Aaron Lu 6876b4804b x86/mm: Use proper mask when setting PUD mapping 
commit 88e0a74902f894fbbc55ad3ad2cb23b4bfba555c 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: c164fbb40c43 ("x86/mm: thread pgprot_t through init_memory_mapping()")
