[RFC RESEND v2 07/13] book3s64/hash: Refactor hash__kernel_map_pages() function

From: Ritesh Harjani (IBM)
Date: Mon Oct 14 2024 - 21:37:06 EST


This refactors hash__kernel_map_pages() function to call
hash_debug_pagealloc_map_pages(). This will come useful when we will add
kfence support.

No functionality changes in this patch.
