      x86: fix cpu-hotplug regression · 90367556
      Andreas Herrmann authored
      Commit d435d862
      ("cpu hotplug: mce: fix cpu hotplug error handling")
      changed the error handling in mce_cpu_callback.
      
      In cases where not all CPUs are brought up during
      boot (e.g. using maxcpus and additional_cpus parameters)
      mce_cpu_callback now returns NOTFIY_BAD because
      for such CPUs cpu_data is not completely filled when
      the notifier is called. Thus mce_create_device fails right
      at its beginning:
      
              if (!mce_available(&cpu_data[cpu]))
                      return -EIO;
      
      As a quick fix I suggest to check boot_cpu_data for MCE.
      
      To reproduce this regression:
      
      (1) boot with maxcpus=2 addtional_cpus=2 on a 4 CPU x86-64 system
      (2) # echo 1 >/sys/devices/system/cpu/cpu2/online
        -bash: echo: write error: Invalid argument
      
      dmesg shows:
      
      _cpu_up: attempt to bring up CPU 2 failed

      x86: ignore the sys_getcpu() tcache parameter · 4307d1e5
      Ingo Molnar authored
      dont use the vgetcpu tcache - it's causing problems with tasks
      migrating, they'll see the old cache up to a jiffy after the
      migration, further increasing the costs of the migration.
      
      In the worst case they see a complete bogus information from
      the tcache, when a sys_getcpu() call "invalidated" the cache
      info by incrementing the jiffies _and_ the cpuid info in the
      cache and the following vdso_getcpu() call happens after
      vdso_jiffies have been incremented.

      SELinux: return EOPNOTSUPP not ENOTSUPP · ec418781
      Eric Paris authored
      ENOTSUPP is not a valid error code in the kernel (it is defined in some
      NFS internal error codes and has been improperly used other places).  In
      the !CONFIG_SECURITY_SELINUX case though it is possible that we could
      return this from selinux_audit_rule_init().  This patch just returns the
      userspace valid EOPNOTSUPP.

      dirty page balancing: Get rid of broken unmapped_ratio logic · 8c086340
      Linus Torvalds authored
      This code harks back to the days when we didn't count dirty mapped
      pages, which led us to try to balance the number of dirty unmapped pages
      by how much unmapped memory there was in the system.
      
      That makes no sense any more, since now the dirty counts include the
      mapped pages.  Not to mention that the math doesn't work with HIGHMEM
      machines anyway, and causes the unmapped_ratio to potentially turn
      negative (which we do catch thanks to clamping it at a minimum value,
      but I mention that as an indication of how broken the code is).
      
      The code also was written at a time when the default dirty ratio was
      much larger, and the unmapped_ratio logic effectively capped that large
      dirty ratio a bit.  Again, we've since lowered the dirty ratio rather
      aggressively, further lessening the point of that code.
