2009-04-07ACPI: convert acpi_device_lock spinlock to mutexShaohua Li
Convert acpi_device_lock to a mutex to avoid a potential race upon access to /proc/acpi/wakeup Delete the lock entirely in wakeup.c since it is not necessary (and can not sleep) Found-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-03-27ACPI: call acpi_wakeup_device_init() explicitly rather than as initcallBjorn Helgaas
This patch makes acpi_init() call acpi_wakeup_device_init() directly. Previously, acpi_wakeup_device_init() was a late_initcall (sequence 7). acpi_wakeup_device_init() depends on acpi_wakeup_device_list, which is populated when ACPI devices are enumerated by acpi_init() -> acpi_scan_init(). Using late_initcall is certainly enough to make sure acpi_wakeup_device_list is populated, but it is more than necessary. We can just as easily call acpi_wakeup_device_init() directly from acpi_init(), which avoids the initcall magic.

2009-03-17ACPI: move private declarations to internal.hBjorn Helgaas
A number of things that shouldn't be exposed outside the ACPI core were declared in include/acpi/acpi_drivers.h, where anybody can see them. This patch moves those declarations to a new "internal.h" inside drivers/acpi. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
