From: Ard Biesheuvel Date: Tue, 2 Jul 2019 19:41:45 +0000 (+0200) Subject: crypto: aes-generic - unexport last-round AES tables X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1e25ca02a0619c10bc0eae975846926902381ce5;p=linux.git crypto: aes-generic - unexport last-round AES tables The versions of the AES lookup tables that are only used during the last round are never used outside of the driver, so there is no need to export their symbols.
