When MTD or MTD_CFI_GEOMETRY is disabled, the spi-intel driver
fails to build, as it includes the shared CFI header:
include/linux/mtd/cfi.h:62:2: error: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. [-Werror=cpp]
62 | #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work.
linux/mtd/spi-nor.h does not actually need to include cfi.h, so
remove the inclusion here to fix the warning. This uncovers a
missing #include in spi-nor/core.c so add that there to
prevent a different build issue.

fsverity_operations::write_merkle_tree_block is passed the index of the
block to write and the log base 2 of the block size. However, all
implementations of it use these parameters only to calculate the

Therefore, make ->write_merkle_tree_block take 'pos' and 'size'

Add advanced RPMB support in ufs_bsg:
1. According to the UFS specification, only one RPMB operation can be
performed at any time. We can ensure this by using reserved slot and
its dev_cmd sync operation protection mechanism.
2. For Advanced RPMB, RPMB metadata is packaged in an EHS (Extra Header
Segment) of a command UPIU, and the corresponding reply EHS (from the
device) should also be returned to the user space. bsg_job->request
and bsg_job->reply allow us to pass and return EHS from/back to
userspace.
Compared to normal/legacy RPMB, the advantages of advanced RPMB are:
1. The data length in the Advanced RPMB data read/write command can be
larger than 4KB. For the legacy RPMB, the data length in a single RPMB
data transfer is 256 bytes.
2. All of the advanced RPMB operations will be a single command. For
legacy RPMB, take the read write-counter value as an example, you need
two commands (first SECURITY PROTOCOL OUT, then second SECURITY
PROTOCOL IN).

There are several different drivers that accesses the Intel TCC
(thermal control circuitry) MSRs, and each of them has its own
implementation for the same functionalities, e.g. getting the current
temperature, getting the tj_max, and getting/setting the tj_max offset.
Introduce a library to unify the code for Intel CPU TCC MSR access.
At the same time, ensure the temperature is got based on the updated
tjmax value because tjmax can be changed at runtime for cases like
the Intel SST-PP (Intel Speed Select Technology - Performance Profile)

The coding style where calling this interface is inconsistent with other

is like:
#ifdefine CONFIG_SCSI_SAS_ATA
void sas_ata_task_abort(struct sas_task *task);
#else
static inline void sas_ata_task_abort(struct sas_task *task)
{
}
#endif
And the callers does not have to do things like "#ifdefine CONFIG_SCSI_SAS_ATA"
and may call the interface directly. So follow the standard style here.

kmap_atomic() is used to create short-lived mappings of pages that may
not be accessible via the kernel direct map. This is only needed on
32-bit architectures that implement CONFIG_HIGHMEM, but it can be used
on 64-bit other architectures too, where the returned mapping is simply
the kernel direct address of the page.
However, kmap_atomic() does not support migration on CONFIG_HIGHMEM
configurations, due to the use of per-CPU kmap slots, and so it disables
preemption on all architectures, not just the 32-bit ones. This implies
that all scatterwalk based crypto routines essentially execute with
preemption disabled all the time, which is less than ideal.
So let's switch scatterwalk_map/_unmap and the shash/ahash routines to
kmap_local() instead, which serves a similar purpose, but without the
resulting impact on preemption on architectures that have no need for
CONFIG_HIGHMEM.

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
since commit 994b7ac169 ("arm64: remove special treatment for the
link order of head.o").
The issue is that the type of .notes section, which contains the BuildID,
changed from NOTES to PROGBITS.
Ard Biesheuvel figured out that whichever object gets linked first gets
to decide the type of a section. The PROGBITS type is the result of the
compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.
While Ard provided a fix for arm64, I want to fix this globally because
the same issue is happening on riscv since commit 2348e6bf44 ("riscv:
remove special treatment for the link order of head.o"). This problem
will happen in general for other architectures if they start to drop

Jiri Slaby reported regression of bind() with a simple repro. [0]
The repro creates a TIME_WAIT socket and tries to bind() a new socket
with the same local address and port. Before commit 28044fc1d4 ("net:
Add a bhash2 table hashed by port and address"), the bind() failed with
-EADDRINUSE, but now it succeeds.
The cited commit should have put TIME_WAIT sockets into bhash2; otherwise,
inet_bhash2_conflict() misses TIME_WAIT sockets when validating bind()
requests if the address is not a wildcard one.
The straight option is to move sk_bind2_node from struct sock to struct
sock_common to add twsk to bhash2 as implemented as RFC. [1] However, the
binary layout change in the struct sock could affect performances moving
hot fields on different cachelines.
To avoid that, we add another TIME_WAIT list in inet_bind2_bucket and check
it while validating bind().

