2006-11-23[PATCH] Correct bound checking from the value returned from _PPC method.Dave Jones
processor_perflib.c::acpi_processor_ppc_notifier() check if the value returned by the processor's _PPC method is 0 and return failed if so.

2006-11-22WorkStruct: Pass the work_struct pointer instead of context dataDavid Howells
Pass the work_struct pointer to the work function rather than context data. The work function can use container_of() to work out the data. For the cases where the container of the work_struct may go away the moment the pending bit is cleared, it is made possible to defer the release of the structure by deferring the clearing of the pending bit. To make this work, an extra flag is introduced into the management side of the work_struct. This governs auto-release of the structure upon execution. Ordinarily, the work queue executor would release the work_struct for further scheduling or deallocation by clearing the pending bit prior to jumping to the work function. This means that, unless the driver makes some guarantee itself that the work_struct won't go away, the work function may not access anything else in the work_struct or its container lest they be deallocated.. This is a problem if the auxiliary data is taken away (as done by the last patch). However, if the pending bit is *not* cleared before jumping to the work function, then the work function *may* access the work_struct and its container with no problems. But then the work function must itself release the work_struct by calling work_release(). In most cases, automatic release is fine, so this is the default. Special initiators exist for the non-auto-release case (ending in _NAR). Signed-Off-By: David Howells <dhowells@redhat.com>
2006-11-17Revert "ACPI: created a dedicated workqueue for notify() execution"Linus Torvalds
This reverts commit 37605a6900f6b4d886d995751fcfeef88c4e462c. Again. This same bug has now been introduced twice: it was done earlier by commit b8d35192c55fb055792ff0641408eaaec7c88988, only to be reverted last time in commit 72945b2b90a5554975b8f72673ab7139d232a121. We must NOT try to queue up notify handlers to another thread than the normal ACPI execution thread, because the notifications on some systems seem to just keep on accumulating until we run out of memory and/or threads. Keeping events within the one deferred execution thread automatically throttles the events properly. At least the Compaq N620c will lock up completely on the first thermal event without this patch reverted.

2006-11-09ACPI: button: register with input layerDmitry Torokhov
In addition to signalling button/lid events through /proc/acpi/event, create separate input devices and report KEY_POWER, KEY_SLEEP and SW_LID through input layer. Also remove unnecessary casts and variable initializations, clean up formatting. Sleep button may autorepeat but userspace will have to filter duplicate sleep requests anyway (and discard unprocessed events right after wakeup). Unlike /proc/acpi/event interface input device corresponding to LID switch reports true lid state instead of just a counter. SW_LID is active when lid is closed. The driver now depends on CONFIG_INPUT. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Len Brown <len.brown@intel.com>
2006-10-20[PATCH] acpi memory hotplug: remove strange add_memory fail messageYasunori Goto
I wrote a patch to avoid redundant memory hot-add call at boot time. This was cause of strange fail message of memory hotplug like "ACPI: add_memory failed". Memory is recognized by early boot code with EFI/E820. But, if DSDT describes memory devices for them, then hot-add code is called for already recognized memory, and it shows fail messages with -EEXIST. So, sys admin will misunderstand this message as something wrong by it. This patch avoids them by preventing redundant hot-add call until completion of driver initialization.

2006-10-20[PATCH] fix "ACPI: Processor native C-states using MWAIT"Darrick J. Wong
This patch breaks C-state discovery on my IBM IntelliStation Z30 because the return value of acpi_processor_get_power_info_fadt is not assigned to "result" in the case that acpi_processor_get_power_info_cst returns -ENODEV. Thus, if ACPI provides C-state data via the FADT and not _CST (as is the case on this machine), we incorrectly exit the function with -ENODEV after reading the FADT. The attached patch sets the value of result so that we don't exit early. Signed-off-by: Darrick J.
