- Enables module for some common 10/40G NICs
from Broadcom, Intel, and Mellanox
- Enable KVM and related modules
These are targeted to support more bare metal
configuration with LinuxKit.

The original kernel Dockerfile hardcodes the amd64 as the
only arch supported, this patch removes this kind of hardcode
and make the Dockerfile is ready to support both amd64 and
arm64 by using the runtime arch type.

Otherwise files which have an updated timestamp but no actual changes are
marked as changes because `git diff-index` only uses the `lstat` result and not
the actual file contents. Running `git update-index --refresh` updates the
cache.

The definition of `$(TAG)` differs from pkg/package.mk and is only the
HASH+DIRTY since the full tag is defined by the kernel macro and varies for
each kernel.
Also `show-tag` is `show-tags` here due to the multiple builds. Individual
`show-tag_FOO` rules are provided similar to the `build_FOO` rules.

- Combine 'sign' and 'push' targets like it is done for
package builds.
- Append '-dirty' to the tag if the repository is dirty.
- Don't push to hub if the repository is dirty.

Module loading on hotplug and boot seems to work now, so
move some less commonly used kernel features and drivers
out of the kernel into drivers. Specifically:
- Devices: All non-virtual network device drivers
- Networking: GRE, GENEVE, PPP, non-essential IPv6 protos,
L2TP, MPLS_GSO, bonding, IPSec (XFRM), openvswitch,
queueing/schedulers
- FS: SUNRPC, NFS, NFSD, LOCKD, NTFS
- Misc: ATA over Ethernet
Remove Nozomi serial driver. It doesn't seem to be used
on any of our platforms.
The config files were also run through 'make defconfig &&
make oldconfig' to update any missing options.

It clashes with libelf-dev but libelf-dev is sufficient
to compile the kernel. This also allows us to remove the
'|| true' from the 'apk add', catching errors with the
tools installation.

Extract the perf binary from the kernel package and create
a new perf package for each kernel. The perf package uses the
same tags as the kernel package and only contains the perf
binary under /usr/bin. The perf package can be added to the
init section or included as a stage in a multi-stage build
for other packages.

The perf utility is somewhat kernel specific so might as well
compile it when we compile the kernel. The resulting binary
is statically linked (and stripped for size) and is added the
resulting kernel packages.
Although we add alpine packages such as libunwind and other,
it seems that the config detection code for perf/tools does
not detect them.

This cherry-picks 120010cb1eea151d38a3e66f5ffc79a0c3110292 ("tools build:
Add test for sched_getcpu()") which replaces a #ifdef based test with
a proper test for the sched_getcpu() function. The macro based condition
does not work on Alpine as it is conditional on GLIBC.
For 4.9 the cherry-pick needed some manual adjustment and also required
commit ef2c3e76d98dfb69a46d870b47656e8e5bac6e2b ("perf jit: Avoid returning
garbage for a ret variable")

For local testinf it is useful to store packages under a different
organisation on the hub (or indeed to select a different registry).
This is enabled by making the ORG configurable when calling make.
