Subject: [PATCH v2 4/5] riscv: vmlinux.lds.S: explicitly catch .init.bss sections from EFI stub
Date:   Thu, 19 Jan 2023 23:54:16 +0800

When enabling linker orphan section warning, I got warnings similar as
below:
ld.lld: warning:
./drivers/firmware/efi/libstub/lib.a(efi-stub-helper.stub.o):(.init.bss)
is being placed in '.init.bss'

Catch the sections so that we can enable linker orphan section warning.
