x86: process_64.c declare __switch_to() and sys_arch_prctl before they get used
Impact: cleanup In asm/system.h moved out __switch_to from CONFIG_X86_32 as it is common for both 32 and 64 bit. In asm/pctl.h defined sys_arch_prctl Signed-off-by: Jaswinder Singh <jaswinder@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
