patch set about build regression in 3.8 and especially the part about
CONFIG_MULTIPLATFORM made me realized that it could be a problem.
Ok.

Maybe it can be written as

config LOCAL_TIMERS
      bool "Use local timer interrupts"
      depends on SMP
      default y

config HAVE_ARM_TWD
      depends on LOCAL_TIMERS
      default ARCH_MULTIPLATFORM || (!ARCH_MSM_SCORPIONMP && !EXYNOS4_MCT)
So in this case why not written something like this:
        default ARCH_MULTIPLATFORM || (!ARCH_MSM_SCORPIONMP && !EXYNOS4_MCT && !ARMADA_370_XP_TIMER)
That does not change anything, because ARMADA_370_XP_TIMER is only ever enabled
when ARCH_MULTIPLATFORM is enabled as well.
Yes you're right.

So I remove this patch of my series as I don't need it anymore for supporting local
timer on Armada XP/370.

And I will submit this patch as a standalone one.

      default y
I am not a kconfig expert, but won't this line set HAVE_ARM_TWD to 'y' whatever
the result of the previous line?
Yes, that was a mistake on my side.
