with changes from mainline commit 6798a8caaf
"fs/seq_file: convert int seq_vprint/seq_printf/etc...
returns to void".

This reverts commit 5c7566a29b.
This patch revert some changes in net/netfilter/xt_qtaguid.c as well.
I'll submit another patch to restore those changes.

This reverts commit 8d3a6c1538.
This series of patches revert AOSP UID_STAT and NET_ACTIVITY_STATS drivers.
I could not find any meaningful usage of these interfaces in AOSP master.
UID_STAT driver expose "/proc/uid_stat/*" interfaces but it is only
used in AOSP master as in what appears be an out of date bandwidth
test in frameworks/base and in somewhat recent battery utils test
in external/chromium-trace project.
NET_ACTIVITY_STATS driver expose "/proc/net/stat/activity" interface
but I can not track its usage anywhere in AOSP at all.

Drivers should use extcon moving forward.
Documentation/extcon/porting-android-switch-class describes
how to port existing switch class drivers to extcon.
This reverts commit e4b8e66e0a.

IP_NF_TARGET_{MASQUERADE,NETMAP,REDIRECT} configs,
already enabled in android-base.cfg for tethering,
are of no use if CONFIG_IP_NF_NAT is not enabled.
Don't rely on platform config for that and enable
CONFIG_IP_NF_NAT in android-base.cfg as well.

Backport notes:
Backport uses kernel_module_from_file not kernel_read_file hook.
kernel_read_file replaced kernel_module_from_file in the 4.6 kernel.
There are no inode_security_() helper functions (also introduced in
4.6) so the inode lookup is done using the file_inode() helper which
is standard for kernel version < 4.6.
(Cherry picked from commit 61d612ea731e57dc510472fb746b55cdc017f371)
Utilize existing kernel_read_file hook on kernel module load.
Add module_load permission to the system class.
Enforces restrictions on kernel module origin when calling the
finit_module syscall. The hook checks that source type has
permission module_load for the target type.
Example for finit_module:
allow foo bar_file:system module_load;
Similarly restrictions are enforced on kernel module loading when
calling the init_module syscall. The hook checks that source
type has permission module_load with itself as the target object
because the kernel module is sourced from the calling process.
Example for init_module:
allow foo foo:system module_load;

Switch to the generic extable search and sort routines which were introduced
with commit a272858 from Ard Biesheuvel. This saves quite some memory in the
vmlinux binary with the 64bit kernel.
