From e4ef93edd4e0b022529303db1915766ff9de450e Mon Sep 17 00:00:00 2001 From: Song Shuai Date: Wed, 26 Apr 2023 18:00:09 +0800 Subject: riscv: mm: remove redundant parameter of create_fdt_early_page_table create_fdt_early_page_table() explicitly uses early_pg_dir for 32-bit fdt mapping and the pgdir parameter is redundant here. So remove it and its caller.
