Merge branches 'acpi-scan', 'acpi-bus', 'acpi-tables' and 'acpi-sysfs'
Merge ACPI changes related to device enumeration, device object managenet, operation region handling, table parsing and sysfs interface: - Use ZERO_PAGE(0) instead of empty_zero_page in the ACPI device enumeration code (Giulio Benetti). - Change the return type of the ACPI driver remove callback to void and update its users accordingly (Dawei Li). - Add general support for FFH address space type and implement the low- level part of it for ARM64 (Sudeep Holla). - Fix stale comments in the ACPI tables parsing code and make it print more messages related to MADT (Hanjun Guo, Huacai Chen). - Replace invocations of generic library functions with more kernel- specific counterparts in the ACPI sysfs interface (Christophe JAILLET, Xu Panda). * acpi-scan: ACPI: scan: substitute empty_zero_page with helper ZERO_PAGE(0) * acpi-bus: ACPI: FFH: Silence missing prototype warnings ACPI: make remove callback of ACPI driver void ACPI: bus: Fix the _OSC capability check for FFH OpRegion arm64: Add architecture specific ACPI FFH Opregion callbacks ACPI: Implement a generic FFH Opregion handler * acpi-tables: ACPI: tables: Fix the stale comments for acpi_locate_initial_tables() ACPI: tables: Print CORE_PIC information when MADT is parsed * acpi-sysfs: ACPI: sysfs: use sysfs_emit() to instead of scnprintf() ACPI: sysfs: Use kstrtobool() instead of strtobool()
