[PATCH -next v5 1/5] mm: page_table_check: using PxD_SIZE instead of PxD_PAGE_SIZE

[Tong Tiangen <tongtiangen@huawei.com>]

Macro PUD_SIZE/PMD_SIZE is more general in various architectures. Using
PUD_SIZE/PMD_SIZE instead of PUD_PAGE_SIZE/PMD_PAGE_SIZE can better
support page table check in architectures other than x86 and it is no
functional impact on x86.
