From 626b901f60446355e35e8c76c6b391a7d7491203 Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Fri, 14 Aug 2020 12:45:04 -0700 Subject: Drivers: hv: vmbus: Add parsing of VMbus interrupt in ACPI DSDT On ARM64, Hyper-V now specifies the interrupt to be used by VMbus in the ACPI DSDT. This information is not used on x86 because the interrupt vector must be hardcoded. But update the generic VMbus driver to do the parsing and pass the information to the architecture specific code that sets up the Linux IRQ. Update consumers of the interrupt to get it from an architecture specific function.
