From d47ac2c18744f36112d4fa47a523eb7db1867be9 Mon Sep 17 00:00:00 2001 From: Roy Franz Date: Sun, 22 Sep 2013 15:45:29 -0700 Subject: [PATCH] efi: Rename memory allocation/free functions Rename them to be more similar, as low_free() could be used to free memory allocated by both high_alloc() and low_alloc(). high_alloc() -> efi_high_alloc() low_alloc() -> efi_low_alloc() low_free() -> efi_free() Signed-off-by: Roy Franz Acked-by: Mark Salter Reviewed-by: Grant Likely Signed-off-by: Matt Fleming (cherry picked from commit 40e4530a00b7d52332fe9a1361388fda8e5260da) Signed-off-by: Mark Brown --- arch/x86/boot/compressed/eboot.c | 19 ++++++++++--------- drivers/firmware/efi/efi-stub-helper.c | 14 +++++++------- 2 files changed, 17 insertions(+), 16 deletions(-) diff --git a/arch/x86/boot/compressed/eboot.c b/arch/x86/boot/compressed/eboot.c index 2a3e06e98041..137a0b7a59cf 100644 --- a/arch/x86/boot/compressed/eboot.c +++ b/arch/x86/boot/compressed/eboot.c @@ -897,7 +897,8 @@ struct boot_params *make_boot_params(void *handle, efi_system_table_t *_table) return NULL;
