      Revert "x86/mm/legacy: Populate the user page-table with user pgd's" · 61a6bd83
      Joerg Roedel 提交于
      This reverts commit 1f40a46c.
      
      It turned out that this patch is not sufficient to enable PTI on 32 bit
      systems with legacy 2-level page-tables. In this paging mode the huge-page
      PTEs are in the top-level page-table directory, where also the mirroring to
      the user-space page-table happens. So every huge PTE exits twice, in the
      kernel and in the user page-table.
      
      That means that accessed/dirty bits need to be fetched from two PTEs in
      this mode to be safe, but this is not trivial to implement because it needs
      changes to generic code just for the sake of enabling PTI with 32-bit
      legacy paging. As all systems that need PTI should support PAE anyway,
      remove support for PTI when 32-bit legacy paging is used.

      xen/gntdev: fix up blockable calls to mn_invl_range_start · 58a57569
      Michal Hocko 提交于
      Patch series "mmu_notifiers follow ups".
      
      Tetsuo has noticed some fallouts from 93065ac7 ("mm, oom: distinguish
      blockable mode for mmu notifiers").  One of them has been fixed and picked
      up by AMD/DRM maintainer [1].  XEN issue is fixed by patch 1.  I have also
      clarified expectations about blockable semantic of invalidate_range_end.
      Finally the last patch removes MMU_INVALIDATE_DOES_NOT_BLOCK which is no
      longer used nor needed.
      
      [1] http://lkml.kernel.org/r/20180824135257.GU29735@dhcp22.suse.cz
      
      This patch (of 3):
      
      93065ac7 ("mm, oom: distinguish blockable mode for mmu notifiers") has
      introduced blockable parameter to all mmu_notifiers and the notifier has
      to back off when called in !blockable case and it could block down the
      road.
      
      The above commit implemented that for mn_invl_range_start but both
      in_range checks are done unconditionally regardless of the blockable mode
      and as such they would fail all the time for regular calls.  Fix this by
      checking blockable parameter as well.
      
      Once we are there we can remove the stale TODO.  The lock has to be
      sleepable because we wait for completion down in gnttab_unmap_refs_sync.

      xen/balloon: add runtime control for scrubbing ballooned out pages · 197ecb38
      Marek Marczykowski-Górecki 提交于
      Scrubbing pages on initial balloon down can take some time, especially
      in nested virtualization case (nested EPT is slow). When HVM/PVH guest is
      started with memory= significantly lower than maxmem=, all the extra
      pages will be scrubbed before returning to Xen. But since most of them
      weren't used at all at that point, Xen needs to populate them first
      (from populate-on-demand pool). In nested virt case (Xen inside KVM)
      this slows down the guest boot by 15-30s with just 1.5GB needed to be
      returned to Xen.
      
      Add runtime parameter to enable/disable it, to allow initially disabling
      scrubbing, then enable it back during boot (for example in initramfs).
      Such usage relies on assumption that a) most pages ballooned out during
      initial boot weren't used at all, and b) even if they were, very few
      secrets are in the guest at that time (before any serious userspace
      kicks in).
      Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also
      enabled by default), controlling default value for the new runtime
      switch.

      asm-generic: io: Fix ioport_map() for !CONFIG_GENERIC_IOMAP && CONFIG_INDIRECT_PIO · 500dd232
      Andrew Murray 提交于
      The !CONFIG_GENERIC_IOMAP version of ioport_map uses MMIO_UPPER_LIMIT to
      prevent users from making I/O accesses outside the expected I/O range -
      however it erroneously treats MMIO_UPPER_LIMIT as a mask which is
      contradictory to its other users.
      
      The introduction of CONFIG_INDIRECT_PIO, which subtracts an arbitrary
      amount from IO_SPACE_LIMIT to form MMIO_UPPER_LIMIT, results in ioport_map
      mangling the given port rather than capping it.
      
      We address this by aligning more closely with the CONFIG_GENERIC_IOMAP
      implementation of ioport_map by using the comparison operator and
      returning NULL where the port exceeds MMIO_UPPER_LIMIT. Though note that
      we preserve the existing behavior of masking with IO_SPACE_LIMIT such that
      we don't break existing buggy drivers that somehow rely on this masking.

       - Fix for DM thin-provisioning to avoid data corruption that was a
         side-effect of needing to abort DM thin metadata transaction due to
         running out of metadata space. Fix is to reserve a small amount of
         metadata space so that once it is used the DM thin-pool can finish
         its active transaction before switching to read-only mode.
