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

     fastpath"

The Tegra210 Audio DMA controller driver did a plain divide:

	page_no = (res_page->start - res_base->start) / cdata->ch_base_offset;

which causes problems on 32-bit x86 configurations that have 64-bit
resource sizes:

  x86_64-linux-ld: drivers/dma/tegra210-adma.o: in function `tegra_adma_probe':
  tegra210-adma.c:(.text+0x1322): undefined reference to `__udivdi3'

because gcc doesn't generate the trivial code for a 64-by-32 divide,
turning it into a function call to do a full 64-by-64 divide.  And the
kernel intentionally doesn't provide that helper function, because 99%
of the time all you want is the narrower version.

Of course, tegra210 is a 64-bit architecture and the 32-bit x86 build is
purely for build testing, so this really is just about build coverage
failure.

But build coverage is good.

Side note: div_u64() would be suboptimal if you actually have a 32-bit
resource_t, so our "helper" for divides are admittedly making it harder
than it should be to generate good code for all the possible cases.

At some point, I'll consider 32-bit x86 so entirely legacy that I can't
find it in myself to care any more, and we'll just add the __udivdi3
library function.

But for now, the right thing to do is to use "div_u64()" to show that
you know that you are doing the simpler divide with a 32-bit number.
And the build error enforces that.

While fixing the build issue, also check for division-by-zero, and for
overflow.  Which hopefully cannot happen on real production hardware,
but the value of 'ch_base_offset' can definitely be zero in other
places.
