2008-09-05sh: resume_kernel fix for kernel oops built with CONFIG_BKL_PREEMPT=y.Carmelo Amoroso1-24/+3
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.

2008-08-28sh: fix kexec entry point for crash kernelsMagnus Damm1-1/+1
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.

2008-08-28sh: crash kernel resource fixMagnus Damm1-5/+1
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 Yoshii1-0/+10
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.
