Milton Miller 1767c8f392 powerpc: Kexec exit should not use magic numbers ... Commit 54622f10a6 ("powerpc: Support for relocatable kdump kernel") added a magic flag value in a register to tell purgatory that it should be a panic kernel. This part is wrong and is reverted by this commit. The kernel gets a list of memory blocks and a entry point from user space. Its job is to copy the blocks into place and then branch to the designated entry point (after turning "off" the mmu). The user space tool inserts a trampoline, called purgatory, that runs before the user supplied code. Its job is to establish the entry environment for the new kernel or other application based on the contents of memory. The purgatory code is compiled and embedded in the tool, where it is later patched using the elf symbol table using elf symbols. Since the tool knows it is creating a purgatory that will run after a kernel crash, it should just patch purgatory (or the kernel directly) if something needs to happen.
