 - Partial (non PAGE_SIZE) write with incompressible data: In this
case, reference was made to a kfree()'ed buffer.

udldrmfb only reads the main EDID block, and if that advertises extensions
the drm_edid code expects them to be present, and starts reading beyond the
buffer udldrmfb passes it.

Although it may be possible to read more EDID info with the udl we simpy don't
know how, and even if trial and error gets it working on one device, that is
no guarantee it will work on other revisions. So this patch does a simple fix
in the form of patching the EDID info to report 0 extension blocks, this
fixes udldrmfb only doing 1024x768 on monitors with EDID extension blocks.

Fixes regression introduced in commit 861d2107
"drm/nouveau/fb: merge fb/vram and port to subdev interfaces"

nv50_fb_vram_{new,del} functions were changed to use
nouveau_subdev->mutex instead of the old nouveau_mm->mutex.
nvc0_fb_vram_new still uses the nouveau_mm->mutex, but nvc0 doesn't
have its own fb_vram_del function, using nv50_fb_vram_del instead.
Because of this, on nvc0 a different mutex ends up being used to protect
additions and deletions to the same list.

"drm/nouveau/clock: pull in the implementation from all over the place"

When code was moved from nv50_crtc_set_clock to nvc0_clock_pll_set,
the PLLs it is used for got limited to only the first two VPLLs.

nv50_crtc_set_clock was only called to change VPLLs, so it didn't
limit what it was used for in any way. Since nvc0_clock_pll_set is
used for all PLLs, it has to specify which PLLs the code is used for,
and only listed the first two VPLLs.

Since commit 5e120f6e "drm/nouveau/fence:
convert to exec engine, and improve channel sync" nouveau fence sync
implementation for nv17-50 and nvc0+ started to rely on state of fence buffer
left by previous sync operation. But as pinned bo's (where fence state is
stored) are not saved+restored across suspend/resume, we need to do it
manually.

nvc0+ was fixed by commit d6ba6d21
"drm/nvc0/fence: restore pre-suspend fence buffer context on resume".

Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate
from create/destroy") started to call display init routines on pre-nv50
hardware on module load. But LVDS init code sets driver state in a way
which prevents modesetting code from operating properly.

nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to
NV_DPMS_CLEARED.

drm_crtc_helper_set_mode
  nv04_dfp_prepare
    nv04_lvds_dpms(DRM_MODE_DPMS_OFF)

nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly
assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too,
so it skips calling some crucial lvds scripts.

This fix was put in place to fix a bug where the eDP panel on certain
laptops fails to respond over the aux channel after suspend.

It appears that on some systems (Dell M6600, with LVDS panel) there's a
very bad interaction with the eDP init table that causes the SOR to get
very confused and not drive the panel correctly, leading to bleed.

A DPMS off/on cycle is enough to bring it back, but, this will avoid the
problem by not touching the panel GPIOs at times we're not meant to.

commit e49cc34f introduced an unconditional IRQ_HANDLED return in be_intx()
to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel
from detecting interrupt storms due to broken HW.

The BE2/Lancer HW issues are:
1) In Lancer, there is no means for the driver to detect if the interrupt
belonged to device, other than counting and notifying events.
2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler
to be called multiple times till the de-assert happens.
3) In BE2, we see an occasional interrupt even when EQs are unarmed.

Issue (1) can cause the notified events to be orphaned, if NAPI was already
running.
This patch fixes this issue by scheduling NAPI only if it is not scheduled
already. Doing this also takes care of possible events_get() race that may be
caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first
time zero events are detected.

Michael points out that even after Stefan's fix the TUNSETIFF is still allowed
to create a new tap device. This because we only check tfile->tun but the
tfile->detached were introduced. Fix this by failing early in tun_set_iff() if
the file is detached. After this fix, there's no need to do the check again in
tun_set_iff(), so this patch removes it.

Setting SDIS (Stream Disable Mode- bit 4 of USBMODE register) fixes the problem.

However, in current code CI13XXX_DISABLE_STREAMING flag is only set in udc mode,
so allow disabling streaming also in host mode.

Tested on a mx6qsabrelite board.

Commit 09f6ffde (USB: EHCI: fix build error by making ChipIdea host a
normal EHCI driver) introduced a dependency on USB_EHCI_HCD for the
chipidea USB host driver, that in turns depends on USB_ARCH_HAS_EHCI.

If this symbol is not set for MXS, the MXS boards are not able to use
the chipidea driver anymore.

    net: provide a default dev->ethtool_ops

wireless core does not correctly assign ethtool_ops.

After alloc_netdev*() call, some cfg80211 drivers provide they own
ethtool_ops, but some do not. For them, wireless core provide generic
cfg80211_ethtool_ops, which is assigned in NETDEV_REGISTER notify call:

        if (!dev->ethtool_ops)
                dev->ethtool_ops = &cfg80211_ethtool_ops;

But after Eric's commit, dev->ethtool_ops is no longer NULL (on cfg80211
drivers without custom ethtool_ops), but points to &default_ethtool_ops.

In order to fix the problem, provide function which will overwrite
default_ethtool_ops and use it by wireless core.

It is werid that qlge driver supports NETIF_F_TSO6 but
not NETIF_F_IPV6_CSUM. This also causes some kernel warning [1]
when VLAN device setups on a qlge interface.

I think the qlge hardware doesn't support NETIF_F_IPV6_CSUM,
so we have to just remove the NETIF_F_TSO6 flag.

After this patch, the TCP/IPv6 traffic becomes normal again,
no kernel warnings any more.

NOTE: I only tested it on 2.6.32 kernel, even if the upstream
kernel could fix this automatically (it is hard to track NETIF*
flags), removing it is also safe.
