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
