Binary package hint: nvidia-173-kernel-source

Problem:

No matter what, whether I use the nvidia installer or attempt to 'make
module' under package source provided, the make attempt would exit with
an error at line 130 of os-interface.c.  I did some searching with Uncle
Google, and found a patch.  I applied the patch to version 173.14.16 of
the module source and it built with NO complaint and NO errors.  In
fact, its the ONLY way I got my nvidia card driver into the kernel with
no problems - all other attempts failed.

Solution, as follows: @os-interface.c:line 127-ish

change line 'spin_lock_init(&os_sema->lock);'

to

#ifdef CONFIG_PREEMPT_RT
        rt_spin_lock_init(&os_sema->lock);
#else
        spin_lock_init(&os_sema->lock);
#endif

... and voila, it will handle kernels built with varying preemption
configurations.

Here is the link to the original solution:

I urge you to patch the current 173.14.16 version immediately, and test
it for yourself.

Further:

I urge you to push this fix up-channel to nVidia itself as ALL
installers croak at the exact same point with the exact same problem on
your distro's kernel.  Also, I would like you to extract 173.14.20 from
the installer (or however you got the 173.14.16 source) and test the
patch with that version.  If it works: WILL YOU PLEASE UPDATE THIS
PACKAGE TO 173.14.20 with the patch and fixes?!?  -OR- email me with how
to extract the source from the installer and I'll build and test it
myself and report my findings back.  Seriously, once I got the error
message through my head it took 20 minutes to fix this problem, its not
that hard ... please maintain this critical package.

Thanks,

G. Gibson
