Hoping you compiled it on all machs: > > Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> I built many thousand kernels with this patch, but also had other patches applied at the same time, notably the s3c64xx multiplatform series, so I can make a reasonable assumption that I'm not introducing regressions, unless it relies on something else I have queued up and not yet sent.

For a long time, gcc has warned about odd configurations on s3c64xx: In file included from arch/arm/plat-samsung/pm.c:34:0: arch/arm/mach-s3c64xx/include/mach/pm-core.h:61:0: warning: "s3c_irqwake_eintallow" redefined #define s3c_irqwake_eintallow ((1 << 28) - 1) In file included from arch/arm/plat-samsung/pm.c:33:0: arch/arm/plat-samsung/include/plat/pm.h:49:0: note: this is the location of the previous definition #define s3c_irqwake_eintallow 0 The definitions of s3c_irqwake_intallow and s3c_irqwake_eintallow are a bit consistent between the various platforms. Things have become easier now that it's only s3c24xx and s3c64xx that use them at all, so I've tried to rearrange the definitions to make it more obvious what is going on.
