#     crypto: lib - remove unneeded selection of XOR_BLOCKS
#     
#     CRYPTO_LIB_CHACHA_GENERIC doesn't need to select XOR_BLOCKS.  It perhaps
#     was thought that it's needed for __crypto_xor, but that's not the case.
#     
#     Enabling XOR_BLOCKS is problematic because the XOR_BLOCKS code runs a
#     benchmark when it is initialized.  That causes a boot time regression on
#     systems that didn't have it enabled before.
#     
#     Therefore, remove this unnecessary and problematic selection.
#     
#     Fixes: e56e18985596 ("lib/crypto: add prompts back to crypto libraries")
