From: "Guo Ren (Alibaba DAMO Academy)" <guoren@kernel.org> If phyical memory is 1GiB for ilp32 linux, then print_mlk would be: lowmem : 0xc0000000 - 0x00000000 ( 1024 MB) After fixup: lowmem : 0xc0000000 - 0xffffffff ( 1024 MB) Signed-off-by: Guo Ren (Alibaba DAMO Academy) <guoren@kernel.org> --- arch/riscv/mm/init.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
