- Add pci_is_vga() helper, which checks for both PCI_CLASS_DISPLAY_VGA and
PCI_CLASS_NOT_DEFINED_VGA (which catches ancient devices built before
Class Codes were defined) (Sui Jingfeng)
- Use the new pci_is_vga() to identify devices for the VGA arbiter, the
sysfs "boot_vga" attribute, and the virtio and qxl drivers (SUi Jingfeng)
* pci/vga:
drm/qxl: Use pci_is_vga() to identify VGA devices
drm/virtio: Use pci_is_vga() to identify VGA devices
PCI/sysfs: Enable 'boot_vga' attribute via pci_is_vga()
PCI/VGA: Select VGA devices earlier
PCI/VGA: Use pci_is_vga() to identify VGA devices
PCI: Add pci_is_vga() helper
The PCI Code and ID Assignment spec, r1.15, secs 1.4 and 1.1, define
VGA Base Class and Sub-Classes:
03 00 PCI_CLASS_DISPLAY_VGA VGA-compatible or 8514-compatible
00 01 PCI_CLASS_NOT_DEFINED_VGA VGA-compatible (before Class Code)
Add a pci_is_vga() helper to return true if a device is in either category.
These VGA devices use the hardwired legacy VGA resources
([mem 0xa0000-0xbffff], [io 0x3b0-0x3bb], [io 0x3c0-0x3df] and aliases), so
they require special handling if more than one is present in the system.

There is no function to get all PCI devices in a system by matching
against the base class code only, ignoring the sub-class code and
the programming interface. Add pci_get_base_class() to suit the
need.
For example, if a driver wants to process all PCI display devices in
a system, it can do so like this:
pdev = NULL;
while ((pdev = pci_get_base_class(PCI_BASE_CLASS_DISPLAY, pdev))) {
do_something_for_pci_display_device(pdev);
}

was sent to me. Because it caused pretty bad selftest failures in
some configurations, I decided to squash in the fix. So, while the
exact commit ids haven't been in linux-next, the code has (from the
kvm-x86 tree).

action specific data without needing to constantly update the main handlers.
* Drop unused function declarations
Selftests:
* Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
* Add support for printf() in guest code and covert all guest asserts to use
printf-based reporting
* Clean up the PMU event filter test and add new testcases
* Include x86 selftests in the KVM x86 MAINTAINERS entry

The KSZ9477 errata points out (in 'Module 4') the link up/down problems
when EEE (Energy Efficient Ethernet) is enabled in the device to which
the KSZ9477 tries to auto negotiate.
The suggested workaround is to clear advertisement of EEE for PHYs in
this chip driver.
To avoid regressions with other switch ICs the new MICREL_NO_EEE flag
has been introduced.
Moreover, the in-register disablement of MMD_DEVICE_ID_EEE_ADV.MMD_EEE_ADV
MMD register is removed, as this code is both; now executed too late
(after previous rework of the PHY and DSA for KSZ switches) and not
required as setting all members of eee_broken_modes bit field prevents
the KSZ9477 from advertising EEE.

fscrypt support to CephFS! The list of things which don't work with
encryption should be fairly short, mostly around the edges: fallocate
(not supported well in CephFS to begin with), copy_file_range (requires
re-encryption), non-default striping patterns.
This was a multi-year effort principally by Jeff Layton with assistance
from Xiubo Li, Luís Henriques and others, including several dependant
changes in the MDS, netfs helper library and fscrypt framework itself.

MIPS, LoongArch and some other architectures have many holes between
different segments and the valid address space (256T available) is
insufficient to map all these segments to kasan shadow memory with the
common formula provided by kasan core. So we need architecture specific
mapping formulas to ensure different segments are mapped individually,
and only limited space lengths of those specific segments are mapped to
shadow.
Therefore, when the incoming address is converted to a shadow, we need
to add a condition to determine whether it is valid.

Similar to the syndrome calculation, the recovery algorithms also work
on 64 bytes at a time to align with the L1 cache line size of current
and future LoongArch cores (that we care about). Which means
unrolled-by-4 LSX and unrolled-by-2 LASX code.
The assembly is originally based on the x86 SSSE3/AVX2 ports, but
register allocation has been redone to take advantage of LSX/LASX's 32
vector registers, and instruction sequence has been optimized to suit
(e.g. LoongArch can perform per-byte srl and andi on vectors, but x86
cannot).
Performance numbers measured by instrumenting the raid6test code, on a
3A5000 system clocked at 2.5GHz:
> lasx 2data: 354.987 MiB/s
> lasx datap: 350.430 MiB/s
> lsx 2data: 340.026 MiB/s
> lsx datap: 337.318 MiB/s
> intx1 2data: 164.280 MiB/s
> intx1 datap: 187.966 MiB/s
Because recovery algorithms are chosen solely based on priority and
availability, lasx is marked as priority 2 and lsx priority 1. At least
for the current generation of LoongArch micro-architectures, LASX should
always be faster than LSX whenever supported, and have similar power
consumption characteristics (because the only known LASX-capable uarch,
the LA464, always compute the full 256-bit result for vector ops).

