Sorry to say this but the above is MOST annoying! :-(

If I am wrong in my assumptions then please forgive me.

I can only assume that your response to Masaru was to a private message 
between yourselves, but your response (above) was then also sent to this 
list.

I have checked the archives for March and April and there is nothing 
from you, Malte, with the above Thread Subject - and there is no reply 
from Masaru giving the full patch.

(I have tried to apply this "patch" to another driver and got back the 
response, "patch: **** Only garbage was found in the patch input.")

If you are going to provide a response to something which may be of 
importance to many people then please quote in FULL the most salient 
part of the advice you received from Masaru (ie, the full text of the 
patch).



Having stated the above I want to advice you, and anyone else, that last 
night I downloaded the latest nVidia driver - 331.67 - from nVidia and 
compiled it for the 3.14.x kernel using dkms.

It was a 'normal' install for driver 331.67 and kernel 3.14.0-2 using, 
"sh NVIDIA*.run --dkms" which compiled the driver without a hiccup.


@ Masaru:

At the beginning of this month (3 April) I asked if there was a patch to 
compile the 331.49 driver for the 3.14.x kernel and you provided the 
patch to be able to do so.

Before asking my question I had looked at the nVidia's forum site to see 
whether there was such a patch but couldn't see any information. But 
then you came up with the full info. of a patch.

My question now is: where do YOU find this information and where should 
I look to find information about the latest patch(s) when an nVidia 
driver fails to compile either normally or when using dkms?

Would be most grateful for this information (as nVidia is becoming a 
real pain in the arse for producing drivers which have to patched in 
order to compile with the [latest] kernels - and seeing as how dkms may 
also fail to keep up with the latest changes).
