Pull kmalloc_obj conversions from Kees Cook: "Another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci" * tag 'kmalloc_obj-v7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: treewide: refresh kmalloc_obj() conversions drm/amd/display: Fix harmless type mismatch in allocation
This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

The Intel UFS 4.0 PCI variant (PCI ID 8086:D335) advertises MCQ support
in its capability register. However, ufshcd_alloc_mcq() also requires an
.op_runtime_config hook to locate the per-queue operation and runtime
(OPR) register blocks, which was not provided by this variant operations
table.
As a result, MCQ initialization fails and ufshcd_add_scsi_host() prints
"MCQ mode is disabled, err=%d\n" before falling back to legacy
single-doorbell (SDB) mode.
Add ufs_intel_mcq_config_resource() to initialize the MCQ configuration
base and add ufs_intel_op_runtime_config() to set up the OPR register
offsets and stride.
Wire both hooks into the variant operations table so MCQ is enabled when
supported by the hardware.

Reliable HS-Gear5 operation on Intel UFS 4.0 controllers requires
configuring PA_INITIAL_ADAPT before changing the power mode. Without
this setting, the link fails to train reliably at Gear5.
Add a pwr_change_notify() hook to configure the adaptation mode before
the power mode transition. Enable this only for UFS 4.0 and later
controllers by checking hba->ufs_version.
Wire the hook into the existing Meteor Lake family variant operations
table (ufs_intel_mtl_hba_vops) instead of introducing a separate table,
since the Intel UFS 4.0 PCI variant (PCI ID 8086:D335) already uses this
vops table and the hook is internally gated on UFS version >= 4.0.
Use PA_INITIAL_ADAPT when the negotiated TX power mode is FAST_MODE or
FASTAUTO_MODE. Otherwise, reset the adaptation mode to PA_NO_ADAPT,
which is the default setting.

The current devfreq downdifferential threshold of 5% causes overly aggressive frequency downscaling, leading to performance degradation sometimes during sequential read workloads. Update the UFS devfreq downdifferential threshold to 65. This widens the hysteresis window and prevents overly aggressive downscaling, ensuring that frequency is maintained for loads above 5% and scaling down occurs only when utilization falls below this level, while scale-up still triggers above the 70% threshold.

The link startup mode (HS LSS - high-speed link startup, or LS LSS - low-speed link startup) is decided in the boot stage based on the bootconfig GPIO. This selection is carried forward through the secondary stage bootloaders and finally to HLOS via the spare configuration register (REG_UFS_DEBUG_SPARE_CFG). On Qualcomm UFS controller v6.2 and later, bit 31 in the spare configuration register indicates the high-speed link startup mode selection, as per the Hardware Programming Guide (HPG). The spare register value is read during host driver initialization but gets cleared after UFS reset. Preserve the spare register value during initialization and restore it during link startup to maintain the bootloader-configured link startup mode.
