Hi All,
I am very sorry, and it is my mistake for sending this patchset to
linux-kernel mailing list. Please don't look at this one.

The maximum number of mmio handlers that are allowed is limited to
a macro MAX_IO_HANDLER(16), which is not enough for supporting per CPU
Redistributor regions. We need at least MAX_IO_HANDLER+CONFIG_NR_CPUS
mmio handlers in order to support ACPI based XEN boot.
This patchset uses the dynamic allocation strategy to allocate memory
resource dynamically depends on the number of Redistributor regions
that are described in the APCI MADT table.

arm/io: Use separate memory allocation for mmio handlers
xen: Add generic implementation of binary search
xen/arm: io: Use binary search for mmio handler lookup
arm/vgic: Change fixed number of mmio handlers to variable number
