Several implicit unsigned --> signed int conversions were corrected.
No runtime effects were observed here, nevertheless implicit conversions

Currently the created tc actions list is reversed against the order
set by the user.
Change the actions list order to be the same as was set by the user.
This patch doesn't affect dump actions behavior.
For dumping, action->order parameter is used so the list order doesn't
matter.

Jiri Pirko says:
====================
fib offload: switch to notifier
The goal of this patchset is to allow driver to propagate all prefixes
configured in kernel down HW. This is necessary for routing to work
as expected. If we don't do that HW might forward prefixes known to kernel
incorrectly. Take an example when default route is set in switch HW and there
is an IP address set on a management (non-switch) port.
Currently, only FIB entries related to the switch port netdev are
offloaded using switchdev ops. This model is not extendable so the
first patch introduces a replacement: notifier to propagate FIB entry
additions and removals to whoever is interested.
The second patch introduces couple of helpers to deal with RTNH_F_OFFLOAD
flags. Currently it is set in switchdev core. There the assumption is
that only one offload device exists. But for FIB notifier, we assume
multiple offload devices. So the patch introduces a per FIB entry
reference counter and helpers use it in order to achieve this:
0 means RTNH_F_OFFLOAD is not set, no device offloads this entry
n means RTNH_F_OFFLOAD is set and the entry is offloaded by n devices
Patches 3 and 4 convert mlxsw and rocker to adopt this new way, registering
one notifier block for each asic instance. Both of these patches also
implement internal "abort" mechanism.
Using switchdev ops, "abort" is called by switchdev core whenever there is
an error during FIB entry add offload. This leads to removal of all
offloaded entries on system by fib_trie code.
Now the new notifier assumes the driver takes care of the abort action.
Here's why:
1) The fact that one HW cannot offload an entry does not mean that the
others can't do it. So let only one entity to abort and leave the rest
to work happily.
2) The driver knows what to in order to properly abort. For example,
currently abort is broken for mlxsw, as for Spectrum there is a need
to set 0.0.0.0/0 trap in RALUE register.
The fifth patch removes the old, no longer used FIB offload infrastructure.
The last patch reflects the changes into switchdev documentation file.

Until now, in order to offload a FIB entry to HW we use switchdev op.
However that has limits. Mainly in case we need to make the HW aware of
all route prefixes configured in kernel. HW needs to know those in order
to properly trap appropriate packets and pass the to kernel to do
the forwarding. Abort mechanism is now handled within the mlxsw driver.

An "unnecessary" 'else' was removed due to complains from checkpatch.pl
as it is preceded by a 'return', however the 'else' branch is necessary
as an earlier branch of the 'if' falls through. By removing the 'else',
that route now hits the 'break' and the 'while' loop exits prematurely.
This commit reverts that change and puts the original 'else' back in
place.

This patch adds an option to use XZ compression for the kernel image.
Currently this is only enabled for 64-bit Book3S targets, which is
roughly equivalent to the platforms that use the kernel's zImage
wrapper, and that have been tested.
The bulk of the 32-bit platforms and 64-bit BookE use uboot images,
which relies on uboot implementing XZ. In future we can enable XZ
support for those targets once someone has tested it.

This modifies the wrapper script so that the -Z option takes an argument
to specify the compression type. It can either be 'gz', 'xz' or 'none'.
The legazy --no-gzip and -z options are still supported and will set the
compression to none and gzip respectively, but they are not documented.
Only XZ -6 is used for compression rather than XZ -9. Using compression
levels higher than 6 requires the decompressor to build a large (64MB)
dictionary when decompressing and some environments cannot satisfy such
large allocations (e.g. POWER 6 LPAR partition firmware).

handle decompressing gzipped kernels. The kernel decompressor library
functions now provide a generic interface that can be used in the

this new API, but does not add support for using new algorithms.

The powerpc boot wrapper is potentially compiled with a separate
toolchain and/or toolchain flags than the rest of the kernel. The usual
case is a 64-bit big endian kernel builds a 32-bit big endian wrapper.
The main problem with this is that the wrapper does not have access to
the kernel headers (without a lot of gross hacks). To get around this
the required headers are copied into the build directory via several sed
scripts which rewrite problematic includes. This patch moves these
fixups out of the makefile into a separate .sed script file to clean up
makefile slightly.
