If anyone has any objections, please let me know. ------------------ From: Anton Blanchard commit 11ee7e99f35ecb15f59b21da6a82d96d2cd3fcc8 upstream. If we build a kernel with CONFIG_RELOCATABLE=y CONFIG_CRASH_DUMP=n, the kernel fails when we run at a non zero offset. It turns out we were incorrectly wrapping some of the relocatable kernel code with CONFIG_CRASH_DUMP.
