This involves thefollowing pieces:- Making the first instruction a valid kernel entry point, since kexec ignores the ELF entry value. This requires a separate section and linker magic to prevent the linker from filling the beginning of the section with stubs.- Adding an entry point at 0x60 past the first instruction for systems lacking firmware CPU shutdown support (notably PS3).- Linker script changes to support the above.MFC after: 1 month List of files: /freebsd-12.1/sys/conf/ldscript.powerpc64 Fri, 29 Dec 2017 20:30:10 +0000 Nathan Whitehorn <nwhitehorn@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/sys/conf/ldscript.powerpc64#7cc0ad62 Make __startkernel line up with KERNBASE, so that the math to compute theapplied relocation offset in link_elf.c works as intended. We may want torevisit how that works in future, for example by having elf_reloc_self()actually store the numbers it is using rather than computing them later,but this fixes symbol lookup after r326203.Reported by: andreast@Pointy hat to: me List of files: /freebsd-12.1/sys/conf/ldscript.powerpc64 Tue, 19 Dec 2017 15:50:46 +0000 Nathan Whitehorn <nwhitehorn@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/sys/conf/ldscript.powerpc64#25449e73 Avoid emitting a PT_INTERP section for powerpc64 kernels and arrange forthe first instruction to be at the start of the text segment.
