      perf tools: Bool functions shouldn't return -1 · bf644563
      Peter Senna Tschudin authored
      Returning a negative value for a boolean function seem to have the
      undesired effect of returning true. Replace -1 by false in a
      bool-returning function.
      
      The diff of the .s file before and after the change (for x86_64):
      
        3907c3907
        < 	movl	$1, %ebx
        ---
        > 	xorl	%ebx, %ebx
      
      while if -1 is replaced by true, the diff is empty.
      
      This issue was found by the following Coccinelle semantic patch:
      
        <smpl>

        identifier f;
        constant C;

      wraps ceph_ts into a kvec and adds it to con->out_kvec array, yet
      ceph_ts becomes invalid on return from prepare_write_keepalive().  As
      a result, we send out bogus keepalive2 stamps.  Fix this by encoding
      into a ceph_timespec member, similar to how acks are read and written.

        [acme@rhel5 linux]$
      
      And this block will not be compiled:
      
        #ifndef HAVE_ELF_GETPHDRNUM_SUPPORT
        static int elf_getphdrnum(Elf *elf, size_t *dst)
        ...
        #endif
      
      So, if elf_getphdrnum() is being defined somewhere, there is a problem
      with the test that is not detecting that function, go fix it.

      arm64: errata: add module build workaround for erratum #843419 · df057cc7
      Will Deacon authored
      Cortex-A53 processors <= r0p4 are affected by erratum #843419 which can
      lead to a memory access using an incorrect address in certain sequences
      headed by an ADRP instruction.
      
      There is a linker fix to generate veneers for ADRP instructions, but
      this doesn't work for kernel modules which are built as unlinked ELF
      objects.
      
      This patch adds a new config option for the erratum which, when enabled,
      builds kernel modules with the mcmodel=large flag. This uses absolute
      addressing for all kernel symbols, thereby removing the use of ADRP as
      a PC-relative form of addressing. The ADRP relocs are removed from the
      module loader so that we fail to load any potentially affected modules.

      arm64: compat: fix vfp save/restore across signal handlers in big-endian · bdec97a8
      Will Deacon authored
      When saving/restoring the VFP registers from a compat (AArch32)
      signal frame, we rely on the compat registers forming a prefix of the
      native register file and therefore make use of copy_{to,from}_user to
      transfer between the native fpsimd_state and the compat_vfp_sigframe.
      
      Unfortunately, this doesn't work so well in a big-endian environment.
      Our fpsimd save/restore code operates directly on 128-bit quantities
      (Q registers) whereas the compat_vfp_sigframe represents the registers
      as an array of 64-bit (D) registers. The architecture packs the compat D
      registers into the Q registers, with the least significant bytes holding
      the lower register. Consequently, we need to swap the 64-bit halves when
      converting between these two representations on a big-endian machine.
      
      This patch replaces the __copy_{to,from}_user invocations in our
      compat VFP signal handling code with explicit __put_user loops that
      operate on 64-bit values and swap them accordingly.

      perf stat: Fix per-pkg event reporting bug · 02d8dabc
      Stephane Eranian authored
      Per-pkg events need to be captured once per processor socket. The code
      in check_per_pkg() ensures only one value per processor package is used.
      However there is a problem with this function in case the first CPU of
      the package does not measure anything for the per-pkg event, but other
      CPUs do.
      
      Consider the following:
      
        $ create cgroup FOO; echo $$ >FOO/tasks; taskset -c 1 noploop &
        $ perf stat -a -I 1000 -e intel_cqm/llc_occupancy/ -G FOO sleep 100
          1.00000 <not counted> Bytes intel_cqm/llc_occupancy/  FOO
      
      The reason for this is that CPU0 in the cgroup has nothing running on it.
      Yet check_per_plg() will mark socket0 as processed and no other event
      value will be considered for the socket.
      
      This patch fixes the problem by having check_per_pkg() only consider
      events which actually ran.

      Pull rdma driver move from Doug Ledford:
       "This is a move only, no functional changes.
      
        I tried to get it in prior to the rc1 release, but we were waiting on
        IBM to get back to us that they were OK with the deprecation and
        eventual removal of this driver.  That OK didn't materialize until
        last week, so integration and testing time pushed us beyond the rc1
        release.
      
        Summary:
      
         - Move ehca driver to staging/rdma and schedule for deletion"

           compiler to catch these but error pointers by nailing them as an
           err pointer intrinsic type or something seem to be a "no can do".
           In any case, cocinelle is obviously up to the task, better than
           bugs staying around.
      
         - Better error handling for NULL GPIO chips.

         - Return value checks and thus nicer errorpath for two drivers.

         - Propagate errors from GPIO chip ->get() vtable call.  It turned out
           these can actually fail sometimes, especially on slowpath
           controllers doing I2C traffic and similar.
      
         - Update documentation to be in sync with the massive changes in the
           v4.3 merge window, phew.
