The KVM introspection subsystem provides a facility for applications
running on the host or in a separate VM, to control the execution of
other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs,
MSRs etc.), alter the page access bits in the shadow page tables (only
for the hardware backed ones, eg. Intel's EPT) and receive notifications
when events of interest have taken place (shadow page table level faults,
key MSR writes, hypercalls etc.). Some notifications can be responded
to with an action (like preventing an MSR from being written), others
are mere informative (like breakpoint events which can be used for
execution tracing).  With few exceptions, all events are optional. An
application using this subsystem will explicitly register for them.

The use case that gave way for the creation of this subsystem is to
monitor the guest OS and as such the ABI/API is highly influenced by how
the guest software (kernel, applications) sees the world. For example,
some events provide information specific for the host CPU architecture
(eg. MSR_IA32_SYSENTER_EIP) merely because its leveraged by guest software
to implement a critical feature (fast system calls).

At the moment, the target audience for KVMI are security software authors
that wish to perform forensics on newly discovered threats (exploits)
or to implement another layer of security like preventing a large set
of kernel rootkits simply by "locking" the kernel image in the shadow
page tables (ie. enforce .text r-x, .rodata rw- etc.). It's the latter
case that made KVMI a separate subsystem, even though many of these
features are available in the device manager. The ability to build a
security application that does not interfere (in terms of performance)
with the guest software asks for a specialized interface that is designed
for minimum overhead.

This patch series is based on kvm/master,
commit 3d9fdc252b52 ("KVM: MIPS: Fix build errors for 32bit kernel").

The previous version (v8) can be read here:

	https://lore.kernel.org/kvm/20200330101308.21702-1-alazar@bitdefender.com/

Patches 1-36: make preparatory changes

Patches 38-82: add basic introspection capabilities

Patch 83: support introspection tools that write-protect guest page tables

Patch 84: notify the introspection tool even on emulation failures
          (when the read/write callbacks used by the emulator,
           kvm_page_preread/kvm_page_prewrite, are not invoked)

Changes since v8:
  - rebase on 5.8
  - fix non-x86 builds (avoid including the UAPI headers from kvmi_host.h)
  - fix the clean-up for KVMI_VCPU_SINGLESTEP [Mathieu]
  - extend KVMI_VM_SET_PAGE_ACCESS with the 'visible' option
  - improve KVMI_VM_GET_MAX_GFN (skip read-only, invalid or non-user memslots)
  - add KVMI_VM_CONTROL_CLEANUP [Tamas, Mathieu]
  - add KVMI_VCPU_GET_XCR and KVMI_VCPU_SET_XSAVE (SSE emulation)
  - move KVM_REQ_INTROSPECTION in the range of arch-independent requests
  - better split of x86 vs arch-independent code
  - cover more error codes with tools/testing/selftests/kvm/x86_64/kvmi_test.c
  - remove more error messages and close the introspection connection
    when an error code can't be sent back or it doesn't make sense to send it
  - other small changes (code refactoring, message validation, etc.).
