Low-hanging fruit in i915 uaccess-related stuff.
There's some subtler stuff remaining after that; these
are the simple ones.
Branch in uaccess.i915, based at uaccess.base.
Al Viro (5):
i915: switch query_{topology,engine}_info() to copy_to_user()
i915: switch copy_perf_config_registers_or_number() to unsafe_put_user()
i915 compat ioctl(): just use drm_ioctl_kernel()
i915: alloc_oa_regs(): get rid of pointless access_ok()
i915:get_engines(): get rid of pointless access_ok()
