When we run several VMs with PCI passthrough and GICv4 enabled, not
pinning vCPUs, we will occasionally see below warnings in dmesg:
ITS queue timeout (65440 65504 480)
ITS cmd its_build_vmovp_cmd failed
The reason for the above issue is that in BUILD_SINGLE_CMD_FUNC:
1. Post the write command.
2. Release the lock.
3. Start to read GITS_CREADR to get the reader pointer.
4. Compare the reader pointer to the target pointer.
5. If reader pointer does not reach the target, sleep 1us and continue
to try.
If we have several processors running the above concurrently, other
CPUs will post write commands while the 1st CPU is waiting the
completion. So we may have below issue:
phase 1:
---rd_idx-----from_idx-----to_idx--0---------
wait 1us:
phase 2:
--------------from_idx-----to_idx--0-rd_idx--
That is the rd_idx may fly ahead of to_idx, and if in case to_idx is
near the wrap point, rd_idx will wrap around. So the below condition
will not be met even after 1s:
if (from_idx < to_idx && rd_idx >= to_idx)
There is another theoretical issue. For a slow and busy ITS, the
initial rd_idx may fall behind from_idx a lot, just as below:
---rd_idx---0--from_idx-----to_idx-----------
This will cause the wait function exit too early.
Actually, it does not make much sense to use from_idx to judge if
to_idx is wrapped, but we need a initial rd_idx when lock is still
acquired, and it can be used to judge whether to_idx is wrapped and
the current rd_idx is wrapped.
We switch to a method of calculating the delta of two adjacent reads
and accumulating it to get the sum, so that we can get the real rd_idx
from the wrapped value even when the queue is almost full.

The MIPS GIC contains a block of registers used to map local interrupts
to a particular CPU interrupt pin. Since these registers are found at a
consecutive range of addresses we access them using an index, via the
(read|write)_gic_v[lo]_map accessor functions. We currently use values
from enum mips_gic_local_interrupt as those indices.
Unfortunately whilst enum mips_gic_local_interrupt provides the correct
offsets for bits in the pending & mask registers, the ordering of the
map registers is subtly different... Compared with the ordering of
pending & mask bits, the map registers move the FDC from the end of the
list to index 3 after the timer interrupt. As a result the performance
counter & software interrupts are therefore at indices 4-6 rather than
indices 3-5.
Notably this causes problems with performance counter interrupts being
incorrectly mapped on some systems, and presumably will also cause
problems for FDC interrupts.
Introduce a function to map from enum mips_gic_local_interrupt to the
index of the corresponding map register, and use it to ensure we access
the map registers for the correct interrupts.

irq_create_fwspec_mapping() can fail, returning 0 as parent_virq. In this
case vint_desc is going to be NULL in ti_sci_inta_alloc_irq() which will
cause NULL pointer dereference.
Also note that irq_create_fwspec_mapping() returns 'unsigned int' so the
check '<=' was wrong.
Use -EINVAL if irq_create_fwspec_mapping() returned with 0.

The csky,mpintc could deliver a external irq to one cpu or all cpus, but
it couldn't deliver a external irq to a group of cpus with cpu_mask. So
we only use auto deliver mode when affinity mask_val is equal to
cpu_present_mask.
There is no limitation for only two cpus in SMP system.

Replace the variable set function from "efivar_entry_set" to
"efivar_entry_set_safe" in efibc panic notifier.
In safe function parameter "block" will set to false
and will call "efivar_entry_set_nonblocking"to set efi variables.
efivar_entry_set_nonblocking is guaranteed to
not block and is suitable for calling from crash/panic handlers.
In UEFI android platform, when warm reset happens,
with this change, efibc will not block the reboot process.
Otherwise, set variable will call queue work and send to other offlined
cpus then cause another panic, finally will cause reboot failure.

Starting with ACPI 6.2 bits 1 and 2 of the BGRT status field are no longer
reserved. These bits are now used to indicate if the image needs to be
rotated before being displayed.
The first device using these bits has now shown up (the GPD MicroPC) and
the reserved bits check causes us to reject the valid BGRT table on this
device.
Rather then changing the reserved bits check, allowing only the 2 new bits,
instead just completely remove it so that we do not end up with a similar
problem when more bits are added in the future.

