Pointers in kernel_args are going to be changed to unconditionally use 64-bit storage (to make kernel_args compatible with both the x86 and x86_64 kernels). KMessage stores a pointer to its buffer, however since KMessage is used outside of the boot code it is undesirable to change it to use 64-bit storage for the pointer as it may add additional overhead on 32-bit builds. Therefore, only store the buffer address and size and then construct a KMessage from those in the kernel.
