During final testing, when building the kernel with an initramfs, I hit
the following linker error:

LD .tmp_vmlinux1
arch/riscv/kernel/head.o: in function `.L0 ':(.init.text+0x5c): relocation truncated to fit: R_RISCV_JAL against `.Lsecondary_park'
make[1]: *** [Makefile:1079: vmlinux] Error 1
make: *** [Makefile:326: __build_one_by_one] Error 2

Could you take a look at this?


thanks,
