-Again we set `rdi` to a pointer to the `boot_params` structure and preserve it on the stack. In the same time we set `rsi` to point to the area which should be usedd for kernel uncompression. The last step is preparation of the `extract_kernel` parameters and call of this function which will uncompres the kernel. The `extract_kernel` function is defined in the  [arch/x86/boot/compressed/misc.c](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/compressed/misc.c) source code file and takes six arguments:
