Fix a memcpy that should be a text_poke (in apply_alternatives). Use kernel_wp_save/kernel_wp_restore in text_poke to support DEBUG_RODATA correctly and so the CPU HOTPLUG special case can be removed. Add text_poke_early, for alternatives and paravirt boot-time and module load time patching. Changelog: - Fix text_set and text_poke alignment check (mixed up bitwise and and or) - Remove text_set - Export add_nops, so it can be used by others. - Document text_poke_early. - Remove clflush, since it breaks some VIA architectures and is not strictly necessary. - Add kerneldoc to text_poke and text_poke_early. - Create a second vmap instead of using the WP bit to support Xen and VMI. - Move local_irq disable within text_poke and text_poke_early to be able to be sleepable in these functions.

for system with apicid lifting, boot cpu apicid will be 4 got: CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line) CPU: L2 Cache: 512K (64 bytes/line) CPU 0/4 -> Node 0 CPU: Physical Processor ID: 1 CPU: Processor Core ID: 0 so try to offset apicid back before get phys_proc_id with bits shift. then we can get correct socket ID also remove remove cpu_data(0) reference. because cpu_data(0) only be ready after smp_prepare_cpus with the assignment from boot_cpu_data to current_cpu_data aka cpu_data(0). and check_bugs()==>identify_cpu(&boot_cpu_data) is quite before than smp_prepare_cpus. So just use boot_cpu_id instead. Signed-off-by:

Glauber Costa authored
setup_trampoline() looks very similar between architectures, and this patch unifies them. The i386 version allocates bootmem memory, while the x86_64 version uses a fixed address. In this patch, we initialize the global trampoline_base to the x86_64 version, and i386 allocation can later override it. Signed-off-by:
