Pull driver core api addition from Greg KH:
 "Here is a driver core new api for 6.14-rc3 that is being added to
  allow platform devices from stop being abused.

  It adds a new 'faux_device' structure and bus and api to allow almost
  a straight or simpler conversion from platform devices that were not
  really a platform device. It also comes with a binding for rust, with
  an example driver in rust showing how it's used.

  I'm adding this now so that the patches that convert the different
  drivers and subsystems can all start flowing into linux-next now
  through their different development trees, in time for 6.15-rc1.

  We have a number that are already reviewed and tested, but adding
  those conversions now doesn't seem right. For now, no one is using
  this, and it passes all build tests from 0-day and linux-next, so all
  should be good"

Pull kvm fixes from Paolo Bonzini:
 "ARM:

   - Large set of fixes for vector handling, especially in the
     interactions between host and guest state.

     This fixes a number of bugs affecting actual deployments, and
     greatly simplifies the FP/SIMD/SVE handling. Thanks to Mark Rutland
     for dealing with this thankless task.

   - Fix an ugly race between vcpu and vgic creation/init, resulting in
     unexpected behaviours

   - Fix use of kernel VAs at EL2 when emulating timers with nVHE

   - Small set of pKVM improvements and cleanups

  x86:

   - Fix broken SNP support with KVM module built-in, ensuring the PSP
     module is initialized before KVM even when the module
     infrastructure cannot be used to order initcalls

   - Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being
     emulated by KVM to fix a NULL pointer dereference

   - Enter guest mode (L2) from KVM's perspective before initializing
     the vCPU's nested NPT MMU so that the MMU is properly tagged for
     L2, not L1

   - Load the guest's DR6 outside of the innermost .vcpu_run() loop, as
     the guest's value may be stale if a VM-Exit is handled in the
     fastpath"

KVM fixes for 6.14 part 1

 - Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being emulated
   by KVM to fix a NULL pointer dereference.

 - Enter guest mode (L2) from KVM's perspective before initializing the vCPU's
   nested NPT MMU so that the MMU is properly tagged for L2, not L1.

 - Load the guest's DR6 outside of the innermost .vcpu_run() loop, as the
   guest's value may be stale if a VM-Exit is handled in the fastpath.

KVM is dependent on the PSP SEV driver and PSP SEV driver needs to be
loaded before KVM module. In case of module loading any dependent
modules are automatically loaded but in case of built-in modules there
is no inherent mechanism available to specify dependencies between
modules and ensure that any dependent modules are loaded implicitly.

Add a new external API interface for PSP module initialization which
allows PSP SEV driver to be loaded explicitly if KVM is built-in.

Pull EFI fixes from Ard Biesheuvel:
 "Take the newly introduced EFI_MEMORY_HOT_PLUGGABLE memory attribute
  into account when placing the kernel image in memory at boot.

  Otherwise, the presence of the kernel image could prevent such a
  memory region from being unplugged at runtime if it was 'cold
  plugged', i.e., already plugged in at boot time (and exposed via the
  EFI memory map).

  This should ensure that the new EFI_MEMORY_HOT_PLUGGABLE memory
  attribute is used consistently by Linux before it ever turns up in
  production, ensuring that we can make meaningful use of it without
  running the risk of regressing existing users"

This reverts commit 011b0335903832facca86cd8ed05d7d8d94c9c76.

Sabrina reports that the revert may trigger warnings due to intervening
changes, especially the ability to rise MAX_SKB_FRAGS. Let's drop it
and revisit once that part is also ironed out.

Many drivers abuse the platform driver/bus system as it provides a
simple way to create and bind a device to a driver-specific set of
probe/release functions.  Instead of doing that, and wasting all of the
memory associated with a platform device, here is a "faux" bus that
can be used instead.
