commit ffcba43ff66c7dab34ec700debd491d2a4d319b4 upstream. The last missing piece to having vmx_l1d_flush() take interrupts after VMEXIT into account is to set the kvm_cpu_l1tf_flush_l1d per-cpu flag on irq entry. Issue calls to kvm_set_cpu_l1tf_flush_l1d() from entering_irq(), ipi_entering_ack_irq(), smp_reschedule_interrupt() and uv_bau_message_interrupt().

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.
