This is causing a build warning in linux-next:

arch/arm/mach-shmobile/smp-sh73a0.c:45:15: warning: initialization makes integer from pointer without a cast [enabled by default]
arch/arm/mach-shmobile/smp-sh73a0.c:45:15: warning: (near initialization for 'twd_local_timer.res[0].start') [enabled by default]
arch/arm/mach-shmobile/smp-sh73a0.c:45:15: warning: initialization makes integer from pointer without a cast [enabled by default]
/arch/arm/mach-shmobile/smp-sh73a0.c:45:15: warning: (near initialization for 'twd_local_timer.res[0].end') [enabled by default]

The problem is that DEFINE_TWD_LOCAL_TIMER expects a physical
address to pass into ioremap(), while you are passing
an __iomem token.
