x86: pre-initialize boot_cpu_data.x86_phys_bits to avoid system_state tests
Impact: cleanup, micro-optimization Pre-initialize boot_cpu_data.x86_phys_bits to a reasonable default to remove the use of system_state tests in __virt_addr_valid() and __phys_addr(). Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
