sh: resume_kernel fix for kernel oops built with CONFIG_BKL_PREEMPT=y.

2008-09-05T05:42:16Z

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. Signed-off-by: Giuseppe Cavallaro Signed-off-by: Carmelo Amoroso Signed-off-by: Paul Mundt

sh: fix kexec entry point for crash kernels

2008-08-28T05:53:03Z

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.

sh: crash kernel resource fix

2008-08-28T05:52:58Z

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 Signed-off-by: Paul Mundt

sh: export sh7723 VEU as VEU2H

2008-08-11T11:17:55Z

Export sh7723 VEU hardware blocks as VEU2H. The sh7723 VEU2H differs a bit from the sh7722 VEU so use different names for our UIO devices. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: Save NUMA node data in vmcore for crash dumps.

2008-08-04T04:42:49Z

Presently the NUMA node data isn't saved on kexec. This implements a simple arch_crash_save_vmcoreinfo() for saving off the relevant data. Signed-off-by: Paul Mundt

sh: module_alloc() should be using vmalloc_exec().

2008-08-04T04:34:29Z

SH-X2 extended mode TLB allows for toggling of the exec bit, so make sure we are using the right protection bits for module space there also. Signed-off-by: Paul Mundt
