From: James Hogan <jhogan@xxxxxxxxxx> Use CONFIG_ARCH_SUPPORTS_OPTIMIZED_INLINING and CONFIG_OPTIMIZE_INLINING instead of undefining the inline macros in the alpha specific asm/compiler.h. This is to allow asm/compiler.h to become a general header that can be used for overriding linux/compiler*.h. A build of alpha's defconfig on GCC 7.3 before and after this series (i.e. this commit and "compiler.h: Allow arch-specific overrides" which includes asm/compiler.h from linux/compiler_types.h) results in the following size differences, which appear harmless to me: $ ./scripts/bloat-o-meter vmlinux.1 vmlinux.2 add/remove: 1/1 grow/shrink: 3/0 up/down: 264/-348 (-84) Function old new delta cap_bprm_set_creds 1496 1664 +168 cap_issubset - 68 +68 flex_array_put 328 344 +16 cap_capset 488 500 +12 nonroot_raised_pE.constprop 348 - -348 Total: Before=5823709, After=5823625, chg -0.00% Suggested-by: Arnd Bergmann <arnd@xxxxxxxx> Signed-off-by: James Hogan <jhogan@xxxxxxxxxx> Signed-off-by: Paul Burton <paul.burton@xxxxxxxx> Acked-by: Matt Turner <mattst88@xxxxxxxxx> Cc: Richard Henderson <rth@xxxxxxxxxxx> Cc: Ivan Kokshaysky <ink@xxxxxxxxxxxxxxxxxxxx> Cc: linux-alpha@xxxxxxxxxxxxxxx --- Changes in v5: None Changes in v4: None Changes in v3: - New patch in v3. arch/alpha/Kconfig | 6 ++++++ arch/alpha/include/asm/compiler.h | 11 ----------- 2 files changed, 6 insertions(+), 11 deletions(-) diff --git a/arch/alpha/Kconfig b/arch/alpha/Kconfig index 04a4a138ed13..649b41621520 100644 --- a/arch/alpha/Kconfig +++ b/arch/alpha/Kconfig @@ -74,6 +74,12 @@ config PGTABLE_LEVELS int default 3 +config ARCH_SUPPORTS_OPTIMIZED_INLINING + def_bool y + +config OPTIMIZE_INLINING + def_bool y + source "init/Kconfig" source "kernel/Kconfig.freezer" diff --git a/arch/alpha/include/asm/compiler.h b/arch/alpha/include/asm/compiler.h index 5159ba259d65..ae645959018a 100644 --- a/arch/alpha/include/asm/compiler.h +++ b/arch/alpha/include/asm/compiler.h @@ -4,15 +4,4 @@ #include <uapi/asm/compiler.h> -/* Some idiots over in <linux/compiler.h> thought inline should imply - always_inline.
