commit 11a62a05 turns some formerly nopped debugging printks in arch/x86/kernel/mppparse.c into regular ones. The one at the top of smp_scan_config() in particular also prints on !CONFIG_SMP/CONFIG_X86_LOCAL_APIC kernels and UP machines without anything resembling MP tables which makes their lowly UP owners wonder... Turn the former Dprintk()s into apic_printk()s instead meaning that their printing is dependent on passing the apic=verbose (or =debug) command line param. On 32-bit, "apic" is a __setup() param which isn't early enough for this code and therefore needs a followup changing it into an early_param(). On 64-bit, it already is.

x2apic support. Interrupt-remapping must be enabled before enabling x2apic, this is needed to ensure that IO interrupts continue to work properly after the cpu mode is changed to x2apic(which uses 32bit extended physical/cluster apic id). On systems where apicid's are > 255, BIOS can handover the control to OS in x2apic mode. Or if the OS handover was in legacy xapic mode, check if it is capable of x2apic mode. And if we succeed in enabling Interrupt-remapping, then we can enable x2apic mode in the CPU.

This patch adds a 'flags' parameter to reserve_bootmem_generic() like it already has been added in reserve_bootmem() with commit 72a7fe39. It also changes all users to use BOOTMEM_DEFAULT, which doesn't effectively change the behaviour. Since the change is x86-specific, I don't think it's necessary to add a new API for migration. There are only 4 users of that function. The change is necessary for the next patch, using reserve_bootmem_generic() for crashkernel reservation.
