commit 6998a8800d73116187aad542391ce3b2dd0f9e30 upstream.
Commit 1a1c130ab757 ("ACPI: tables: x86: Reserve memory occupied by ACPI tables") attempted to address an issue with reserving the memory occupied by ACPI tables, but it broke the initrd-based table override mechanism relied on by multiple users.
To restore the initrd-based ACPI table override functionality, move the acpi_boot_table_init() invocation in setup_arch() on x86 after the acpi_table_upgrade() one.
