Seeing this error on SPARC while compiling qrwlock.c.
CC kernel/locking/qrwlock.o
In file included from ./include/asm-generic/qrwlock_types.h:5,
from ./arch/sparc/include/asm/qrwlock.h:4,
from kernel/locking/qrwlock.c:24:
./arch/sparc/include/asm/spinlock_types.h:5:3: error:
#error "please don't include this file directly"
Re-arrange the includes in qrwlock_types.h and also include spinlock.h
in qrwlock.c to fix it. This should also help other architectures when
queued rwlock is enabled.
