| * | | ACPI: Cache battery status instead of re-evaluating AMLVladimir Lebedev2007-03-071-172/+441
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | /proc exports _BST in a single file, and _BST is re-evaulated whenever that file is read. Sometimes user-space reads this file frequently, and on some systems _BST takes a long time to evaluate due to a slow EC. Further, when we move to sysfs, the values returned from _BST will be in multiple files, and evaluating _BST for each file read would make matters worse. Here code is added to support caching the results of _BST. A new module parameter "update_time" tells how many seconds the cached _BST should be used before it is re-evaluated. Currently, update_time defaults to 0, and so the existing behaviour of re-evaluating on each read retained.

Function trace is most of the ACPI_DEBUG costs, but is not much of use for kernel ACPI debugging. Size of kernel image increased on test compile: + 48k (Full ACPI_DEBUG) + 35k (ACPI_DEBUG with function trace compiled out) Performance without function trace is also much better. Also remove ACPI_LV_DEBUG_OBJECT from default debug level as a lot vendors let Store (value, debug) in their code and this might confuse users when it pops up in syslog.

The problem with __ndelay has been tacked down to the rounding of the multiplier constant. By changing this, delays > app 18us are correctly calculated. The problem with __udelay has also been tracked down to rounding issues. Changing the multiplier constant (to match that used in sparc64) corrects for large delays and adding in a rounding constant corrects for trunctaion errors in the claculations. Many short delays will return without looping. This is not an error as there is the fixed delay of doing all the maths to calculate the loop count.

* | | | | | | i386: fix iounmap's use of vm_struct's size fieldJeremy Fitzhardinge2007-07-212-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_vm_area always returns an area with an adjacent guard page. That guard page is included in vm_struct.size. iounmap uses vm_struct.size to determine how much address space needs to have change_page_attr applied to it, which will BUG if applied to the guard page. This patch adds a helper function - get_vm_area_size() in linux/vmalloc.h - to return the actual size of a vm area, and uses it to make iounmap do the right thing. There are probably other places which should be using get_vm_area_size(). Thanks to Dave Young <hidave.darkstar@gmail.com> for debugging the problem.

Move it to the pit header file, so it can be used by x86_64 as well. Move also the PIT constants.
