When injecting a page fault or EPT violation/misconfiguration, KVM is not syncing any shadow PTEs associated with the faulting address, including those in previous MMUs that are associated with L1's current EPTP (in a nested EPT scenario), nor is it flushing any hardware TLB entries. All this is done by kvm_mmu_invalidate_gva. Page faults that are either !PRESENT or RSVD are exempt from the flushing, as the CPU is not allowed to cache such translations.

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.
