Subject: [PATCHES] uaccess i915

	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()
