Every EXPORT_SYMBOL creates __kstrtab_* and __kstrtabns_*, which
consumes 15-20% of the kallsyms entries.
For example, on the system built from the x86_64 defconfig,
$ cat /proc/kallsyms | wc
129527 388581 5685465
$ cat /proc/kallsyms | grep __kstrtab | wc
23489 70467 1187932
We already ignore __crc_* symbols populated by EXPORT_SYMBOL, so it
should be fine to ignore __kstrtab_* and __kstrtabns_* as well.
This makes vmlinux a bit smaller.
