This will allow IOMMU drivers to be loaded as EL2 modules
To achieve that, EL2 module init should register and init
the driver using pkvm_iommu_driver_init.
To avoid having to hardcode S2MPU drivers in IOMMU EL2 code,
pkvm_iommu_driver_init will have a ptr to driver struct instead of
id.
Id is removed from pkvm_iommu_driver and the address of the struct
is treated as the id of the driver, the kernel is expected to pass
linear mapping address of the driver and the hypervisor is expected
to use hyp address.

commit 44035ec2fd upstream.
There's been a very long running bug that seems to have been neglected for
a while, where amdgpu consistently triggers a KASAN error at start:
BUG: KASAN: global-out-of-bounds in read_indirect_azalia_reg+0x1d4/0x2a0 [amdgpu]
Read of size 4 at addr ffffffffc2274b28 by task modprobe/1889
After digging through amd's rather creative method for accessing registers,
I eventually discovered the problem likely has to do with the fact that on
my dce120 GPU there are supposedly 7 sets of audio registers. But we only
define a register mapping for 6 sets.
So, fix this and fix the KASAN warning finally.

commit c48c8b829d upstream.
Although setting the affinity of an interrupt to a set of CPUs that doesn't
have any online CPU is generally frowned apon, there are a few limited
cases where such affinity is set from a CPUHP notifier, setting the
affinity to a CPU that isn't online yet.
The saving grace is that this is always done using the 'force' attribute,
which gives a hint that the affinity setting can be outside of the online
CPU mask and the callsite set this flag with the knowledge that the
underlying interrupt controller knows to handle it.
This restores the expected behaviour on Marek's system.

commit 33de0aa4ba upstream.
[ Fixed small conflicts due to the HK_FLAG_MANAGED_IRQ flag been
renamed on upstream ]
When booting with maxcpus=<small number> (or even loading a driver
while most CPUs are offline), it is pretty easy to observe managed
affinities containing a mix of online and offline CPUs being passed
to the irqchip driver.
This means that the irqchip cannot trust the affinity passed down
from the core code, which is a bit annoying and requires (at least
in theory) all drivers to implement some sort of affinity narrowing.
In order to address this, always limit the cpumask to the set of
online CPUs.

When booting with maxcpus=<small number>, interrupt controllers
such as the GICv3 ITS may not be able to satisfy the affinity of
some managed interrupts, as some of the HW resources are simply
not available.
The same thing happens when loading a driver using managed interrupts
while CPUs are offline.
In order to deal with this, do not try to activate such interrupt
if there is no online CPU capable of handling it. Instead, place
it in shutdown state. Once a capable CPU shows up, it will be
activated.

that it doesn't. As of commit 57365a04c9 ("iommu: Move bus setup to

GPU driver should be responsible for its own behaviour anyway. Make the

Commit 3ae86d2d47 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock

to manually toggle the fn-lock LED because the EC does not do it itself.
However, the same WMI ID is also sent on some Yoga laptops. Here, setting
the fn-lock state is not valid behavior, and causes the EC to spam

[ Upstream commit 7dd12d65ac ]
When an IO error occurs, the function __zonefs_io_error() is used to
issue a zone report to obtain the latest zone information from the
device. This function gets a zone report for all zones used as storage
for a file, which is always 1 zone except for files representing
aggregated conventional zones.
The number of zones of a zone report for a file is calculated in
__zonefs_io_error() by doing a bit-shift of the inode i_zone_size field,
which is equal to or larger than the device zone size. However, this
calculation does not take into account that the last zone of a zoned
device may be smaller than the zone size reported by bdev_zone_sectors()
(which is used to set the bit shift size). As a result, if an error
occurs for an IO targetting such last smaller zone, the zone report will
ask for 0 zones, leading to an invalid zone report.
Fix this by using the fact that all files require a 1 zone report,
except if the inode i_zone_size field indicates a zone size larger than
the device zone size. This exception case corresponds to a mount with
aggregated conventional zones.
A check for this exception is added to the file inode initialization
during mount. If an invalid setup is detected, emit an error and fail
the mount (check contributed by Johannes Thumshirn).

