2008-09-08sh: Display CPU information in show_regs().Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: Early dummy clockevent registration on boot CPU.Paul Mundt
The dummy timer needs to be registered on the boot CPU before the system timer clockevent is registered, or broadcasting doesn't work as advertized. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: smp: shove a cpu_relax() in the plat_start_cpu() busy loop.Paul Mundt
Without this, certain versions of GCC will happily optimize the entire loop out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: generic clockevent broadcast support.Paul Mundt
This hooks up GENERIC_CLOCKEVENTS_BROADCAST and a dummy local timer, which we call in to from the timer IPI when no other local timer is provided. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: smp: Hook up a timer IPI stub.Paul Mundt

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08sh: smp: Provide a generic IPI handler.Paul Mundt
This provides a generic smp_message_recv() routine (based on the PPC one), that IPI IRQs can wrap in to. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-05sh64: resume_kernel fix for kernel oops built with CONFIG_BKL_PREEMPT=y.Paul Mundt
Follows the SH change. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-05sh: resume_kernel fix for kernel oops built with CONFIG_BKL_PREEMPT=y.Carmelo Amoroso
This patch fixes a problem within the SH implementation of resume_kernel code, that implements in assembly the bulk of preempt_schedule_irq function without taking care of the extra code needed to handle the BKL preemptible. The patch basically consists of removing this asm code and calling the common C implementation (see kernel/sched.c) as other archs do. Another change is the missing 'cli' macro invocation at the beginning of the resume_kernel.

This patch kills a section mismatch for platform_resource_setup_memory(). Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-28sh: fix kexec entry point for crash kernelsMagnus Damm
The crash kernel entry point is currently checked by the kexec kernel code and only physical addresses in the reserved memory window are accepted. This means that we can't pass P2 or P1 addresses as entry points in the case of crash kernels. This patch makes sure we can start crash kernels by adding support for physical address entry points. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-28sh: crash kernel resource fixMagnus Damm
The reserved crash kernel memory range is currently missing from /proc/iomem. crashk_res is mistakenly setup after __add_active_range(). Reorder things to make sure the resource shows up in /proc/iomem. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-08-04add addrespace definition for sh2a.Takashi Yoshii
Newfile: arch/sh/include/cpu-sh2a/cpu/addrspace.h This file seems had be removed to use fallback (cpu-common/cpu/addrspace.h), but, I'd like to add sh2a specific file here, because 1. the values defined there are not suitable for sh2a. 2. I don't think there is "common" definition for these values. Values are chosen by consideration of followings... P1 is 0. perhaps no question. P2 is from hardware manual, which says no-cache area starts at 20000000. It means that P? space size=20000000. P3 is P2+size since asm/ptrace.h uses P3 as a end of P2. P4 is P3+size since asm/fixup.h uses P4 as a end of P3. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
