[patch v11 00/23] Introduce ACPI for ARM64 based on ACPI 5.1

[Hanjun Guo]

Some fixes since last version:

 - Add a patch 19/23 for disabling ACPI for Xen on ARM64 for now to fix
   compile errors on XEN ACPI, Stefano and Julien are ok with this
   temporary solution.
 - Add patch "ARM64 / ACPI: Don't unflatten device tree if acpi=force 
   is passed", which will fix the problem that the device tree will
   be unflattened even if acpi=force passed, that will not obey the
   policy.
 - update patch "irqchip: Add GICv2 specific ACPI boot support",
   which will cause compile error on i386 with both DT and ACPI
   enabled:

   All error/warnings:

    In file included from include/linux/acpi_irq.h:4:0,
                     from drivers/irqchip/irqchip.c:11:
    arch/x86/include/asm/irq.h:35:8: error: unknown type name 'bool'
     extern bool handle_irq(unsigned irq, struct pt_regs *regs);
            ^
    arch/x86/include/asm/irq.h:35:45: warning: 'struct pt_regs' declared 
    inside parameter list
     extern bool handle_irq(unsigned irq, struct pt_regs *regs);
                                                 ^
    arch/x86/include/asm/irq.h:35:45: warning: its scope is only this 
    definition or declaration, which is probably not what you want
    ....

   That's because of I include the <asm/irq.h> in <linux/acpi_irq.h>,
   and <linux/acpi_irq.h> will be put on the top of all head files,
   so use <linux/irq.h> instead of <asm/irq.h> in acpi_irq.h (in
   <linux/irq.h>, it will include <linux/*.h> before include
   <asm/irq.h>), this is the only update for this patch.

Lorenzo will send some cleanup patches on top of this one soon.

Thanks
Hanjun
