      sparc64: sun4v TLB error power off events · 4ccb9272
      bob picco authored
      
      
      We've witnessed a few TLB events causing the machine to power off because
      of prom_halt. In one case it was some nfs related area during rmmod. Another
      was an mmapper of /dev/mem. A more recent one is an ITLB issue with
      a bad pagesize which could be a hardware bug. Bugs happen but we should
      attempt to not power off the machine and/or hang it when possible.
      
      This is a DTLB error from an mmapper of /dev/mem:
      [root@sparcie ~]# SUN4V-DTLB: Error at TPC[fffff80100903e6c], tl 1
      SUN4V-DTLB: TPC<0xfffff80100903e6c>
      SUN4V-DTLB: O7[fffff801081979d0]
      SUN4V-DTLB: O7<0xfffff801081979d0>
      SUN4V-DTLB: vaddr[fffff80100000000] ctx[1250] pte[98000000000f0610] error[2]
      .
      
      This is recent mainline for ITLB:
      [ 3708.179864] SUN4V-ITLB: TPC<0xfffffc010071cefc>
      [ 3708.188866] SUN4V-ITLB: O7[fffffc010071cee8]
      [ 3708.197377] SUN4V-ITLB: O7<0xfffffc010071cee8>
      [ 3708.206539] SUN4V-ITLB: vaddr[e0003] ctx[1a3c] pte[2900000dcc800eeb] error[4]
      .
      
      Normally sun4v_itlb_error_report() and sun4v_dtlb_error_report() would call
      prom_halt() and drop us to OF command prompt "ok". This isn't the case for
      LDOMs and the machine powers off.
      
      For the HV reported error of HV_ENORADDR for HV HV_MMU_MAP_ADDR_TRAP we cause
      a SIGBUS error by qualifying it within do_sparc64_fault() for fault code mask
      of FAULT_CODE_BAD_RA. This is done when trap level (%tl) is less or equal
      one("1"). Otherwise, for %tl > 1,  we proceed eventually to die_if_kernel().
      
      The logic of this patch was partially inspired by David Miller's feedback.
      
      Power off of large sparc64 machines is painful. Plus die_if_kernel provides
      more context. A reset sequence isn't a brief period on large sparc64 but
      better than power-off/power-on sequence.

      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 related error with allmodconfig:

      "entry.h" needs 'asmlinkage', and "asm/linkage.h" does not provide it.
      So need include "linux/linkage.h" to use generic one instead of.

      ====================
      pull request: wireless 2014-09-05
      
      Please pull this batch of fixes intended for the 3.17 stream...
      
      For the mac80211 bits, Johannes says:
      
      "Here are a few fixes for mac80211. One has been discussed for a while
      and adds a terminating NUL-byte to the alpha2 sent to userspace, which
      shouldn't be necessary but since many places treat it as a string we
      couldn't move to just sending two bytes.
      
      In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
      fix for the recently introduced RX aggregation offload, a revert for
      a broken patch (that luckily didn't really cause any harm) and a small
      fix for alignment in debugfs."
      
      For the iwlwifi bits, Emmanuel says:
      
      "I revert a patch that disabled CTS to self in dvm because users
      reported issues. The revert is CCed to stable since the offending
      patch was sent to stable too. I also bump the firmware API versions
      since a new firmware is coming up. On top of that, Marcel fixes a
      bug I introduced while fixing a bug in our Kconfig file."
      
      Please let me know if there are problems!

      ipv6: restore the behavior of ipv6_sock_ac_drop() · de185ab4
      WANG Cong authored
      It is possible that the interface is already gone after joining
      the list of anycast on this interface as we don't hold a refcount
      for the device, in this case we are safe to ignore the error.
      
      What's more important, for API compatibility we should not
      change this behavior for applications even if it were correct.

      The example code provided with the i2c device interface documentation
      won't compile since it uses the reserved word "register" to name a
      variable.
      
      The compiler fails with this error message:

      Rename the variable "register" to simply "reg" in the example code.

      ufs: fix deadlocks introduced by sb mutex merge · 9ef7db7f
      Alexey Khoroshilov authored
      Commit 0244756e
      
       ("ufs: sb mutex merge + mutex_destroy") introduces
      deadlocks in ufs_new_inode() and ufs_free_inode().
      Most callers of that functions acqure the mutex by themselves and
      ufs_{new,free}_inode() do that via lock_ufs(),
      i.e we have an unavoidable double lock.
      
      The patch proposes to resolve the issue by making sure that
      ufs_{new,free}_inode() are not called with the mutex held.

       "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.

         - a direct IO read/buffered read data corruption
