[Kernel-packages] [Bug 1564470] Re: Unable to install NI-VISA nikal kernel module because of GPL-only symbol 'pgprot_writecombine'

It's neither a Ubuntu bug, nor a upstream one. Instead it's entirely NI's fault: they're using an GPL-only symbol (which IIRC always has been GPL-only!) in their proprietary kernel driver. (the idea of binary-only kernel drivers alone is quite insane in the first place). The only serious fix is

Dear Ingo Molnar! I have a problem with *EXPORT_SYMBOL_GPL(pgprot_writecombine)* with Linux 4.4.0.16 on Ubuntu 16.04. The *pgprot_writecombine* symbol is used in NI_VISA nikal driver (see forwarded bugreport ). Is it safe to change
