- Build the kernel without the fix
- Add some flag to the purgatories KBUILD_CFLAGS,I used
-fno-asynchronous-unwind-tables
- Re-build the kernel
When you look at makes output you see that sha256.o is not re-build in the
last step. Also readelf -S still shows the .eh_frame section for
sha256.o.
With the fix sha256.o is rebuilt in the last step.
Without FORCE make does not detect changes only made to the command line
options. So object files might not be re-built even when they should be.
Fix this by adding FORCE where it is missing.
