commit c567f2948f57bdc03ed03403ae0234085f376b7d upstream. This reverts commit d794734c9bbfe22f86686dc2909c25f5ffe1a572. While the original change tries to fix a bug, it also unintentionally broke existing systems, see the regressions reported at: https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/ Since d794734c9bbf was also marked for -stable, let's back it out before causing more damage. Note that due to another upstream change the revert was not 100% automatic: 0a845e0f6348 mm/treewide: replace pud_large() with pud_leaf() Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: <stable@vger.kernel.org> Cc: Russ Anderson <rja@hpe.com> Cc: Steve Wahl <steve.wahl@hpe.com> Cc: Dave Hansen <dave.hansen@linux.intel.com> Link: https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/ Fixes: d794734c9bbf ("x86/mm/ident_map: Use gbpages only where full GB page should be mapped.")

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.
