From 75305275a721d33ae9abfaeed2817cec8b2fee9a Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 15 Nov 2015 10:39:53 +0900 Subject: ARM: use const and __initconst for smp_operations These smp_operations structures are not over-written, so add "const" qualifier and replace __initdata with __initconst. Also, add "static" where it is possible.

Please notice the difference between config ARCH_FOO bool "Foo SoCs" if ARCH_MULTI_V7 and config ARCH_FOO bool "Foo SoCs" depends on ARCH_MULTI_V7 These two are *not* equivalent! In the former statement, it is not ARCH_FOO, but its prompt that depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO is selected by another, but ARCH_MULTI_V7 is still disabled. As it is not unmet dependency, Kconfig never warns. This is probably not what you want. The former should be used only when you need to do so, and you really understand what you are doing. (In most cases, it should be wrong!) For enabling/disabling sub-architectures, the latter is always correct. As a good side effect, this commit fixes some entries over 80 columns (mach-imx, mach-integrator, mach-mbevu). [Arnd: I note that there is not really a bug here, according to the discussion that followed, but I can see value in being consistent and in making the lines shorter] Signed-off-by: Masahiro Yamada Acked-by: Maxime Ripard Acked-by: Nicolas Ferre Acked-by: Heiko Stuebner Acked-by: Patrice Chotard Acked-by: Liviu Dudau Acked-by: Krzysztof Kozlowski Acked-by: Jun Nie Acked-by: Matthias Brugger Acked-by: Simon Horman Acked-by: Gregory CLEMENT Acked-by: Shawn Guo Acked-by: Sebastian Hesselbarth Acked-by: Thierry Reding Acked-by: Krzysztof Halasa Acked-by: Maxime Coquelin Signed-off-by: Arnd Bergmann --- arch/arm/mach-sti/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'arch/arm/mach-sti') diff --git a/arch/arm/mach-sti/Kconfig b/arch/arm/mach-sti/Kconfig index 125865daaf17..736abe6d01dc 100644 --- a/arch/arm/mach-sti/Kconfig +++ b/arch/arm/mach-sti/Kconfig @@ -1,5 +1,6 @@ menuconfig ARCH_STI - bool "STMicroelectronics Consumer Electronics SOCs" if ARCH_MULTI_V7 + bool "STMicroelectronics Consumer Electronics SOCs" + depends on ARCH_MULTI_V7 select ARM_GIC select ST_IRQCHIP select ARM_GLOBAL_TIMER -- cgit
