in memcpy, src and dest are overlaped.
for default implementaion or some architectures, it is OK.
but we can not be sure that it is OK for all platforms.
and in this condition, the performance are not quite important.
so better to use standard ways: let memmove instead of memcpy.
In function audit_alloc_context(), use kzalloc, instead of kmalloc+memset.
Patch also renames audit_zero_context() to
audit_set_context(), to represent it's inner workings properly.

I'm rebasing this patchset against latest linux-next, and it conflicts with

This patch fixes build failure of v3.9-rc5.
When config ACPI_VIDEO as m, DRM_GMA500 as y, here comes the failure.
gma5/600 needs acpi_video just like nouveau.
Failure message:

I'm rebasing this patchset against latest linux-next, and it conflicts with

That is a debugging patch and will never be pushed into mainline, so should I

better to check its parameters by itself.

Now the concern is how to deal with this issue,
I was wondering if there is a policy (formal or informal) for avoiding pursuing
such endeavors and if not, what would be the advice for a modern approach to
implement it for a current or future line of kernels.
