From e17362d683fb6bcda0e419ec0ad7cabb8252c509 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 17 Jun 2021 11:50:49 +0100 Subject: [PATCH] ARM: 9097/1: mmu: Declare section start/end correctly The kernel test robot reported an interesting bug: A debug print was using %08x with kernel_sec_start and kernel_sec_end being phys_addr_t which can be either u32 or u64 (possibly more). Actually these should just be declared as u32 to begin with: they are declared as such in the assembly in head.S and the kernel definitely boots in a 32 bit physical address space. Redeclare the kernel_sec_start and kernel_sec_end to rid the bug.
