arm:
drivers/char/drm/drm_lock.c: In function `drm_lock_take':
drivers/char/drm/drm_lock.c:221: error: implicit declaration of function `cmpxchg'
You might be able to use atomic_cmpxchg, which _is_ present
on all architectures. Or use a spinlock.
What's that code doing anyway? driver-private locking primitives?
When did arm suddenly start wanting DRM? they need to grow a userpsace
cmpxchg as davem mentioned to go along with this, changing the drm now
isn't possible due to backwards compat..
Dave.
