       "A set of fixes for x86:
         - Fix the swapped outb() parameters in the KASLR code
         - Fix the PKEY handling at fork which missed to preserve the pkey
           state for the child. Comes with a test case to validate that.
         - Fix the entry stack handling for XEN PV to respect that XEN PV
           systems enter the function already on the current thread stack and
           not on the trampoline.
         - Fix kexec load failure caused by using a stale value when the
           kexec_buf structure is reused for subsequent allocations.
         - Fix a bogus sizeof() in the memory encryption code
         - Enforce PCI dependency for the Intel Low Power Subsystem
         - Enforce PCI_LOCKLESS_CONFIG when PCI is enabled"

       "A fix for namespace label support for non-Intel NVDIMMs that implement
        the ACPI standard label method.
        This has apparently never worked and could wait for v5.1. However it
        has enough visibility with hardware vendors [1] and distro bug
        trackers [2], and low enough risk that I decided it should go in for
        -rc4. The other fixups target the new, for v5.0, nvdimm security
        functionality. The larger init path fixup closes a memory leak and a
        potential userspace lockup due to missed notifications.

          [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1811785
        These have all soaked in -next for a week with no reported issues.
         - Fix support for NVDIMMs that implement the ACPI standard label

           hang condition), and another one-line security cleanup"

      KVM: x86: fix TRACE_INCLUDE_PATH and remove -I. header search paths · 5cd5548f
      Masahiro Yamada authored
      The header search path -I. in kernel Makefiles is very suspicious;
      it allows the compiler to search for headers in the top of $(srctree),
      where obviously no header file exists.
      The reason of having -I. here is to make the incorrectly set
      TRACE_INCLUDE_PATH working.
      As the comment block in include/trace/define_trace.h says,
      TRACE_INCLUDE_PATH should be a relative path to the define_trace.h
      Fix the TRACE_INCLUDE_PATH, and remove the iffy include paths.

      KVM: VMX: Move vmx_vcpu_run()'s VM-Enter asm blob to a helper function · 5ad6ece8
      Sean Christopherson authored
      ...along with the function's STACK_FRAME_NON_STANDARD tag.  Moving the
      asm blob results in a significantly smaller amount of code that is
      marked with STACK_FRAME_NON_STANDARD, which makes it far less likely
      that gcc will split the function and trigger a spurious objtool warning.
      As a bonus, removing STACK_FRAME_NON_STANDARD from vmx_vcpu_run() allows
      the bulk of code to be properly checked by objtool.
      Because %rbp is not loaded via VMCS fields, vmx_vcpu_run() must manually
      save/restore the host's RBP and load the guest's RBP prior to calling
      vmx_vmenter().  Modifying %rbp triggers objtool's stack validation code,
      and so vmx_vcpu_run() is tagged with STACK_FRAME_NON_STANDARD since it's
      impossible to avoid modifying %rbp.
      Unfortunately, vmx_vcpu_run() is also a gigantic function that gcc will
      split into separate functions, e.g. so that pieces of the function can
      be inlined.  Splitting the function means that the compiled Elf file
      will contain one or more vmx_vcpu_run.part.* functions in addition to
      a vmx_vcpu_run function.  Depending on where the function is split,
      objtool may warn about a "call without frame pointer save/setup" in
      vmx_vcpu_run.part.* since objtool's stack validation looks for exact
      names when whitelisting functions tagged with STACK_FRAME_NON_STANDARD.
      Up until recently, the undesirable function splitting was effectively
      blocked because vmx_vcpu_run() was tagged with __noclone.  At the time,
      __noclone had an unintended side effect that put vmx_vcpu_run() into a
      separate optimization unit, which in turn prevented gcc from inlining
      the function (or any of its own function calls) and thus eliminated gcc's
      motivation to split the function.  Removing the __noclone attribute
      allowed gcc to optimize vmx_vcpu_run(), exposing the objtool warning.
      Kudos to Qian Cai for root causing that the fnsplit optimization is what
      caused objtool to complain.

      KVM: nSVM: clear events pending from svm_complete_interrupts() when exiting to L1 · 619ad846
      Vitaly Kuznetsov authored
      kvm-unit-tests' eventinj "NMI failing on IDT" test results in NMI being
      delivered to the host (L1) when it's running nested. The problem seems to
      be: svm_complete_interrupts() raises 'nmi_injected' flag but later we
      decide to reflect EXIT_NPF to L1. The flag remains pending and we do NMI
      injection upon entry so it got delivered to L1 instead of L2.
      It seems that VMX code solves the same issue in prepare_vmcs12(), this was
      introduced with code refactoring in commit 5f3d5799 ("KVM: nVMX: Rework
      event injection and recovery").
