That is, the alternative() in UNTRAIN_RET # will patch in the CALL to srso_alias_untrain_ret() directly. # # However, even if commit e7c25c441e9e ("x86/cpu: Cleanup the untrain # mess") meant well in trying to clean up the situation, due to micro- # architectural reasons, the untraining routine srso_alias_untrain_ret() # must be the target of a CALL instruction and not of a JMP instruction as # it is done now. # # Reshuffle the alternative macros to accomplish that. # # Fixes: e7c25c441e9e ("x86/cpu: Cleanup the untrain mess") # Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> # Reviewed-by: Ingo Molnar <mingo@kernel.org> # Cc: stable@kernel.org # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 4535e1a4174c4111d92c5a9a21e542d232e0fcaa # make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- g5_defconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/linus_g5_defconfig_powerpc-gcc11 # Build took: 0:04:06.730253
