-From c567f2948f57bdc03ed03403ae0234085f376b7d Mon Sep 17 00:00:00 2001
-From: Ingo Molnar <mingo@kernel.org>
-Date: Mon, 25 Mar 2024 11:47:51 +0100
-Subject: Revert "x86/mm/ident_map: Use gbpages only where full GB page should
- be mapped."
-
-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>

-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.")
