2009-06-14sh: Bump the earlytimer probe devices up.Paul Mundt
Presently the earlytimer probe handles the clockevents driver, which requires that the clockevents driver be registered first. This bumps it up by 1 to include the clocksource device, which can be safely ignored if it doesn't exist, as we will simply error out on that path and defer to the jiffies clocksource.

2009-06-14sh: Use generic sched_clock().Paul Mundt
The generic sched_clock() handles INITIAL_JIFFIES now as well, so we can just use that instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-14sh: Bump the earlytimer bits back to time_init().Paul Mundt
These were handled through late_time_init due to kmalloc() and friends not being available earlier on previously. Now with slab caches being available much earlier, this is no longer necessary, and we can move the initialization up to an earlier point. One of the benefits with this is that printk times are available a bit earlier! Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-06-14cpumask: use mm_cpumask() wrapper: shRusty Russell
Makes code futureproof against the impending change to mm->cpu_vm_mask. It's also a chance to use the new cpumask_ ops which take a pointer (the older ones are deprecated, but there's no hurry for arch code).

2009-06-14cpumask: arch_send_call_function_ipi_mask: shRusty Russell
We're weaning the core code off handing cpumask's around on-stack. This introduces arch_send_call_function_ipi_mask(), and by defining it, the old arch_send_call_function_ipi is defined by the core code.

2009-06-11sh: Fix dynamic ftrace's NOP action.Matt Fleming
Ftrace on sh handles nop'ing out trace function calls differently than other architectures. Instead of inserting NOP instructions in place of the call to the function tracer we branch over the call instructions and continue executing the main body of the function. This patch fixes a bug in the implementation of ftrace_modify_code() where we check that the old value of the code we're about to replace is an expected one. In the ftrace_make_call() code path ftrace_modify_code() was comparing the old instruction value with NOP instructions. The compare was failing because we never actually insert NOP instructions. It makes sense to just get rid of the NOP instructions in ftrace_nop and compare the old code with the address of the function body if we're expecting ftrace to have nop'd out the function trace call.

2009-06-11sh: Tie sparseirq in to Kconfig.Paul Mundt
Now that the dependent patches are merged, we are ready to enable sparseirq support. This simply adds the Kconfig option, and then converts from the _cpu to the _node allocation routines to follow the upstream sparseirq API changes. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This fixes up a typo in the ll/sc based cmpxchg code which apparently wasn't getting a lot of testing due to the swapped old/new pair.

This patch reworks the mode pin code to keep the pin definitions in one place. The mode pins values are now the value of the bit instead of bit number. With this patch in place the sh7785 header file contains mode pin comments. The sh7785 clock code and the sh7785lcr board code are updated to reflect the new shared mode pins.

2009-06-01sh: Tidy up SH-4A boot_cpu_data.flags probing.Paul Mundt
This tidies up the boot_cpu_data.flags probing on SH-4A. All of them have a few things in common, which we can blindly set, rather than having each subtype have to set the same flags. We can also make assumptions about cache ways and the validity of PTEA, so this also kills off CPU_HAS_PTEA as a config option. There was also a bug in the FPU probing, which is now tidied up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-01sh: Tidy up the optional L2 probing, wire it up for SH7786.Paul Mundt
This tidies up the L2 probing, as it may or may not be implemented on a CPU, regardless of whether it is supported. This converts the cvr validity checks from BUG_ON()'s to simply clearing the CPU_HAS_L2_CACHE flag and moving on with life. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
