From e57d04e5fa00f7649d4c00796f8d12054799be4a Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sat, 24 Oct 2020 22:35:07 +0100 Subject: x86/apic: Get rid of apic:: Dest_logical struct apic has two members which store information about the destination mode: dest_logical and irq_dest_mode. dest_logical contains a mask which was historically used to set the destination mode in IPI messages. Over time the usage was reduced and the logical/physical functions were seperated. There are only a few places which still use 'dest_logical' but they can use 'irq_dest_mode' instead. irq_dest_mode is actually a boolean where 0 means physical destination mode and 1 means logical destination mode. Of course the name does not reflect the functionality. This will be cleaned up in a subsequent change. Remove apic::dest_logical and fixup the remaining users.
