From 6630cbce7cd7785f76b1055f33a71199ef28510b Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Fri, 14 Jun 2024 12:58:59 +0300 Subject: [PATCH] x86/acpi: Rename fields in the acpi_madt_multiproc_wakeup structure In order to support MADT wakeup structure version 1, provide more appropriate names for the fields in the structure. Rename 'mailbox_version' to '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. Rename 'base_address' to '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.
