RZ/G3E SMARC EVK has 3 user buttons called USER_SW1, USER_SW2 and
USER_SW3 and SLEEP button with NMI support. Add a DT node in device tree
to instantiate the gpio-keys driver for these buttons.
The system can enter into STR state by pressing the sleep button and
wakeup from STR is done by pressing power button. The USER_SW{1,2,3}
configured as wakeup-source, so it can wakeup the system during s2idle.

Pull CPU speculation fixes from Borislav Petkov:
"Add the mitigation logic for Transient Scheduler Attacks (TSA)
TSA are new aspeculative side channel attacks related to the execution
timing of instructions under specific microarchitectural conditions.
In some cases, an attacker may be able to use this timing information
to infer data from other contexts, resulting in information leakage.
Add the usual controls of the mitigation and integrate it into the
existing speculation bugs infrastructure in the kernel"

Introduce a new KVM capability to expose to the userspace whether
cacheable mapping of PFNMAP is supported.
The ability to safely do the cacheable mapping of PFNMAP is contingent
on S2FWB and ARM64_HAS_CACHE_DIC. S2FWB allows KVM to avoid flushing
the D cache, ARM64_HAS_CACHE_DIC allows KVM to avoid flushing the icache
and turns icache_inval_pou() into a NOP. The cap would be false if
those requirements are missing and is checked by making use of
kvm_arch_supports_cacheable_pfnmap.
This capability would allow userspace to discover the support.
It could for instance be used by userspace to prevent live-migration
across FWB and non-FWB hosts.

KVM currently forces non-cacheable memory attributes (either Normal-NC
or Device-nGnRE) for a region based on pfn_is_map_memory(), i.e. whether
or not the kernel has a cacheable alias for it. This is necessary in
situations where KVM needs to perform CMOs on the region but is
unnecessarily restrictive when hardware obviates the need for CMOs.
KVM doesn't need to perform any CMOs on hardware with FEAT_S2FWB and
CTR_EL0.DIC. As luck would have it, there are implementations in the
wild that need to map regions of a device with cacheable attributes to
function properly. An example of this is Nvidia's Grace Hopper/Blackwell
systems where GPU memory is interchangeable with DDR and retains
properties such as cacheability, unaligned accesses, atomics and
handling of executable faults. Of course, for this to work in a VM the
GPU memory needs to have a cacheable mapping at stage-2.
Allow cacheable stage-2 mappings to be created on supporting hardware
when the VMA has cacheable memory attributes. Check these preconditions
during memslot creation (in addition to fault handling) to potentially
'fail-fast' as a courtesy to userspace.

Fixes a security bug due to mismatched attributes between S1 and
S2 mapping.
Currently, it is possible for a region to be cacheable in the userspace
VMA, but mapped non cached in S2. This creates a potential issue where
the VMM may sanitize cacheable memory across VMs using cacheable stores,
ensuring it is zeroed. However, if KVM subsequently assigns this memory
to a VM as uncached, the VM could end up accessing stale, non-zeroed data
from a previous VM, leading to unintended data exposure. This is a security
risk.
Block such mismatch attributes case by returning EINVAL when userspace
try to map PFNMAP cacheable. Only allow NORMAL_NC and DEVICE_*.

ee368a10d0df ("ARM: dts: am335x-boneblack.dts: unique gpio-line-names").
gpio0_7 is located on the P9 header on the BBB.

The wiring of the RS-485 transceiver of UART0 of the PDU-001 board
allows sending or receiving date exclusively. In other words: no
character transmitted will ever be received.
Hence the tx-filter counter in the OMAP serial driver can't work
correctly as it relies on receiving the transmitted characters.
This in turn will prevent reception of data unless we disable the
tx-filter counter.
This patch disables the tx-filter counter by enabling the DTS setting
rs485-rx-during-tx. This might sound like the opposite to be done but
it uses the enabling of rs485-rx-during-tx not for receiving the data
transmitted but for disabling the tx-fiter counter.

Despite its name, kvm_is_device_pfn() is actually used to determine if a
given PFN has a kernel mapping that can be used to perform cache
maintenance, as it calls pfn_is_map_memory() internally.
Expand the helper into its single callsite and further condition the
check on the VMA having either VM_PFNMAP or VM_MIXEDMAP set. VMAs that
set neither of these flags must always contain Normal, struct page
backed memory with valid aliases in the kernel address space.

To perform cache maintenance on a region of memory, KVM/arm64 relies on
that region having a cacheable alias in the kernel's address space which
can be used with CMO instructions.
The 'device' variable is somewhat of a misnomer, as it actually
indicates whether or not the stage-2 alias is allowed to have cacheable
memory attributes. The resulting stage-2 memory attributes are further
modified by VM_ALLOW_ANY_UNCACHED, selecting between Normal-NC or
Device-nGnRE depending on what the endpoint supports.
Rename the to s2_force_noncacheable such that its purpose is a bit more
obvious.

UART1 is normally used to connect to the Bluetooth side of a Broadcom
WiFi+BT combo chip. The connection uses 4 pins.
Add pinmux nodes for UART1, one for the RX/TX pins, and one for the
RTS/CTS pins.

Nodes are supposed to be sorted by address, or if no addresses
apply, by node name. The rgmii0 pins are out of order, possibly
due to multiple patches adding pin mux settings conflicting.
Move the rgmii0 pins to the correct location.

qemu-system-m68k -M q800 has an old bug that causes the kernel to
occasionally complain about a soft lockup:
watchdog: BUG: soft lockup - CPU#0 stuck for 5107s!
There isn't any actual lockup. The via1 clocksource produced a large
jump in jiffies, causing the watchdog to detect a stale timestamp.
The 32-bit clocksource counter runs at 783360 Hz and its period is
about 5482 seconds. Applying the "nanosecond" approximation used in
get_timestamp() in kernel/watchdog.c then yields the duration reported
in the log message above (always 5107 or 5108 in my tests):
0xffffffff / VIA_CLOCK_FREQ * 10**9 / 2**30 = 5106.209 seconds
It is notoriously difficult to correctly emulate a MOS6522 VIA chip. So
it seems wise to document the VIA clocksource driver better, especially
those hardware behaviours which the kernel relies upon.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize on
the __ASSEMBLER__ macro that is provided by the compilers now.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), with one comment tweaked manually in
arch/m68k/include/asm/mac_baboon.h (which was missing underscores).

__ASSEMBLY__ is only defined by the Makefile of the kernel, so
this is not really useful for uapi headers (unless the userspace
Makefile defines it, too). Let's switch to __ASSEMBLER__ which

When MACH_IS_MVME147, the boot console calls mvme147_scc_write() to
generate console output. That will continue to work even after
debug_cons_nputs() becomes unavailable so there's no need to
unregister the boot console.
Take the opportunity to remove a repeated MACH_IS_* test. Use the
actual .write method (instead of a wrapper) and test that pointer
instead. This means adding an unused parameter to debug_cons_nputs() for
consistency with the struct console API.
early_printk.c is only built when CONFIG_EARLY_PRINTK=y. As of late,
head.S is only built when CONFIG_MMU_MOTOROLA=y. So let the former symbol
depend on the latter, to obviate some ifdef conditionals.

The cursor home operation is unused and seems undesirable for logging.
Remove it. The console_not_cr label actually means "not line feed and
not carriage return either" so take the opportunity to replace it with
something less confusing. Rectify some inconsistent whitespace while
we're here.
