From fb7c2bae8a479e388a1f664e32d6ddca55c7a249 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 24 May 2016 15:35:43 -0700 Subject: ACPI / processor: Add acpi_map_madt_entry() Follow-on arm64 ACPI/NUMA patches need to map MADT entries very early (before kmalloc is usable). Add acpi_map_madt_entry() which, indirectly, uses early_memremap()/early_memunmap() to access the table and parse out the mpidr. The existing implementation of map_madt_entry() is modified to take a pointer to the MADT as a parameter and the callers adjusted.
