* ACPI: thermal: expose "thermal.tzp=" to set global polling frequencyLen Brown2007-08-122-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thermal Zone Polling frequency (_TZP) is an optional ACPI object recommending the rate that the OS should poll the associated thermal zone. If _TZP is 0, no polling should be used. If _TZP is non-zero, then the platform recommends that the OS poll the thermal zone at the specified rate. The minimum period is 30 seconds. The maximum period is 5 minutes. (note _TZP and thermal.tzp units are in deci-seconds, so _TZP = 300 corresponds to 30 seconds) If _TZP is not present, ACPI 3.0b recommends that the thermal zone be polled at an "OS provided default frequency". However, common industry practice is: 1. The BIOS never specifies any _TZP 2. High volume OS's from this century never poll any thermal zones Ie. The OS depends on the platform's ability to provoke thermal events when necessary, and the "OS provided default frequency" is "never":-) There is a proposal that ACPI 4.0 be updated to reflect common industry practice -- ie. no _TZP, no polling. The Linux kernel already follows this practice -- thermal zones are not polled unless _TZP is present and non-zero. But thermal zone polling is useful as a workaround for systems which have ACPI thermal control, but have an issue preventing thermal events. Indeed, some Linux distributions still set a non-zero thermal polling frequency for this reason. But rather than ask the user to write a polling frequency into all the /proc/acpi/thermal_zone/*/polling_frequency files, here we simply document and expose the already existing module parameter to do the same at system level, to simplify debugging those broken platforms. Note that thermal.tzp is a module-load time parameter only. Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: thermal: create "thermal.off=1" to disable ACPI thermal supportLen Brown2007-08-122-1/+11
| | | | | | | | | | | | | | "thermal.off=1" disables all ACPI thermal support at boot time. CONFIG_ACPI_THERMAL=n can do this at build time. "# rmmod thermal" can do this at run time, as long as thermal is built as a module. WARNING: On some systems, disabling ACPI thermal support will cause the system to run hotter and reduce the lifetime of the hardware. Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My "slices" address space management code that was added in the 2.6.22 implementation of get_unmapped_area() doesn't properly check that the size is a multiple of the requested page size. This allows userland to create VMAs that aren't a multiple of the huge page size with hugetlbfs (since hugetlbfs entirely relies on get_unmapped_area() to do that checking) which leads to a kernel BUG() when such areas are torn down.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | powerpc has a couple of bugs in the usage of dma_masks that tend to break when drivers explicitly try to set a 32-bit mask for example. First, the code that generates the pci devices from the OF device-tree doesn't initialize the mask properly, then our implementation of set_dma_mask() was trying to validate the -previous- mask value, not the one passed in as an argument. This fixes these problems. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* | | | i386: Fix double fault handlerChuck Ebbert2007-08-111-6/+7

Doublefault is handled by a hardware task, making the check SPIN_BUG_ON(lock->owner == current, lock, "recursion"); fault because it uses the FS register to access the percpu data for current, and that register is zero in the new TSS. (The trace I saw was on 2.6.20 where it was GS, but it looks like this will still happen with FS on 2.6.22.) Initializing FS in the doublefault_tss should fix it.
