Add a test to verify the "MONITOR/MWAIT never fault" quirk, and as a
bonus, also verify the related "MISC_ENABLES ignores ENABLE_MWAIT" quirk.
If the "never fault" quirk is enabled, MONITOR/MWAIT should always be
emulated as NOPs, even if they're reported as disabled in guest CPUID.
Use the MISC_ENABLES quirk to coerce KVM into toggling the MWAIT CPUID
enable, as KVM now disallows manually toggling CPUID bits after running

Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged
here for calculating the size of the destination buffer (0x10 instead of
0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with
the source and dest being struct fw_section_info_st, so the memcpy should
be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's
responsibility to figure out.
Avoid the whole thing and just do a direct assignment. This results in
no change to the executable code.

with direct assignment") which was applied to net-next.]

For RISC-V platforms we permit assigning addresses from 0 to PCI devices,
both in the memory and the I/O bus space, and we happily do so if there
is no conflict, e.g.:
pci 0000:07:00.0: BAR 0: assigned [io 0x0000-0x0007]
pci 0000:07:00.1: BAR 0: assigned [io 0x0008-0x000f]
pci 0000:06:01.0: PCI bridge to [bus 07]
pci 0000:06:01.0: bridge window [io 0x0000-0x0fff]
(with the SiFive HiFive Unmatched RISC-V board and a dual serial port
option card based on the OxSemi OXPCIe952 device wired for the legacy
UART mode).
Address 0 is treated specially however in many places, for example in
`pci_iomap_range' and `pci_iomap_wc_range' we require that the start
address is non-zero, and even if we let such an address through, then
individual device drivers could reject a request to handle a device at
such an address, such as in `uart_configure_port'. Consequently given
devices configured as shown above only one is actually usable:
Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled
serial 0000:07:00.0: enabling device (0000 -> 0001)
serial: probe of 0000:07:00.0 failed with error -12
serial 0000:07:00.1: enabling device (0000 -> 0001)
serial 0000:07:00.1: detected caps 00000700 should be 00000500
0000:07:00.1: ttyS0 at I/O 0x8 (irq = 39, base_baud = 15625000) is a 16C950/954
Therefore avoid handing out address 0, by bumping the lowest address
available to PCI via PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM up by 4 and 16
respectively, which is the minimum allocation size for I/O and memory
BARs.
With this in place the system in question we have:
pci 0000:07:00.0: BAR 0: assigned [io 0x1000-0x1007]
pci 0000:07:00.1: BAR 0: assigned [io 0x1008-0x100f]
pci 0000:06:01.0: PCI bridge to [bus 07]
pci 0000:06:01.0: bridge window [io 0x1000-0x1fff]
and then devices work correctly:
Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled
serial 0000:07:00.0: enabling device (0000 -> 0001)
serial 0000:07:00.0: detected caps 00000700 should be 00000500
0000:07:00.0: ttyS0 at I/O 0x1000 (irq = 38, base_baud = 15625000) is a 16C950/954
serial 0000:07:00.1: enabling device (0000 -> 0001)
serial 0000:07:00.1: detected caps 00000700 should be 00000500
0000:07:00.1: ttyS1 at I/O 0x1008 (irq = 39, base_baud = 15625000) is a 16C950/954
Especially I/O space ranges are particularly valuable, because bridges
only decode bits from 12 up and consequently where 16-bit addressing is
in effect, as few as 16 separate ranges can be assigned to individual
buses only, however a generic change to avoid handing out address 0 only
has turned out controversial as per the discussion referred via the link
below.
Conversely sorting this out in platform code has been standard practice
since forever to avoid a clash with legacy devices subtractively decoded
by the southbridge where present. This can be revised should a generic
solution be adopted sometime.

coresight devices track their connections (output connections) and
hold a reference to the fwnode. When a device goes away, we walk through
the devices on the coresight bus and make sure that the references
are dropped. This happens both ways:
a) For all output connections from the device, drop the reference to
the target device via coresight_release_platform_data()
b) Iterate over all the devices on the coresight bus and drop the
reference to fwnode if *this* device is the target of the output
connection, via coresight_remove_conns()->coresight_remove_match().
However, the coresight_remove_match() doesn't clear the fwnode field,
after dropping the reference, this causes use-after-free and
additional refcount drops on the fwnode.
e.g., if we have two devices, A and B, with a connection, A -> B.
If we remove B first, B would clear the reference on B, from A
via coresight_remove_match(). But when A is removed, it still has
a connection with fwnode still pointing to B. Thus it tries to drops
the reference in coresight_release_platform_data(), raising the bells
like :

Remove the RTC and UART fixed clocks, as these were introduced to
temporarily provide a dummy clock to devices: since the two 26M/32K
fixed oscillators clocks (which do really exist in the SoC) have
been added, there's no reason to keep the aforementioned (and now
redundant) dummies in this devicetree.
In order to remove the uart dummy clock, it was necessary to also
reassign the clock of all UART nodes to clk26m.

At least on commercial devices like some smartphones, the bootloader
will initialize the SoC watchdog and set it to reboot the board when
it times out. The last pet that this watchdog is getting is right
before booting the kernel and left it enabled as a protection against
boot failure: this means that Linux is expected to initialize this
device and pet as soon as possible, or it will bark and reset the AP.
In order to prevent that, add the required watchdog node as default
enabled: this will have no side effects on boards that are not
performing the aforementioned watchdog setup before booting Linux.

MMIO devices should be inside of a soc bus node, as it's done for the
vast majority of ARM64 devicetrees, and for almost all MTK devicetrees.
Create a simple-bus soc node and move all devices with a MMIO address
space in there.

The IOMMU driver now looks for the "mediatek,infracfg" phandle as a
new way to retrieve a syscon to that:
even though the old way is retained, it has been deprecated and the
driver will write a message in kmsg advertising to use the phandle
way instead.
For this reason, assign the right phandle to mediatek,infracfg in
the iommu node.

The entry-method property of the idle-states node should be "psci" as
described in the idle-states binding, since this is already the value of
enable-method in the CPU nodes. Fix it to get rid of a dtbs_check
warning.

Tweak the name of the idle-states subnodes so that they follow the
binding pattern, getting rid of dtbs_check warnings.
Only the usage of "-" in the name was necessary, but "off" was also
exchanged for "sleep" since that seems to be a more common wording in
other dts files.

In commit
4e8988c634 ("soc: mediatek: add DDP_DOMPONENT_DITHER0 enum for mt8195 vdosys0")
the enum mtk_ddp_comp_id was modified to add an index number to the
DITHER component because some new SoCs have multiple dither blocks.
As a result, all of the mutex mod arrays have been changed to use the
new definition instead of the old one (even if that's retained): for
consistency purposes, follow the same trend on the newly introduced
MT8365 mutex mod array.
This commit brings no functional changes.

This driver will get support for more SoCs and the list of infracfg
compatibles is expected to grow: in order to prevent getting this
situation out of control and see a long list of compatible strings,
add support to retrieve a handle to infracfg's regmap through a
new "mediatek,infracfg" phandle.
In order to keep retrocompatibility with older devicetrees, the old
way is kept in place.

When many devices share the same iova domain, iommu_dma_init_domain()
may be called at the same time. The checking of iovad->start_pfn will
all get false in iommu_dma_init_domain() and both enter init_iova_domain()
to do iovad initialization.
Fix this by protecting init_iova_domain() with iommu_dma_cookie->mutex.