Pull io_uring fixes from Jens Axboe:
- Two fixes for mutex grabbing when the task state is != TASK_RUNNING
(me)
- Check for invalid opcode in io_uring_register() a bit earlier, to
avoid going through the quiesce machinery just to return -EINVAL
later in the process (me)
- Fix for the uapi io_uring header, skipping including time_types.h
when necessary (Stefan)

Allow architectures to opt out of the generic hardware enabling logic,
and opt out on both s390 and PPC, which don't need to manually enable
virtualization as it's always on (when available).
In addition to letting s390 and PPC drop a bit of dead code, this will
hopefully also allow ARM to clean up its related code, e.g. ARM has its
own per-CPU flag to track which CPUs have enable hardware due to the
need to keep hardware enabled indefinitely when pKVM is enabled.

The CPU STARTING section doesn't allow callbacks to fail. Move KVM's
hotplug callback to ONLINE section so that it can abort onlining a CPU in
certain cases to avoid potentially breaking VMs running on existing CPUs.
For example, when KVM fails to enable hardware virtualization on the
hotplugged CPU.
Place KVM's hotplug state before CPUHP_AP_SCHED_WAIT_EMPTY as it ensures
when offlining a CPU, all user tasks and non-pinned kernel tasks have left
the CPU, i.e. there cannot be a vCPU task around. So, it is safe for KVM's
CPU offline callback to disable hardware virtualization at that point.
Likewise, KVM's online callback can enable hardware virtualization before
any vCPU task gets a chance to run on hotplugged CPUs.
Drop kvm_x86_check_processor_compatibility()'s WARN that IRQs are
disabled, as the ONLINE section runs with IRQs disabled. The WARN wasn't
intended to be a requirement, e.g. disabling preemption is sufficient,
the IRQ thing was purely an aggressive sanity check since the helper was
only ever invoked via SMP function call.
Rename KVM's CPU hotplug callbacks accordingly.

Define pr_fmt using KBUILD_MODNAME for all KVM x86 code so that printks
use consistent formatting across common x86, Intel, and AMD code. In
addition to providing consistent print formatting, using KBUILD_MODNAME,
e.g. kvm_amd and kvm_intel, allows referencing SVM and VMX (and SEV and
SGX and ...) as technologies without generating weird messages, and
without causing naming conflicts with other kernel code, e.g. "SEV: ",
"tdx: ", "sgx: " etc.. are all used by the kernel for non-KVM subsystems.
Opportunistically move away from printk() for prints that need to be
modified anyways, e.g. to drop a manual "kvm: " prefix.
Opportunistically convert a few SGX WARNs that are similarly modified to
WARN_ONCE; in the very unlikely event that the WARNs fire, odds are good
that they would fire repeatedly and spam the kernel log without providing
unique information in each print.
Note, defining pr_fmt yields undesirable results for code that uses KVM's
printk wrappers, e.g. vcpu_unimpl(). But, that's a pre-existing problem
as SVM/kvm_amd already defines a pr_fmt, and thankfully use of KVM's
wrappers is relatively limited in KVM x86 code.

For a number of historical reasons, the KVM/arm64 hotplug setup is pretty
complicated, and we have two extra CPUHP notifiers for vGIC and timers.
It looks pretty pointless, and gets in the way of further changes.
So let's just expose some helpers that can be called from the core
CPUHP callback, and get rid of everything else.
This gives us the opportunity to drop a useless notifier entry,
as well as tidy-up the timer enable/disable, which was a bit odd.

Many of the structs recently added to track field info for linked-list
head are useful as-is for rbtree root. So let's do a mechanical renaming
of list_head-related types and fields:
include/linux/bpf.h:
struct btf_field_list_head -> struct btf_field_graph_root
list_head -> graph_root in struct btf_field union
kernel/bpf/btf.c:
list_head -> graph_root in struct btf_field_info
This is a nonfunctional change, functionality to actually use these
fields for rbtree will be added in further patches.

Fix SRIOV VST mode behavior to insert cvlan when a guest tag is already
present in the frame. Previous VST mode behavior was to drop packets or
override existing tag, depending on the device version.
In this patch we fix this behavior by correctly building the HW steering
rule with a push vlan action, or for older devices we ask the FW to stack
the vlan when a vlan is already present.
