Since SYSCALL/SYSRET rely on MSRs to control their function, split out syscall_enable() into syscall_initialize() and syscall_enable(), the latter being called on all CPUs. This affects not just syscalls but also the kernel_to_user_trampoline. Additionally, do away with the max syscalls, and just make a single page of syscall pointers and name pointers. Max syscalls was fragile and needed to be kept in sync in multiple places.
