Dear Linux folks,
Fetching the commits from Linus’ tree, and doing `make olddefconfig`,
the build failed:

Please find the full problematic config file attached.
Selecting `CONFIG_CRYPTO_LIB_POLY1305=m` works around the issue.

I didn’t bisect, but commit 8bdc2a190105 (crypto: poly1305 - cleanup
stray CRYPTO_LIB_POLY1305_RSIZE) jumps out for example.
Kind regards,
