Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX,
to allow userspace to provide information about the support of
TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API.
GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>,
<ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>,
<Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and
<Instruction.WRMSR>. They must be supported by VMM to support TDX guests.
For GetTdVmCallInfo
- When leaf (r12) to enumerate TDVMCALL functionality is set to 0,
successful execution indicates all GHCI base TDVMCALLs listed above are
supported.
Update the KVM TDX document with the set of the GHCI base APIs.
- When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it
indicates the TDX guest is querying the supported TDVMCALLs beyond
the GHCI base TDVMCALLs.
Exit to userspace to let userspace set the TDVMCALL sub-function bit(s)
accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s)
supported by itself when the TDVMCALLs don't need support from userspace
after returning from userspace and before entering guest. Currently, no
such TDVMCALLs implemented, KVM just sets the values returned from
userspace.

Handle TDVMCALL for GetQuote to generate a TD-Quote.
GetQuote is a doorbell-like interface used by TDX guests to request VMM
to generate a TD-Quote signed by a service hosting TD-Quoting Enclave
operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in
a shared-memory area as parameter. Host VMM can access it and queue the
operation for a service hosting TD-Quoting enclave. When completed, the
Quote is returned via the same shared-memory area.
KVM only checks the GPA from the TDX guest has the shared-bit set and drops
the shared-bit before exiting to userspace to avoid bleeding the shared-bit
into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU)
and userspace VMM queues the operation asynchronously. KVM sets the return
code according to the 'ret' field set by userspace to notify the TDX guest
whether the request has been queued successfully or not. When the request
has been queued successfully, the TDX guest can poll the status field in
the shared-memory area to check whether the Quote generation is completed
or not. When completed, the generated Quote is returned via the same
buffer.
Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is
required to handle the KVM exit reason as the initial support for TDX,
by reentering KVM to ensure that the TDVMCALL is complete. While at it,
add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

Commit under fixes switched to uAPI generation from the YAML
spec. A number of custom defines were left behind, mostly
for commands very hard to express in YAML spec.
Among what was left behind was the name and version of
the generic netlink family. Problem is that the codegen
always outputs those values so we ended up with a duplicated,
differently named set of defines.
Provide naming info in YAML and remove the incorrect defines.

Dual and quad capable chips natively support dual and quad I/O variants
at up to 104MHz (1-2-2 and 1-4-4 operations). Reaching the maximum speed
of 166MHz is theoretically possible (while still unsupported in the
field) by adding a few more dummy cycles. Let's be accurate and clearly
state this limit.
Setting a maximum frequency implies adding the frequency parameter to
the macro, which is done using a variadic argument to avoid impacting
all the other drivers which already make use of this macro.

The idea behind this patch was to always let a "master" mtd device
available to anchor runtime PM. Historically, there was no mtd device
representing the whole storage as soon as partitions were coming into
play. The introduction of CONFIG_MTD_PARTITIONED_MASTER allowed to keep
this "master" device, but was not enabled by default to avoid breaking
existing users (otherwise the mtd device numbering would be totally
messed up with an off by 1, at least).
The approach of adding an mtd_master class on top of partitioned mtd
devices is breaking the mtd core in many creative ways, so better think
again this approach and revert the faulty changes for now.
This reverts commit 0aa7b390fc.

In vcc_sendmsg(), we account skb->truesize to sk->sk_wmem_alloc by
atm_account_tx().
It is expected to be reverted by atm_pop_raw() later called by
vcc->dev->ops->send(vcc, skb).
However, vcc_sendmsg() misses the same revert when copy_from_iter_full()
fails, and then we will leak a socket.
Let's factorise the revert part as atm_return_tx() and call it in
the failure path.
Note that the corresponding sk_wmem_alloc operation can be found in
alloc_tx() as of the blamed commit.

