Hi Scott,

I love your patch! Perhaps something to improve:

^^^^^^^^^^^^^^^^^^^

Sorry, you asked me about this earlier. You will need to add
-D__CHECK_ENDIAN__ to enable these Sparse warnings.
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__'
