FreeBSD amd64 linker script
Hello,
When linking the FreeBSD amd64 kernel with lld it seems the LMA of some
sections is not correctly set, this is the output:
# readelf -l /boot/kernel/kernel
Elf file type is EXEC (Executable file)
Entry point 0xffffffff80331000
There are 10 program headers, starting at offset 64
