The supplied script takes a vmlinux file - and if necessary a System.map
file - locates the system certificates list and extracts it to the named
file.
Call as:
./scripts/extract-sys-certs vmlinux certs
if vmlinux contains symbols and:
./scripts/extract-sys-certs -s System.map vmlinux certs
if it does not.
It prints something like the following to stdout:
Have 27 sections
No symbols in vmlinux, trying System.map
Have 80088 symbols
Have 1346 bytes of certs at VMA 0xffffffff8201c540
Certificate list in section .init.data
Certificate list at file offset 0x141c540
If vmlinux contains symbols then that is used rather than System.map - even
if one is given.
