Revert "x86/mm/ident_map: Use gbpages only where full GB page should …
…be mapped." [ Upstream commit c567f29 ] This reverts commit d794734. 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 d794734 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: 0a845e0 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: d794734 ("x86/mm/ident_map: Use gbpages only where full GB page should be mapped.")
