From e5b6d55a6e5e13002cf79a42a0b78b3188e88a1f Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Fri, 24 Sep 2021 08:27:44 -0400 Subject: acpi: use build_append_int_noprefix() API to compose SRAT table Drop usage of packed structures and explicit endian conversions when building SRAT tables for arm/x86 and use endian agnostic build_append_int_noprefix() API to build it.
