Subject: arm64: mm: call PUD/P4D ctor in __create_pgd_mapping()
Date: Tue, 8 Apr 2025 10:52:21 +0100

Constructors for PUD/P4D-level pgtables were recently introduced.  They
should be called for all pgtables; make sure they are called for special
kernel mappings created by __create_pgd_mapping() too.
