Following my kernel compilation issue i used another method to get the source.
I added :
# custom patch for acs override support
Patch6666: override_for_missing_acs_capabilities.patch

in my kernel.spec
The patch is in rpmbuild/SOURCES but when i run the build it says the file is missing.
Also to noted i wasn't able to apply the patch following documentation simply because it seems the patch application changed entirely ?
So either the patch listed is apply automatically with the other in the code or i need to find the proper place to apply it.
I posted below the command i use to build following by the error message, second paste is the sources i used.
It seems i'm really close to succeeding in the case the patch is workng, just have to solve this and i should have proper patch kernel
