22922deae1 Objtool changes for this cycle were:
- Comprehensive interface overhaul:
    =================================
 
    Objtool's interface has some issues:
 
      - Several features are done unconditionally, without any way to turn
        them off.  Some of them might be surprising.  This makes objtool
        tricky to use, and prevents porting individual features to other
        arches.
 
      - The config dependencies are too coarse-grained.  Objtool enablement is
        tied to CONFIG_STACK_VALIDATION, but it has several other features
        independent of that.
 
      - The objtool subcmds ("check" and "orc") are clumsy: "check" is really
        a subset of "orc", so it has all the same options.  The subcmd model
        has never really worked for objtool, as it only has a single purpose:
        "do some combination of things on an object file".
 
      - The '--lto' and '--vmlinux' options are nonsensical and have
        surprising behavior.
 
    Overhaul the interface:
 
       - get rid of subcmds
 
       - make all features individually selectable
 
       - remove and/or clarify confusing/obsolete options
 
       - update the documentation
 
       - fix some bugs found along the way
 
  - Fix x32 regression
 
  - Fix Kbuild cleanup bugs
 
  - Add scripts/objdump-func helper script to disassemble a single function from an object file.
 
  - Rewrite scripts/faddr2line to be section-aware, by basing it on 'readelf',
    moving it away from 'nm', which doesn't handle multiple sections well,
    which can result in decoding failure.
 
  - Rewrite & fix symbol handling - which had a number of bugs wrt. object files
    that don't have global symbols - which is rare but possible. Also fix a
    bunch of symbol handling bugs found along the way.

143a6252e1 arm64 updates for 5.19:
- Initial support for the ARMv9 Scalable Matrix Extension (SME). SME
   takes the approach used for vectors in SVE and extends this to provide
   architectural support for matrix operations. No KVM support yet, SME
   is disabled in guests.
 
 - Support for crashkernel reservations above ZONE_DMA via the
   'crashkernel=X,high' command line option.
 
 - btrfs search_ioctl() fix for live-lock with sub-page faults.
 
 - arm64 perf updates: support for the Hisilicon "CPA" PMU for monitoring
   coherent I/O traffic, support for Arm's CMN-650 and CMN-700
   interconnect PMUs, minor driver fixes, kerneldoc cleanup.
 
 - Kselftest updates for SME, BTI, MTE.
 
 - Automatic generation of the system register macros from a 'sysreg'
   file describing the register bitfields.
 
 - Update the type of the function argument holding the ESR_ELx register
   value to unsigned long to match the architecture register size
   (originally 32-bit but extended since ARMv8.0).
 
 - stacktrace cleanups.
 
 - ftrace cleanups.
 
 - Miscellaneous updates, most notably: arm64-specific huge_ptep_get(),
   avoid executable mappings in kexec/hibernate code, drop TLB flushing
   from get_clear_flush() (and rename it to get_clear_contig()),
   ARCH_NR_GPIO bumped to 2048 for ARCH_APPLE.

Linus Torvalds
cfe1cb014b A set of patches to prevent crashes in SGX enclaves under heavy memory
pressure:
 
 SGX uses normal RAM allocated from special shmem files as backing storage
 when it runs out of SGX memory (EPC).  The code was overly aggressive when
 freeing shmem pages and was inadvertently freeing perfectly good data.
 This resulted in failures in the SGX instructions used to swap data back
 into SGX memory.
 
 This turned out to be really hard to trigger in mainline.  It was
 originally encountered testing the out-of-tree "SGX2" patches, but later
 reproduced on mainline.
 
 Fix the data loss by being more careful about truncating pages out of
 the backing storage and more judiciously setting pages dirty.

3a755ebcc2 Intel Trust Domain Extensions
This is the Intel version of a confidential computing solution called
 Trust Domain Extensions (TDX). This series adds support to run the
 kernel as part of a TDX guest. It provides similar guest protections to
 AMD's SEV-SNP like guest memory and register state encryption, memory
 integrity protection and a lot more.
 
 Design-wise, it differs from AMD's solution considerably: it uses
 a software module which runs in a special CPU mode called (Secure
 Arbitration Mode) SEAM. As the name suggests, this module serves as sort
 of an arbiter which the confidential guest calls for services it needs
 during its lifetime.
 
 Just like AMD's SNP set, this series reworks and streamlines certain
 parts of x86 arch code so that this feature can be properly accomodated.

eb39e37d5c AMD SEV-SNP support
Add to confidential guests the necessary memory integrity protection
 against malicious hypervisor-based attacks like data replay, memory
 remapping and others, thus achieving a stronger isolation from the
 hypervisor.
 
 At the core of the functionality is a new structure called a reverse
 map table (RMP) with which the guest has a say in which pages get
 assigned to it and gets notified when a page which it owns, gets
 accessed/modified under the covers so that the guest can take an
 appropriate action.
 
 In addition, add support for the whole machinery needed to launch a SNP
 guest, details of which is properly explained in each patch.
 
 And last but not least, the series refactors and improves parts of the
 previous SEV support so that the new code is accomodated properly and
 not just bolted on.

fcfde8a7cf Updates for interrupt core and drivers:
Core code:
 
     - Make the managed interrupts more robust by shutting them down in the
       core code when the assigned affinity mask does not contain online
       CPUs.
 
     - Make the irq simulator chip work on RT
 
     - A small set of cpumask and power manageent cleanups
 
   Drivers:
 
     - A set of changes which mark GPIO interrupt chips immutable to prevent
       the GPIO subsystem from modifying it under the hood. This provides
       the necessary infrastructure and converts a set of GPIO and pinctrl
       drivers over.
 
     - A set of changes to make the pseudo-NMI handling for GICv3 more
       robust: a missing barrier and consistent handling of the priority
       mask.
 
     - Another set of GICv3 improvements and fixes, but nothing outstanding
 
     - The usual set of improvements and cleanups all over the place
 
     - No new irqchip drivers and not even a new device tree binding!

 nocb.2022.04.11b: Callback-offloading updates, mainly simplifications.
 
 rcu-tasks.2022.04.11b: RCU-tasks updates, including some -rt fixups,
 	handling of systems with sparse CPU numbering, and a fix for a
 	boot-time race-condition failure.
 
 srcu.2022.05.03a: Put SRCU on a memory diet in order to reduce the size
 	of the srcu_struct structure.
 
 torture.2022.04.11b: Torture-test updates fixing some bugs in tests and
 	closing some testing holes.

 	most notably ensuring that building rcutorture and friends does
 	not change the RCU-tasks-related Kconfig options.
 
 torturescript.2022.04.20a: Torture-test scripting updates.
