[ Upstream commit 50b3a818991074177a56c87124c7a7bdf5fa4f67 ]
We need to calculate the max file size accurately if the total blocks
that can address by block tree exceed the upper_limit. But this check is
not correct now, it only compute the total data blocks but missing
metadata blocks are needed. So in the case of "data blocks < upper_limit
&& total blocks > upper_limit", we will get wrong result. Fortunately,
this case could not happen in reality, but it's confused and better to
correct the computing.

This driver can use an interrupt or polling in order get the charger's
status.
When using polling, a delayed work is used.
However, the remove() function unconditionally call
cancel_delayed_work_sync(), even if the delayed work is not used and is not
initialized.
In order to fix it, use devm_delayed_work_autocancel() and remove the now
useless remove() function.

__setup() handlers should return 1 if the parameter is handled.
Returning 0 causes the entire string to be added to init's
environment strings (limited to 32 strings), unnecessarily polluting it.
Using the documented strings "TOMOYO_loader=string1" and
"TOMOYO_trigger=string2" causes an Unknown parameter message:
Unknown kernel command line parameters
"BOOT_IMAGE=/boot/bzImage-517rc5 TOMOYO_loader=string1 \
TOMOYO_trigger=string2", will be passed to user space.
and these strings are added to init's environment string space:
Run /sbin/init as init process
with arguments:
/sbin/init
with environment:
HOME=/
TERM=linux
BOOT_IMAGE=/boot/bzImage-517rc5
TOMOYO_loader=string1
TOMOYO_trigger=string2
With this change, these __setup handlers act as expected,
and init's environment is not polluted with these strings.

[ Upstream commit 1d6736c3e162061dc811c76e605f35ef3234bffa ]
NCQ NON DATA is an NCQ command with the DMA_NONE DMA direction and so a
register-device-to-host-FIS response is expected for it.
However, for an IO_SUCCESS case, mpi_sata_completion() expects a
set-device-bits-FIS for any ata task with an use_ncq field true, which
includes NCQ NON DATA commands.
Fix this to correctly treat NCQ NON DATA commands as non-data by also
testing for the DMA_NONE DMA direction.

tasks with a DMA direction of DMA_NONE (no data transfer) are initialized

DMA_NONE commands are NCQ commands and need to be initialized using the

the DMA direction. While at it, reorganize the code into a chain of if -

[ Upstream commit 26a17b12d7f3dd8a7aa45a290e5b46e9cc775ddf ]
If 'vfio_pci_core_device::needs_pm_restore' is set (PCI device does
not have No_Soft_Reset bit set in its PMCSR config register), then the
current PCI state will be saved locally in
'vfio_pci_core_device::pm_save' during D0->D3hot transition and same
will be restored back during D3hot->D0 transition. For reset-related
functionalities, vfio driver uses PCI reset API's. These
API's internally change the PCI power state back to D0 first if
the device power state is non-D0. This state change to D0 will happen
without the involvement of vfio driver.
Let's consider the following example:
1. The device is in D3hot.
2. User invokes VFIO_DEVICE_RESET ioctl.
3. pci_try_reset_function() will be called which internally
invokes pci_dev_save_and_disable().
4. pci_set_power_state(dev, PCI_D0) will be called first.
5. pci_save_state() will happen then.
Now, for the devices which has NoSoftRst-, the pci_set_power_state()
can trigger soft reset and the original PCI config state will be lost
at step (4) and this state cannot be restored again. This original PCI
state can include any setting which is performed by SBIOS or host
linux kernel (for example LTR, ASPM L1 substates, etc.). When this
soft reset will be triggered, then all these settings will be reset,
and the device state saved at step (5) will also have this setting
cleared so it cannot be restored. Since the vfio driver only exposes
limited PCI capabilities to its user, so the vfio driver user also
won't have the option to save and restore these capabilities state
either and these original settings will be permanently lost.
For pci_reset_bus() also, we can have the above situation.
The other functions/devices can be in D3hot and the reset will change
the power state of all devices to D0 without the involvement of vfio
driver.
So, before calling any reset-related API's, we need to make sure that
the device state is D0. This is mainly to preserve the state around
soft reset.
For vfio_pci_core_disable(), we use __pci_reset_function_locked()
which internally can use pci_pm_reset() for the function reset.
pci_pm_reset() requires the device power state to be in D0, otherwise
it returns error.
This patch changes the device power state to D0 by invoking
vfio_pci_set_power_state() explicitly before calling any reset related
API's.

not have No_Soft_Reset bit set in its PMCSR config register), then
the current PCI state will be saved locally in
'vfio_pci_core_device::pm_save' during D0->D3hot transition and same
will be restored back during D3hot->D0 transition.
For saving the PCI state locally, pci_store_saved_state() is being
used and the pci_load_and_free_saved_state() will free the allocated
memory.
But for reset related IOCTLs, vfio driver calls PCI reset-related
API's which will internally change the PCI power state back to D0. So,
when the guest resumes, then it will get the current state as D0 and it
will skip the call to vfio_pci_set_power_state() for changing the
power state to D0 explicitly. In this case, the memory pointed by
'pm_save' will never be freed. In a malicious sequence, the state changing
to D3hot followed by VFIO_DEVICE_RESET/VFIO_DEVICE_PCI_HOT_RESET can be
run in a loop and it can cause an OOM situation.
This patch frees the earlier allocated memory first before overwriting
'pm_save' to prevent the mentioned memory leak.