The algorithms work on 64 bytes at a time, which is the L1 cache line
size of all current and future LoongArch cores (that we care about), as
confirmed by Huacai. The code is based on the generic int.uc algorithm,
unrolled 4 times for LSX and 2 times for LASX. Further unrolling does
not meaningfully improve the performance according to experiments.
Performance numbers measured during system boot on a 3A5000 @ 2.5GHz:
> raid6: lasx gen() 12726 MB/s
> raid6: lsx gen() 10001 MB/s
> raid6: int64x8 gen() 2876 MB/s
> raid6: int64x4 gen() 3867 MB/s
> raid6: int64x2 gen() 2531 MB/s
> raid6: int64x1 gen() 1945 MB/s
Comparison of xor() speeds (from different boots but meaningful anyway):
> lasx: 11226 MB/s
> lsx: 6395 MB/s
> int64x4: 2147 MB/s
Performance as measured by raid6test:

These are not valid symbols so drop the '%' prefix.
Alternatively we could use %PHYLINK_PCS_NEG_\* (escape the *)

team interface has used a dynamic lockdep key to avoid false-positive
lockdep deadlock detection. Virtual interfaces such as team usually
have their own lock for protecting private data.
These interfaces can be nested.
team0
|
team1
Each interface's lock is actually different(team0->lock and team1->lock).
So,
mutex_lock(&team0->lock);
mutex_lock(&team1->lock);
mutex_unlock(&team1->lock);
mutex_unlock(&team0->lock);
The above case is absolutely safe. But lockdep warns about deadlock.
Because the lockdep understands these two locks are same. This is a
false-positive lockdep warning.
So, in order to avoid this problem, the team interfaces started to use
dynamic lockdep key. The false-positive problem was fixed, but it
introduced a new problem.
When the new team virtual interface is created, it registers a dynamic
lockdep key(creates dynamic lockdep key) and uses it. But there is the
limitation of the number of lockdep keys.
So, If so many team interfaces are created, it consumes all lockdep keys.
Then, the lockdep stops to work and warns about it.
In order to fix this problem, team interfaces use the subclass instead
of the dynamic key. So, when a new team interface is created, it doesn't
register(create) a new lockdep, but uses existed subclass key instead.
It is already used by the bonding interface for a similar case.
As the bonding interface does, the subclass variable is the same as
the 'dev->nested_level'. This variable indicates the depth in the stacked
interface graph.
The 'dev->nested_level' is protected by RTNL and RCU.
So, 'mutex_lock_nested()' for 'team->lock' requires RTNL or RCU.
In the current code, 'team->lock' is usually acquired under RTNL, there is
no problem with using 'dev->nested_level'.
The 'team_nl_team_get()' and The 'lb_stats_refresh()' functions acquire
'team->lock' without RTNL.
But these don't iterate their own ports nested so they don't need nested
lock.
Reproducer:
for i in {0..1000}
do
ip link add team$i type team
ip link add dummy$i master team$i type dummy
ip link set dummy$i up
ip link set team$i up
done
Splat looks like:

Adds a new line to the docstrings of functions wrapping __xa_alloc() and
__xa_alloc_cyclic(), informing about the necessity of flag XA_FLAGS_ALLOC
being set previously.
The documentation so far says that functions wrapping __xa_alloc() and
__xa_alloc_cyclic() are supposed to return either -ENOMEM or -EBUSY in
case of an error. If the xarray has been initialized without the flag
XA_FLAGS_ALLOC, however, they fail with a different, undocumented error
code.
As hinted at in Documentation/core-api/xarray.rst, wrappers around these
functions should only be invoked when the flag has been set. The
functions' documentation should reflect that as well.

...
Support for booting the iMX remoteprocs using MMIO, instead of SMCCC is
added. The iMX driver is also extended to support delivering interrupts
from an arbitrary number of vdev.
Support is added to the TI PRU driver, to allow GPMUX to be controlled
from DeviceTree.
The Qualcomm coredump collector is extended to fall back to generating a
full coredump, in the case that the loaded firmware doesn't support
generating minidump. The overly terse MD abbreviation of "MINIDUMP" is
expanded, to make the code easier on the eye.
The list of Qualcomm Sensor Low Power Island (SLPI) instances supported
is cleaned up, and SDM845 is added. SDM630/636/660 support for the modem
subsystem (mss) is added.
All the Qualcomm drivers are transitioned to of_reserved_mem_lookup()
instead of open coding the resolution of reserved-memory regions, to
gain handling of error cases. A couple of drivers are transitioned to
use devm_platform_ioremap_resource_byname().
The stm32 remoteproc driver's PM operations are updated to modern
macros, to avoid the "unused variable"-warning in some configurations.
Drivers are transitioned away from directly including of_device.h.

Previously, the defines for phy_device flags in the Micrel driver were
ambiguous in their representation. They were intended to be bit masks
but were mistakenly defined as bit positions. This led to the following
issues:
- MICREL_KSZ8_P1_ERRATA, designated for KSZ88xx switches, overlapped
with MICREL_PHY_FXEN and MICREL_PHY_50MHZ_CLK.
- Due to this overlap, the code path for MICREL_PHY_FXEN, tailored for
the KSZ8041 PHY, was not executed for KSZ88xx PHYs.
- Similarly, the code associated with MICREL_PHY_50MHZ_CLK wasn't
triggered for KSZ88xx.
To rectify this, all three flags have now been explicitly converted to
use the `BIT()` macro, ensuring they are defined as bit masks and
preventing potential overlaps in the future.

This helper allows the driver change the dma mode to premapped mode.
Under the premapped mode, the virtio core do not do dma mapping
internally.
This just work when the use_dma_api is true. If the use_dma_api is false,
the dma options is not through the DMA APIs, that is not the standard
way of the linux kernel.
