* sh: Define HAVE_FUNCTION_TRACE_MCOUNT_TESTMatt Fleming2009-07-062-1/+17
| | | | | | | | | Enable HAVE_FUNCTION_TRACE_MCOUNT_TEST and test the value of function_trace_stop from our assembly code as opposed to using the generic C function. This should optimise our mcount/ftrace code path. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix the value of MCOUNT_INSN_OFFSETMatt Fleming2009-07-061-2/+2
| | | | | | | | | | It seems that MCOUNT_INSN_OFFSET was calculating the distance between the wrong functions. The value that should have actually been computed is the distance between ftrace_call and ftrace_stub. I discovered this when I added some code to ftrace_caller.

| | | | | | | | | | | | | Use "ceu0" and "ceu1" as CEU names instead of "ceu". This fixes "memchunk" kernel command line selection on the solution engine 7724 board. With this patch applied use "memchunk.ceu0=1m" or "memchunk.ceu1=1m" on kernel command line to override physically memory size to one meg for CEU0 or CEU1.

* sh: SH7786 SMP support.Paul Mundt2009-06-233-24/+18
| | | | | | | | | SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2 CPUs. This just wraps in to the existing SH-X3 SMP code with some minor changes for SH7786, including wiring up the IPIs properly, enabling IRQ_PER_CPU, and so forth.

| | | | | | | | | set_pte_phys() presently uses the global flush_tlb_one(), which locks on SMP trying to do the IPI. As we have not even initialized the other CPUs at this point, switch to the local_ variant so the flush happens on the boot CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* Move FAULT_FLAG_xyz into handle_mm_fault() callersLinus Torvalds2009-06-212-2/+2
| | | | | | | | | | This allows the callers to now pass down the full set of FAULT_FLAG_xyz flags to handle_mm_fault(). All callers have been (mechanically) converted to the new calling convention, there's almost certainly room for architectures to clean up their code and then add FAULT_FLAG_RETRY when that support is added.

| | | | | | | | | | | | | | | | | | | | | | | | | | This adds initial support for the PCI-Express module in the SH7786, particularly as it relates to the urquell platform. Presently it is only supported in root complex mode, with endpoint mode still requiring more debugging. 29/32-bit mode and lane configurations are selectable via board mode pins, and are otherwise fixed. Only 4x and 1x PCI channels are presently handled, the PCI bridge still requires additional debugging and stabilization in hardware. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The LAN9118 controller is hooked up using a 16-bit data bus, but the rsk7203 board does not swap the byte lanes as needed between the sh7203 processor and the the ethernet controller. In the processor the CS memory window is configured in 16-bit mode but the smsc911x driver is told to do 32-bit accesses to improve performance. The SMSC911X_SWAP_FIFO flag is used to tell the driver to do software byte swapping of fifo data.

A continuous loop ensues where we disable interrupts, trace the interrupt disabling, call atomic_* functions, disable interrupts, trace the interrupt disabling, etc.. The simplest solution to all this is to just convert uses of local_irq_save()/local_irq_restore() the raw_* equivalents because the raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().
