Hi Linus, Please pull from the tag git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ acpi-5.9-rc1 with top-most commit db1da2f52ea5477e917957dd80c1da63affa60e6 Merge branches 'acpi-mm', 'acpi-tables', 'acpi-apei' and 'acpi-misc' on top of commit 92ed301919932f777713b9172e525674157e983d Linux 5.8-rc7 to receive ACPI updates for 5.9-rc1. These eliminate significant AML processing overhead related to using operation regions in system memory, update the ACPICA code in the kernel to upstream revision 20200717 (including a fix to prevent operation region reference counts from overflowing in some cases), remove the last bits of the (long deprecated) ACPI procfs interface and do some assorted cleanups. Specifics: - Eliminate significant AML processing overhead related to using operation regions in system memory by reworking the management of memory mappings in the ACPI code to defer unmap operations (to do them outside of the ACPICA locks, among other things) and making the memory operation reagion handler avoid releasing memory mappings created by it too early (Rafael Wysocki). - Update the ACPICA code in the kernel to upstream revision 20200717: * Prevent operation region reference counts from overflowing in some cases (Erik Kaneda). * Replace one-element array with flexible-array (Gustavo A. R. Silva). - Fix ACPI PCI hotplug reference counting (Rafael Wysocki). - Drop last bits of the ACPI procfs interface (Thomas Renninger). - Drop some redundant checks from the code parsing ACPI tables related to NUMA (Hanjun Guo). - Avoid redundant object evaluation in the ACPI device properties handling code (Heikki Krogerus). - Avoid unecessary memory overhead related to storing the signatures of the ACPI tables recognized by the kernel (Ard Biesheuvel). - Add missing newline characters when printing module parameter values in some places (Xiongfeng Wang). - Update the link to the ACPI specifications in some places (Tiezhu Yang). - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R. Silva). - Drop redundant variable initialization from the APEI code (Colin Ian King). - Drop uninitialized_var() from the ACPI PAD driver (Jason Yan). - Replace HTTP links with HTTPS ones in the ACPI code (Alexander A. Klimov). Thanks! --------------- Alexander A.
