Author: nwhitehorn Date: Sat Nov 25 21:45:51 2017 New Revision: 326203 URL: https://svnweb.freebsd.org/changeset/base/326203 Log: Avoid emitting a PT_INTERP section for powerpc64 kernels and arrange for the first instruction to be at the start of the text segment. This allows the kernel to be booted correctly by stock kexec-lite.
