mtd-ram can potentially be larger than 4GB. get_bitmask_order() uses
fls() that is not guaranteed to work with values larger than 32-bit.
Specifically on aarch64 fls() returns 0 when all 32 LSB bits are clear.
Use fls64() instead.
When the driver sets up the zpos property it sets the default zpos value
to the HW id of the plane. That is fine as such, but as on many DSS
versions the driver arranges the DRM planes in a different order than
the HW planes (to keep the non-scalable planes first), this leads to odd
initial zpos values. An example is J721e, where the initial zpos values
for DRM planes are 1, 3, 0, 2.
In theory the userspace should configure the zpos values properly when
using multiple planes, and in that sense the initial zpos values
shouldn't matter, but there's really no reason not to fix this and help
the userspace apps which don't handle zpos perfectly. In particular,
some versions of Weston seem to have issues dealing with the planes
with the current default zpos values.
So let's change the zpos values for the DRM planes to 0, 1, 2, 3.
Another option would be to configure the planes marked as primary planes
to zpos 0. On a two display system this would give us plane zpos values
of 0, 0, 1, 2. The end result and behavior would be very similar in this
option, and I'm not aware that this would actually help us in any way.
So, to keep the code simple, I opted for the 0, 1, 2, 3 values.

Per PCIe r6.1, sec 2.2.6.2 and 7.5.3.4, a Requester may not use 8-bit Tags
unless its Extended Tag Field Enable is set, but all Receivers/Completers
must handle 8-bit Tags correctly regardless of their Extended Tag Field
Enable.
Some devices do not handle 8-bit Tags as Completers, so add a quirk for
them. If we find such a device, we disable Extended Tags for the entire
hierarchy to make peer-to-peer DMA possible.
The 3ware 9650SE seems to have issues with handling 8-bit tags. Mark it as
broken.
The register bits definitions for RGB666 formats are wrong in multiple
ways: first, in the DSI_PS_SEL bits region, the Packed 18-bits RGB666
format is selected with bit 1, while the Loosely Packed one is bit 2,
and second - the definition name "LOOSELY_PS_18BIT_RGB666" is wrong
because the loosely packed format is 24 bits instead!
Either way, functions mtk_dsi_ps_control_vact() and mtk_dsi_ps_control()
do not even agree on the DSI_PS_SEL bit to set in DSI_PSCTRL: one sets
loosely packed (24) on RGB666, the other sets packed (18), and the other
way around for RGB666_PACKED.
Fixing this entire stack of issues is done in one go:
- Use the correct bit for the Loosely Packed RGB666 definition
- Rename LOOSELY_PS_18BIT_RGB666 to LOOSELY_PS_24BIT_RGB666
- Change ps_bpp_mode in mtk_dsi_ps_control_vact() to set:
- Loosely Packed, 24-bits for MIPI_DSI_FMT_RGB666
- Packed, 18-bits for MIPI_DSI_FMT_RGB666_PACKED
Currently coefficients are applied only once, since they don't change.
However, this is done before enable bit is set and thus it doesn't get
applied properly.
Fix that by applying coefficients after enable bit is set. While this
means that it will be done evey time, it doesn't bring much time
penalty.

As Honza said, remove_inode_dquot_ref() currently does not release the
last dquot reference but instead adds the dquot to tofree_head list. This
is because dqput() can sleep while dropping of the last dquot reference
(writing back the dquot and calling ->release_dquot()) and that must not
happen under dq_list_lock. Now that dqput() queues the final dquot cleanup
into a workqueue, remove_inode_dquot_ref() can call dqput() unconditionally
and we can significantly simplify it.
Here we open code the simplified code of remove_inode_dquot_ref() into
remove_dquot_ref() and remove the function put_dquot_list() which is no
longer used.

When calling dvb_unregister_device, dmxdev->dvbdev (i.e. *pdvbdev in

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Use an anonymous union with a couple of anonymous structs in order to
keep userspace unchanged and refactor the related code accordingly:
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().
Revert the use of structr_size() and stay with IP_MSFILTER_SIZE() for
now, as in this case, the size of struct ip_msfilter didn't change with
the addition of the flexible array imsf_slist_flex[]. So, if we use
struct_size() we will be allocating and calculating the size of
struct ip_msfilter with one too many items for imsf_slist_flex[].

