From 6915564dc5a8ab831a016e0cd0a8a3c68230287b Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 11 Sep 2020 14:59:35 +0200 Subject: ACPI: OSL: Change the type of acpi_os_map_generic_address() return value Modify acpi_os_map_generic_address() to return the pointer returned by acpi_os_map_iomem() which represents the logical address corresponding to the struct acpi_generic_address argument passed to it or NULL if that address cannot be obtained (for example, the argument does not represent an address in system memory or it could not be mapped by the OS). Among other things, that will allow the ACPI OS layer to pass the logical addresses of the FADT GPE blocks 0 and 1 to ACPICA going forward. Signed-off-by: Rafael J.

The existing comments suggest this is intentional, but the usecases of this function are related to NFIT and HMAT parsing, neither of which should be able to define new nodes. One route by which the existing behaviour would cause a crash is to have a _PXM entry in ACPI DSDT attempt to place a device within this partly created proximity domain. A subsequent call to devm_kzalloc() or similar would result in an attempt to allocate memory on a node for which zone lists have not been set up and a NULL pointer dereference. Prevent such cases by switching to pxm_to_node() within acpi_map_pxm_to_online_node() which cannot cause a new node to be partly created. If one would previously have been created we now return NO_NUMA_NODE. Documentation updated to reflect this change. Signed-off-by: Jonathan Cameron Reviewed-by: Hanjun Guo Signed-off-by: Rafael J.
