From da2d48808fbd1eddefefe245c6c0e92a9195df8b Mon Sep 17 00:00:00 2001 From: Wende Tan Date: Sat, 22 May 2021 17:49:51 +0000 Subject: [PATCH] RISC-V: Fix memblock_free() usages in init_resources() `memblock_free()` takes a physical address as its first argument. Fix the wrong usages in `init_resources()`. Fixes: ffe0e526126884cf036a6f724220f1f9b4094fd2 ("RISC-V: Improve init_resources()") Fixes: 797f0375dd2ef5cdc68ac23450cbae9a5c67a74e ("RISC-V: Do not allocate memblock while iterating reserved memblocks") Signed-off-by: Wende Tan Signed-off-by: Palmer Dabbelt --- arch/riscv/kernel/setup.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/riscv/kernel/setup.c b/arch/riscv/kernel/setup.c index 03901d3a8b02..9a1b7a0603b2 100644 --- a/arch/riscv/kernel/setup.c +++ b/arch/riscv/kernel/setup.c @@ -231,13 +231,13 @@ static void __init init_resources(void) /* Clean-up any unused pre-allocated resources */ mem_res_sz = (num_resources - res_idx + 1) * sizeof(*mem_res); - memblock_free((phys_addr_t) mem_res, mem_res_sz); + memblock_free(__pa(mem_res), mem_res_sz); return; error: /* Better an empty resource tree than an inconsistent one */ release_child_resources(&iomem_resource); - memblock_free((phys_addr_t) mem_res, mem_res_sz); + memblock_free(__pa(mem_res), mem_res_sz); }
