commit 88e0a74902 upstream.
Commit c164fbb40c43f("x86/mm: thread pgprot_t through
init_memory_mapping()") mistakenly used __pgprot() which doesn't respect
__default_kernel_pte_mask when setting PUD mapping.
Fix it by only setting the one bit we actually need (PSE) and leaving
the other bits (that have been properly masked) alone.
Fixes: c164fbb40c ("x86/mm: thread pgprot_t through init_memory_mapping()")
