Pull USB fixes from Greg KH:
"Here are some small USB fixes for a few reported issues. Included in
here are:
- xhci fix for a _much_ reported regression. I don't think there's a
community distro that has not reported this problem yet :(
- new USB quirk addition
- cdns3 minor fixes
- typec regression fix.
All of these have been in linux-next with no reported problems, and
the xhci fix has been reported by many to resolve their reported
problem"

Pull x86 fixes from Borislav Petkov:
- Fix a couple of SWAPGS fencing issues in the x86 entry code
- Use the proper operand types in __{get,put}_user() to prevent
truncation in SEV-ES string io
- Make sure the kernel mappings are present in trampoline_pgd in order
to prevent any potential accesses to unmapped memory after switching
to it
- Fix a trivial list corruption in objtool's pv_ops validation
- Disable the clocksource watchdog for TSC on platforms which claim
that the TSC is constant, doesn't stop in sleep states, CPU has TSC
adjust and the number of sockets of the platform are max 2, to
prevent erroneous markings of the TSC as unstable.
- Make sure TSC adjust is always checked not only when going idle
- Prevent a stack leak by initializing struct _fpx_sw_bytes properly in
the FPU code

Currently, an SEV-ES guest is terminated if the validation of the VMGEXIT
exit code or exit parameters fails.
The VMGEXIT instruction can be issued from userspace, even though
userspace (likely) can't update the GHCB. To prevent userspace from being
able to kill the guest, return an error through the GHCB when validation
fails rather than terminating the guest. For cases where the GHCB can't be
updated (e.g. the GHCB can't be mapped, etc.), just return back to the
guest.
The new error codes are documented in the lasest update to the GHCB
specification.

Use kvzalloc() to allocate KVM's buffer for SEV-ES's GHCB scratch area so that KVM falls back to __vmalloc() if physically contiguous memory isn't available. The buffer is purely a KVM software construct, i.e. there's no need for it to be physically contiguous.
