Hi,

I tried to compile but the x86/smap.h header is missing, can you share with me?

Best regards,

Hello,

 you can find my messy patch here [1]. If you don't have CPU that supports
SMAP/SMEP then consider debugging under qemu which works fine.

 TODO:

 - investigate if we can get rid of all those clac/stac in patch.c
 - turn off smap/smep for XEN (or evaluate what needs to be done in that
   manner)
 - TNF style compiance
 - audit STAC/CLAC usage in copy.S

 Feel free to do whatever you want, but don't forget to let me know about
it! :-)

 Kind Regards,
 Mateusz Kocielski
