Actually I am the one to blame for build failure (commit: "ARM: EXYNOS: Move code from hotplug.c to platsmp.c"). The problem is v7_exit_coherency_flush() which I think does not make sense on ARMv6.
I'll replace the ISB and DSB commands with macros but the real question is whether the mach-exynos/platsmp.c file and mach-exynos directory should be compiled when CONFIG_ARCH_EXYNOS is not defined?
Best regards, Krzysztof

It's entirely possible that a kernel will be configured to support ARMv6 and ARMv7, which can also include exynos support. In this case, it will be built using compiler flags for ARMv6, since ARMv7 is compatible with the ARMv6 ISA (even though a few instructions are deprecated.)

Actually I am the one to blame for build failure (commit: "ARM: EXYNOS: Move code from hotplug.c to platsmp.c"). The problem is v7_exit_coherency_flush() which I think does not make sense on ARMv6.
I'll replace the ISB and DSB commands with macros but the real question is whether the mach-exynos/platsmp.c file and mach-exynos directory should be compiled when CONFIG_ARCH_EXYNOS is not defined?
I think the problematic case here is v6+v7 multiplatform, where even though CONFIG_ARCH_EXYNOS is defined, compiler flags for lowest common denominator (v6) must be used. Using appropriate macros should fix the problem indeed.
Best regards, Tomasz

Right, multiplatform ends up generating such a configuration.
