ACPI: APEI: explicit init of HEST and GHES in apci_init()
From commit e147133a42cb ("ACPI / APEI: Make hest.c manage the estatus memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage the estatus memory pool. On the other hand, ghes_init() relies on sdei_init() to detect the SDEI version and (un)register events. The dependencies are as follows: ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init() ghes_init() => sdei_init() HEST is not PCI-specific and initcall ordering is implicit and not well-defined within a level. Based on above, remove acpi_hest_init() from acpi_pci_root_init() and convert ghes_init() and sdei_init() from initcalls to explicit calls in the following order: acpi_hest_init() ghes_init() sdei_init() Signed-off-by: Shuai Xue <xueshuai@linux.alibaba.com> Signed-off-by: Rafael J.
