Jon Masters 38b04a74c5 ACPI: ARM64: support for ACPI_TABLE_UPGRADE ... This patch adds support for ACPI_TABLE_UPGRADE for ARM64 To access initrd image we need to move initialization of linear mapping a bit earlier. The implementation of the feature acpi_table_upgrade() (drivers/acpi/tables.c) works with initrd data represented as an array in virtual memory. It uses some library utility to find the redefined tables in that array and iterates over it to copy the data to new allocated memory. So to access the initrd data via fixmap we need to rewrite it considerably. In x86 arch, kernel memory is already mapped by the time when acpi_table_upgrade() and acpi_boot_table_init() are called so I think that we can just move this mapping one function earlier too.
