CONFIG_USELIB seems misplaced here, very few architectures can even
call that, and it's not in the asm-generic/unistd.h file.

relay is selected by drivers that need it, you should not need to turn
it on here.
> +CONFIG_SYSCTL_SYSCALL=y
Also not in the asm-generic syscall table. We should probably hide the
CONFIG_USELIB and CONFIG_SYSCTL_SYSCALL options so they
only appear on architectures that can use them (patches welcome).
> +CONFIG_KALLSYMS_ALL=y
While useful for debugging, this is also something I would not expect
in the defconfig file
> +CONFIG_USERFAULTFD=y
Probably not needed either, unless you have a specific use
case.
> +CONFIG_EMBEDDED=y
This (and CONFIG_EXPERT) is mostly there to expose options
that are otherwise hidden for good reasons. Is there any option
you tweak that depends on this? If not, then remove this as well.
> +CONFIG_PROFILING=y
This is only for oprofile, which new architectures should generally
no longer implement. Better implement PERF only.
> +CONFIG_BLK_DEV_INTEGRITY=y
This is also fairly unusual.

Better enable only EXT4 and drop EXT2/EXT3.
> +CONFIG_UNUSED_SYMBOLS=y
You should only need this to work around bugs, so
I'd turn it off.
