices.

    The idea is that a dma-buf and ttm object both will get a pointer
    to a struct reservation_object, which has to be reserved before
    anything is done with the contents of the dma-buf.

    Changes since v1:
     - Fix locking issue in ticket_reserve, which could cause
       mutex_unlock
       to be called too many times.
    Changes since v2:
     - All fence related calls and members have been taken out for now,
       what's left is the bare minimum to be useful for ttm locking conversion.
    Changes since v3:
     - Removed helper functions too. The documentation has an example
       implementation for locking. With the move to ww_mutex there is no
       need to have much logic any more.

backports: backport ww_mutex support

This backports the kernel's wound/wait style locks 040a0a371,
using the linux-stable v3.11-rc2 as a base for development.
Given the complexity to support debugging mutexes this backport
implementation is simplified by only making this feature availabe
if you to have DEBUG_MUTEXES and DEBUG_LOCK_ALLOC disabled.

Given that ww mutex is required for DRM this also means we must
update the kconfig for DRM and require you to also not be able to build
DRM if you have either of these options enabled. Support for
DEBUG_MUTEXES and DEBUG_LOCK_ALLOC can be added later by anyone
daring. This uses the new dependencies file kconfig language
extension to specify the backport feature build restrictions
for DRM.

Part of the ww mutex addition to the kernel required modifying
the fast path mutex locking scheme by requiring you to deal
with the slow path alternatives on your own (refer to a41b56ef).
The reason for this change was that the mutex fastpath implementation
assumed your slowpath alternative can only be passed one argument
and the addition of ww mutexes requires dealing with the slow
path with a context passed.

It'd be painful to backport all asm for an optimized fastpath
implementation so we penalize the backport ww mutex fast path
by using the generic atomic_dec_return().

To backport a clean our own mutex_lock_common() with the least
amount of changes against upstream commits 2bd2c92c and 41fcb9f2
also needed to be backported. Commit 2bd2c92c dealt with adding
support for queue mutex spinners with an MCS lock, since this
cannot be backported for older kernels we provide empty inlines.
Commit 41fcb9f2 just removed SCHED_FEAT_OWNER_SPIN as it was an
early hack, the only thing required to backport this commit was
to provide an alternative declaration for mutex_spin_on_owner()
as it was declared non-inline for older kernels.

Finally c5491ea7 required backporting schedule_preempt_disabled()
as well but that just consisted of carrying over the original
implementation. Since its not exported we need to reimplement
it to make it available to our internal core ww mutex port.

    mutex: Add support for wound/wait style locks

    Wound/wait mutexes are used when other multiple lock
    acquisitions of a similar type can be done in an arbitrary
    order. The deadlock handling used here is called wait/wound in
    the RDBMS literature: The older tasks waits until it can acquire
    the contended lock. The younger tasks needs to back off and drop
    all the locks it is currently holding, i.e. the younger task is
    wounded.

    For full documentation please read Documentation/ww-mutex-design.txt.

    arch: Make __mutex_fastpath_lock_retval return whether fastpath succeeded or not

    This will allow me to call functions that have multiple
    arguments if fastpath fails. This is required to support ticket
    mutexes, because they need to be able to pass an extra argument
    to the fail function.

    Originally I duplicated the functions, by adding
    __mutex_fastpath_lock_retval_arg. This ended up being just a
    duplication of the existing function, so a way to test if
    fastpath was called ended up being better.

    This also cleaned up the reservation mutex patch some by being
    able to call an atomic_set instead of atomic_xchg, and making it
    easier to detect if the wrong unlock function was previously
    used.

backports: enable kconfig language on dependencies file

Certain complex features that are backported may be be
limitted to a certain target build configuration. An example
can be if a backported feature is not yet backported with
support for lockdep. In order to avoid build failures with
these types of restrictions allow for specifying build
configuration dependencies on backported upstream kconfig
symbols other than just kernel versioning contstraints.

This adds support for specifying upstream kconfig constaints
other than kernel versioning by adding kconfig language
extensions on the dependencies file. This will update the
copied over upstream Kconfig file for the symbol specified
with the kconfig constraints specified.

backports: revert DMI_EXACT_MATCH() for older kernels

struct dmi_strmatch was modified on v3.11 with a
exact_match member. The DMI_EXACT_MATCH() macro was
added as a mod version of DMI_MATCH() to account for
dmi strings that look closely like each other. An
example is D510MO Vs D510MOV.

Since exact_match is is not available on older kernels
we can't use it and must revert to the old DMI_MATCH().
Addressing the desired behaviour will require a separate
change to deal with addressing the difference
in the behaviour.

Chris Wilson recommends that if we can't use this we should
also rever the DMI related fixes. I believe these are:

dcf6d294830d46b0e6901477fb4bf455281d90c8 - drm/i915: quirk away phantom LVDS on Intel's D525MW mainboard

Once we get confirmation we can do that.

Proof of why we can't backport DMI_EXACT_MATCH():

DMI_EXACT_MATCH uses struct dmi_strmatch's new
member exact_match:

@@ -456,7 +456,8 @@ enum dmi_field {
 };

 struct dmi_strmatch {
-       unsigned char slot;
+       unsigned char slot:7;
+       unsigned char exact_match:1;
char substr[79];
 };

Prior to 5017b285 we only had slot member so to use
DMI_EXACT_MATCH() with its intent we'd have to do something
like:
slot |= 1

if its called. This however assumes though that older code has
the sanity check as changed in 5017b285 on drivers/firmware/dmi_scan.c.
dmi_scan.o gets linked with CONFIG_DMI. At least for x86 that gets

    dmi: add support for exact DMI matches in addition to substring matching

    dmi_match() considers a substring match to be a successful match.  This is
    not always sufficient to distinguish between DMI data for different

    match for D510MO, without also incorrectly matching D510MOV:

                DMI_EXACT_MATCH(DMI_BOARD_NAME, "D510MO"),
