code that was thought unnecessary; however, since then KVM has grown quite a few cond_resched()s and for that reason the simplified code is prone to livelocks---one CPUs tries to empty a list of guest page tables while the others keep adding to them. This adds back the generation-based zapping of guest page tables, which was not unnecessary after all. On top of this, there is a fix for a kernel memory leak and a couple of s390 fixlets as well. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAABAgAGBQJdfJcxAAoJEL/70l94x66D8ocH/jhz+95+TBNF5j0xGmBWiDbH zQlWmEMkAQ8o66J+503bc2ltQhM8078Ohumgtmq8HFaRgctDiRdjLBcce6aOr4tH 09gBdlWgkVWLhN8AhydSbHh+SLcCWdZQSAWQrvt1aM2BRdz5WECkUdauSL2oHsTP P58318EL0JrqQaQZtK4qI4eNDiYWdKq2luMu9BTYm3f1Hnk28gorErgBehScYuxE LlnM4RYedH54UR8opdUDmhHxO7bGTW4SVz4obq0sSOJs190DuVbCxbaJjhP+tSwk 7hPac3tHoYFUIhVtgGD3N/LrsFgvcShmjawLP0szCrR2sWrtTqmb0R63DLxpmyg= =yuZ9 -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm fixes from Paolo Bonzini: "The main change here is a revert of reverts.

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.
