ad4a362635 drm/nouveau/bios: split out shadow methods
We're about to need to be able to fetch additional chunks of data beyond
the primary bios image, which makes fetching a lot more complicated.

This splits out the verious shadowing routines to be nothing more than
very dumb "fetch this much data from this offset" routines, and leaves
the logic of what and how much to fetch in common code.

f9fc36618b soc/tegra: fuse: export tegra_sku_info
Some Tegra drivers might be compiled as kernel modules, and they need the
fuse information for initialization. One example is the GK20A Nouveau
driver. It needs the GPU speedo value to calculate frequency-voltage
table. So export the tegra_sku_info.

ed02bfa4aa SCSI fixes on 20141128

 a potential null deref in the voltage regulator code, a race on module unload,
 a ref counting fix on the well known LUNs which made it impossible to remove
 the ufs module and fix to correct the information in pwr_info.  In addition to
 UFS, there's a blacklist for the Intel Multi-Flex array which chokes on report
 supported operation codes and a fix to an oops in bnx2fc caused by shared

070e76cb3f MIPS: tlbex: Fix potential HTW race on TLBL/M/S handlers
There is a potential race when probing the TLB in TLBL/M/S exception
handlers for a matching entry. Between the time we hit a TLBL/S/M
exception and the time we get to execute the TLBP instruction, the
HTW may have replaced the TLB entry we are interested in hence the TLB
probe may fail. However, in the existing handlers, we never checked the
status of the TLBP (ie check the result in the C0/Index register). We
fix this by adding such a check when the core implements the HTW. If
we couldn't find a matching entry, we return back and try again.

3f4aa45cee ARM: 8226/1: cacheflush: get rid of restarting block
We cannot restart cacheflush safely if a process provides user-defined
signal handler and signal is pending. In this case -EINTR is returned
and it is expected that process re-invokes syscall. However, there are
a few problems with that:
 * looks like nobody bothers checking return value from cacheflush
 * but if it did, we don't provide the restart address for that, so the
   process has to use the same range again
 * ...and again, what might lead to looping forever

So, remove cacheflush restarting code and terminate cache flushing
as early as fatal signal is pending.

995ab5189d ARM: 8222/1: mvebu: enable strex backoff delay
Under extremely rare conditions, in an MPCore node consisting of at
least 3 CPUs, two CPUs trying to perform a STREX to data on the same
shared cache line can enter a livelock situation.

This patch enables the HW mechanism that overcomes the bug. This fixes
the incorrect setup of the STREX backoff delay bit due to a wrong
description in the specification.

Note that enabling the STREX backoff delay mechanism is done by
leaving the bit *cleared*, while the bit was currently being set by
the proc-v7.S code.

[Thomas: adapt to latest mainline, slightly reword the commit log, add
stable markers.]

e5b5341c28 drm/atomic: clear plane's CRTC and FB when shutting down
Otherwise we'd still end up w/ the plane attached to the CRTC, and
seemingly active, but without an FB.  Which ends up going *boom*
in the drivers.

Slightly modified version of Daniel's irc suggestion.

Note that the big problem isn't drivers going *boom* here (since we
already have the situation of planes being left enabled when the crtc
goes down). The real issue is that the core assumes the primary plane
always goes down when calling ->set_config with a NULL mode. Ignoring
that assumption leads to the legacy state pointers plane->fb/crtc
getting out of sync with atomic, and that then leads to the subsequent
*boom* all over the place.

abd69c55dd drm: Handle atomic state properly in kms getfoo ioctl
So the problem with async commit (especially async modeset commit) is
that the legacy pointers only get updated after the point of no
return, in the async part of the modeset sequence. At least as
implemented by the current helper functions. This is done in the
set_routing_links function in drm_atomic_helper.c.

Which also means that access isn't protected by locks but only
coordinated by synchronizing with async workers. No problem thus far,
until we lock at the getconnector/encoder ioctls.

So fix this up by adding special cases for atomic drivers: For those
we need to look at state objects. Unfortunately digging out the
correct encoder->crtc link is a bit of work, so wrap this up in a
helper function.

Moving the assignments of connector->encoder and encoder->crtc earlier
isn't a good idea because the point of the atomic helpers is that we
stage the state updates. That way the disable functions can still
inspect the links and rely upon them.

v2: Extract full encoder->crtc lookup into helper (Rob).

v3: Extract drm_connector_get_encoder too since - we need to always
return state->best_encoder when there is a state otherwise we might
return stale data if there's a pending async disable (and chase
unlocked pointers, too). Same issue with encoder_get_crtc but there
it's a bit more tricky to handle.

6ddd388ab2 drm/atomic: track bitmask of planes attached to crtc
Chasing plane->state->crtc of planes that are *not* part of the same
atomic update is racy, making it incredibly awkward (or impossible) to
do something simple like iterate over all planes and figure out which
ones are attached to a crtc.

Solve this by adding a bitmask of currently attached planes in the
crtc-state.

Note that the transitional helpers do not maintain the plane_mask.  But
they only support the legacy ioctls, which have sufficient brute-force
locking around plane updates that they can continue to loop over all
planes to see what is attached to a crtc the old way.

Signed-off-by: Rob Clark <robdclark@gmail.com>
[danvet:
- Drop comments about locking in set_crtc_for_plane since they're a
  bit misleading - we already should hold lock for the current crtc.
- Also WARN_ON if get_state on the old crtc fails since that should
  have been done already.
- Squash in fixup to check get_plane_state return value, reported by
  Dan Carpenter and acked by Rob Clark.]

9a343b9eb8 ARM: tegra: irq: fix buggy usage of irq_data irq field
The crazy gic_arch_extn thing that Tegra uses contains multiple
references to the irq field in struct irq_data, and uses this
to directly poke hardware register.

But irq is the *virtual* irq number, something that has nothing
to do with the actual HW irq (stored in the hwirq field). And once
we put the stacked domain code in action, the whole thing explodes,
as these two values are *very* different:

Just replacing all instances of irq with hwirq fixes the issue.

1348579433 drm/radeon: report disconnected for LVDS/eDP with PX if ddc fails
If ddc fails, presumably the i2c mux (and hopefully the signal
mux) are switched to the other GPU so don't fetch the edid from
the vbios so that the connector reports disconnected.

function. Fix it.

360d88a9e3 powerpc/powernv: Replace OPAL_DEASSERT_RESET with EEH_RESET_DEACTIVATE
The flag passed to ioda_eeh_phb_reset() should be EEH_RESET_DEACTIVATE,
which is translated to OPAL_DEASSERT_RESET or something else by the
EEH backend accordingly.

The patch replaces OPAL_DEASSERT_RESET with EEH_RESET_DEACTIVATE for
ioda_eeh_phb_reset().

21769c6754 Merge branch 'drm/du/adv7511' of git://linuxtv.org/pinchartl/fbdev into drm-next
The branch is based on a merge of drm-next and Simon's tags/renesas-dt-du-for-
v3.19 available at
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git, the latter
having been pulled in the ARM SoC tree for v3.19.

Compared to v1, I've rebased my branch on a later drm-next, added Julia's
error return code fix, and documented the "drm: Decouple EDID parsing from I2C
adapter" patch properly.

v1:
Here's a pull request that adds HDMI support to the R-Car DU driver, including
a new slave encoder driver for the adv7511.

was introduced by commit 2013add4ce. The patch fixes it up.