In the resctrl subsystem's Sub-NUMA Cluster (SNC) mode, the rdt_mon_domain
structure representing a NUMA node relies on the cacheinfo interface
(rdt_mon_domain::ci) to store L3 cache information (e.g., shared_cpu_map)
for monitoring. The L3 cache information of a SNC NUMA node determines
which domains are summed for the "top level" L3-scoped events.
rdt_mon_domain::ci is initialized using the first online CPU of a NUMA
node. When this CPU goes offline, its shared_cpu_map is cleared to contain
only the offline CPU itself. Subsequently, attempting to read counters
via smp_call_on_cpu(offline_cpu) fails (and error ignored), returning
zero values for "top-level events" without any error indication.
Replace the cacheinfo references in struct rdt_mon_domain and struct
rmid_read with the cacheinfo ID (a unique identifier for the L3 cache).
rdt_domain_hdr::cpu_mask contains the online CPUs associated with that
domain. When reading "top-level events", select a CPU from
rdt_domain_hdr::cpu_mask and utilize its L3 shared_cpu_map to determine
valid CPUs for reading RMID counter via the MSR interface.
Considering all CPUs associated with the L3 cache improves the chances
of picking a housekeeping CPU on which the counter reading work can be
queued, avoiding an unnecessary IPI.

Pull x86 fixes from Dave Hansen:
"This is a pretty scattered set of fixes. The majority of them are
further fixups around the recent ITS mitigations.
The rest don't really have a coherent story:
- Some flavors of Xen PV guests don't support large pages, but the
set_memory.c code assumes all CPUs support them.
Avoid problems with a quick CPU feature check.
- The TDX code has some wrappers to help retry calls to the TDX
module. They use function pointers to assembly functions and the
compiler usually generates direct CALLs. But some new compilers,
plus -Os turned them in to indirect CALLs and the assembly code was
not annotated for indirect calls.
Force inlining of the helper to fix it up.
- Last, a FRED issue showed up when single-stepping. It's fine when
using an external debugger, but was getting stuck returning from a
SIGTRAP handler otherwise.
Clear the FRED 'swevent' bit to ensure that forward progress is
made"

Merge cpuidle updates for 6.16-rc2:
- Update data types of variables passed as arguments to
mwait_idle_with_hints() to match the function definition
after recent changes (Uros Bizjak).
- Eliminate mwait_play_dead_cpuid_hint() again after reverting its
elimination during the merge window due to a problem with handling
"dead" SMT siblings, but this time prevent leaving them in C1 after
initialization by taking them online and back offline when a proper
cpuidle driver for the platform has been registered (Rafael Wysocki).

Similarly to 26064d3e2b ("block: fix adding folio to bio"), if
we attempt to add a folio that is larger than 4GB, we'll silently
truncate the offset and len. Widen the parameters to size_t, assert
that the length is less than 4GB and set the first page that contains
the interesting data rather than the first page of the folio.

Commit 698de82278 ("crypto: testmgr - make it easier to enable the
full set of tests") removed support for building kernels that run only
the "fast" set of crypto self-tests by default. This assumed that
nearly everyone actually wanted the full set of tests, *if* they had
already chosen to enable the tests at all.
Unfortunately, it turns out that both Debian and Fedora intentionally
have the crypto self-tests enabled in their production kernels. And for
production kernels we do need to keep the testing time down, which
implies just running the "fast" tests, not the full set of tests.
For Fedora, a reason for enabling the tests in production is that they
are being (mis)used to meet the FIPS 140-3 pre-operational testing
requirement.
However, the other reason for enabling the tests in production, which
applies to both distros, is that they provide some value in protecting
users from buggy drivers. Unfortunately, the crypto/ subsystem has many
buggy and untested drivers for off-CPU hardware accelerators on rare
platforms. These broken drivers get shipped to users, and there have
been multiple examples of the tests preventing these buggy drivers from
being used. So effectively, the tests are being relied on in production
kernels. I think this is kind of crazy (untested drivers should just
not be enabled at all), but that seems to be how things work currently.
Thus, reintroduce a kconfig option that controls the level of testing.
Call it CRYPTO_SELFTESTS_FULL instead of the original name
CRYPTO_MANAGER_EXTRA_TESTS, which was slightly misleading.
Moreover, given the "production kernel" use case, make CRYPTO_SELFTESTS
depend on EXPERT instead of DEBUG_KERNEL.
I also haven't reinstated all the #ifdefs in crypto/testmgr.c. Instead,
just rely on the compiler to optimize out unused code.

