From c567f2948f57bdc03ed03403ae0234085f376b7d Mon Sep 17 00:00:00 2001
From: Ingo Molnar <mingo@kernel.org>

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()
