For the most part, these changes match what glibc does.

4d8fe5177e Tune the memcpy for krait. 
Streamline the memcpy a bit removing some unnecessary instructions.

The biggest speed improvement comes from changing the size of
the preload. On krait, the sweet spot for the preload in the main
loop is twice the L1 cache line size.

In most cases, these small tweaks yield > 1000MB/s speed ups. As
the size of the memcpy approaches about 1MB, the speed improvement
disappears.

1aae9bd170 strncpy: implement _FORTIFY_SOURCE=2 
Add support for fortify source level 2 to strncpy.
This will enable detection of more areas where strncpy
is used inappropriately. For example, this would have detected
bug 8727221.

Move the fortify_source tests out of string_test.cpp, and
put it into fortify1_test.cpp.

Create a new fortify2_test.cpp file, which copies all
the tests in fortify1_test.cpp, and adds fortify_source level
2 specific tests.

e66ad7809e [NETFILTER]: Fix iptables ABI breakage 
Pick up Linux kernel patch 2748e5dec7ca8a3804852c7c4171f9156384d15c
from 2007

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2748e5dec7ca8a3804852c7c4171f9156384d15c

[NETFILTER]: Fix iptables ABI breakage on (at least) CRIS
With the introduction of x_tables we accidentally broke compatibility
by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of
XT_TABLE_MAXNAMELEN, which is two bytes larger.

On most architectures it doesn't really matter since we don't have
any tables with names that long in the kernel and the structure
layout didn't change because of alignment requirements of following
members. On CRIS however (and other architectures that don't align
data) this changed the structure layout and thus broke compatibility
with old iptables binaries.

Changing it back will break compatibility with binaries compiled
against recent kernels again, but since the breakage has only been
there for three releases this seems like the better choice.
