Subject: [PATCH] KVM: x86: emulator: em_sysexit should update ctxt->mode
This is one of the instructions that can change the
processor mode.
Note that this is likely a benign bug, because the only problematic
mode change is from 32 bit to 64 bit which can lead to truncation of RIP,
and it is not possible to do with sysexit,
since sysexit running in 32 bit mode will be limited to 32 bit version.

Subject: [PATCH] KVM: x86: emulator: introduce emulator_recalc_and_set_mode
Some instructions update the cpu execution mode, which needs
to update the emulation mode.
Extract this code, and make assign_eip_far use it.
assign_eip_far now reads CS, instead of getting it via a parameter,
which is ok, because callers always assign CS to the
same value before calling it.
No functional change is intended.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Maxim Levitsky <mlevitsk@redhat.com>
Date: Wed, 3 Aug 2022 18:50:03 +0300
Subject: [PATCH] KVM: x86: emulator: update the emulation mode after CR0 write
CR0.PE toggles real/protected mode, thus its update
should update the emulation mode.
This is likely a benign bug because there is no writeback
of state, other than the RIP increment, and when toggling
CR0.PE, the CPU has to execute code from a very low memory address.
Also CR0.PG toggle when EFER.LMA is set, toggles the long mode.
