This is strange. I ran the sparse build and thought I had fixed all
the issues.
I'll have to try again.
One other question with the sparse build. I get many of the messages
printed but the build seems to go to the end (even without my patches
applied):
./arch/x86/include/asm/paravirt.h:333:9: error: got __inline
./arch/x86/include/asm/paravirt.h:338:9: error: Expected ( after asm
./arch/x86/include/asm/paravirt.h:338:9: error: got __inline
./arch/x86/include/asm/paravirt.h:343:9: error: Expected ( after asm
./arch/x86/include/asm/paravirt.h:343:9: error: got __inline
./arch/x86/include/asm/paravirt.h:348:9: error: Expected ( after asm
./arch/x86/include/asm/paravirt.h:348:9: error: too many errors
Any way to suppress or I am doing something wrong? I just run the 2
make commands:
make ARCH=x86_64 allmodconfig
make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
I figured out
the sparse utility on ubuntu 18.04 is out of date causing
the issue.
