commit 18b57ce2eb8c8b9a24174a89250cf5f57c76ecdc upstream For VMEXITs caused by external interrupts, vmx_handle_external_intr() indirectly calls into the interrupt handlers through the host's IDT. It follows that these interrupts get accounted for in the kvm_cpu_l1tf_flush_l1d per-cpu flag. The subsequently executed vmx_l1d_flush() will thus be aware that some interrupts have happened and conduct a L1d flush anyway. Setting l1tf_flush_l1d from vmx_handle_external_intr() isn't needed anymore. Drop it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
