      random: allow architectures to optionally define random_get_entropy() · 61875f30
      Theodore Ts'o authored
      Allow architectures which have a disabled get_cycles() function to
      provide a random_get_entropy() function which provides a fine-grained,
      rapidly changing counter that can be used by the /dev/random driver.
      
      For example, an architecture might have a rapidly changing register
      used to control random TLB cache eviction, or DRAM refresh that
      doesn't meet the requirements of get_cycles(), but which is good
      enough for the needs of the random driver.

      kvm: ppc: booke: check range page invalidation progress on page setup · 40fde70d
      Bharat Bhushan authored
      When the MM code is invalidating a range of pages, it calls the KVM
      kvm_mmu_notifier_invalidate_range_start() notifier function, which calls
      kvm_unmap_hva_range(), which arranges to flush all the TLBs for guest pages.
      However, the Linux PTEs for the range being flushed are still valid at
      that point.  We are not supposed to establish any new references to pages
      in the range until the ...range_end() notifier gets called.
      The PPC-specific KVM code doesn't get any explicit notification of that;
      instead, we are supposed to use mmu_notifier_retry() to test whether we
      are or have been inside a range flush notifier pair while we have been
      referencing a page.
      
      This patch calls the mmu_notifier_retry() while mapping the guest
      page to ensure we are not referencing a page when in range invalidation.
      
      This call is inside a region locked with kvm->mmu_lock, which is the
      same lock that is called by the KVM MMU notifier functions, thus
      ensuring that no new notification can proceed while we are in the
      locked region.

      KVM: PPC: Book3S HV: Fix typo in saving DSCR · cfc86025
      Paul Mackerras authored
      This fixes a typo in the code that saves the guest DSCR (Data Stream
      Control Register) into the kvm_vcpu_arch struct on guest exit.  The
      effect of the typo was that the DSCR value was saved in the wrong place,
      so changes to the DSCR by the guest didn't persist across guest exit
      and entry, and some host kernel memory got corrupted.

      KVM: nVMX: fix shadow on EPT · d0d538b9
      Gleb Natapov authored
      72f85795 broke shadow on EPT. This patch reverts it and fixes PAE
      on nEPT (which reverted commit fixed) in other way.
      
      Shadow on EPT is now broken because while L1 builds shadow page table
      for L2 (which is PAE while L2 is in real mode) it never loads L2's
      GUEST_PDPTR[0-3].  They do not need to be loaded because without nested
      virtualization HW does this during guest entry if EPT is disabled,
      but in our case L0 emulates L2's vmentry while EPT is enables, so we
      cannot rely on vmcs12->guest_pdptr[0-3] to contain up-to-date values
      and need to re-read PDPTEs from L2 memory. This is what kvm_set_cr3()
      is doing, but by clearing cache bits during L2 vmentry we drop values
      that kvm_set_cr3() read from memory.
      
      So why the same code does not work for PAE on nEPT? kvm_set_cr3()
      reads pdptes into vcpu->arch.walk_mmu->pdptrs[]. walk_mmu points to
      vcpu->arch.nested_mmu while nested guest is running, but ept_load_pdptrs()
      uses vcpu->arch.mmu which contain incorrect values. Fix that by using
      walk_mmu in ept_(load|save)_pdptrs.

      Merge branch 'for-linus' of git://git.samba.org/sfrench/cifs-2.6 · a5c984cc
      Linus Torvalds authored
      Pull CIFS fixes from Steve French:
       "Small set of cifs fixes.  Most important is Jeff's fix that works
        around disconnection problems which can be caused by simultaneous use
        of user space tools (starting a long running smbclient backup then
        doing a cifs kernel mount) or multiple cifs mounts through a NAT, and
        Jim's fix to deal with reexport of cifs share.
      
        I expect to send two more cifs fixes next week (being tested now) -
        fixes to address an SMB2 unmount hang when server dies and a fix for
        cifs symlink handling of Windows "NFS" symlinks"
      
      * 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
        [CIFS] update cifs.ko version
        [CIFS] Remove ext2 flags that have been moved to fs.h
        [CIFS] Provide sane values for nlink
        cifs: stop trying to use virtual circuits
        CIFS: FS-Cache: Uncache unread pages in cifs_readpages() before freeing them

      Linus Torvalds authored
      Pull PCI fix from Bjorn Helgaas:
       "We merged what was intended to be an MMCONFIG cleanup, but in fact,
        for systems without _CBA (which is almost everything), it broke
        extended config space for domain 0 and it broke all config space for
        other domains.
      
        This reverts the change"
