      arch/microblaze/include/asm/uaccess.h: Use pr_devel() instead of pr_debug() · de295cf0
      Chen Gang authored
      
      
      When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which
      also depends on the modules number in Makefile. The related information
      in "scripts/Makefile.lib" line 94:
      
        # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will
        # end up in (or would, if it gets compiled in)
        # Note: Files that end up in two or more modules are compiled without the
        #       KBUILD_MODNAME definition. The reason is that any made-up name would
        #       differ in different configs.
      
      For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in
      one line, so cause compiling issue. And 'uaccess.h' is a common shared
      header (not specially for drivers), so use pr_devel() instead of is OK.

       "The fixes all address recently discovered data corruption issues.
      
        The original Direct IO issue was discovered by Chris Mason @ Facebook
        on a production workload which mixed buffered reads with direct reads
        and writes IO to the same file.  The fix for that exposed other issues
        with page invalidation (exposed by millions of fsx operations) failing
        due to dirty buffers beyond EOF.
      
        Finally, the collapse_range code could also cause problems due to
        racing writeback changing the extent map while it was being shifted
        around.  The commits for that problem are simple mitigation fixes that
        prevent the problem from occuring.  A more robust fix for 3.18 that
        addresses the underlying problem is currently being worked on by
        Brian.
      
        Summary of fixes:
         - a direct IO read/buffered read data corruption
         - the associated fallout from the DIO data corruption fix
         - collapse range bugs that are potential data corruption issues"

      timekeeping: Update timekeeper before updating vsyscall and pvclock · 9bf2419f
      Thomas Gleixner authored
      The update_walltime() code works on the shadow timekeeper to make the
      seqcount protected region as short as possible. But that update to the
      shadow timekeeper does not update all timekeeper fields because it's
      sufficient to do that once before it becomes life. One of these fields
      is tkr.base_mono. That stays stale in the shadow timekeeper unless an
      operation happens which copies the real timekeeper to the shadow.
      
      The update function is called after the update calls to vsyscall and
      pvclock. While not correct, it did not cause any problems because none
      of the invoked update functions used base_mono.
      
      commit cbcf2dd3
      
       (x86: kvm: Make kvm_get_time_and_clockread()
      nanoseconds based) changed that in the kvm pvclock update function, so
      the stale mono_base value got used and caused kvm-clock to malfunction.
      
      Put the update where it belongs and fix the issue.
