The UEFI spec does not mention or reason about the configured size of
the virtual address space at all, but it does mention that all memory
should be identity mapped using a page size of 4 KiB.
This means that a LPA2 capable system that has any system memory outside
of the 48-bit addressable physical range and follows the spec to the
letter may serve page allocation requests from regions of memory that
the kernel cannot access unless it was built with LPA2 support and
enables it at runtime.
So let's ensure that all page allocations are limited to the 48-bit
range.

Pull EFI fix from Ard Biesheuvel:
"A single revert for some code that I added during this cycle. The code
is not wrong, but it should be a bit more careful about how to handle
the shadow call stack pointer, so it is better to revert it for now
and bring it back later in improved form.

arm64: efi: Revert "Recover from synchronous exceptions ..."
This reverts commit 23715a26c8d81291, which introduced some code in
assembler that manipulates both the ordinary and the shadow call stack
pointer in a way that could potentially be taken advantage of. So let's
revert it, and do a better job the next time around.

The Hantro G2 video decoder block sits behind the IOMMU. Without a
reference for the system to properly configure the IOMMU, it will fault
and cause the video decoder to fail.
Add a proper reference to the IOMMU port. The master ID is taken from
the IOMMU fault error message on Linux, and the number seems to match
the order in the user manual's IOMMU diagram.

The 0-day bot reports that arm64 builds with CONFIG_CFI_CLANG +
CONFIG_FTRACE are broken when CONFIG_FUNCTION_GRAPH_TRACER is not
enabled:
ld.lld: error: undefined symbol: __kcfi_typeid_ftrace_stub_graph
>>> referenced by entry-ftrace.S:299 (arch/arm64/kernel/entry-ftrace.S:299)
>>> arch/arm64/kernel/entry-ftrace.o:(.text+0x48) in archive vmlinux.a
This is caused by ftrace_stub_graph using SYM_TYPE_FUNC_START when
the address of the function is not taken in any C translation unit.
Fix the build by only defining ftrace_stub_graph when it's actually
needed, i.e. with CONFIG_FUNCTION_GRAPH_TRACER.

This is the first time we've added an SMBIOS based quirk on arm64,
but fortunately, we can just call a EFI protocol to grab the type #1

Currently, when mapping the EFI runtime regions in the EFI page tables,
we complain about misaligned regions in a rather noisy way, using
WARN().
Not only does this produce a lot of irrelevant clutter in the log, it is
factually incorrect, as misaligned runtime regions are actually allowed
by the EFI spec as long as they don't require conflicting memory types
within the same 64k page.
So let's drop the warning, and tweak the code so that we
- take both the start and end of the region into account when checking
for misalignment
- only revert to RWX mappings for non-code regions if misaligned code
regions are also known to exist.

Currently, arm64, RISC-V and LoongArch rely on the fact that struct
screen_info can be accessed directly, due to the fact that the EFI stub
and the core kernel are part of the same image. This will change after a
future patch, so let's ensure that the screen_info handling is able to
deal with this, by adopting the arm32 approach of passing it as a
configuration table. While at it, switch to ACPI reclaim memory to hold
the screen_info data, which is more appropriate for this kind of
allocation.

To allow efi_enter_kernel() to be shared with the EFI zboot decompressor
build, drop another reference to dcache_clean_poc() and replace it with
a single DC CVAC* instruction. To ensure that it covers the remainder of
efi_enter_kernel() as intended, reorganize the code a bit so it fits in
a 32-byte cacheline, and align it to 32 bytes. (Even though the
architecture defines 16 as the minimum D-cache line size, even the
chosen value of 32 is highly unlikely to ever be encountered on real
hardware, and this works with any line size >= 32)

Commit 2e8cff0a0eee87b2 ("arm64: fix rodata=full") addressed a couple of
issues with the rodata= kernel command line option, which is not a
simple boolean on arm64, and inadvertently got broken due to changes in
the generic bool handling.
Unfortunately, the resulting code never clears the rodata_full boolean
variable if it defaults to true and rodata=on or rodata=off is passed,
as the generic code is not aware of the existence of this variable.
Given the way this code is plumbed together, clearing rodata_full when
returning false from arch_parse_debug_rodata() may result in
inconsistencies if the generic code decides that it cannot parse the
right hand side, so the best way to deal with this is to only take
rodata_full in account if rodata_enabled is also true.

used to select few compat cpufeatures (vfp, crc32, ...) are masked and
hence such hwcaps do not appear in /proc/cpuinfo anymore for PER_LINUX32
personality.
Add the ID register structures explicitly and set the relevant entry as
visible. As these ID registers are now of type visible so make them
available in 64-bit userspace by making necessary changes in register
emulation logic and documentation.
While at it, update the comment for structure ftr_generic_32bits[] which
lists the ID register that use it.

Unlike x86, which has machinery to deal with page faults that occur
during the execution of EFI runtime services, arm64 has nothing like
that, and a synchronous exception raised by firmware code brings down
the whole system.
With more EFI based systems appearing that were not built to run Linux
(such as the Windows-on-ARM laptops based on Qualcomm SOCs), as well as
the introduction of PRM (platform specific firmware routines that are
callable just like EFI runtime services), we are more likely to run into
issues of this sort, and it is much more likely that we can identify and
work around such issues if they don't bring down the system entirely.
Since we already use a EFI runtime services call wrapper in assembler,
we can quite easily add some code that captures the execution state at
the point where the call is made, allowing us to revert to this state
and proceed execution if the call triggered a synchronous exception.
Given that the kernel and the firmware don't share any data structures
that could end up in an indeterminate state, we can happily continue
running, as long as we mark the EFI runtime services as unavailable from
that point on.

Armv8 Juno fix for v6.1
Just a single fix to add the missing critical points in the thermal
zones that has been mandatory in the binding but was enforced in the
code recently.

arm64: dts: juno: Add thermal critical trip points

The trapping of SMPRI_EL1 and TPIDR2_EL0 currently only really
work on nVHE, as only this mode uses the fine-grained trapping
that controls these two registers.
Move the trapping enable/disable code into
__{de,}activate_traps_common(), allowing it to be called when it
actually matters on VHE, and remove the flipping of EL2 control
for TPIDR2_EL0, which only affects the host access of this
register.

When thermnal zones are defined, trip points definitions are mandatory.
Define a couple of critical trip points for monitoring of existing
PMIC and SOC thermal zones.
This was lost between txt to yaml conversion and was re-enforced recently
via the commit 8c596324232d ("dt-bindings: thermal: Fix missing required property")
