powerpc: Support for relocatable kdump kernel

2008-10-22T04:01:22Z

This adds relocatable kernel support for kdump. With this one can use the same regular kernel to capture the kdump. A signature (0xfeed1234) is passed in r6 from panic code to the next kernel through kexec_sequence and purgatory code. The signature is used to differentiate between kdump kernel and non-kdump kernels. The purgatory code compares the signature and sets the __kdump_flag in head_64.S. During the boot up, kernel code checks __kdump_flag and if it is set, the kernel will behave as relocatable kdump kernel. This kernel will boot at the address where it was loaded by kexec-tools ie. at the address reserved through crashkernel boot parameter. CONFIG_CRASH_DUMP depends on CONFIG_RELOCATABLE option to build kdump kernel as relocatable. So the same kernel can be used as production and kdump kernel. This patch incorporates the changes suggested by Paul Mackerras to avoid GOT use and to avoid two copies of the code.

kexec: make extended crashkernel= syntax less confusing

2008-05-01T15:04:00Z

The extended crashkernel syntax is a little confusing in the way it handles ranges. eg: crashkernel=512M-2G:64M,2G-:128M Means if the machine has between 512M and 2G of memory the crash region should be 64M, and if the machine has 2G of memory the region should be 64M. Only if the machine has more than 2G memory will 128M be allocated. Although that semantic is correct, it is somewhat baffling. Instead I propose that the end of the range means the first address past the end of the range, ie: 512M up to but not including 2G.
