Hi All,
Within the security folder in the kernel tree, the
2.6.20 linux kernel distribution is shipped with a
file root_plug.c (written by Greg Kroah-Hartman),
which is a classic introduction to Linux Security
Modules (LSM). The folder also contains the folder of
SELinux.

i386: Convert to quicklists
Implement the i386 management of pgd and pmds using quicklists.
The i386 management of page table pages currently uses page sized slabs.
The page state is therefore mainly determined by the slab code. However,
i386 also uses its own fields in the page struct to mark sp

I have tested on my mac mini g4.
The 2.6.21-rc2 will cause oops like the above post.

Subject: Simplify smp_call_function*() by using common implementation
smp_call_function and smp_call_function_single are almost complete
duplicates of the same logic. This patch combines them by

See arch/powerpc/kernel/sysfs.c:topology_init. I don't think there is
anything to do here. You probably don't have CONFIG_HOTPLUG_CPU enabled.
