The kernel parses parameters from the kernel command line up to “–”; if it doesn’t recognize a parameter and it doesn’t contain a ‘.’, the parameter gets passed to init: parameters with ‘=’ go into init’s environment, others are passed as command line arguments to init. This is handy if debugging and you need to use tracing_snapshot() on boot up, and do not want to use tracing_snapshot_alloc() as it needs to be done where GFP_KERNEL allocations are allowed.
Everything after “–” is passed as an argument to init. DRM Direct Rendering Management support is enabled. amd_iommu= [HW, X86-64] Pass parameters to the AMD IOMMU driver in the system.

This will happen only on 64 bit systems, the cause is the fact that 32 bit libraries are missing from the system, so you can easily fix this issue by installing the 32 bit libraries on your system.
The distribution's kernel is normally a "vanilla" kernel, with many patches on top of it that either did not get accepted to the "vanilla" kernel, or that the distribution's maker back-ported from newer kernels.