[ Upstream commit 5e29500eba ]
When Xen domain configures MSI-X, the usual approach is to enable MSI-X
together with masking all of them via the config space, then fill the
table and only then clear PCI_MSIX_FLAGS_MASKALL. Allow doing this via
QEMU running in a stub domain.
Previously, when changing PCI_MSIX_FLAGS_MASKALL was not allowed, the
whole write was aborted, preventing change to the PCI_MSIX_FLAGS_ENABLE
bit too.
Note the Xen hypervisor intercepts this write anyway, and may keep the
PCI_MSIX_FLAGS_MASKALL bit set if it wishes to. It will store the
guest-requested state and will apply it eventually.

Like on the Acer Switch 10 SW5-012, the Acer Switch V 10 SW5-017's _LID
method messes with home- and power-button GPIO IRQ settings, causing an
IRQ storm.
Add a quirk entry for the Acer Switch V 10 to the dmi_use_low_level_irq[]
DMI quirk list, to use low-level IRQs on this model, fixing the IRQ storm.

[ Upstream commit 8e9ada1d0e ]
It seems that the Windows drivers for the ACPI0011 soc_button_array
device use low level triggered IRQs rather then using edge triggering.
Some ACPI tables depend on this, directly poking the GPIO controller's
registers to clear the trigger type when closing a laptop's/2-in-1's lid
and re-instating the trigger when opening the lid again.
Linux sets the edge/level on which to trigger to both low+high since
it is using edge type IRQs, the ACPI tables then ends up also setting
the bit for level IRQs and since both low and high level have been
selected by Linux we get an IRQ storm leading to soft lockups.
As a workaround for this the soc_button_array already contains
a DMI quirk table with device models known to have this issue.
Add a module parameter for this so that users can easily test if their
device is affected too and so that they can use the module parameter
as a workaround.

[ Upstream commit c7e37cc624 ]
On ACPI systems (irq_pin_access_method == IRQ_PIN_ACCESS_ACPI_*) the driver
does not reset the controller at probe time, because sometimes the system
firmware loads a config and resetting might loose this config.
On the Nanote UMPC-01 device OTOH the config is in flash of the controller,
the controller needs a reset to load this; and the system firmware does not
reset the controller on a cold boot.
To fix the Nanote UMPC-01 touchscreen not working on a cold boot, try
resetting the controller and then re-reading the config when encountering
a config with 0 width/height/max_touch_num value and the controller has
not already been reset by goodix_ts_probe().
This should be safe to do in general because normally we should never
encounter a config with 0 width/height/max_touch_num. Doing this in
general not only avoids the need for a DMI quirk, but also might help
other systems.

[ Upstream commit 038ee49fef ]
RS485-enabled UART ports on TI Sitara SoCs with active-low polarity
exhibit a Transmit Enable glitch on ->set_termios():
omap8250_restore_regs(), which is called from omap_8250_set_termios(),
sets the TCRTLR bit in the MCR register and clears all other bits,
including RTS. If RTS uses active-low polarity, it is now asserted
for no reason.
The TCRTLR bit is subsequently cleared by writing up->mcr to the MCR
register. That variable is always zero, so the RTS bit is still cleared
(incorrectly so if RTS is active-high).
(up->mcr is not, as one might think, a cache of the MCR register's
current value. Rather, it only caches a single bit of that register,
the AFE bit. And it only does so if the UART supports the AFE bit,
which OMAP does not. For details see serial8250_do_set_termios() and
serial8250_do_set_mctrl().)
Finally at the end of omap8250_restore_regs(), the MCR register is
restored (and RTS deasserted) by a call to up->port.ops->set_mctrl()
(which equals serial8250_set_mctrl()) and serial8250_em485_stop_tx().
So there's an RTS glitch between setting TCRTLR and calling
serial8250_em485_stop_tx(). Avoid by using a read-modify-write
when setting TCRTLR.
While at it, drop a redundant initialization of up->mcr. As explained
above, the variable isn't used by the driver and it is already
initialized to zero because it is part of the static struct
serial8250_ports[] declared in 8250_core.c. (Static structs are
initialized to zero per section 6.7.8 nr. 10 of the C99 standard.)

commit 4dbd6a3e90 upstream.
Current code re-calculates the size after aligning the starting and
ending physical addresses on a page boundary. But the re-calculation
also embeds the masking of high order bits that exceed the size of
the physical address space (via PHYSICAL_PAGE_MASK). If the masking
removes any high order bits, the size calculation results in a huge
value that is likely to immediately fail.
Fix this by re-calculating the page-aligned size first. Then mask any
high order bits using PHYSICAL_PAGE_MASK.
