Merge tag 'cfi-v5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull CFI on arm64 support from Kees Cook:
 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

  Summary:

   - Clean up list_sort prototypes (Sami Tolvanen)

   - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)"

Linus Torvalds 8900d92fd6 Staging/IIO driver updates for 5.13-rc1
Here is the big set of staging and IIO driver updates for 5.13-rc1.
 
 Lots of little churn in here, and some larger churn as well.  Major
 things are:
 	- removal of wimax drivers, no one has this hardware anymore for
 	  this failed "experiment".
 	- removal of the Google gasket driver, turns out no one wanted
 	  to maintain it or cares about it anymore, so they asked for it
 	  to be removed.
 	- comedi finally moves out of the staging directory into
 	  drivers/comedi/  This is one of the oldest kernel subsystems
 	  around, being created in the 2.0 kernel days, and was one of
 	  the first things added to drivers/staging/ when that was
 	  created over 15 years ago.  It should have been moved out of
 	  staging a long time ago, it's well maintained and used by
 	  loads of different devices in the real world every day.  Nice
 	  to see this finally happen.
 	- so many tiny coding style cleanups it's not funny.  Perfect
 	  storm of at least 2 different intern project application
 	  deadlines combined to provide a huge number of new
 	  contributions in this area from people learning how to do
 	  kernel development.  Great job to everyone involved here.
 
 There's also the normal updates for IIO drivers with new IIO drivers and
 updates all over that subsystem.
 
 All of these have been in linux-next for a while with no reported
 issues.

Sami Tolvanen 167d0da23f psci: use function_nocfi for cpu_resume
With CONFIG_CFI_CLANG, the compiler replaces function pointers with
jump table addresses, which results in __pa_symbol returning the
physical address of the jump table entry. As the jump table contains
an immediate jump to an EL1 virtual address, this typically won't
work as intended. Use function_nocfi to get the actual address of
cpu_resume.

Stephen Boyd 257f2935cb firmware: qcom_scm: Workaround lack of "is available" call on SC7180
Some SC7180 firmwares don't implement the QCOM_SCM_INFO_IS_CALL_AVAIL
API, so we can't probe the calling convention. We detect the legacy
calling convention on these firmwares, because the availability call
always fails and legacy is the fallback. This leads to problems where
the rmtfs driver fails to probe, because it tries to assign memory with
a bad calling convention, which then leads to modem failing to load and
all networking, even wifi, to fail. Ouch!

Let's force the calling convention to be what it always is on this SoC,
i.e. arm64. Of course, the calling convention is not the same thing as
implementing the QCOM_SCM_INFO_IS_CALL_AVAIL API. The absence of the "is
this call available" API from the firmware means that any call to
__qcom_scm_is_call_available() fails. This is OK for now though because
none of the calls that are checked for existence are implemented on
firmware running on sc7180. If such a call needs to be checked for
existence in the future, we presume that firmware will implement this
API and then things will "just work".

Stephen Boyd f6ea568f0d firmware: qcom_scm: Reduce locking section for __get_convention()
We shouldn't need to hold this spinlock here around the entire SCM call
into the firmware and back. Instead, we should be able to query the
firmware, potentially in parallel with other CPUs making the same
convention detection firmware call, and then grab the lock to update the
calling convention detected. The convention doesn't change at runtime so
calling into firmware more than once is possibly wasteful but simpler.
Besides, this is the slow path, not the fast path where we've already
detected the convention used.

More importantly, this allows us to add more logic here to workaround
the case where the firmware call to check for availability isn't
implemented in the firmware at all. In that case we can check the
firmware node compatible string and force a calling convention.

Note that we remove the 'has_queried' logic that is repeated twice. That
could lead to the calling convention being printed multiple times to the
kernel logs if the bool is true but __query_convention() is running on
multiple CPUs. We also shorten the time where the lock is held, but we
keep the lock held around the printk because it doesn't seem hugely
important to drop it for that.

Make __qcom_scm_is_call_available() return bool instead of int. The
function has "is" in the name, so it should return a bool to indicate
the truth of the call being available. Unfortunately, it can return a
number < 0 which also looks "true", but not all callers expect that and
thus they think a call is available when really the check to see if the
call is available failed to figure it out.

Evan Green b0077b4b08 firmware: google: Enable s0ix logging by default
Many moons ago, support was added to the SMI handlers to log s0ix entry
and exit. Early iterations of firmware on Apollo Lake correctly returned
"unsupported" for this new command they did not recognize, but
unfortunately also contained a quirk where this command would cause them
to power down rather than resume from s0ix.

Fixes for this quirk were pushed out long ago, so all APL devices still
in the field should have updated firmware. As such, we no longer need to
have the s0ix_logging_enable be opt-in, where every new platform has to
add this to their kernel commandline parameters. Change it to be on by
default.

In theory we could remove the parameter altogether: updated versions of
Chrome OS containing a kernel with this change would also be coupled
with firmware that behaves properly with these commands. Eventually we
should probably do that. For now, convert this to an opt-out parameter
so there's an emergency valve for people who are deliberately running
old firmware, or as an escape hatch in case of unforeseen regressions.

Cristian Marussi d4f9dddd21 firmware: arm_scmi: Add dynamic scmi devices creation
Having added the support for SCMI protocols as modules in order to let
vendors extend the SCMI core with their own additions it seems odd to
then force SCMI drivers built on top to use a static device table to
declare their devices since this way any new SCMI drivers addition
would need the core SCMI device table to be updated too.

Remove the static core device table and let SCMI drivers to simply declare
which device/protocol pair they need at initialization time: the core will
then take care to generate such devices dynamically during platform
initialization or at module loading time, as long as the requested
underlying protocol is defined in the devicetree.

drivers will have been completed.

Cristian Marussi b9f7fd907c firmware: arm_scmi: Convert events registration to protocol handles
Convert all refactored events registration routines to use protocol
handles.

In order to maintain bisectability and to allow protocols and drivers
to be later ported to the new protocol handle interface one by one,
introduce here also some transient code that will be removed later
in order to ease such transition.
