From 3133287b53ee88444e2294e601d2bad54a798f59 Mon Sep 17 00:00:00 2001 From: Alexandre Ghiti Date: Thu, 20 Feb 2020 01:10:23 -0500 Subject: [PATCH] riscv: Use p*d_leaf macros to define p*d_huge The newly introduced p*d_leaf macros allow to check if an entry of the page table map to a physical page instead of the next level. To avoid duplication of code, use those macros to determine if a page table entry points to a hugepage.
