ACPI: x86: Call acpi_boot_table_init() after acpi_table_upgrade()
commit6998a8800d
upstream. Commit1a1c130ab7
("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. Fixes:1a1c130ab7
