* 'sh-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6:
sh: clkfwk: Build fix for non-legacy CPG changes.
sh: Use GCC __builtin_prefetch() to implement prefetch().
sh: fix vsyscall compilation due to .eh_frame issue
sh: avoid to flush all cache in sys_cacheflush
sh: clkfwk: Disable init clk op for non-legacy clocks.
sh: clkfwk: Kill off now unused algo_id in set_rate op.
sh: clkfwk: Kill off unused clk_set_rate_ex().
