Add handling for ZBB extension and add support for using it as a
variant for optimized string functions.

Support for the Zbb-str-variants is limited to the GNU-assembler
for now, as LLVM has not yet acquired the functionality to
selectively change the arch option in assembler code.
This is still under review at

Depending on supported extensions on specific RISC-V cores,
optimized str* functions might make sense.

This adds basic infrastructure to allow patching the function calls
via alternatives later on.

The Linux kernel provides standard implementations for string functions
but when architectures want to extend them, they need to provide their
own.

The added generic string functions are done in assembler (taken from
disassembling the main-kernel functions for now) to allow us to control
the used registers and extend them with optimized variants.

This doesn't override the compiler's use of builtin replacements. So still
first of all the compiler will select if a builtin will be better suitable
i.e. for known strings. For all regular cases we will want to later
select possible optimized variants and in the worst case fall back to the
generic implemention added with this change.

This cleans up the ISA string handling to more closely match a version
of the ISA spec.  This is visible in /proc/cpuinfo and the ordering
changes may break something in userspace, but these orderings have
changed before without issues so with any luck that's still the case.

This also adds documentation so userspace has a better idea of what is
intended when it comes to compatibility for /proc/cpuinfo, which should
help everyone as this will likely keep changing.

The RISC-V specs are permissive in what they allow as the ISA string,

Ordering between each and every list of extensions is wildly
inconsistent. Per discussion on the lists pick the following policy:

- The array defining order in /proc/cpuinfo follows a narrow
  interpretation of the ISA specifications, described in a comment
  immediately presiding it.

- All other lists of extensions are sorted alphabetically.

This will hopefully allow for easier review & future additions, and
reduce conflicts between patchsets as the number of extensions grows.

While the current list of rules may have been accurate when created
it now lacks some clarity in the face of isa-manual updates. Instead of
trying to continuously align this rule-set with the one in the
specifications, change the role of this comment.

This particular comment is important, as the array it "decorates"
defines the order in which the ISA string appears to userspace in
/proc/cpuinfo.

Re-jig and strengthen the wording to provide contributors with a set
order in which to add entries & note why this particular struct needs
more attention than others.

While in the area, add some whitespace and tweak some wording for
readability's sake.

When adding the ARCH_ symbol for the builtin K210 dtb, I erroneously
used the bool type for something that is quite obviously a string.
Unfortunately, there is no such thing as "def_string", but in this case
we can use "default" to propagate the value of
SOC_CANAAN_K210_DTB_SOURCE to ARCH_CANAAN_K210_DTB_SOURCE.
ARCH_CANAAN_K210_DTB_SOURCE is not user selectable, so using
olddefconfig etc will update ARCH_CANAAN_K210_DTB_SOURCE to reflect any
changes made to SOC_CANAAN_K210_DTB_SOURCE.

From: Heiko Stuebner <heiko.stuebner@vrull.eu>

This series is split out of my work on optimizing string functions
and provides the basics to:

- actually allowing calls in alternatives
  Function calls use auipc + jalr to reach those 32bit relative
  addresses but when they're compiled the offset will be wrong
  as alternatives live in a different section. So when the patch
  gets applied the address will point to the wrong location.

  So similar to arm64 the target addresses need to be updated.

  This is probably also helpful for other things needing more
  complex code in alternatives.

For v2 I got into some sort of cleanup spree for the general instruction
parsing that already existed. A number of places do their own
instruction parsing and I tried consolidating some of them.

Noteable, the kvm parts still do, but I had to stop somewhere :-)

Used together U-type and I-type instructions can for example be used to
generate bigger jumps (i.e. in auipc+jalr pairs) by splitting the value
into an upper immediate (i.e. auipc) and a 12bit immediate (i.e. jalr).

Due to both immediates being considered signed this creates some corner
cases, so add some helper to prevent this from getting duplicated in
different places.

Similar to other existing types, allow extracting the immediate
for a U-type instruction.

U-type immediates are special in that regard, that the value
in the instruction in bits [31:12] already represents the same
bits of the immediate, so no shifting is required.

U-type immediates are for example used in the auipc instruction,
so these constants make it easier to parse such instructions.

Merge tag 'soc2arch-immutable' of git://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into for-next

SOC_FOO to ARCH_FOO conversion for RISC-V

RISC-V is an outlier in using SOC_FOO rather than ARCH_FOO for
vendors/micro-archs. SOC_FOO may make more sense (I personally prefer
it), but the rest of the "world" uses ARCH_FOO. That'd be fine, with
with an increasing number of existing SoC vendors moving to RISC-V,
unifying our symbol names with the expectations of the rest of the world
makes sense.
Folks did not seem keen on changing the world (and they can't really be
blamed for that) so convert RISC-V over to match.

Add some ARCH_FOO stubs alongside the existing SOC_FOO ones, which will
be removed once all users of SOC_FOO have been converted*, and convert
the DT bits of RISC-V kbuild over to the new symbols.

* It may be best to wait until after the next LTS to remove the SOC_FOO
  ones, for the sake of external users.

To me, the most straight-forward conversion looks like so:
- this patch is applied in week 2 of the merge window, to avoid
  any conflicts with the Renesas tree
- all users of the SOC_ variants can be converted over a release cycle
  (or more) & no trees need to merge an immutable branch.
- we convert defconfig etc over after all users are converted
- doing it over at least one release cycle means that `make oldconfig`
  will keep people's configs working as they upgrade
- any new SoC families added uses ARCH_FOO

SOC_SIFIVE so there is no need to directly select their symbols

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci

    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
