           Summary: ACPI dynamic tables are not shown correctly --
                    bisected
           Product: ACPI
           Version: 2.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Config-Tables
        AssignedTo: rui.zhang at intel.com
        ReportedBy: rui.zhang at intel.com
                CC: acpi-bugzilla at lists.sourceforge.net
        Regression: No


ACPI dynamic tables are not shown in /sys/firmware/acpi/tables/dynamic, but in
/sys/firmware/acpi/tables/ instead.
This is introduced by commit:

78f1699659963fff97975df44db6d5dbe7218e55

    ACPI: processor: call _PDC early

because dynamic SSDT tables may be loaded in _PDC,
before installing the ACPI table handler.

we should invoke acpi_sysfs_init() before acpi_early_processor_set_pdc(),
so that the table handler is installed before any dynamic tables loaded.
