Subject: [GIT PULL] KVM: x86: VMX changes for 6.16

A handful of minor tweaks and fixes, and a big reduction of the boilerplate
needed for forking vt_x86_ops between VMX and TDX.

The following changes since commit 45eb29140e68ffe8e93a5471006858a018480a45:

  KVM: VMX: Clean up and macrofy x86_ops (2025-05-02 13:37:26 -0700)

----------------------------------------------------------------
KVM VMX changes for 6.16:

 - Explicitly check MSR load/store list counts to fix a potential overflow on
   32-bit kernels.

 - Flush shadow VMCSes on emergency reboot.

 - Revert mem_enc_ioctl() back to an optional hook, as it's nullified when
   SEV or TDX is disabled via Kconfig.

 - Macrofy the handling of vt_x86_ops to eliminate a pile of boilerplate code
   needed for TDX, and to optimize CONFIG_KVM_INTEL_TDX=n builds.
