2011-11-11ACPI: Fix CONFIG_ACPI_DOCK=n compiler warningBart Van Assche
commit c1056b42a87b59375f8f81a92ef029165f44fcce upstream. Recently the ACPI ops structs were constified but the inline version of register_hotplug_dock_device() was overlooked (see also commit 9c8b04b, June 25 2011). Update the inline function register_hotplug_dock_device() that is enabled with CONFIG_ACPI_DOCK=n too. This patch fixes at least the following compiler warnings: drivers/ata/libata-acpi.c: In function .ata_acpi_associate.: drivers/ata/libata-acpi.c:266:11: warning: passing argument 2 of .register_hotplug_dock_device. discards qualifiers from pointer target type include/acpi/acpi_drivers.h:146:19: note: expected .struct acpi_dock_ops *. but argument is of type .const struct acpi_dock_ops *. drivers/ata/libata-acpi.c:275:11: warning: passing argument 2 of .register_hotplug_dock_device. discards qualifiers from pointer target type include/acpi/acpi_drivers.h:146:19: note: expected .struct acpi_dock_ops *. but argument is of type .const struct acpi_dock_ops *.

2011-07-13ACPI: Fix lockdep false positives in acpi_power_off()Rafael J. Wysocki
All ACPICA locks are allocated by the same function, acpi_os_create_lock(), with the help of a local variable called "lock". Thus, when lockdep is enabled, it uses "lock" as the name of all those locks and regards them as instances of the same lock, which causes it to report possible locking problems with them when there aren't any. To work around this problem, define acpi_os_create_lock() as a macro and make it pass its argument to spin_lock_init(), so that lockdep uses it as the name of the new lock. Define this macron in a Linux-specific file, to minimize the resulting modifications of the OS-independent ACPICA parts. This change is based on an earlier patch from Andrea Righi and it addresses a regression from 2.6.39 tracked as https://bugzilla.kernel.org/show_bug.cgi?id=38152 Signed-off-by: Rafael J.

2011-05-29ACPI: Add D3 cold stateLin Ming
_SxW returns an Integer containing the lowest D-state supported in state Sx. If OSPM has not indicated that it supports _PR3, then the value “3” corresponds to D3. If it has indicated _PR3 support, the value “3” represents D3hot and the value “4” represents D3cold. Linux does set _OSC._PR3, so we should fix it to expect that _SxW can return 4.

2011-05-29ACPI: processor: fix processor_physically_present in UP kernelLin Ming
Usually, there are multiple processors defined in ACPI table, for example Scope (_PR) { Processor (CPU0, 0x00, 0x00000410, 0x06) {} Processor (CPU1, 0x01, 0x00000410, 0x06) {} Processor (CPU2, 0x02, 0x00000410, 0x06) {} Processor (CPU3, 0x03, 0x00000410, 0x06) {} } processor_physically_present(...) will be called to check whether those processors are physically present. Currently we have below codes in processor_physically_present, cpuid = acpi_get_cpuid(...); if ((cpuid == -1) && (num_possible_cpus() > 1)) return false; return true; In UP kernel, acpi_get_cpuid(...) always return -1 and num_possible_cpus() always return 1, so processor_physically_present(...) always returns true for all passed in processor handles. This is wrong for UP processor or SMP processor running UP kernel. This patch removes the !SMP version of acpi_get_cpuid(), so both UP and SMP kernel use the same acpi_get_cpuid function. And for UP kernel, only processor 0 is valid. https://bugzilla.kernel.org/show_bug.cgi?id=16548 https://bugzilla.kernel.org/show_bug.cgi?id=16357 Tested-by: Anton Kochkov <anton.kochkov@gmail.com> Tested-by: Ambroz Bizjak <ambrop7@gmail.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2011-03-21ACPI, APEI, Add ERST record ID cacheHuang Ying
APEI ERST firmware interface and implementation has no multiple users in mind. For example, if there is four records in storage with ID: 1, 2, 3 and 4, if two ERST readers enumerate the records via GET_NEXT_RECORD_ID as follow, reader 1 reader 2 1 2 3 4 -1 -1 where -1 signals there is no more record ID. Reader 1 has no chance to check record 2 and 4, while reader 2 has no chance to check record 1 and 3. And any other GET_NEXT_RECORD_ID will return -1, that is, other readers will has no chance to check any record even they are not cleared by anyone. This makes raw GET_NEXT_RECORD_ID not suitable for used by multiple users. To solve the issue, an in-memory ERST record ID cache is designed and implemented. When enumerating record ID, the ID returned by GET_NEXT_RECORD_ID is added into cache in addition to be returned to caller. So other readers can check the cache to get all record ID available.

2011-02-24ACPI: Remove the wakeup.run_wake_count device fieldRafael J. Wysocki
The wakeup.run_wake_count ACPI device field is only used by the PCI runtime PM code to "protect" devices from being prepared for generating wakeup signals more than once in a row. However, it really doesn't provide any protection, because (1) all of the functions it is supposed to protect use their own reference counters effectively ensuring that the device will be set up for generating wakeup signals just once and (2) the PCI runtime PM code uses wakeup.run_wake_count in a racy way, since nothing prevents acpi_dev_run_wake() from being called concurrently from two different threads for the same device. Remove the wakeup.run_wake_count ACPI device field which is unnecessary, confusing and used in a wrong way. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
