platform/x86/amd/hsmp: Create separate ACPI, plat and common drivers
Separate the probes for HSMP ACPI and platform device drivers.

Provide a Kconfig option to choose between ACPI or the platform device
based driver. The common code which is the core part of the HSMP driver
maintained at hsmp.c is guarded by AMD_HSMP config and is selected by
these two driver configs. This will be built into separate hsmp_common.ko
module and acpi as hsmp_acpi and plat as amd_hsmp respectively.

Also add "|| COMPILE_TEST" clause in Kconfig to get build coverage for
HSMP.

de6840095f mmc: mtk-sd: add support for mt7988
Add support for mmc on MT7988 SoC.

We can use mt7986 platform data in driver, but mt7988 needs different
clocks so for binding we need own compatible.

24f6425be8 mmc: mtk-sd: Add support for MT8196
Mediatek SoC MT8196 features a new design for tx/rx path. The new tx
path incorporates register settings that are closely associated with
bus timing. And the difference between new rx path and older versions
is the usage of distinct register bits when setting the data sampling
edge as part of the tuning process.

Besides, the register settings for STOP_DLY_SEL and POP_EN_CNT are
different from previous SoCs.

For the changes mentioned in relation to the MT8196, the new compatible
string 'mediatek,mt8196-mmc' is introduced. This is to accommodate
different settings and workflows specific to the MT8196.

312607ba08 mmc: mtk-sd: Add stop_dly_sel and pop_en_cnt to platform data
There are modified register settings for STOP_DLY_SEL and POP_EN_CNT
from our next generation SoCs, due to the advanced chip manufacturing
process and the resulting changes in the internal signal timing.

Add two new fields to the compatibility structure to reflect the
modifications. For legacy SoCs, also add the original value of
'stop_dly_sel' to the platform data, for unified code setting.

82a0fcb1ad s390/kdump: Provide is_kdump_kernel() implementation
s390 sets "elfcorehdr_addr = ELFCORE_ADDR_MAX;" early during
setup_arch() to deactivate the "elfcorehdr= kernel" parameter,
resulting in is_kdump_kernel() returning "false".

During vmcore_init()->elfcorehdr_alloc(), if on a dump kernel and
allocation succeeded, elfcorehdr_addr will be set to a valid address
and is_kdump_kernel() will consequently return "true".

is_kdump_kernel() should return a consistent result during all boot
stages, and properly return "true" if in a kdump environment - just
like it is done on powerpc where "false" is indicated in fadump
environments, as added in commit b098f1c323 ("powerpc/fadump: make
is_kdump_kernel() return false when fadump is active").

Similarly provide a custom is_kdump_kernel() implementation that will only
return "true" in kdump environments, and will do so consistently during
boot.

Update the documentation of dump_available().

8c58a22968 s390/cio: Do not unregister the subchannel based on DNV
Starting with commit 2297791c92 ("s390/cio: dont unregister
subchannel from child-drivers"), CIO does not unregister subchannels
when the attached device is invalid or unavailable. Instead, it
allows subchannels to exist without a connected device. However, if
the DNV value is 0, such as, when all the CHPIDs of a subchannel are
configured in standby state, the subchannel is unregistered, which
contradicts the current subchannel specification.

Update the logic so that subchannels are not unregistered based
on the DNV value. Also update the SCHIB information even if the
DNV bit is zero.

10b8a0cc84 soc: ti: knav_qmss_queue: Use IRQF_NO_AUTOEN flag in request_irq()
As commit cbe16f35be ("genirq: Add IRQF_NO_AUTOEN for request_irq/nmi()")
said, reqeust_irq() and then disable_irq() is unsafe. In the small time gap
between request_irq() and disable_irq(), interrupts can still come.

IRQF_NO_AUTOEN flag can be used by drivers to request_irq(). It prevents
the automatic enabling of the requested interrupt in the same
safe way. With that the usage can be simplified and corrected.

Compile-tested only.

riscv: Prevent a bad reference count on CPU nodes
When populating cache leaves we previously fetched the CPU device node
at the very beginning. But when ACPI is enabled we go through a
specific branch which returns early and does not call 'of_node_put' for
the node that was acquired.

Since we are not using a CPU device node for the ACPI code anyways, we
can simply move the initialization of it just passed the ACPI block, and
we are guaranteed to have an 'of_node_put' call for the acquired node.
This prevents a bad reference count of the CPU device node.

Moreover, the previous function did not check for errors when acquiring
the device node, so a return -ENOENT has been added for that case.

riscv: efi: Set NX compat flag in PE/COFF header
The IMAGE_DLLCHARACTERISTICS_NX_COMPAT informs the firmware that the
EFI binary does not rely on pages that are both executable and
writable.

The flag is used by some distro versions of GRUB to decide if the EFI
binary may be executed.

As the Linux kernel neither has RWX sections nor needs RWX pages for
relocation we should set the flag.

RISC-V: disallow gcc + rust builds
During the discussion before supporting rust on riscv, it was decided
not to support gcc yet, due to differences in extension handling
compared to llvm (only the version of libclang matching the c compiler
is supported). Recently Jason Montleon reported [1] that building with
gcc caused build issues, due to unsupported arguments being passed to
libclang. After some discussion between myself and Miguel, it is better
to disable gcc + rust builds to match the original intent, and
subsequently support it when an appropriate set of extensions can be
deduced from the version of libclang.

riscv: Do not use fortify in early code
Early code designates the code executed when the MMU is not yet enabled,
and this comes with some limitations (see
Documentation/arch/riscv/boot.rst, section "Pre-MMU execution").

FORTIFY_SOURCE must be disabled then since it can trigger kernel panics
as reported in [1].

RISC-V: ACPI: fix early_ioremap to early_memremap
When SVPBMT is enabled, __acpi_map_table() will directly access the
data in DDR through the IO attribute, rather than through hardware
cache consistency, resulting in incorrect data in the obtained ACPI
table.

The log: ACPI: [ACPI:0x18] Invalid zero length.

We do not assume whether the bootloader flushes or not. We should
access in a cacheable way instead of maintaining cache consistency
by software.

ASoC: Intel: sst: Support LPE0F28 ACPI HID
Some old Bay Trail tablets which shipped with Android as factory OS
have the SST/LPE audio engine described by an ACPI device with a
HID (Hardware-ID) of LPE0F28 instead of 80860F28.

Add support for this. Note this uses a new sst_res_info for just
the LPE0F28 case because it has a different layout for the IO-mem ACPI
resources then the 80860F28.

An example of a tablet which needs this is the Vexia EDU ATLA 10 tablet,
which has been distributed to schools in the Spanish Andalucía region.
