       "Device tree contents continue to be the largest branches we submit.

         - Freescale i.MX 7Solo
         - Broadcom BCM23550

        Some of the other delta that is sticking out, line-count wise:
         - Exynos moves of IP blocks under an SoC bus, which causes a large
           delta due to indentation changes
         - a new Tegra K1 board: Apalis

      MIPS: KVM: Reset CP0_PageMask during host TLB flush · a700434d
      James Hogan authored
      KVM sometimes flushes host TLB entries, reading each one to check if it
      corresponds to a guest KSeg0 address. In the absence of EntryHi.EHInv
      bits to invalidate the whole entry, the entries will be set to unique
      virtual addresses in KSeg0 (which is not TLB mapped), spaced 2*PAGE_SIZE
      apart.
      
      The TLB read however will clobber the CP0_PageMask register with
      whatever page size that TLB entry had, and that same page size will be
      written back into the TLB entry along with the unique address.
      
      This would cause breakage when transparent huge pages are enabled on
      64-bit host kernels, since huge page entries will overlap other nearby
      entries when separated by only 2*PAGE_SIZE, causing a machine check
      exception.
      
      Fix this by restoring the old CP0_PageMask value (which should be set to
      the normal page size) after reading the TLB entry if we're going to go
      ahead and invalidate it.

      James Hogan authored
      When emulating MFC0 instructions to load 32-bit values from guest COP0
      registers and the RDHWR instruction to read the CC (Count) register,
      sign extend the result to comply with the MIPS64 architecture. The

      Prior to MIPS64r6 it was UNDEFINED to perform a 64-bit read or write of
      a 32-bit COP0 register. Since this is dynamically generated code,
      generate the right type of access depending on whether the kernel is

      MIPS: KVM: Make entry code MIPS64 friendly · e41637d8
      James Hogan authored
      The MIPS KVM entry code (originally kvm_locore.S, later locore.S, and
      now entry.c) has never quite been right when built for 64-bit, using
      32-bit instructions when 64-bit instructions were needed for handling
      64-bit registers and pointers. Fix several cases of this now.
      
      The changes roughly fall into the following categories.
      
      - COP0 scratch registers contain guest register values and the VCPU
        pointer, and are themselves full width. Similarly CP0_EPC and
        CP0_BadVAddr registers are full width (even though technically we
        don't support 64-bit guest address spaces with trap & emulate KVM).
        Use MFC0/MTC0 for accessing them.
      
      - Handling of stack pointers and the VCPU pointer must match the pointer
        size of the kernel ABI (always o32 or n64), so use ADDIU.
      
      - The CPU number in thread_info, and the guest_{user,kernel}_asid arrays
        in kvm_vcpu_arch are all 32 bit integers, so use lw (instead of LW) to
        load them.

      MIPS: KVM: Use kmap instead of CKSEG0ADDR() · 28cc5bd5
      James Hogan authored
      There are several unportable uses of CKSEG0ADDR() in MIPS KVM, which
      implicitly assume that a host physical address will be in the low 512MB
      of the physical address space (accessible in KSeg0). These assumptions
      don't hold for highmem or on 64-bit kernels.
      
      When interpreting the guest physical address when reading or overwriting
      a trapping instruction, use kmap_atomic() to get a usable virtual
      address to access guest memory, which is portable to 64-bit and highmem
      kernels.

      James Hogan authored
      Calculate the PFN of the commpage using virt_to_phys() instead of
      CPHYSADDR(). This is more portable as kzalloc() may allocate from XKPhys
      instead of KSeg0 on 64-bit kernels, which CPHYSADDR() doesn't handle.
      This is sufficient for highmem kernels too since kzalloc() will allocate
      from lowmem in KSeg0.

      MIPS: Fix definition of KSEGX() for 64-bit · 6002bdd3
      James Hogan authored
      The KSEGX() macro is defined to 32-bit sign extend the address argument
      and logically AND the result with 0xe0000000, with the final result
      usually compared against one of the CKSEG macros. However the literal
      0xe0000000 is unsigned as the high bit is set, and is therefore
      zero-extended on 64-bit kernels, resulting in the sign extension bits of
      the argument being masked to zero. This results in the odd situation
      where:
      
        KSEGX(CKSEG) != CKSEG
        (0xffffffff80000000 & 0x00000000e0000000) != 0xffffffff80000000)
      
      Fix this by 32-bit sign extending the 0xe0000000 literal using
      _ACAST32_.
      
      This will help some MIPS KVM code handling 32-bit guest addresses to
      work on 64-bit host kernels, but will also affect KSEGX in
      dec_kn01_be_backend() on a 64-bit DECstation kernel, and the SiByte DMA
      page ops KSEGX check in clear_page() and copy_page() on 64-bit SB1
      kernels, neither of which appear to be designed with 64-bit segments in
      mind anyway.

      KVM: VMX: Add VMCS to CPU's loaded VMCSs before VMPTRLD · b80c76ec
      Jim Mattson authored
      Kexec needs to know the addresses of all VMCSs that are active on
      each CPU, so that it can flush them from the VMCS caches. It is
      safe to record superfluous addresses that are not associated with
      an active VMCS, but it is not safe to omit an address associated
      with an active VMCS.
      
      After a call to vmcs_load, the VMCS that was loaded is active on
      the CPU. The VMCS should be added to the CPU's list of active
      VMCSs before it is loaded.

      kvm: x86: nVMX: maintain internal copy of current VMCS · 4f2777bc
      David Matlack authored
      KVM maintains L1's current VMCS in guest memory, at the guest physical
      page identified by the argument to VMPTRLD. This makes hairy
      time-of-check to time-of-use bugs possible,as VCPUs can be writing
      the the VMCS page in memory while KVM is emulating VMLAUNCH and
      VMRESUME.
      
      The spec documents that writing to the VMCS page while it is loaded is
      "undefined". Therefore it is reasonable to load the entire VMCS into
      an internal cache during VMPTRLD and ignore writes to the VMCS page
      -- the guest should be using VMREAD and VMWRITE to access the current
      VMCS.
      
      To adhere to the spec, KVM should flush the current VMCS during VMPTRLD,
      and the target VMCS during VMCLEAR (as given by the operand to VMCLEAR).
      Since this implementation of VMCS caching only maintains the the current
      VMCS, VMCLEAR will only do a flush if the operand to VMCLEAR is the
      current VMCS pointer.
      
      KVM will also flush during VMXOFF, which is not mandated by the spec,
      but also not in conflict with the spec.