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Use an anonymous union with a couple of anonymous structs in order to
keep userspace unchanged:
Also, refactor the code accordingly and make use of the struct_size()
and flex_array_size() helpers.
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().
The 'len' variable can't be negative when assigned the result of
'min_t' because all 'min_t' parameters are cast to unsigned int,
and then the minimum one is chosen.
To fix the logic, check 'len' as read from 'optlen',
where the types of relevant variables are (signed) int.

The stackmap code relies on roundup_pow_of_two() to compute the number
of hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code.
The commit in the fixes tag actually attempted to fix this, but the fix
did not account for the UB, so the fix only works on CPUs where an
overflow does result in a neat truncation to zero, which is not
guaranteed. Checking the value before rounding does not have this

The devmap code allocates a number hash buckets equal to the next power
of two of the max_entries value provided when creating the map. When
rounding up to the next power of two, the 32-bit variable storing the
number of buckets can overflow, and the code checks for overflow by
checking if the truncated 32-bit value is equal to 0. However, on 32-bit
arches the rounding up itself can overflow mid-way through, because it
ends up doing a left-shift of 32 bits on an unsigned long value. If the
size of an unsigned long is four bytes, this is undefined behaviour, so
there is no guarantee that we'll end up with a nice and tidy 0-value at
the end.
Syzbot managed to turn this into a crash on arm32 by creating a
DEVMAP_HASH with max_entries > 0x80000000 and then trying to update it.
Fix this by moving the overflow check to before the rounding up
operation.

The "pending connections" feature was originally introduced with commit 4c67bc74f016 ("[Bluetooth] Support concurrent connect requests") and 6bd57416127e ("[Bluetooth] Handling pending connect attempts after
inquiry") to handle controllers supporting only a single connection request
at a time. Later things were extended to also cancel ongoing inquiries on
connect() with commit 89e65975fea5 ("Bluetooth: Cancel Inquiry before
Create Connection").
With commit a9de9248064b ("[Bluetooth] Switch from OGF+OCF to using only
opcodes"), hci_conn_check_pending() was introduced as a helper to
consolidate a few places where we check for pending connections (indicated
by the BT_CONNECT2 flag) and then try to connect.
This refactoring commit also snuck in two more calls to
hci_conn_check_pending():
- One is in the failure callback of hci_cs_inquiry(), this one probably
makes sense: If we send an "HCI Inquiry" command and then immediately
after a "Create Connection" command, the "Create Connection" command might
fail before the "HCI Inquiry" command, and then we want to retry the
"Create Connection" on failure of the "HCI Inquiry".
- The other added call to hci_conn_check_pending() is in the event handler
for the "Remote Name" event, this seems unrelated and is possibly a
copy-paste error, so remove that one.

Fix "double" clearing of interrupts, which can cause external events

The E1000_TSIRC Time Sync Interrupt Cause register can be cleared in two
ways, by either reading it or by writing '1' into the specific cause
bit. This is documented in section 8.16.1.
The following flow was used:
1. read E1000_TSIRC into 'tsicr';
2. handle the interrupts present into 'tsirc' and mark them in 'ack';
3. write 'ack' into E1000_TSICR;
As both (1) and (3) will clear the interrupt cause, if the same
interrupt happens again between (1) and (3) it will be ignored,
causing events to be missed.
Remove the extra clear in (3).

For those endpoint devices connect to system via hotplug capable ports,
users could request a hot reset to the device by flapping device's link
through setting the slot's link control register, as pciehp_ist() DLLSC
interrupt sequence response, pciehp will unload the device driver and
then power it off. thus cause an IOMMU device-TLB invalidation (Intel
VT-d spec, or ATS Invalidation in PCIe spec r6.1) request for non-existence
target device to be sent and deadly loop to retry that request after ITE
fault triggered in interrupt context.
That would cause following continuous hard lockup warning and system hang
Such issue could be triggered by all kinds of regular surprise removal
hotplug operation. like:
1. pull EP(endpoint device) out directly.
2. turn off EP's power.
3. bring the link down.
etc.
this patch aims to work for regular safe removal and surprise removal
unplug. these hot unplug handling process could be optimized for fix the
ATS Invalidation hang issue by calling pci_dev_is_disconnected() in
function devtlb_invalidation_with_pasid() to check target device state to
avoid sending meaningless ATS Invalidation request to iommu when device is
gone. (see IMPLEMENTATION NOTE in PCIe spec r6.1 section 10.3.1)
For safe removal, device wouldn't be removed until the whole software
handling process is done, it wouldn't trigger the hard lock up issue
caused by too long ATS Invalidation timeout wait. In safe removal path,
device state isn't set to pci_channel_io_perm_failure in
pciehp_unconfigure_device() by checking 'presence' parameter, calling
pci_dev_is_disconnected() in devtlb_invalidation_with_pasid() will return
false there, wouldn't break the function.
For surprise removal, device state is set to pci_channel_io_perm_failure in
pciehp_unconfigure_device(), means device is already gone (disconnected)
call pci_dev_is_disconnected() in devtlb_invalidation_with_pasid() will
return true to break the function not to send ATS Invalidation request to
the disconnected device blindly, thus avoid to trigger further ITE fault,
and ITE fault will block all invalidation request to be handled.
furthermore retry the timeout request could trigger hard lockup.
Make pci_dev_is_disconnected() public so that it can be called from
Intel VT-d driver to quickly fix/workaround the surprise removal
unplug hang issue for those ATS capable devices on PCIe switch downstream
hotplug capable ports.
Beside pci_device_is_present() function, this one has no config space
space access, so is light enough to optimize the normal pure surprise
removal and safe removal flow.

