When both ACPI and OF are disabled, the dev_vdata variable is unused:
drivers/crypto/ccp/sp-platform.c:33:34: error: unused variable 'dev_vdata' [-Werror,-Wunused-const-variable]
This is not a useful configuration, and there is not much point in saving
a few bytes when only one of the two is enabled, so just remove all
these ifdef checks and rely on of_match_node() and acpi_match_device()
returning NULL when these subsystems are disabled.

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally.
Use the `__struct_group()` helper to separate the flexible array
from the rest of the members in flexible `struct qat_alg_buf_list`,
through tagged `struct qat_alg_buf_list_hdr`, and avoid embedding the
flexible-array member in the middle of `struct qat_alg_fixed_buf_list`.
Also, use `container_of()` whenever we need to retrieve a pointer to
the flexible structure.
So, with these changes, fix the following warnings:

There are considerations to drop platform_driver_probe() as a concept
that isn't relevant any more today. It comes with an added complexity
that makes many users hold it wrong. (E.g. this driver should have mark
the driver struct with __refdata.)
Convert the driver to the more usual module_platform_driver().
This fixes a W=1 build warning:
WARNING: modpost: drivers/char/hw_random/mxc-rnga: section mismatch in reference: mxc_rnga_driver+0x10 (section: .data) -> mxc_rnga_remove (section: .exit.text)

Per filesystems/sysfs.rst, show() should only use sysfs_emit()
or sysfs_emit_at() when formatting the value to be returned to user space.
coccinelle complains that there are still a couple of functions that use

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally. So, we are deprecating flexible-array
members in the middle of another structure.
There is currently an object (`header`) in `struct nx842_crypto_ctx`
that contains a flexible structure (`struct nx842_crypto_header`):
struct nx842_crypto_ctx {
...
struct nx842_crypto_header header;
struct nx842_crypto_header_group group[NX842_CRYPTO_GROUP_MAX];
...
};
So, in order to avoid ending up with a flexible-array member in the
middle of another struct, we use the `struct_group_tagged()` helper to
separate the flexible array from the rest of the members in the flexible
structure:
struct nx842_crypto_header {
struct_group_tagged(nx842_crypto_header_hdr, hdr,
... the rest of the members
);
struct nx842_crypto_header_group group[];
} __packed;
With the change described above, we can now declare an object of the
type of the tagged struct, without embedding the flexible array in the
middle of another struct:
struct nx842_crypto_ctx {
...
struct nx842_crypto_header_hdr header;
struct nx842_crypto_header_group group[NX842_CRYPTO_GROUP_MAX];
...
} __packed;
We also use `container_of()` whenever we need to retrieve a pointer to
the flexible structure, through which we can access the flexible
array if needed.
So, with these changes, fix the following warning:
In file included from drivers/crypto/nx/nx-842.c:55:
drivers/crypto/nx/nx-842.h:174:36: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Currently, the wq_stats output also includes the global stats, while
the individual global stats are also available as separate debugfs
files. Since these are all read-only, there's really no reason to
have them as separate files, especially since we already display them
as global stats in the wq_stats. It makes more sense to just add a
separate global_stats file to display those, and remove them from the
wq_stats, as well as removing the individual stats files.

Add logic to implement the interface for live migration defined in
qat/qat_mig_dev.h. This is specific for QAT GEN4 Virtual Functions
(VFs).
This introduces a migration data manager which is used to handle the
device state during migration. The manager ensures that the device state
is stored in a format that can be restored in the destination node.
The VF state is organized into a hierarchical structure that includes a
preamble, a general state section, a MISC bar section and an ETR bar
section. The latter contains the state of the 4 ring pairs contained on
a VF. Here is a graphical representation of the state:
preamble | general state section | leaf state
| MISC bar state section| leaf state
| ETR bar state section | bank0 state section | leaf state
| bank1 state section | leaf state
| bank2 state section | leaf state
| bank3 state section | leaf state
In addition to the implementation of the qat_migdev_ops interface and
the state manager framework, add a mutex in pfvf to avoid pf2vf messages
during migration.

Clearing BSS should only be done once, at the very beginning.
efi_pe_entry() is the entrypoint from the firmware, which may not clear
BSS and so it is done explicitly. However, efi_pe_entry() is also used
as an entrypoint by the mixed mode startup code, in which case BSS will
already have been cleared, and doing it again at this point will corrupt
global variables holding the firmware's GDT/IDT and segment selectors.
So make the memset() conditional on whether the EFI stub is running in
native mode.

Pull more SCSI updates from James Bottomley:
"The vfs has long had a write lifetime hint mechanism that gives the
expected longevity on storage of the data being written. f2fs was the
original consumer of this and used the hint for flash data placement

lifetimes in the same erase block).
More recently the SCSI based UFS (Universal Flash Storage) drivers
have wanted to take advantage of this as well, for the same reasons as
f2fs, necessitating plumbing the write hints through the block layer
and then adding it to the SCSI core.
The vfs write_hints already taken plumbs this as far as block and this
completes the SCSI core enabling based on a recently agreed reuse of
the old write command group number. The additions to the scsi_debug

higher address
Following warning is sometimes observed while booting my servers:
[ 3.594838] DMA: preallocated 4096 KiB GFP_KERNEL pool for atomic allocations
[ 3.602918] swapper/0: page allocation failure: order:10, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0-1
...
[ 3.851862] DMA: preallocated 1024 KiB GFP_KERNEL|GFP_DMA pool for atomic allocation
If 'nokaslr' boot option is set, the warning always happens.
On x86, ZONE_DMA is small zone at the first 16MB of physical address
space. When this problem happens, most of that space seems to be used by
decompressed kernel. Thereby, there is not enough space at DMA_ZONE to
meet the request of DMA pool allocation.
The commit 2f77465b05b1 ("x86/efistub: Avoid placing the kernel below
LOAD_PHYSICAL_ADDR") tried to fix this problem by introducing lower
bound of allocation.
But the fix is not complete.
efi_random_alloc() allocates pages by following steps.
1. Count total available slots ('total_slots')
2. Select a slot ('target_slot') to allocate randomly
3. Calculate a starting address ('target') to be included target_slot
4. Allocate pages, which starting address is 'target'
In step 1, 'alloc_min' is used to offset the starting address of memory
chunk. But in step 3 'alloc_min' is not considered at all. As the
result, 'target' can be miscalculated and become lower than 'alloc_min'.
When KASLR is disabled, 'target_slot' is always 0 and the problem
happens everytime if the EFI memory map of the system meets the
condition.
Fix this problem by calculating 'target' considering 'alloc_min'.

If nr_cpus < nr_iaa, the calculated cpus_per_iaa will be 0, which
causes a divide-by-0 in rebalance_wq_table().
Make sure cpus_per_iaa is 1 in that case, and also in the nr_iaa == 0
case, even though cpus_per_iaa is never used if nr_iaa == 0, for
paranoia.