There are platforms that do not call pm_set_suspend_via_firmware(),
so pm_suspend_via_firmware() returns 'false' on them, but the power
states of PCI devices (PCIe ports in particular) are changed as a
result of powering down core platform components during system-wide
suspend. Thus the pm_suspend_via_firmware() checks in
pci_pm_suspend_noirq() and pci_pm_resume_noirq() introduced by
commit 3e26c5feed2a ("PCI: PM: Skip devices in D0 for suspend-to-
idle") are not sufficient to determine that devices left in D0
during suspend will remain in D0 during resume and so the bus-level
power management can be skipped for them.
For this reason, introduce a new global suspend flag,
PM_SUSPEND_FLAG_NO_PLATFORM, set it for suspend-to-idle only
and replace the pm_suspend_via_firmware() checks mentioned above
with checks against this flag.

Once we unlock adapter->hw_lock in pvscsi_queue_lck() nothing prevents just
queued scsi_cmnd from completing and freeing the request. Thus cmd->cmnd[0]
dereference can dereference already freed request leading to kernel crashes
or other issues (which one of our customers observed). Store cmd->cmnd[0]
in a local variable before unlocking adapter->hw_lock to fix the issue.

During suspend/resume, mtk_eint_mask may be called while
wake_mask is active. For example, this happens if a wake-source
with an active interrupt handler wakes the system:
irq/pm.c:irq_pm_check_wakeup would disable the interrupt, so
that it can be handled later on in the resume flow.
However, this may happen before mtk_eint_do_resume is called:
in this case, wake_mask is loaded, and cur_mask is restored
from an older copy, re-enabling the interrupt, and causing
an interrupt storm (especially for level interrupts).
Step by step, for a line that has both wake and interrupt enabled:
1. cur_mask[irq] = 1; wake_mask[irq] = 1; EINT_EN[irq] = 1 (interrupt
enabled at hardware level)
2. System suspends, resumes due to that line (at this stage EINT_EN
== wake_mask)
3. irq_pm_check_wakeup is called, and disables the interrupt =>
EINT_EN[irq] = 0, but we still have cur_mask[irq] = 1
4. mtk_eint_do_resume is called, and restores EINT_EN = cur_mask, so
it reenables EINT_EN[irq] = 1 => interrupt storm as the driver
is not yet ready to handle the interrupt.
This patch fixes the issue in step 3, by recording all mask/unmask
changes in cur_mask. This also avoids the need to read the current
mask in eint_do_suspend, and we can remove mtk_eint_chip_read_mask
function.
The interrupt will be re-enabled properly later on, sometimes after
mtk_eint_do_resume, when the driver is ready to handle it.

Before suspending, mtk-eint would set the interrupt mask to the
one in wake_mask. However, some of these interrupts may not have a
corresponding interrupt handler, or the interrupt may be disabled.
On resume, the eint irq handler would trigger nevertheless,
and irq/pm.c:irq_pm_check_wakeup would be called, which would
try to call irq_disable. However, if the interrupt is not enabled
(irqd_irq_disabled(&desc->irq_data) is true), the call does nothing,
and the interrupt is left enabled in the eint driver.
Especially for level-sensitive interrupts, this will lead to an
interrupt storm on resume.
If we detect that an interrupt is only in wake_mask, but not in
cur_mask, we can just mask it out immediately (as mtk_eint_resume
would do anyway at a later stage in the resume sequence, when
restoring cur_mask).

Currently probing of the mcp23s08 results in an error message
"detected irqchip that is shared with multiple gpiochips:
please fix the driver"
This is due to the following:
Call to mcp23s08_irqchip_setup() with call hierarchy:
mcp23s08_irqchip_setup()
gpiochip_irqchip_add_nested()
gpiochip_irqchip_add_key()
gpiochip_set_irq_hooks()
Call to devm_gpiochip_add_data() with call hierarchy:
devm_gpiochip_add_data()
gpiochip_add_data_with_key()
gpiochip_add_irqchip()
gpiochip_set_irq_hooks()
The gpiochip_add_irqchip() returns immediately if there isn't a irqchip
but we added a irqchip due to the previous mcp23s08_irqchip_setup()
call. So it calls gpiochip_set_irq_hooks() a second time.
Fix this by moving the call to devm_gpiochip_add_data before
the call to mcp23s08_irqchip_setup

value less than 0. This may be the case if a clk provider only specifies
the .name member to match a string in the "clock-names" DT property. We
shouldn't require that the index be >= 0 to make this use case work.

Currently the default clock rates for the HDA and HDA2CODEC_2X clocks
are both 19.2MHz. However, the default rates for these clocks should
actually be 51MHz and 48MHz, respectively. The current clock settings
results in a distorted output during audio playback. Correct the default
clock rates for these clocks by specifying them in the clock init table
for Tegra210.