Nested file systems, that is those which invoke call_mmap() within their
own f_op->mmap() handlers, may encounter underlying file systems which
provide the f_op->mmap_prepare() hook introduced by commit c84bf6dd2b
("mm: introduce new .mmap_prepare() file callback").
We have a chicken-and-egg scenario here - until all file systems are
converted to using .mmap_prepare(), we cannot convert these nested
handlers, as we can't call f_op->mmap from an .mmap_prepare() hook.
So we have to do it the other way round - invoke the .mmap_prepare() hook
from an .mmap() one.
in order to do so, we need to convert VMA state into a struct vm_area_desc
descriptor, invoking the underlying file system's f_op->mmap_prepare()
callback passing a pointer to this, and then setting VMA state accordingly
and safely.
This patch achieves this via the compat_vma_mmap_prepare() function, which
we invoke from call_mmap() if f_op->mmap_prepare() is specified in the
passed in file pointer.
We place the fundamental logic into mm/vma.h where VMA manipulation
belongs. We also update the VMA userland tests to accommodate the
changes.
The compat_vma_mmap_prepare() function and its associated machinery is
temporary, and will be removed once the conversion of file systems is
complete.
We carefully place this code so it can be used with CONFIG_MMU and also
with cutting edge nommu silicon.

The permission management of the pages allocated from execmem for ITS
mitigation is now completely contained in arch/x86/kernel/alternatives.c

sk->sk_prot->sock_is_readable is a valid function pointer when sk resides
in a sockmap. After the last sk_psock_put() (which usually happens when
socket is removed from sockmap), sk->sk_prot gets restored and
sk->sk_prot->sock_is_readable becomes NULL.
This makes sk_is_readable() racy, if the value of sk->sk_prot is reloaded
after the initial check. Which in turn may lead to a null pointer
dereference.
Ensure the function pointer does not turn NULL after the check.

On at least an ASRock 990FX Extreme 4 with a VIA VT6330, the devices
have not yet been enabled by the first time ata_acpi_cbl_80wire() is
called. This means that the ata_for_each_dev loop is never entered,
and a 40 wire cable is assumed.
The VIA controller on this board does not report the cable in the PCI
config space, thus having to fall back to ACPI even though no SATA
bridge is present.
The _GTM values are correctly reported by the firmware through ACPI,
which has already set up faster transfer modes, but due to the above
the controller is forced down to a maximum of UDMA/33.
Resolve this by modifying ata_acpi_cbl_80wire() to directly return the
cable type. First, an unknown cable is assumed which preserves the mode
set by the firmware, and then on subsequent calls when the devices have
been enabled, an 80 wire cable is correctly detected.
Since the function now directly returns the cable type, it is renamed
to ata_acpi_cbl_pata_type().

The renaming to the timer_*() namespace was delayed due massive conflicts
against Linux-next. Now that everything is upstream finish the conversion.

- Fix regression of waiting a long time on updating trace event filters
When the faultable trace points were added, it needed task trace RCU
synchronization. This was added to the tracepoint_synchronize_unregister()
function. The filter logic always called this function whenever it
updated the trace event filters before freeing the old filters.
This increased the time of "trace-cmd record" from taking 13 seconds
to running over 2 minutes to complete.
Move the freeing of the filters to call_rcu*() logic, which brings the
time back down to 13 seconds.
- Fix ring_buffer_subbuf_order_set() error path lock protection
The error path of the ring_buffer_subbuf_order_set() released the
mutex too early and allowed subsequent accesses to setting the
subbuffer size to corrupt the data and cause a bug.
By moving the mutex locking to the end of the error path, it prevents
the reentrant access to the critical data and also allows the function
to convert the taking of the mutex over to the guard() logic.
- Remove unused power management clock events
The clock events were added in 2010 for power management. In 2011
arm used them. In 2013 the code they were used in was removed.
These events have been wasting memory since then.
- Fix sparse warnings
There was a few places that sparse warned about trace_events_filter.c
where file->filter was referenced directly, but it is annotated with
an __rcu tag. Use the helper functions and fix them up to use
rcu_dereference() properly.

used in other places where "dead" SMT siblings may need to be taken
online and offline again in order to get into deep idle states.
