From 91e9ee7e949bff08cc3845a4811185e826b6e2f1 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Mon, 7 Jun 2021 10:56:06 +0000 Subject: [PATCH] powerpc/32s: Rename PTE_SIZE to PTE_T_SIZE PTE_SIZE means PTE page table size in most placed, whereas in hash_low.S in means size of one entry in the table. Rename it PTE_T_SIZE, and define it directly in hash_low.S instead of going through asm-offsets.
