Flush only the current context, as opposed to all contexts, when requesting a TLB flush to handle the scenario where a L1 does not expect a TLB flush, but one is required because L1 and L2 shared an ASID. This occurs if EPT is disabled (no per-EPTP tag), VPID is enabled (hardware doesn't flush unconditionally) and vmcs02 does not have its own VPID due to exhaustion of available VPIDs.

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.
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.
