I don't have /etc/sysconfig/grub on Manjaro. Is it /etc/default/grub?
Should I add the line as specified in the article if my CPU is as old as Core 2 Duo? Will it make any difference? Won't it render the system unbootable?

grep . /sys/devices/system/cpu/vulnerabilities/*
And yes, you'll need to edit the /etc/default/grub file, but make sure that you add your extra parameters to GRUB_CMDLINE_LINUX_DEFAULT based on this:GRUB_CMDLINE_LINUX_DEFAULT="noresume noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off mitigations=off"
