Liran Alon 327c072187 KVM: nVMX: Flush linear and combined mappings on VPID02 related flushes
All VPID12s used on a given L1 vCPU is translated to a single
VPID02 (vmx->nested.vpid02 or vmx->vpid). Therefore, on L1->L2 VMEntry,
we need to invalidate linear and combined mappings tagged by
VPID02 in case L1 uses VPID and vmcs12->vpid was changed since
last L1->L2 VMEntry.

However, current code invalidates the wrong mappings as it calls
__vmx_flush_tlb() with invalidate_gpa parameter set to true which will
result in invalidating combined and guest-physical mappings tagged with
active EPTP which is EPTP01.

Similarly, INVVPID emulation have the exact same issue.

Fix both issues by just setting invalidate_gpa parameter to false which
will result in invalidating linear and combined mappings tagged with
given VPID02 as required.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