If we do a clk_get() for a clock that does not exists, we have
_ti_omap4_clkctrl_xlate() return uninitialized data if no match
is found. This can be seen in some cases with SLAB_DEBUG enabled:
Unable to handle kernel paging request at virtual address 5a5a5a5a
...
clk_hw_create_clk.part.33
sysc_notifier_call
notifier_call_chain

Let's fix this by setting a found flag only when we find a match.

For the first call to realloc_argv() in dm_split_args(), old_argv is
NULL and size is zero. Then memcpy is called, with the NULL old_argv
as the source argument and a zero size argument. AFAIK, this is
undefined behavior and generates the following warning when compiled
with UBSAN on ppc64le:

Currently, although we submit super bios in order (and super.nr_entries
is incremented by each logged entry), submit_bio() is async so each
super sector may not be written to log device in order and then the
final nr_entries may be smaller than it should be.
This problem can be reproduced by the xfstests generic/455 with ext4:
QA output created by 455
-Silence is golden
+mark 'end' does not exist
Fix this by serializing submission of super sectors to make sure each
is written to the log disk in order.

Currently, in suspend() and resume(), ishtp client drivers are using
driver_data to get "struct ishtp_cl_device" object which is set by
bus driver. It's wrong since the driver_data should not be owned bus.
driver_data should be owned by the corresponding ishtp client driver.
Due to this, some ishtp client driver like cros_ec_ishtp which uses
its driver_data to transfer its data to its child doesn't work correctly.
So this patch removes setting driver_data in bus drier and instead of
using driver_data to get "struct ishtp_cl_device", since "struct device"
is embedded in "struct ishtp_cl_device", we introduce a helper function
that returns "struct ishtp_cl_device" from "struct device".

The HID++ spec also defines very long HID++ reports, with a reportid of
0x12. The MX5000 and MX5500 keyboards use 0x12 output reports for sending
messages to display on their buildin LCD.
Userspace (libmx5000) supports this, in order for this to work when talking
to the HID devices instantiated for the keyboard by hid-logitech-dj,
we need to properly forward these reports to the device.
This commit fixes logi_dj_ll_raw_request not forwarding these reports.

reset GPIO can be connected to e.g. I2C GPIO expander and it is perfectly
fine for the kernel to sleep for a bit in ksz_switch_register().

In configuration of vlan over bridge over aquantia device
it was found that vlan tagged traffic is dropped on chip.
The reason is that bridge device enables promisc mode,
but in atlantic chip vlan filters will still apply.
So we have to corellate promisc settings with vlan configuration.
The solution is to track in a separate state variable the
need of vlan forced promisc. And also consider generic
promisc configuration when doing vlan filter config.

We should rather have vlan_tci filled all the way down
to the transmitting netdevice and let it do the hw/sw
vlan implementation.

We build vlan on top of bonding interface, which vlan offload
is off, bond mode is 802.3ad (LACP) and xmit_hash_policy is
BOND_XMIT_POLICY_ENCAP34.
Because vlan tx offload is off, vlan tci is cleared and skb push
the vlan header in validate_xmit_vlan() while sending from vlan
devices. Then in bond_xmit_hash, __skb_flow_dissect() fails to
get information from protocol headers encapsulated within vlan,
because 'nhoff' is points to IP header, so bond hashing is based
on layer 2 info, which fails to distribute packets across slaves.
This patch always enable bonding's vlan tx offload, pass the vlan
packets to the slave devices with vlan tci, let them to handle
vlan implementation.

This patch fixes the MAC address setup in the probe. The MAC address
retrieved using of_get_mac_address was checked for not containing an
error, but it may also be NULL which wasn't tested. Fix it by replacing
IS_ERR with IS_ERR_OR_NULL.

Since commit 605ad7f184b60cfaacbc038aa6c55ee68dee3c89 "tcp: refine TSO autosizing",
outbound throughput is dramatically reduced for some connections, as sis900
is doing TX completion within idle states only.
Make TX completion happen after every transmitted packet.

When transmitting certain PTP frames, e.g. SYNC and DELAY_REQ, the
PTP daemon, e.g. ptp4l, is polling the driver for the frame transmit
hardware timestamp. The polling will most likely timeout if the tx
coalesce is enabled due to the Interrupt-on-Completion (IC) bit is
not set in tx descriptor for those frames.
This patch will ignore the tx coalesce parameter and set the IC bit
when transmitting PTP frames which need to report out the frame
transmit hardware timestamp to user space.
