This sounds like something that will always be wrong -- or in other
words, always be right for only the latest CPUs. Can this be made
dynamic, based on some timing factor?
In fact I think this has been tweaked twice in the vanilla tree
already.

Whenever jiffies is started at a multiple of 5*HZ or wraps, calc_load is
run exactly on the second which is when tasks using round_jiffies will
be scheduled to run. This has a bad effect on the load average, making
it tend towards 1.00 if a task happens to run every time the load is
being
This patch kills the "ignoring return value of 'device_create_file'"

The following patch series adds a device driver which allows an mtd
flash device to be used as a swap device. Since flash needs wear
levelling, a normal block device can't be used directly.
In order to work efficiently, some changes to other parts of Linux are
needed. Most of these changes are
Pass an optional struct page * to swap_free(), fixing up all users.
Have swap_free check the page for errors and if found, mark the swap
page as bad.

Check for pages with errors within shrink_page_list() and if found, try
to unuse them which will trigger the functions to mark the page bad. The
page will then be allocated a new swap page.
If a swap page write error occurs, don't disable page reclaim.

Hi,
Currently MMCONFIG is ignored if it is located over 4G, but I see no reason
to reject it on x86_64 platform.
This patch is against 2.6.21-rc2 and was tested on
such a machine (MMCONFIG is located at 0xfe1000)
without any problem.
Any comments?

The DSDT code clearly can't touch the hardware itself - hardware access