When building with CONFIG_XEN_PV=y, .text symbols are emitted into
the .notes section so that Xen can find the "startup_xen" entry point.
This information is used prior to booting the kernel, so relocations
are not useful. In fact, performing relocations against the .notes
section means that the KASLR base is exposed since /sys/kernel/notes
is world-readable.
To avoid leaking the KASLR base without breaking unprivileged tools that
are expecting to read /sys/kernel/notes, skip performing relocations in
the .notes section. The values readable in .notes are then identical to
those found in System.map.
It is generally invalid to fail a Device Check notification if the scan
handler has not been attached to the given device after a bus rescan,
because there may be valid reasons for the scan handler to refuse
attaching to the device (for example, the device is not ready).

case without printing a warning.
While at it, reduce the log level of the "already enumerated" message
in the same function, because it is only interesting when debugging

We identified that the PHYs actually do not work since commit 7da7b84fee58
("ARM: dts: imx6dl-yapp4: Move phy reset into switch node") as
a coincidence of several circumstances.
The reset signal is kept asserted by a pull-down resistor on the board
unless it is deasserted by GPIO from the SoC. This is to keep the switch
dead until it is configured properly by the kernel and user space.
Prior to the referenced commit the switch was reset by the FEC driver
and the reset GPIO was actively deasserted. The mdio-bus was scanned
and the attached switch and its PHYs were found and configured.
With the referenced commit the switch is reset by the qca8k driver.
Because of another bug in the qca8k driver, functionality of the reset
pin depends on its pre-kernel configuration. See commit c44fc98f0a8f
("net: dsa: qca8k: fix illegal usage of GPIO")
The problem did not appear until we removed support for the switch
and configuration of its reset pin from the bootloader.
To fix that, properly describe the internal mdio-bus configuration of
the qca8334 switch. The PHYs are internal to the switch and sit on its
internal mdio-bus.
This change does not have any functional effect. The switch works just
fine without this patch as it has full access to all the addresses
on the bus. This is simply a clean-up to set the node name address
and reg address to the same value.

When the development chip ROM was added, the "direct-mapped" compatible

On many systems that have an AMD IOMMU the following sequence of
warnings is observed during bootup.
```
pci 0000:00:00.2 can't derive routing for PCI INT A
pci 0000:00:00.2: PCI INT A: not connected
```
This series of events happens because of the IOMMU initialization
sequence order and the lack of _PRT entries for the IOMMU.
During initialization the IOMMU driver first enables the PCI device
using pci_enable_device(). This will call acpi_pci_irq_enable()
which will check if the interrupt is declared in a PCI routing table
(_PRT) entry. According to the PCI spec [1] these routing entries
are only required under PCI root bridges:
The _PRT object is required under all PCI root bridges
The IOMMU is directly connected to the root complex, so there is no
parent bridge to look for a _PRT entry. The first warning is emitted
since no entry could be found in the hierarchy. The second warning is
then emitted because the interrupt hasn't yet been configured to any
value. The pin was configured in pci_read_irq() but the byte in
PCI_INTERRUPT_LINE return 0xff which means "Unknown".
After that sequence of events pci_enable_msi() is called and this
will allocate an interrupt.
That is both of these warnings are totally harmless because the IOMMU
uses MSI for interrupts. To avoid even trying to probe for a _PRT
entry mark the IOMMU as IRQ managed. This avoids both warnings.
