The AFU Information DVSEC capability is a means to extract common,
general information about all of the AFUs associated with a Function
independent of the specific functionality that each AFU provides.
Write in the AFU Index field allows to access to the descriptor data
for each AFU.
With the current code, we are not able to access to these specific data
when the index >= 1 because we are writing to the wrong location.
All requests to the data of each AFU are pointing to those of the AFU 0,
which could have impacts when using a card with more than one AFU per
function.
This patch fixes the access to the AFU Descriptor Data indexed by the
AFU Info Index field.

Disable interrupts while configuring the transfer and enable them back.
We have below as the programming sequence
1. start and slave address
2. byte count and stop
In some customer platform there was a lot of interrupts between 1 and 2
and after slave address (around 7 clock cyles) if 2 is not executed
then the transaction is nacked.
To fix this case make the 2 writes atomic.

Commit fe8e93504ce8 ("irqchip/gic-v3-its: Use full range of LPIs"), removes
the cap for lpi_id_bits, which causes the following warning to trigger on a

Firmware can provide zero as values for sustained performance level and
corresponding sustained frequency in kHz in order to hide the actual

Commit 12864ff8545f (ACPI / LPSS: Avoid PM quirks on suspend and resume
from hibernation) bypasses lpss quirks for S3 and S4, by setting a flag
for S3/S4 in acpi_lpss_suspend(), and check that flag in
acpi_lpss_resume().
But this overlooks the boot case where acpi_lpss_resume() may get called
without a corresponding acpi_lpss_suspend() having been called.
Thus force setting the flag during boot.

Calling dmi_check_system() early only works on X86. Other
architectures initialize the DMI subsystem later so it's not
ready yet when ACPI itself gets initialized.
In the best case it results in a useless call to a function which
will do nothing. But depending on the dmi implementation, it could
also result in warnings. Best is to not call the function when it
can't work and isn't needed.
Additionally, if anyone ever needs to add non-x86 quirks, it would
surprisingly not work, so document the limitation to avoid confusion.

That VM_BUG_ON was triggered by the page poisoning introduced in
mm/sparse.c with the git commit d0dc12e86b31 ("mm/memory_hotplug:
optimize memory hotplug").
With the same commit the new 'nid' field has been added to the struct
memory_block in order to store and later on derive the node id for
offline pages (instead of accessing struct page which might be
uninitialized). But one reference to nid in show_valid_zones() function

not be used any more after test_pages_in_a_zone() call, do not update

Johannes Berg says:
====================
Here are quite a large number of fixes, notably:
* various A-MSDU building fixes (currently only affects mt76)
* syzkaller & spectre fixes in hwsim
* TXQ vs. teardown fix that was causing crashes
* embed WMM info in reg rule, bad code here had been causing crashes
* one compilation issue with fix from Arnd (rfkill-gpio includes)
* fixes for a race and bad data during/after channel switch
* nl80211: a validation fix, attribute type & unit fixes
along with other small fixes.

Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number
of MSIX vectors used by RDMA. There is one code path in open that needs
to check the true max_cp_rings including any used by RDMA. This code
is now checking for the reduced max_cp_rings which will fail when the
number of cp rings is very small.
To fix this in a clean way, we don't adjust max_cp_rings anymore.
Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the
reduced max_cp_rings when appropriate.

When the driver detects that resources have changed during open, it
should reset the rx and tx rings to 0. This will properly setup the
init sequence to initialize the default rings again. We also need
to signal the RDMA driver to stop and clear its interrupts. We then
call the RoCE driver to restart if a new set of default rings is
successfully reserved.

commit afb2c4437dae ("drm/i915/ddi: Push pipe clock enabling to encoders")
inadvertently stopped enabling the pipe clock for any DP-MST stream
after the first one. It also rearranged the pipe clock enabling wrt.
initial MST payload allocation step (which may or may not be a
problem, but it's contrary to the spec.).
Fix things by making the above commit truly a non-functional change.

It makes the secondary AOC E2460P monitor connected via DP to an

This trys to give new born vGPU with higher scheduling chance
not only with adding to sched list head and also have higher
priority for workload sched for 2 seconds after starting to
schedule it. In order for fast GPU execution during VM boot,
and ensure guest driver setup with required state given in time.
This fixes recent failure seen on one VM with multiple linux VMs
running on kernel with commit 2621cefaa42b3("drm/i915: Provide a timeout to i915_gem_wait_for_idle() on setup"),
which had shorter setup timeout that caused context state init failed.
v2: change to 2s for higher scheduling period

between.
Issue STOP only when the message is the last one _or_ flagged with

The cpsw-phy-sel device is not a child of the cpsw interconnect target
module. It lives in the system control module.
Let's fix this issue by trying to use cpsw-phy-sel phandle first if it
exists and if not fall back to current usage of trying to find the
cpsw-phy-sel child. That way the phy sel driver can be a child of the
system control module where it belongs in the device tree.
Without this fix, we cannot have a proper interconnect target module
hierarchy in device tree for things like genpd.
Note that deferred probe is mostly not supported by cpsw and this patch
does not attempt to fix that. In case deferred probe support is needed,
this could be added to cpsw_slave_open() and phy_connect() so they start
handling and returning errors.
For documenting it, looks like the cpsw-phy-sel is used for all cpsw device
tree nodes. It's missing the related binding documentation, so let's also
update the binding documentation accordingly.
