[Xen-devel] [PATCH v4 04/21] arm/acpi: Move end_boot_allocator after acpi_boot_table_init

[Shannon Zhao <zhaoshenglong@xxxxxxxxxx>]

From: Shannon Zhao <shannon.zhao@xxxxxxxxxx>

If ACPI is initialized after the boot allocator has ended(the system
state is not early boot), assert happens in acpi_os_zalloc_memory and
acpi_boot_table_init will fail. So it needs to move end_boot_allocator
after acpi_boot_table_init.
