[PATCH 2/2] arm64/ptdump: Replace u64 with pteval_t

From: Anshuman Khandual
Date: Mon Mar 17 2025 - 02:19:16 EST


Page table entry's value, mask and protection are represented with pteval_t
data type format not u64 that has been assumed while dumping the page table
entries. Replace all such u64 instances with pteval_t instead as required.
