nouveau_bo_init() is backed by ttm_bo_init() and ferries its return code
back to the caller. On failures, ttm_bo_init() invokes the provided
destructor which should de-initialize and free the memory.
Thus, when nouveau_bo_init() returns an error the gem object has already
been released and the memory freed by nouveau_bo_del_ttm().

The gbefb driver not only registers a driver but also the device for that
driver. This is all well and good when run on the IP32 machines that are
supported by the driver but since the driver supports building with
COMPILE_TEST we might also be building on other platforms which do not have
this hardware and will crash instantiating the driver. Add an IS_ENABLED()
check so we compile out the device registration if we don't have the Kconfig
option for the machine enabled.

Configurations with both CONFIG_FB_SIMPLE=y and CONFIG_DRM_SIMPLEDRM=m
are allowed by Kconfig because the 'depends on !DRM_SIMPLEDRM' dependency
does not disallow FB_SIMPLE as long as SIMPLEDRM is not built-in. This
can however result in a build failure when cfb_fillrect() etc are then
also in loadable modules:
x86_64-linux-ld: drivers/video/fbdev/simplefb.o:(.rodata+0x1f8): undefined reference to `cfb_fillrect'
x86_64-linux-ld: drivers/video/fbdev/simplefb.o:(.rodata+0x200): undefined reference to `cfb_copyarea'
x86_64-linux-ld: drivers/video/fbdev/simplefb.o:(.rodata+0x208): undefined reference to `cfb_imageblit'
To work around this, change FB_SIMPLE to be a 'tristate' symbol,
which still allows both to be =m together, but not one of them to
be =y if the other one is =m. If a distro kernel picks this
configuration, it can be determined by local policy which of
the two modules gets loaded. The 'of_chosen' export is needed
as this is the first loadable module referencing it.
Alternatively, the Kconfig dependency could be changed to
'depends on DRM_SIMPLEDRM=n', which would forbid the configuration
with both drivers.

After commit 928f9e268611 ("clk: fractional-divider: Hide
clk_fractional_divider_ops from wide audience") was merged it appears
that the DSI panel on my Odroid Go Advance stopped working. Upon closer
examination of the problem, it looks like it was the fixup in the
rockchip_drm_vop.c file was causing the issue. The changes made to the
clk driver appear to change some assumptions made in the fixup.
After debugging the working 5.14 kernel and the no-longer working
5.15 kernel, it looks like this was broken all along but still
worked, whereas after the fractional clock change it stopped
working despite the issue (it went from sort-of broken to very broken).
In the 5.14 kernel the dclk_vopb_frac was being requested to be set to
17000999 on my board. The clock driver was taking the value of the
parent clock and attempting to divide the requested value from it
(17000000/17000999 = 0), then subtracting 1 from it (making it -1),
and running it through fls_long to get 64. It would then subtract
the value of fd->mwidth from it to get 48, and then bit shift
17000999 to the left by 48, coming up with a very large number of
7649082492112076800. This resulted in a numerator of 65535 and a
denominator of 1 from the clk driver. The driver seemingly would
try again and get a correct 1:1 value later, and then move on.
Output from my 5.14 kernel (with some printfs for good measure):
[ 2.830066] rockchip-drm display-subsystem: bound ff460000.vop (ops vop_component_ops)
[ 2.839431] rockchip-drm display-subsystem: bound ff450000.dsi (ops dw_mipi_dsi_rockchip_ops)

Contrast this with 5.15 after the clk change where the rate of 17000999
was getting passed and resulted in numerators/denomiators of 17001/
17000.
Output from my 5.15 kernel (with some printfs added for good measure):

[ 2.891281] Rate 17001000, Parent Rate 17000000, Best Numerator 17001, Best Denominator 17000
I have tested the change extensively on my Odroid Go Advance (Rockchip
RK3326) and it appears to work well. However, this change will affect
all Rockchip SoCs that use this driver so I believe further testing
is warranted. Please note that without this change I can confirm
at least all PX30s with DSI panels will stop working with the 5.15
kernel.
Upon advice from Doug Anderson <dianders@chromium.org> it was decided
that we would first check if the clock rate can be set exactly as
requested, and only if it could not would we then add 999 to it and
attempt the process again. This way we can preserve the behavior for
clocks that still need it while resolving the specific issue for the
PX30 and DSI panels (since it is using a fractional clock).
Changes since v2:
- Moved fixes to correct location.
Changes since v1:
- Made the addition of 999 conditional based on whether the clock
subsystem can set the actual clock rate as requested.
- Updated the notes in the fixup routine to reflect this new behavior.
- Added reference to original commit, as this has technically been
broken since then however only now is it an issue due to the clock
changes.

We don't currently have any kind of real acceleration on Ampere GPUs,
but the TTM memcpy() fallback paths aren't really designed to handle
copies between different devices, such as on Optimus systems, and
result in a kernel OOPS.
A few options were investigated to try and fix this, but didn't work
out, and likely would have resulted in a very unpleasant experience
for users anyway.
This commit adds just enough support for setting up a single channel
connected to a copy engine, which the kernel can use to accelerate
the buffer copies between devices. Userspace has no access to this
incomplete channel support, but it's suitable for TTM's needs.
A more complete implementation of host(fifo) for Ampere GPUs is in
the works, but the required changes are far too invasive that they
would be unsuitable to backport to fix this issue on current kernels.

