Why do you expect a different result? Also, calling exit from a vforked child is explicitly not allowed. The only things you can do are execve or _exit. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/ --

The ds18b20 one wire temperature sensor conversion routine is returning the units in degrees C while the ds1820 (ds18s20) is returning it in .001 degrees C. 20C vs 20312C. Once you know the units I'm liking the latter as it gives a higher precision. Time to break user applications so the driver can give the temperature in the same units for both sensors. I only have the ds18b20 sensor model. Here is the current output from the sys file for this sensor. /sys/devices/w1_bus_master1/28-0000000e84...

I am preparing to convert the boot time page table to the kernels native format. To achieve that I need to enable PAE. Enabling PSE and the no execute bit would not hurt.

The struct module taints member is supposed to store per-module taint data. The kernel knows about certain specific external modules that will taint the kernel, such as ndiswrapper. Use of ndiswrapper possibly should set the per-module taint in addition to the global kernel taint flag, unless we're arguing not because wrapper module itself is not what actually causes the kernel to be tainted as such?

Sorry, I should have made it clearer that this was more for discussion of the actual formatting. printk_address needs to be ported to X86_32, the one in this patch is just a placeholder. Looking at the X86_64 version it looks like it can be brought straight across, but I haven't tested that yet. Harvey --
