      PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected · b2b49ccb
      Rafael J. Wysocki authored
      The number of and dependencies between high-level power management
      Kconfig options make life much harder than necessary.  Several
      conbinations of them have to be tested and supported, even though
      some of those combinations are very rarely used in practice (if
      they are used in practice at all).  Moreover, the fact that we
      have separate independent Kconfig options for runtime PM and
      system suspend is a serious obstacle for integration between
      the two frameworks.
      To overcome these difficulties, always select PM_RUNTIME if PM_SLEEP
      is set.  Among other things, this will allow system suspend callbacks
      provided by bus types and device drivers to rely on the runtime PM
      framework regardless of the kernel configuration.

      Pull MTD fixes from Brian Norris:
       "Three main MTD fixes for 3.18:
         - A regression from 3.16 which was noticed in 3.17.  With the
           restructuring of the m25p80.c driver and the SPI NOR library
           framework, we omitted proper listing of the SPI device IDs.  This
           means m25p80.c wouldn't auto-load (modprobe) properly when built as
           a module.  For now, we duplicate the device IDs into both modules.
         - The OMAP / ELM modules were depending on an implicit link ordering.
           Use deferred probing so that the new link order (in 3.18-rc) can
           still allow for successful probing.
         - Fix suspend/resume support for LH28F640BF NOR flash"

      irda: stop calling sk_prot->disconnect() on connection failure · 4cb8c359
      Linus Torvalds authored
      The sk_prot is irda's own set of protocol handlers, so irda should
      statically know what that function is anyway, without using an indirect
      pointer.  And as it happens, we know *exactly* what that pointer is
      statically: it's NULL, because irda doesn't define a disconnect
      So calling that function is doubly wrong, and will just cause an oops.

      KVM: nVMX: Disable preemption while reading from shadow VMCS · 282da870
      Jan Kiszka authored
      In order to access the shadow VMCS, we need to load it. At this point,
      vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
      we now get preempted by Linux, vmx_vcpu_put and, on return, the
      vmx_vcpu_load will work against the wrong vmcs. That can cause
      copy_shadow_to_vmcs12 to corrupt the vmcs12 state.
      Fix the issue by disabling preemption during the copy operation.
      copy_vmcs12_to_shadow is safe from this issue as it is executed by
      vmx_vcpu_run when preemption is already disabled before vmentry.
      This bug is exposed by running Jailhouse within KVM on CPUs with
      shadow VMCS support.  Jailhouse never expects an interrupt pending
      vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
      is preempted, the active VMCS happens to have the virtual interrupt
      pending flag set in the CPU-based execution controls.

      segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may

      Pull ACPI and power management fixes from Rafael Wysocki:
       "These are fixes received after my previous pull request plus one that
        has been in the works for quite a while, but its previous version
        caused problems to happen, so it's been deferred till now.
        Fixed are two recent regressions (MFD enumeration and cpufreq-dt),
        ACPI EC regression introduced in 3.17, system suspend error code path
        regression introduced in 3.15, an older bug related to recovery from
        failing resume from hibernation and a cpufreq-dt driver issue related
        to operation performance points.
         - Fix a crash on r8a7791/koelsch during resume from system suspend
           caused by a recent cpufreq-dt commit (Geert Uytterhoeven).
         - Fix an MFD enumeration problem introduced by a recent commit adding
           ACPI support to the MFD subsystem that exposed a weakness in the
           ACPI core causing ACPI enumeration to be applied to all devices
           associated with one ACPI companion object, although it should be
           used for one of them only (Mika Westerberg).
         - Fix an ACPI EC regression introduced during the 3.17 cycle causing
           some Samsung laptops to misbehave as a result of a workaround
           targeted at some Acer machines.  That includes a revert of a commit
           that went too far and a quirk for the Acer machines in question.
           From Lv Zheng.
         - Fix a regression in the system suspend error code path introduced
           during the 3.15 cycle that causes it to fail to take errors from
           asychronous execution of "late" suspend callbacks into account
           (Imre Deak).
         - Fix a long-standing bug in the hibernation resume error code path
           that fails to roll back everything correcty on "freeze" callback
           errors and leaves some devices in a "suspended" state causing more
           breakage to happen subsequently (Imre Deak).
         - Make the cpufreq-dt driver disable operation performance points
           that are not supported by the VR connected to the CPU voltage plane
           with acceptable tolerance instead of constantly failing voltage
           scaling later on (Lucas Stach)"

      x86_64, entry: Fix out of bounds read on sysenter · 653bc77a
      Andy Lutomirski authored
      Rusty noticed a Really Bad Bug (tm) in my NT fix.  The entry code
      reads out of bounds, causing the NT fix to be unreliable.  But, and
      this is much, much worse, if your stack is somehow just below the
      top of the direct map (or a hole), you read out of bounds and crash.
      Excerpt from the crash:
      [    1.129513] RSP: 0018:ffff88001da4bf88  EFLAGS: 00010296
        2b:*    f7 84 24 90 00 00 00     testl  $0x4000,0x90(%rsp)
      That read is deterministically above the top of the stack.  I
      thought I even single-stepped through this code when I wrote it to
      check the offset, but I clearly screwed it up.
      Fixes: 8c7aa698

            NULL.  Fix from Florian Westphal.
            This is crummy, and longer term will be fixed to just return error
            pointers or a real SKB.
