Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
This patch chain adds support for the Cirrus Logic cs42l43 PC focused
SoundWire CODEC.

Some configurations differ between chip variants, e,g. the register
to control the on of state of LDOA1 and SWB2. Thus, it is necessary
to choose the correct configuration for a dedicated device.
If the wrong configuration was used, the LDOA1 output that was
disabled by the bootloader was enabled in Kernel again.
Each chip variant gets its dedicated configuration selected by
the chip ID previously collected from MFD probe function.
The VTT enum value (tps65086_regulators) is shifted because not all
chip variants have a separate SWB2 switch. Sometimes they are merged.
So the configuration possibilities differ, thus the regulator
configuration arrays have a different length.

This commit prepares a following commit for the regulator part of the MFD.
The driver should support different device chips that differ in their
register definitions, for instance to control LDOA1 and SWB2.
So it is necessary to use a dedicated regulator description for a
specific device variant. Thus, the content from DEVICEID Register 1 is
used to choose a dedicated configuration between the different device
variants.

Patch series "Add support for DAX vmemmap optimization for ppc64", v6.
This patch series implements changes required to support DAX vmemmap
optimization for ppc64. The vmemmap optimization is only enabled with
radix MMU translation and 1GB PUD mapping with 64K page size.
The patch series also splits the hugetlb vmemmap optimization as a
separate Kconfig variable so that architectures can enable DAX vmemmap
optimization without enabling hugetlb vmemmap optimization. This should
enable architectures like arm64 to enable DAX vmemmap optimization while
they can't enable hugetlb vmemmap optimization. More details of the same
are in patch "mm/vmemmap optimization: Split hugetlb and devdax vmemmap
optimization".
With 64K page size for 16384 pages added (1G) we save 14 pages
With 4K page size for 262144 pages added (1G) we save 4094 pages
With 4K page size for 512 pages added (2M) we save 6 pages
This patch (of 13):
Architectures like powerpc would like to enable transparent huge page pud
support only with radix translation. To support that add
has_transparent_pud_hugepage() helper that architectures can override.

There are two main use cases for mmu notifiers. One is by KVM which uses
mmu_notifier_invalidate_range_start()/end() to manage a software TLB.
The other is to manage hardware TLBs which need to use the
invalidate_range() callback because HW can establish new TLB entries at
any time. Hence using start/end() can lead to memory corruption as these
callbacks happen too soon/late during page unmap.
mmu notifier users should therefore either use the start()/end() callbacks
or the invalidate_range() callbacks. To make this usage clearer rename
the invalidate_range() callback to arch_invalidate_secondary_tlbs() and
update documention.

Patch series "Invalidate secondary IOMMU TLB on permission upgrade", v4.
The main change is to move secondary TLB invalidation mmu notifier
callbacks into the architecture specific TLB flushing functions. This
makes secondary TLB invalidation mostly match CPU invalidation while
still allowing efficient range based invalidations based on the
existing TLB batching code.
This patch (of 5):
The ARM SMMU has a specific command for invalidating the TLB for an entire
ASID. Currently this is used for the IO_PGTABLE API but not for ATS when
called from the MMU notifier.
The current implementation of notifiers does not attempt to invalidate
such a large address range, instead walking each VMA and invalidating each
range individually during mmap removal. However in future SMMU TLB
invalidations are going to be sent as part of the normal flush_tlb_*()
kernel calls. To better deal with that add handling to use TLBI ASID when
invalidating the entire address space.

Patch series "mm: ioremap: Convert architectures to take GENERIC_IOREMAP
way", v8.
Motivation and implementation:
==============================
Currently, many architecutres have't taken the standard GENERIC_IOREMAP
way to implement ioremap_prot(), iounmap(), and ioremap_xx(), but make
these functions specifically under each arch's folder. Those cause many
duplicated code of ioremap() and iounmap().
In this patchset, firstly introduce generic_ioremap_prot() and
generic_iounmap() to extract the generic code for GENERIC_IOREMAP. By
taking GENERIC_IOREMAP method, the generic generic_ioremap_prot(),
generic_iounmap(), and their generic wrapper ioremap_prot(), ioremap() and
iounmap() are all visible and available to arch. Arch needs to provide
wrapper functions to override the generic version if there's arch specific
handling in its corresponding ioremap_prot(), ioremap() or iounmap().
With these changes, duplicated ioremap/iounmap() code uder ARCH-es are
removed, and the equivalent functioality is kept as before.
Background info:
================
1) The converting more architectures to take GENERIC_IOREMAP way is
suggested by Christoph in below discussion:
https://lore.kernel.org/all/Yp7h0Jv6vpgt6xdZ@infradead.org/T/#u
2) In the previous v1 to v3, it's basically further action after arm64
has converted to GENERIC_IOREMAP way in below patchset. It's done by
adding hook ioremap_allowed() and iounmap_allowed() in ARCH to add ARCH
specific handling the middle of ioremap_prot() and iounmap().
[PATCH v5 0/6] arm64: Cleanup ioremap() and support ioremap_prot()
https://lore.kernel.org/all/20220607125027.44946-1-wangkefeng.wang@huawei.com/T/#u
Later, during v3 reviewing, Christophe Leroy suggested to introduce
generic_ioremap_prot() and generic_iounmap() to generic codes, and ARCH
can provide wrapper function ioremap_prot(), ioremap() or iounmap() if
needed. Christophe made a RFC patchset as below to specially demonstrate
his idea. This is what v4 and now v5 is doing.
[RFC PATCH 0/8] mm: ioremap: Convert architectures to take GENERIC_IOREMAP way
https://lore.kernel.org/all/cover.1665568707.git.christophe.leroy@csgroup.eu/T/#u
Testing:
========
In v8, I only applied this patchset onto the latest linus's tree to build
and run on arm64 and s390.
This patch (of 19):
Let's use '#define ioremap_xx' and "#ifdef ioremap_xx" instead.
To remove defined ARCH_HAS_IOREMAP_xx macros in <asm/io.h> of each ARCH,
the ARCH's own ioremap_wc|wt|np definition need be above "#include
<asm-generic/iomap.h>. Otherwise the redefinition error would be seen
during compiling. So the relevant adjustments are made to avoid compiling
error:
loongarch:
- doesn't include <asm-generic/iomap.h>, defining ARCH_HAS_IOREMAP_WC
is redundant, so simply remove it.
m68k:
- selected GENERIC_IOMAP, <asm-generic/iomap.h> has been added in
<asm-generic/io.h>, and <asm/kmap.h> is included above
<asm-generic/iomap.h>, so simply remove ARCH_HAS_IOREMAP_WT defining.
mips:
- move "#include <asm-generic/iomap.h>" below ioremap_wc definition
in <asm/io.h>
powerpc:
- remove "#include <asm-generic/iomap.h>" in <asm/io.h> because it's
duplicated with the one in <asm-generic/io.h>, let's rely on the
latter.
x86:
- selected GENERIC_IOMAP, remove #include <asm-generic/iomap.h> in
the middle of <asm/io.h>. Let's rely on <asm-generic/io.h>.

ACPI TRBE does not have a HID for identification which could create and add
a platform device into the platform bus. Also without a platform device, it
cannot be probed and bound to a platform driver.
This creates a dummy platform device for TRBE after ascertaining that ACPI
provides required interrupts uniformly across all cpus on the system. This
device gets created inside drivers/perf/arm_pmu_acpi.c to accommodate TRBE
being built as a module.

Sanity checking all the GICC tables for same interrupt number, and ensuring
a homogeneous ACPI based machine, could be used for other platform devices
as well. Hence this refactors arm_spe_acpi_register_device() into a common
helper arm_acpi_register_pmu_device().

The code calling ima_free_kexec_buffer runs long after the memblock
allocator has already been torn down, potentially resulting in a use
after free in memblock_isolate_range.
With KASAN or KFENCE, this use after free will result in a BUG
from the idle task, and a subsequent kernel panic.
Switch ima_free_kexec_buffer over to memblock_free_late to avoid
that issue.

regression for the DSI phy.
NXP i.MX has two correctness fixes for the 64-bit chips, dealing with
the imx93 "anatop" module and the CSI interface. On the 32-bit side,
there are functional fixes for RTC, display and SD card intefaces.
Rockchip fixes are for wifi support on certain boards, a eMMC
stability and DT build warnings.
On TI OMAP, a regulator is described in DT to avoid problems with the
ethernet phy initialization.
The code changes include a missing MMIO serialization on OMAP, plus a

