Replace the hardcoded list of initialization functions for each CPU vendor by a list in an ELF section, which is read at initialization in arch/x86/kernel/cpu/cpu.c to fill the cpu_devs[] array. The ELF section, named .x86cpuvendor.init, is reclaimed after boot, and contains entries of type "struct cpu_vendor_dev" which associates a vendor number with a pointer to a "struct cpu_dev" structure. This first modification allows to remove all the VENDOR_init_cpu() functions. This patch also removes the hardcoded calls to early_init_amd() and early_init_intel(). Instead, we add a "c_early_init" member to the cpu_dev structure, which is then called if not NULL by the generic CPU initialization code. Unfortunately, in early_cpu_detect(), this_cpu is not yet set, so we have to use the cpu_devs[] array directly. This patch is part of the Linux Tiny project, and is needed for further patch that will allow to disable compilation of unused CPU support code.
