| * dock: introduce .uevent for devices in dock, eg libataShaohua Li2008-09-23
| | | | | | | | | | | | | | | | | | | | | | dock's uevent reported itself, not ata. It might be difficult to find an ata device just according to a dock. This patch introduces docking ops for each device in a dock. when docking, dock driver can send device specific uevent. This should help dock station too (not just bay) Signed-off-by: Shaohua Li <shaohua.li@intel.com> Acked-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com>
| * ACPI: fix hotplug raceZhang Rui2008-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hotplug notification handler and drivers' notification handler all run in one workqueue. Before hotplug removes an acpi device, the device driver's notification handler is already be recorded to run just after global notification handler. After hotplug notification handler runs, acpica will notice a NULL notification handler and crash. So now we run run hotplug in another workqueue and wait for all acpi notication handlers finish. This was found in battery hotplug, but actually all hotplug can be affected.

For example: the bios returns D0 state and the real power state is D3. OS expects to set the device to D0 state. In such case if OS uses the power state returned by the BIOS and checks the device power state very strictly in power transition, the device can't be transited to the correct power state. So the boot option of "acpi.power_nocheck=1" is added to avoid checking the device power in the course of device power transition. http://bugzilla.kernel.org/show_bug.cgi?id=8049 http://bugzilla.kernel.org/show_bug.cgi?id=11000 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Li Shaohua <shaohua.li@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

It currently is doing that in userspace which results in: - Huge test scripts that could be a one liner in the kernel - A lot of BIOS bugs are already absorbed by the kernel What do we need such a stupid linuxfirmwarekit for? - Vendors: Can test their BIOSes for Linux compatibility. There will be the time when vendors realize that the test utils on Linux are more strict and using them increases the qualitity and stability of their products. - Vendors: Can easily fix up their BIOSes and be more Linux compatible by: dmesg |grep "Firmware Bug" and send the result to their BIOS developer colleagues who should know what the messages are about and how to fix them, without the need of studying kernel code. - Distributions: can do a first automated HW/BIOS checks. This can then be done without the need of asking kernel developers who need to dig down the code and explain the details. Certification can/will just be rejected until dmesg |grep "Firmware Bug" is empty. - Thus this can be used as an instrument to enforce cleaner BIOS code. Currently every stupid Windows ACPI bug is re-implemented in Linux which is a rather unfortunate situation. We already have the power to avoid this in e.g. memory or cpu hot-plug ACPI implementations, because Linux certification is a must for most vendors in the server area. Working towards being able to do that in the laptop area (vendors are starting to look at Linux here also and will use this tool) is the goal. At least provide them a tool to make it as easy for this guys (e.g. not needing to browse kernel code) as possible. - The ordinary Linux user: can go into the next shop, boots the firmwarekit on his most preferred machines. He chooses one without BIOS bugs. Unsupported HW is ok, he likes to try out latest projects which might support them or likes to dig on it on his own, but he hates to workaround broken BIOSes like hell. I double checked with the firmwarekit. There they have: So the mapping generally is (also depending on how likely the BIOS is to blame, this could sometimes be difficult): FW_INFO = INFO FW_WARN = WARN FW_BUG = FAIL For more info about the linuxfirmwarekit and why this is needed can be found here: http://www.linuxfirmwarekit.org While severity matches with the firmwarekit, it might be tricky to hide messages from the user. E.g. we recently found out that on HP BIOSes negative temperatures are returned, which seem to indicate that the thermal zone is invalid. We can work around that gracefully by ignoring the thermal zone and we do not want to bother the ordinary user with a frightening message: Firmware Bug: thermal management absolutely broken but want to hide it from the user. But in the linuxfirmwarekit this should be shown as a real show stopper (the temperatures could really be wrong, broken thermal management is one of the worst things that can happen and the BIOS guys of the machine must implement this properly). It is intended to do that (hide it from the user with KERN_INFO msg, but still print it as a BIOS bug) by: printk(KERN_INFO FW_BUG "Negativ temperature values detected. Try to workarounded, BIOS must get fixed\n"); Hope that works out..., no idea how to better hide it as printk is the only way to easily provide this functionality.

However do_truncate is what caused the lock ordering error, due to it taking i_mutex. In this case, we can actually just call ramfs directly to allocate memory for the mapping, rather than go via truncate.

| * | [MIPS] Fixe the definition of PTRS_PER_PGDJack Tan2008-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we use > 4KB's page size the original definition is not consistent with PGDIR_SIZE. For exeample, if we use 16KB page size the PGDIR_SHIFT is (14-2) + 14 = 26, PGDIR_SIZE is 2^26，so the PTRS_PER_PGD should be: 2^32/2^26 = 2^6 but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0). So, this definition needs to be consistent with the PGDIR_SIZE. And the new definition is consistent with the PGD init in pagetable_init().

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 9p trans modules aren't refcounted nor were they unregistered properly. Fix it. * Add 9p_trans_module->owner and reference the module on each trans instance creation and put it on destruction. * Protect v9fs_trans_list with a spinlock. This isn't strictly necessary as the list is manipulated only during module loading / unloading but it's a good idea to make the API safe. * Unregister trans modules when the corresponding module is being unloaded. * While at it, kill unnecessary EXPORT_SYMBOL on p9_trans_fd_init().
