Hi Sergio,

Depending of the IDE developers use, the patch subject is not always prepended to the patch description.

You can add: "The following functions are named *pc* but are not PC-machine specific but generic to the X86 architecture, rename them:"

load_linux                 -> x86_load_linux
pc_new_cpu                 -> x86_new_cpu

Maybe we can rename this one 'x86_cpu_new'?

pc_cpus_init               -> x86_cpus_init
pc_cpu_index_to_props      -> x86_cpu_index_to_props
pc_get_default_cpu_node_id -> x86_get_default_cpu_node_id
pc_possible_cpu_arch_ids   -> x86_possible_cpu_arch_ids
old_pc_system_rom_init     -> x86_system_rom_init

This one as 'x86_bios_rom_init'?

Nit: Adding 2 spaces before each line would ease readability.