Since the NIB is visible by HW, KVM and the (PV) guest it needs to be
in non-secure or secure but shared storage. Return code 6 is used to
indicate to a PV guest that its NIB would be on secure, unshared
storage and therefore the NIB address is invalid.
Unfortunately we have no easy way to check if a page is unshared after
vfio_pin_pages() since it will automatically export an unshared page
if the UV pin shared call did not succeed due to a page being in
unshared state.
Therefore we use the fact that UV pinning it a second time is a nop
but trying to pin an exported page is an error (0x102). If we
encounter this error, we do a vfio unpin and import the page again,
since vfio_pin_pages() exported it.

Check for response codes 0x35 and 0x36 which are asynchronous return codes
indicating a failure of the guest to associate a secret with a queue. Since
there can be no interaction with this queue from the guest (i.e., the vcpus
are out of SIE for hot unplug, the guest is being shut down or an emulated
subsystem reset of the guest is taking place), let's go ahead and re-issue
the ZAPQ to reset and zeroize the queue.

Instead of waiting to verify that a queue is reset in the
vfio_ap_mdev_reset_queue function, let's use a wait queue to check the
the state of the reset. This way, when resetting all of the queues assigned
to a matrix mdev, we don't have to wait for each queue to be reset before
initiating a reset on the next queue to be reset.

The other information contained in the status word is need by the
apq_reset_check function to display a proper message to indicate that the
vfio_ap driver is waiting for the ZAPQ to complete because the queue is

The architecture does not define an upper limit on how long a queue reset
(RAPQ/ZAPQ) can take to complete. In order to ensure both the security
requirements and prevent resource leakage and corruption in the hypervisor,
it is necessary to remove the upper limit (200ms) the vfio_ap driver
currently waits for a reset to complete. This, of course, may result in a
hang which is a less than desirable user experience, but until a firmware
solution is provided, this is a necessary evil.

When a queue is reset, the status response code returned from the reset
operation is stored in the reset_rc field of the vfio_ap_queue structure
representing the queue being reset. This field is later used to decide
whether the queue should be passed through to a guest. If the reset_rc
field is a non-zero value, the queue will be filtered from the list of
queues passed through.
When an adapter is deconfigured, all queues associated with that adapter
are reset. That being the case, it is not necessary to filter those queues;
so, if the status response code returned from a reset operation indicates
the queue is deconfigured, the reset_rc field of the vfio_ap_queue
structure will be set to zero so it will be passed through (i.e., not
filtered).

Instead of returning error -EIO when a ZAPQ fails with response code 05,

The architecture does not specify whether interrupts are disabled as part
of the asynchronous reset or upon return from the PQAP/ZAPQ instruction.
If, however, PQAP/ZAPQ completes with APQSW response code 0 and the
interrupt bit in the status word is also 0, we know the interrupts are
disabled and we can go ahead and clean up the corresponding resources;
otherwise, we must wait until the asynchronous reset has completed.

After a ZAPQ is executed to reset a queue, if the queue is not empty or
interrupts are still enabled, the vfio_ap driver will wait for the reset
operation to complete by repeatedly executing the TAPQ instruction and
checking the 'E' and 'I' bits in the APQSW to verify that the queue is
empty and interrupts are disabled. This is unnecessary because it is
sufficient to check only the response code in the APQSW. If the reset is
still in progress, the response code will be 02; however, if the reset has
completed successfully, the response code will be 00.

Secure execution guest environments require an empty pinblob in all
key generation and unwrap requests. Empty pinblobs are only available
in EP11 API ordinal 6 or higher.
Add an empty pinblob to key generation and unwrap requests, if the AP
secure binding facility is available. In all other cases, stay with
the empty pin tag (no pinblob) and the current API ordinals.
The EP11 API ordinal also needs to be considered when the pkey module
tries to figure out the list of eligible cards for key operations
with protected keys in secure execution environment.
These changes are transparent to userspace but required for running
an secure execution guest with handling key generate and key derive
(e.g. secure key to protected key) correct. Especially using EP11
secure keys with the kernel dm-crypt layer requires this patch.
