ARM: Remove __ref on hotplug cpu die path

2015-10-22T16:55:03Z

Now that __cpuinit has been removed, the __ref markings on these functions are useless. Remove them. This also reduces the size of the multi_v7_defconfig image: $ size before after text data bss dec hex filename 12683578 1470996 348904 14503478 dd4e36 before 12683274 1470996 348904 14503174 dd4d06 after presumably because now we don't have to jump to code in the .ref.text section and/or the noinline marking is removed.

Remove the majority of cache flushing calls from the individual platform files. This is now handled by the core code. Signed-off-by: Russell King

ARM: prima2: fix __init section for cpu hotplug

2013-02-14T13:36:35Z

The code in arch/arm/mach-prima2/headsmp.S is used for both boot time initialization and for cpu hotplug, so it must not be discarded after the initial boot is complete. This replaces the __INIT annotation with __CPUINIT, and marks the sirfsoc_cpu_die as __ref to annotate that it correctly uses the sections. Without this patch, building prima2_defconfig results in: WARNING: arch/arm/mach-prima2/built-in.o(.cpuinit.text+0x130): Section mismatch in reference from the function sirfsoc_boot_secondary() to the function .init.text:sirfsoc_secondary_startup() The function __cpuinit sirfsoc_boot_secondary() references a function __init sirfsoc_secondary_startup(). If sirfsoc_secondary_startup is only used by sirfsoc_boot_secondary then annotate sirfsoc_secondary_startup with a matching annotation. Signed-off-by: Arnd Bergmann Cc: Barry Song

ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructures

2013-01-22T11:53:27Z

this patch adds tick timer, smp entries and generic DT machine for SiRFmarco dual-core SMP chips. with the added marco, we change the defconfig, using the same defconfig, we get a zImage which can work on both prima2 and marco. Signed-off-by: Barry Song Cc: Mark Rutland