All DSI PHY/PLL drivers were referencing their VCO parent clock by a
global name, most of which don't exist or have been renamed. These
clock drivers seem to function fine without that except the 14nm driver
for sdm6xx [1].
At the same time all DTs provide a "ref" clock as per the requirements
of dsi-phy-common.yaml, but the clock is never used. This patchset puts
that clock to use without relying on a global clock name, so that all
dependencies are explicitly defined in DT (the firmware) in the end.
Note that this patch intentionally breaks older firmware (DT) that
relies on the clock to be found globally instead. The only affected
platform is msm8974 [2] for whose dsi_phy_28nm a .name="xo" fallback is
left in place to accommodate a more graceful transition period. All
other platforms had the "ref" clock added to their phy node since its
inception, or in a followup patch some time after. These patches
wrongly assumed that the "ref" clock was actively used and have hence
been listed as "Fixes:" below.
Furthermore apq8064 was providing the wrong 19.2MHz cxo instead of
27MHz pxo clock, which has been addressed in [3].
It is expected that both [2] and [3] are applied to the tree well in
advance of this patch such that any actual breakage is extremely
unlikely, but might still occur if kernel upgrades are performed without
the DT to match. After some time the fallback for msm8974 can be
removed again as well.

Each DP link training contains link training 1 followed by link
training 2. There is maximum of 5 retries of DP link training
before declared link training failed. It is required to stop link
training at end of link training 2 if it is failed so that next

DP CTS test case 4.2.2.6 has valid edid with bad checksum on purpose
and expect DP source return correct checksum. During drm edid read,
correct edid checksum is calculated and stored at
connector::real_edid_checksum.
The problem is struct dp_panel::connector never be assigned, instead the
connector is stored in struct msm_dp::connector. When we run compliance
testing test case 4.2.2.6 dp_panel_handle_sink_request() won't have a valid
edid set in struct dp_panel::edid so we'll try to use the connectors
real_edid_checksum and hit a NULL pointer dereference error because the
connector pointer is never assigned.

handling when calling bpf_btf_get_fd_by_id() changed. Before the rework
if bpf_btf_get_fd_by_id() failed the error would not be propagated to
callers of btf__get_from_id(), after the rework it is. This lead to a
change in behavior in print_key_value() that now prints an error when
trying to lookup keys in maps with no btf available.

When receiving netlink messages, libbpf was using a statically allocated
stack buffer of 4k bytes. This happened to work fine on systems with a 4k
page size, but on systems with larger page sizes it can lead to truncated
messages. The user-visible impact of this was that libbpf would insist no
XDP program was attached to some interfaces because that bit of the netlink
message got chopped off.
Fix this by switching to a dynamically allocated buffer; we borrow the
approach from iproute2 of using recvmsg() with MSG_PEEK|MSG_TRUNC to get
the actual size of the pending message before receiving it, adjusting the
buffer as necessary. While we're at it, also add retries on interrupted
system calls around the recvmsg() call.

When the dw-hdmi bridge is in first place of the bridge chain, this
means there is no way to select an input format of the dw-hdmi HW
component.
Since introduction of display-connector, negotiation was broken since
the dw-hdmi negotiation code only worked when the dw-hdmi bridge was
in last position of the bridge chain or behind another bridge also
supporting input & output format negotiation.
Commit 7cd70656d128 ("drm/bridge: display-connector: implement bus fmts callbacks")
was introduced to make negotiation work again by making display-connector
act as a pass-through concerning input & output format negotiation.
But in the case where the dw-hdmi is single in the bridge chain, for
example on Renesas SoCs, with the display-connector bridge the dw-hdmi
is no more single, breaking output format.

In CXL 2.0, 8.2.5.1 CXL Capability Header Register: this register
is given as 32 bits.
8.2.3 which covers the CXL 2.0 Component registers, including the
CXL Capability Header Register states that access restrictions
specified in Section 8.2.2 apply.
8.2.2 includes:
* A 32 bit register shall be accessed as a 4 Byte quantity.
...
If these rules are not followed, the behavior is undefined.
Discovered during review of CXL QEMU emulation. Alex Bennée pointed
out there was a comment saying that 4 byte registers must be read
with a 4 byte read, but 8 byte reads were being emulated.
https://lore.kernel.org/qemu-devel/87bkzyd3c7.fsf@linaro.org/
Fixing that, led to this code failing. Whilst a given hardware
implementation 'might' work with an 8 byte read, it should not be relied
upon. The QEMU emulation v5 will return 0 and log the wrong access width.
The code moved, so one fixes tag for where this will directly apply and
also a reference to the earlier introduction of the code for backports.
