Subject[PATCH 2/3] asm-generic: don't #include <linux/atomic.h> in qspinlock_types.h
Date
The "qspinlock_types.h" doesn't need linux/atomic.h directly. So
because of this, and because including of it requires the protection
against recursive inclusion, it looks reasonable to move the
inclusion exactly where it is needed. This change affects the x86_64
arch, as the only user of qspinlocks at now. I have build-tested the
change on x86_64 with CONFIG_PARAVIRT enabled and disabled.
