      drm/i915/gvt: ignore unexpected pvinfo write · 971afec3
      Weinan Li authored
      
      There is pvinfo writing come from vgpu might be unexpected, like
      writing to one unknown address, GVT-g should do as reserved register
      to discard any invalid write. Now GVT-g lets it write to the vreg
      without prompt error message, should ignore the unexpected pvinfo
      write access and leave the vreg as the default value.
      
      For possible guest query GVT-g host feature, this returned proper
      value instead of wrong guest setting.
      
      v2: ignore unexpected pvinfo write instead of return predefined value

      Pull x86 fixes from Thomas Gleixner:
       "The accumulated fixes from this and last week:
      
         - Fix vmalloc TLB flush and map range calculations which lead to
           stale TLBs, spurious faults and other hard to diagnose issues.
      
         - Use fault_in_pages_writable() for prefaulting the user stack in the
           FPU code as it's less fragile than the current solution
      
         - Use the PF_KTHREAD flag when checking for a kernel thread instead
           of current->mm as the latter can give the wrong answer due to
           use_mm()
      
         - Compute the vmemmap size correctly for KASLR and 5-Level paging.
           Otherwise this can end up with a way too small vmemmap area.
      
         - Make KASAN and 5-level paging work again by making sure that all
           invalid bits are masked out when computing the P4D offset. This
           worked before but got broken recently when the LDT remap area was
           moved.
      
         - Prevent a NULL pointer dereference in the resource control code
           which can be triggered with certain mount options when the
           requested resource is not available.
      
         - Enforce ordering of microcode loading vs. perf initialization on
           secondary CPUs. Otherwise perf tries to access a non-existing MSR
           as the boot CPU marked it as available.
      
         - Don't stop the resource control group walk early otherwise the
           control bitmaps are not updated correctly and become inconsistent.
      
         - Unbreak kgdb by returning 0 on success from
           kgdb_arch_set_breakpoint() instead of an error code.
      
         - Add more Icelake CPU model defines so depending changes can be
           queued in other trees"

      The MSR in question is MSR_TFA_RTM_FORCE_ABORT and that MSR is emulated
      by microcode. The log above shows that the microcode loader callback
      happens after the PMU restoration, leading to the conjecture that
      because the microcode hasn't been updated yet, that MSR is not present
      yet, leading to the #GP.
      
      Add a microcode loader-specific hotplug vector which comes before
      the PERF vectors and thus executes earlier and makes sure the MSR is
      present.

      Smack: Restore the smackfsdef mount option and add missing prefixes · 6e7739fc
      Casey Schaufler authored
      
      The 5.1 mount system rework changed the smackfsdef mount option to
      smackfsdefault.  This fixes the regression by making smackfsdef treated
      the same way as smackfsdefault.
      
      Also fix the smack_param_specs[] to have "smack" prefixes on all the
      names.  This isn't visible to a user unless they either:
      
       (a) Try to mount a filesystem that's converted to the internal mount API
           and that implements the ->parse_monolithic() context operation - and
           only then if they call security_fs_context_parse_param() rather than
           security_sb_eat_lsm_opts().
      
           There are no examples of this upstream yet, but nfs will probably want
           to do this for nfs2 or nfs3.
      
       (b) Use fsconfig() to configure the filesystem - in which case
           security_fs_context_parse_param() will be called.
      
      This issue is that smack_sb_eat_lsm_opts() checks for the "smack" prefix
      on the options, but smack_fs_context_parse_param() does not.
      
      Fixes: c3300aaf ("smack: get rid of match_token()")
      Fixes: 2febd254 ("smack: Implement filesystem context security hooks")

      The above panic occurs when loading two modules at the same time with

              apply_relocate_add()
      	  *patches read-only code* - BOOM
      
      A similar race exists when toggling ftrace while loading a livepatch
      module.
      
      Fix it by ensuring that the livepatch and ftrace code patching
      operations -- and their respective permissions changes -- are protected
      by the text_mutex.

      tracing: avoid build warning with HAVE_NOP_MCOUNT · cbdaeaf0
      Vasily Gorbik authored
      Selecting HAVE_NOP_MCOUNT enables -mnop-mcount (if gcc supports it)
      and sets CC_USING_NOP_MCOUNT. Reuse __is_defined (which is suitable for
      testing CC_USING_* defines) to avoid conditional compilation and fix
      the following gcc 9 warning on s390:

       "Here are some arm64 fixes for -rc5.
      
        The only non-trivial change (in terms of the diffstat) is fixing our
        SVE ptrace API for big-endian machines, but the majority of this is
        actually the addition of much-needed comments and updates to the
        documentation to try to avoid this mess biting us again in future.
      
        There are still a couple of small things on the horizon, but nothing
        major at this point.
      
        Summary:
      
         - Fix broken SVE ptrace API when running in a big-endian configuration
      
         - Fix performance regression due to off-by-one in TLBI range checking