Recent rework, which made HDMI PHY driver a platform device, inadvertely
reversed clock setup order. HW is very touchy about it. Proper way is to
handle controllers resets and clocks first and HDMI PHYs second.
Currently, without this fix, first mode set completely fails (nothing on
HDMI monitor) on H3 era PHYs. On H6, it still somehow work.
Move HDMI PHY reset & clocks handling to sun8i_hdmi_phy_init() which
will assure that code is executed after controllers reset & clocks are
handled. Additionally, add sun8i_hdmi_phy_deinit() which will deinit
them at controllers driver unload.
Tested on A64, H3, H6 and R40.

In current code, when a PCI error state pci_channel_io_normal is detectd,
it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI
driver will continue the execution of PCI resume callback report_resume by
pci_walk_bridge, and the callback will go into amdgpu_pci_resume
finally, where write lock is releasd unconditionally without acquiring
such lock first. In this case, a deadlock will happen when other threads
start to acquire the read lock.
To fix this, add a member in amdgpu_device strucutre to cache
pci_channel_state, and only continue the execution in amdgpu_pci_resume
when it's pci_channel_io_frozen.

This restricts the QCOM_SCM driver to depend on ARCH_QCOM, to reduce
it's presence after becoming a loadable module.
It then fixes a regression in the mdt_loader, where firmware with the
hash segment marked as PT_LOAD would no longer be accepted, preventing
several MSM8974 and SDM660 devices from loading remoteproc firmware.
Lastly it corrects the drvdata associated with the socinfo device during

According to Synopsys DesignWare Cores Ethernet PCS databook, it is
required to disable Clause 37 auto-negotiation by programming bit-12

A recent change that started reporting break events forgot to push the

A recent change that started reporting break events to the line
discipline caused the tty-buffer insertions to no longer be serialised
by inserting events also from the completion handler for the interrupt
endpoint.
Completion calls for distinct endpoints are not guaranteed to be
serialised. For example, in case a host-controller driver uses
bottom-half completion, the interrupt and bulk-in completion handlers
can end up running in parallel on two CPUs (high-and low-prio tasklets,
respectively) thereby breaking the tty layer's single producer
assumption.
Fix this by holding the read lock also when inserting characters from
the bulk endpoint.

Async feedback patches broke enumeration on Windows 10 previously fixed
by commit 789ea77310f0 ("usb: gadget: f_uac2: always increase endpoint
max_packet_size by one audio slot").
While the existing calculation for EP OUT capture for async mode yields
size+1 frame due to uac2_opts->fb_max > 0, playback side lost the +1
feature. Therefore the +1 frame addition must be re-introduced for
playback. Win10 enumerates the device only when both EP IN and EP OUT
max packet sizes are (at least) +1 frame.

When passing 'phys' in the devicetree to describe the USB PHY phandle

This happens because the charger functions check for the phy presence
inside the imx_usbmisc_data structure (data->usb_phy), but the chipidea
core populates the usb_phy passed via 'phys' inside 'struct ci_hdrc'

This causes the NULL pointer dereference inside imx7d_charger_detection().
Fix it by also searching for 'phys' in case 'fsl,usbphy' is not found.

USB TCPCI Spec, 4.4.3 Mask Registers:
"A masked register will still indicate in the ALERT register, but shall
not set the Alert# pin low."
Thus, the Extended Status will still indicate in ALERT register if vSafe0V
is detected by TCPC even though being masked. In current code, howerer,
this event will not be handled in detection time. Rather it will be
handled when next ALERT event coming(CC evnet, PD event, etc).
Tcpm might transition to a wrong state in this situation. Thus, the vSafe0V
event should not be handled when it's masked.

For the situation that the disconnect event comes very late when the
device is unplugged, the driver would resubmit the RX bulk transfer
after getting the callback with -EPROTO immediately and continually.
Finally, soft lockup occurs.
This patch avoids to resubmit RX immediately. It uses a workqueue to
schedule the RX NAPI. And the NAPI would resubmit the RX. It let the
disconnect event have opportunity to stop the submission before soft
lockup.

Decouple XEN_DOM0 from XEN_PV, converting some existing uses of XEN_DOM0
to a new XEN_PV_DOM0. (I'm not convinced all are really / should really
be PV-specific, but for starters I've tried to be conservative.)
For PVH Dom0 the hypervisor populates MADT with only x2APIC entries, so
without x2APIC support enabled in the kernel things aren't going to work
very well. (As opposed, DomU-s would only ever see LAPIC entries in MADT
as of now.) Note that this then requires PVH Dom0 to be 64-bit, as
X86_X2APIC depends on X86_64.
In the course of this xen_running_on_version_or_later() needs to be
available more broadly. Move it from a PV-specific to a generic file,
considering that what it does isn't really PV-specific at all anyway.
Note that xen/interface/version.h cannot be included on its own; in
enlighten.c, which uses SCHEDOP_* anyway, include xen/interface/sched.h
first to resolve the apparently sole missing type (xen_ulong_t).

The function doesn't use it and all of its callers say in a comment that
their respective arguments are to be non-NULL only in auto-translated
mode. Since xen_remap_domain_mfn_array() isn't supposed to be used by
non-PV, drop the parameter there as well. It was bogusly passed as non-
NULL (PRIV_VMA_LOCKED) by its only caller anyway. For
xen_remap_domain_gfn_range(), otoh, it's not clear at all why this
wouldn't want / might not need to gain auto-translated support down the
road, so the parameter is retained there despite now remaining unused
(and the only caller passing NULL); correct a respective comment as
well.
