Merge tag 'acpi-4.7-rc7' of git://
Pull ACPI fixes from Rafael Wysocki: "All of these fix recent regressions in ACPICA, in the ACPI PCI IRQ management code and in the ACPI AML debugger. Specifics: - Fix a lock ordering issue in ACPICA introduced by a recent commit that attempted to fix a deadlock in the dynamic table loading code which in turn appeared after changes related to the handling of module-level AML also made in this cycle (Lv Zheng). - Fix a recent regression in the ACPI IRQ management code that may cause PCI drivers to be unable to register an IRQ if that IRQ happens to be shared with a device on the ISA bus, like the parallel port, by reverting one commit entirely and restoring the previous behavior in two other places (Sinan Kaya). - Fix a recent regression in the ACPI AML debugger introduced by the commit that removed incorrect usage of IS_ERR_VALUE() from multiple places (Lv Zheng)" * tag 'acpi-4.7-rc7' of git:// ACPI / debugger: Fix regression introduced by IS_ERR_VALUE() removal ACPICA: Namespace: Fix namespace/interpreter lock ordering ACPI,PCI,IRQ: separate ISA penalty calculation Revert "ACPI, PCI, IRQ: remove redundant code in acpi_irq_penalty_init()" ACPI,PCI,IRQ: factor in PCI possible
