For configurations that have the kconfig option NUMA_KEEP_MEMINFO
disabled, numa_fill_memblks() only returns with NUMA_NO_MEMBLK (-1).
SRAT lookup fails then because an existing SRAT memory range cannot be
found for a CFMWS address range. This causes the addition of a
duplicate numa_memblk with a different node id and a subsequent page
fault and kernel crash during boot.
Fix this by making numa_fill_memblks() always available regardless of
NUMA_KEEP_MEMINFO.
As Dan suggested, the fix is implemented to remove numa_fill_memblks()
from sparsemem.h and alos using __weak for the function.
Note that the issue was initially introduced with [1]. But since
phys_to_target_node() was originally used that returned the valid node
0, an additional numa_memblk was not added. Though, the node id was
wrong too, a message is seen then in the logs:

iommu_dma_map_page() allocates swiotlb memory as a bounce buffer when an
untrusted device wants to map only part of the memory in an granule. The
goal is to disallow the untrusted device having DMA access to unrelated
kernel data that may be sharing the granule. To meet this goal, the
bounce buffer itself is zeroed, and any additional swiotlb memory up to
alloc_size after the bounce buffer end (i.e., "post-padding") is also
zeroed.
However, as of commit 901c7280ca0d ("Reinstate some of "swiotlb: rework
"fix info leak with DMA_FROM_DEVICE"""), swiotlb_tbl_map_single() always
initializes the contents of the bounce buffer to the original memory.
Zeroing the bounce buffer is redundant and probably wrong per the
discussion in that commit. Only the post-padding needs to be zeroed.
Also, when the DMA min_align_mask is non-zero, the allocated bounce
buffer space may not start on a granule boundary. The swiotlb memory
from the granule boundary to the start of the allocated bounce buffer
might belong to some unrelated bounce buffer. So as described in the
"second issue" in [1], it can't be zeroed to protect against untrusted
devices. But as of commit af133562d5af ("swiotlb: extend buffer
pre-padding to alloc_align_mask if necessary"), swiotlb_tbl_map_single()
allocates pre-padding slots when necessary to meet min_align_mask
requirements, making it possible to zero the pre-padding area as well.
Finally, iommu_dma_map_page() uses the swiotlb for untrusted devices
and also for certain kmalloc() memory. Current code does the zeroing
for both cases, but it is needed only for the untrusted device case.
Fix all of this by updating iommu_dma_map_page() to zero both the
pre-padding and post-padding areas, but not the actual bounce buffer.
Do this only in the case where the bounce buffer is used because
of an untrusted device.

Currently swiotlb_tbl_map_single() takes alloc_align_mask and
alloc_size arguments to specify an swiotlb allocation that is larger
than mapping_size. This larger allocation is used solely by
iommu_dma_map_single() to handle untrusted devices that should not have
DMA visibility to memory pages that are partially used for unrelated
kernel data.
Having two arguments to specify the allocation is redundant. While
alloc_align_mask naturally specifies the alignment of the starting
address of the allocation, it can also implicitly specify the size
by rounding up the mapping_size to that alignment.
Additionally, the current approach has an edge case bug.
iommu_dma_map_page() already does the rounding up to compute the
alloc_size argument. But swiotlb_tbl_map_single() then calculates the
alignment offset based on the DMA min_align_mask, and adds that offset to
alloc_size. If the offset is non-zero, the addition may result in a value
that is larger than the max the swiotlb can allocate. If the rounding up
is done _after_ the alignment offset is added to the mapping_size (and
the original mapping_size conforms to the value returned by
swiotlb_max_mapping_size), then the max that the swiotlb can allocate
will not be exceeded.
In view of these issues, simplify the swiotlb_tbl_map_single() interface
by removing the alloc_size argument. Most call sites pass the same value
for mapping_size and alloc_size, and they pass alloc_align_mask as zero.
Just remove the redundant argument from these callers, as they will see
no functional change. For iommu_dma_map_page() also remove the alloc_size
argument, and have swiotlb_tbl_map_single() compute the alloc_size by
rounding up mapping_size after adding the offset based on min_align_mask.
This has the side effect of fixing the edge case bug but with no other
functional change.
Also add a sanity test on the alloc_align_mask. While IOMMU code
currently ensures the granule is not larger than PAGE_SIZE, if that
guarantee were to be removed in the future, the downstream effect on the
swiotlb might go unnoticed until strange allocation failures occurred.
Tested on an ARM64 system with 16K page size and some kernel test-only
hackery to allow modifying the DMA min_align_mask and the granule size
that becomes the alloc_align_mask. Tested these combinations with a
variety of original memory addresses and sizes, including those that
reproduce the edge case bug:
* 4K granule and 0 min_align_mask
* 4K granule and 0xFFF min_align_mask (4K - 1)
* 16K granule and 0xFFF min_align_mask
* 64K granule and 0xFFF min_align_mask
* 64K granule and 0x3FFF min_align_mask (16K - 1)
With the changes, all combinations pass.

Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide
direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO
bus the switch listens on. The PHY muxing feature makes use of this.
This is problematic as the PHY may be attached before the switch is
initialised, in which case, the PHY will fail to be attached.
Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration
of switch MDIO bus"), we can describe the switch PHYs on the MDIO bus of
the switch on the device tree. Extend the check to detect PHY muxing when
the PHY is defined on the MDIO bus of the switch on the device tree.
When the PHY is described this way, the switch will be initialised first,
then the switch MDIO bus will be registered. Only after these steps, the
PHY will be attached.

RISC-V SoC Kconfig Updates for v6.10
A few different bits of SoC-related Kconfig work. The first part of

users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away
from the k230 that is able to be used in a "common" kernel.
The other thing here is the removal of most of the SOC_VENDOR options,
with their ARCH_VENDOR equivalents that've been waiting in the wings for
1 year+ now made visible. Due a lapse on my part when originally adding
the ARCH_VENDOR stuff, the Microchip transition isn't complete - the

The driver's I/O path is updated to support 32 byte CDBs.
Changes to accommodate 32 byte CDBs include:
- Updating various size fields to allow for the larger 32 byte CDB.
- Starting the FCP command payload at an earlier offset in WQE submission
to fit the 32 byte CDB.
- Redefining relevant structs to __le32/__be32 data types for proper cpu
endianness macro usage.

In attempt to reduce the amount of unnecessary phba->hbalock acquisitions
in the lpfc driver, change hba_flag into an unsigned long bitmask and use
clear_bit/test_bit bitwise atomic APIs instead of reliance on phba->hbalock
for synchronization.

Instead of using the generic object wide phba->hbalock, an explicit lock
should be used to synchronize mutations to the phba->active_rrq_list.
Update all accesses to the phba->active_rrq_list with a new
phba->rrq_list_lock.

Device recovery logic is skipped when the RSCN processing flag is set.
However during rmmod, the flag is not cleared leading to unnecessary delays
in waiting for completions on a link that is being offlined.
Move clearing of the RSCN deferred flag to a refactored routine when called
from device recovery, and set the IA flag when issuing an abort during
unload.

A struct scsi_cmnd already contains T10 DIF protection type information in
prot_type. So, instead of manually checking a CDBs' RD/WRPROTECT fields
with (byte[1] >> 5) utilize scsi_get_prot_type().

For diagnostic purposes, it is convenient to automatically log unexpected
CT MIB events without the need to set lpfc_log_verbose flags. So, change
lpfc_ct_handle_mibreq's logging level from KERN_INFO to KERN_WARNING.

Commit be50f538e9a5 ("target: remove g_device_list") made 'g_device_list'
local as 'device_list' but also removed the last use of it, the code that
added the device to it.
Build tested only.

Hi Martin, James & Alim,
This series adds support to the ufs-exynos driver for Tensor gs101
found in Pixel 6. It was send previously in [1] and [2] but included
the other clock, phy and DTS parts. This series has been split into
just the ufs-exynos part to hopefully make things easier.
With this series, plus the phy, clock and dts changes UFS is
functional upstream for Pixel 6. The SKhynix HN8T05BZGKX015 can be
enumerated, partitions mounted etc.
The series is split into some prepatory patches for ufs-exynos and a
final patch that adds the gs101 support.
Note the sysreg clock has been moved to ufs node as fine grained clock
control around the syscon sysreg register accesses doesn't result in
functional UFS.
regards,
Peter

Add a dedicated compatible and drv_data with associated hooks for gs101 SoC
found on Pixel 6.
Note we make use of the previously added EXYNOS_UFS_OPT_UFSPR_SECURE
option, to skip initialisation of UFSPR registers as these are only
accessible via SMC call.
EXYNOS_UFS_OPT_TIMER_TICK_SELECT option is also set to select tick
source. This has been done so as not to effect any existing platforms.
DBG_OPTION_SUITE on gs101 has different address offsets to other SoCs so
these register offsets now come from uic_attr struct.

This allows these registers to be at different offsets or not exist at all
on some SoCs variants.

Platforms such as Tensor gs101 the pclk frequency is 267Mhz. Increase
PCLK_AVAIL_MAX so we don't fail the frequency check.

This option is intended to be set for SoCs that have HCI_V2P1_CTRL register
and can select their tick source via IA_TICK_SEL bit.
Source clock selection for timer tick
0x0 = Bus clock (aclk)
0x1 = Function clock (mclk)
