Dear kernel devs,
After configuring for 2 hours settings, faced below on making :
cc1: error:
/usr/src/linux-next-master/arch/x86/crypto/serpent-sse2-x86_64-asm_64.S:
Input/output error
Thank you for your attantion to config matter last days, It is really
physically hard every time sort sort out menu again. If it would
ppossible to have standard -- Conservative Unix style secure / paranoid
choice alongwith -- allyesconfig .
Thank you !
