I am kind of lost trying to figure out how can kmallocs work if they are called before kmem_cache_init

(e.g. such a case occurs when in start_kernel() we call parse_early_param() (which in turn might call early_serial8250_setup() if earlycon= is used in kernel command-line) before mm_init()  (which later calls kmem_cache_init() )

I don't think that you're allowed to call kmalloc during early_setup. I don't see where early_serial8250_setup calls kmalloc. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com
