Adding a new architecture pops up time to time, since the answer remains
the same each time, provide the common question/answer in the FAQ.

Previously OOT-module builds used `--sourcedir` to specify oot-module
source directory which was a bit confusing and also denied users ability
to build kpatches agains oot modules built against non-distro kernels.
This patch adds `-p/--oot-module-src` option to specify source dir for
oot module while keeping `--sourcedir` for kernel source directory
specification.
I also tried to disambiguate `SRCDIR` in kpatch-build a bit. Now there
are 3 variables:
- `KERNEL_SRCDIR` - contains path to kernel source directory
- `OOT_MODULEL_SRCDIR` - contains path to out-of-tree module source directory
- `BUILDDIR` - can be set to either of the above and is used for
patch-related actions
Another attempt at this was done by @omatiusha in #1234

A bash script is available to automatically install necessary
dependencies for building/using kpatch on some distributions.
Update the README sections for those distributions to use that script.

ccache version in epel updates from time to time so instead of
using a direct link install epel repo and install ccache without
specifying the version.

Run the input patch(es) through lsdiff and then verify that no obviously
unsupported files are directly modified (e.g. assembly .S files).

For consistency, use the long format command line options in the
description and sample invocation. Also, use "--oot-module" and not
"--out-of-tree" as per kpatch-build sources.

On Ubuntu Trusty, HWE kernels don't come with a linux-source
package. Use dget to retrieve the source package instead. This is not
the case anymore with Xenial as the linux-source package is also
provided for the HWE kernels. For Debian, backports always come with the
linux-source package.
* remove the Fedora release number
* add part of the $(uname -r) to kernel package specifications
* add patchutils as an optional package to satisfy kpatch-test
* update to the latest ccache rpm URL @ dl.fedoraproject.org
"kpatch replace" is complex, buggy, and probably unnecessary. And
upstream livepatch has nothing like it.
Remove it from the kpatch utility, but leave the infrastructure in place
in the patch module and the core module for now.
Fixes: #456
Change the supported Fedora version to F21 and add a new dependency.
For some reason, numactl-devel is needed by "rpmbuild -bp kernel", but
isn't detected by "yum-builddep kernel".
