ff6135959a A much quieter cycle for documentation (happily), with, one hopes, the bulk
of the churn behind us.  Significant stuff in this pull includes:
 
  - A set of new Chinese translations
  - Italian translation updates
  - A mechanism from Mauro to automatically format Documentation/features
    for the built docs
  - Automatic cross references without explicit :ref: markup
  - A new reset-controller document
  - An extensive new document on reporting problems from Thorsten
 
 That last patch also adds the CC-BY-4.0 license to LICENSES/dual; there was
 some discussion on this, but we seem to have consensus and an ack from Greg
 for that addition.

9c70f04678 The main part of this branch is the ongoing fight against windmills in
an attempt to have userspace tools not poke at naked MSRs. This round
 deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct poking into it
 by our in-tree tools in favor of the proper "energy_perf_bias" sysfs
 interface which we already have.
 
 In addition, the msr.ko write filtering's error message points to a new
 summary page which contains the info we collected from helpful reporters
 about which userspace tools write MSRs:
 
   https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about
 
 along with the current status of their conversion.
 
 Rest is the usual small fixes and improvements.

5583ff677b "Intel SGX is new hardware functionality that can be used by
applications to populate protected regions of user code and data called
 enclaves. Once activated, the new hardware protects enclave code and
 data from outside access and modification.
 
 Enclaves provide a place to store secrets and process data with those
 secrets. SGX has been used, for example, to decrypt video without
 exposing the decryption keys to nosy debuggers that might be used to
 subvert DRM. Software has generally been rewritten specifically to
 run in enclaves, but there are also projects that try to run limited
 unmodified software in enclaves."
 
 Most of the functionality is concentrated into arch/x86/kernel/cpu/sgx/
 except the addition of a new mprotect() hook to control enclave page
 permissions and support for vDSO exceptions fixup which will is used by
 SGX enclaves.

Add support for the AES/SM4 crypto engine included in the Offload and
Crypto Subsystem (OCS) of the Intel Keem Bay SoC, thus enabling
hardware-acceleration for the following transformations:

- ecb(aes), cbc(aes), ctr(aes), cts(cbc(aes)), gcm(aes) and cbc(aes);
  supported for 128-bit and 256-bit keys.

- ecb(sm4), cbc(sm4), ctr(sm4), cts(cbc(sm4)), gcm(sm4) and cbc(sm4);
  supported for 128-bit keys.

The driver passes crypto manager self-tests, including the extra tests
(CRYPTO_MANAGER_EXTRA_TESTS=y).

db2082700a MAINTAINERS: add a limited ARM and ARM64 SoC entry
It is expected for ARM and ARM64 SoC related code to go through
sub-architecture maintainers.  Their addresses were therefore not
documented to push patch traffic through sub-architecture maintainers.

However when patches touch generic code, e.g. multi_v7_defconfig, the
patch might not be picked up by them and instead should go to the SoC
maintainers - Arnd and Olof.

Add a minimal maintainer's entry for SoC covering only Makefile, so it
will not appear on most of submissions (except new devicetree boards).
It will though serve as a documentation and reference for cases when
submitter does not know where to send his SoC-related patches.

     infrastructure work on PowerPC/Pseries. PowerPC does not use the
     generic infrastructure for setting up PCI/MSI interrupts and the
     multiqueue changes failed to update the legacy PCI/MSI infrastructure.
