Merge branch 'sh-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6
* '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().

-Clock framework on SuperH architecture
-
-The framework on SH extends existing API by the function clk_set_rate_ex,
-which prototype is as follows:
-
- clk_set_rate_ex (struct clk *clk, unsigned long rate, int algo_id)
-
-The algo_id parameter is used to specify algorithm used to recalculate clocks,
-adjanced to clock, specified as first argument. It is assumed that algo_id==0
-means no changes to adjanced clock
-
-Internally, the clk_set_rate_ex forwards request to clk->ops->set_rate method,
-if it is present in ops structure. The method should set the clock rate and adjust
-all needed clocks according to the passed algo_id.
-Exact values for algo_id are machine-dependent. For the sh7722, the following
-values are defined:
-
- NO_CHANGE = 0,
- IUS_N1_N1, /* I:U = N:1, U:Sh = N:1 */
- IUS_322, /* I:U:Sh = 3:2:2 */
- IUS_522, /* I:U:Sh = 5:2:2 */
- IUS_N11, /* I:U:Sh = N:1:1 */
- SB_N1, /* Sh:B = N:1 */
- SB3_N1, /* Sh:B3 = N:1 */
- SB3_32, /* Sh:B3 = 3:2 */
- SB3_43, /* Sh:B3 = 4:3 */
- SB3_54, /* Sh:B3 = 5:4 */
- BP_N1, /* B:P = N:1 */
- IP_N1 /* I:P = N:1 */
-
-Each of these constants means relation between clocks that can be set via the FRQCR
