these warnings: arch/x86/kernel/paravirt-spinlocks.c: In function ‘default_spin_lock_flags’: arch/x86/kernel/paravirt-spinlocks.c:12: warning: passing argument 1 of ‘__raw_spin_lock’ from incompatible pointer type arch/x86/kernel/paravirt-spinlocks.c: At top level: arch/x86/kernel/paravirt-spinlocks.c:11: warning: ‘default_spin_lock_flags’ defined but not used showed that the prototype of default_spin_lock_flags() was confused about what type spinlocks have. the proper type on UP is raw_spinlock_t.
