Note: This is a resend due to my prior messages being word-wrapped accidentally.
Apologies for the duplicates!

With increasing interest in non-x86 architectures (e.g. ARM64, POWER8),
there is a growing desire to execute legacy x86 applications that cannot
be recompiled on these new architectures.

This series enables 3D multimedia applications (e.g. games) to function
correctly on an emulated x86_64 host in user mode.  It resolves several
issues noted within the x86_64 user mode, and adds 3D ioctls for Intel
and AMD graphics.  Furthermore, it adds ALSA sound ioctls.

NOTE: The initial DRM ioctl patch was taken from the qemu mailing list:

Aaditya Chandrasekhar Azad (1):
  This patch adds initial user-virtualization support for the DRM (type 
       'd') IOCTLs in linux. With it and a corresponding architecture
    chroot     (say aarch64), I am able to successfully run a few 2D and
    3D     applications with native graphics acceleration. Some
    notes/caveats     are:

Timothy Pearson (6):
  Add initial x86_64 signal handlers
  QEMU does not currently support host pages that are larger than    
    guest pages, likely due to glibc using fixed mmap requests.
  Pass select() arguments directly to do_select() on x86 platforms
  TIOCGPTN and related terminal control ioctls were not converted to
    the guest ioctl format on x86_64 targets.  Convert these ioctls    
    to enable terminal functionality on x86_64 guests.
  Add radeon DRM interface ioctls
  Add ALSA ioctls
