Linux kernel modifications for the Kernel Hacking exam

Edward Cree says: ==================== sfc: driver for EF100 family NICs, part 1 EF100 is a new NIC architecture under development at Xilinx, based partly on existing Solarflare technology. As many of the hardware interfaces resemble EF10, support is implemented within the 'sfc' driver, which previous patch series "commonised" for this purpose. In order to maintain bisectability while splitting into patches of a reasonable size, I had to do a certain amount of back-and-forth with stubs for things that the common code may try to call, mainly because we can't do them until we've set up MCDI, but we can't set up MCDI without probing the event queues, at which point a lot of the common machinery becomes reachable from event handlers. Consequently, this first series doesn't get as far as actually sending and receiving packets. I have a second series ready to follow it which implements the datapath (and a few other things like ethtool). Changes from v4: * Fix build on CONFIG_RETPOLINE=n by using plain prototypes instead of INDIRECT_CALLABLE_DECLARE. Changes from v3: * combine both drivers (sfc_ef100 and sfc) into a single module, to make non-modular builds work. Patch #4 now adds a few indirections to support this; the ones in the RX and TX path use indirect-call- wrappers to minimise the performance impact. Changes from v2: * remove MODULE_VERSION. * call efx_destroy_reset_workqueue() from ef100_exit_module(). * correct uint32_ts to u32s. While I was at it, I fixed a bunch of other style issues in the function-control-window code. All in patch #4. Changes from v1: * kernel test robot spotted a link error when sfc_ef100 was built without mdio. It turns out the thing we were trying to link to was a bogus thing to do on anything but Falcon, so new patch #1 removes it from this driver. * fix undeclared symbols in patch #4 by shuffling around prototypes and #includes and adding 'static' where appropriate. * fix uninitialised variable 'rc2' in patch #7. ==================== Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
