This was used to make all ioctl handlers return -errno on linux and errno on
*BSD.  Instead, just return -errno in shared code, and flip sign on return f
shared code to *BSD code.

This code is ported from the DRM git tree and allows the vblank interrupts
to function on the i965 hw. It also requires a change in Mesa's 965 driver
to actually use them.

This 965G and above chipsets moved the batch buffer non-secure bits to
another place. This means that previous drm's allowed in-secure batchbuffers
to be submitted to the hardware from non-privileged users who are logged
into X and and have access to direct rendering.

Commit 9b01bd5b introduced a
compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was
to handle the fact that on i386, alignof(uint64_t)==4.

Unfortunately, this handler was installed for _all_ 64-bit
architectures, instead of only x86_64 and ia64.  And thus it breaks
32-bit compatibility on every other arch, where 64-bit integers are
aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode.

Arnd has a cunning plan to use 'compat_u64' with appropriate alignment
attributes according to the 32-bit ABI, but for now let's just make the
compat_radeon_cp_setparam routine entirely disappear on 64-bit machines
whose 32-bit compat support isn't for i386.  It would be a no-op with
compat_u64 anyway.
