deb-pkg: Inhibit initramfs builders if CONFIG_BLK_DEV_INITRD is not set

The kernel postinst hook for initramfs-tools will build an initramfs
on installation unless $INITRD is set to 'No'.  make-kpkg generates a
postinst script that sets this variable appropriately, but we don't.
Set it based on CONFIG_BLK_DEV_INITRD.

This should also work with dracut when <http://bugs.debian.org/729622>
is fixed.

Merge commit v3.13-rc1 into kbuild/misc
scripts: Coccinelle script for pm_runtime_* return checks with IS_ERR_VALUE

As indicated by Sekhar in [1], there seems to be a tendency to use
IS_ERR_VALUE to check the error result for pm_runtime_* functions which
make no sense considering commit c48cd65 (ARM: OMAP: use consistent
error checking) - the error values can either be < 0 for error OR
0, 1 in cases where we have success.

So, setup a coccinelle script to help identify the same.

deb-pkg: Fix cross-building linux-headers package

builddeb generates a control file that says the linux-headers package
can only be built for the build system primary architecture.  This
breaks cross-building configurations.  We should use $debarch for this
instead.

Since $debarch is not yet set when generating the control file, set
Architecture: any and use control file variables to fill in the
description.

deb-pkg: Fix building for MIPS big-endian or ARM OABI

These commands will mysteriously fail:

$ make ARCH=arm versatile_defconfig
[...]
$ make ARCH=arm deb-pkg
[...]
make[1]: *** [deb-pkg] Error 1
make: *** [deb-pkg] Error 2

The Debian architecture selection for these kernel architectures does
'grep FOO=y $KCONFIG_CONFIG && echo bar', and after 'set -e' this
aborts the script if grep does not find the given config symbol.

We also pass tcon as an argument to the function. This is already
available in the calling functions and we can avoid having to make an
unnecessary lookup.

cifs: Add support for follow_link on dfs shares under posix extensions

When using posix extensions, dfs shares in the dfs root show up as
symlinks resulting in userland tools such as 'ls' calling readlink() on
these shares. Since these are dfs shares, we end up returning -EREMOTE.

$ ls -l /mnt
ls: cannot read symbolic link /mnt/test: Object is remote
total 0
lrwxrwxrwx. 1 root root 19 Nov  6 09:47 test

With added follow_link() support for dfs shares, when using unix
extensions, we call GET_DFS_REFERRAL to obtain the DFS referral and
return the first node returned.

The dfs share in the dfs root is now displayed in the following manner.
$ ls -l /mnt
total 0
lrwxrwxrwx. 1 root root 19 Nov  6 09:47 test -> \vm140-31\test

Staging: rtl8812ae: Add Realtek 8821 PCI WIFI driver

This comes directly from the Realtek tarball, filename:
	wifi_driver_8821ae_0018.1129.2013.tar.gz

I mushed the three modules (btcoexist, rtlwifi and rtl8821ae) together
into one, in order to make it all build as one stand-alone module.
After the btcoexist driver gets merged upstream, I'll pull it out of
here, and will continue to work on removing this version of rtlwifi in
order to use the in-kernel one.
