pasta from the corresponding s390 code screwed up the address calculation for marking the sub-pmd ranges via memset by omitting the ALIGN_DOWN() to calculate the proper start address. It's a mystery why this code is not generic and shared because there is nothing architecture specific in there, but that's too intrusive for a backportable fix. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmKAxpUTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoce3EACRBl9gb+3gU/qXcjyM09AaqIYo084t ewJnbsmvM7y0zCqgEKB7TKzQ7DEcrzz+woATWkEI3WiC12SYh3OAd8MfoTkp9p3n RlGtlqXozus0fppbkiXUyrOcWZjAFsTXpKNqZr1xTDaAJjQYlhgZKo7kedUDhe2N 5IX5ss/cZM/mnUR+AFY55jQR6pEnMY3qjC5vTVd/nqPIo8T6ZvLmmXdm8HnF1f+Y a64h9PpvjOHfGw+ljFaMUtIH6JEpyIomai1VUFbhYyaiTVFI2AZVkvuHS2Pg18/R NPWDjNozd9PBRlYcvXWmFyNCe4CuCAq6hy3IctVUUINVg7+/68mRoLxnFaWYaQcx dl1bUE0F6I1XWRxLMx7uUWHffVyY8bomPB2koNII+AqgMOoKaUT1pNWPQzSQw0aw Etjb2pVj9sfJ84VOfzlh7SObAU/Bf7lCXNUpNXvEPH71L/B4cIe+XpvWgNB1Ezpz gXX6TLxmlPnwJokmeQ/gnO+bWGsjBRNu+cCsLHu2MGFuFJyPePhBMNvfnBv/A0jG 9lTq9zztiWJO2iu/TC/wRA21SBMvmipz23DIdv5Jhl0b+mP/qOSPQpZu9P3bRPIu C4X8nQLP4DDF4juRJtgFqKdfI9A9h50phnvrOaOPn7Lnrx99Hbg0/2h9bU7lA2Ly qe9+nz/i5CAC6w== =f+jf -----END PGP SIGNATURE----- Merge tag 'x86-urgent-2022-05-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fix from Thomas Gleixner: "A single fix for the handling of unpopulated sub-pmd spaces.

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.
