Shutemov" <kirill.shutemov@...ux.intel.com> Subject: [PATCHv4 12/14] x86/acpi: Rename fields in acpi_madt_multiproc_wakeup structure To prepare for the addition of support for MADT wakeup structure version 1, it is necessary to provide more appropriate names for the fields in the structure. The field 'mailbox_version' renamed as 'version'. This field signifies the version of the structure and the related protocols, rather than the version of the mailbox. This field has not been utilized in the code thus far. The field 'base_address' renamed as 'mailbox_address' to clarify the kind of address it represents. In version 1, the structure includes the reset vector address. Clear and distinct naming helps to prevent any confusion. Signed-off-by: Kirill A.
