8480f85e39 Don't complain on .got.plt sections of size zero. Apparently such 
sections are generated by older toolchains (binutils 2.15.90.0.3 ?)

72a3a2f4f2 Make the size calculations inside VG_(mallinfo) 64-bit clean. 
I don't really understand how 'struct mallinfo' makes any sense on a
64-bit platform given that all the field sizes are 32-bit ints, and
surely at least .arena and .uordblocks and probably others could
easily exceed 32-bit range.

178fbd72d3 Tidy up timerfd wrapper stuff a bit: 
* make linux_kernel_2_6_22 return Bool

* linux_kernel_2_6_22: don't assert if /proc/sys/kernel/osrelease
  can't be opened

* PRE(sys_timerfd_create), PRE(sys_signalfd):
  use %ld for Word arguments, and use house types

109d597941 Bug fixes (not in bugzilla): 
- Make sure that Valgrind does not complain when it tries to read the
  debug information of a file of size zero when such a file is mmap()'ed
  into memory.
- Make sure the filename is included in the error message that is
  printed when reading the debug information fails for a file that is mmap()'ed
  into memory.
- Fixed assertion failure that was triggered by supplying an output
  buffer to VG_(seginfo_sect_kind)() that is smaller than the filename
  to be copied into that buffer.

4cae5c3ed5 Merge branches/OTRACK_BY_INSTRUMENTATION into the trunk. This adds 
support to Memcheck for tracking the origin of uninitialised values,
if you use the --track-origins=yes flag.

This currently causes some Memcheck regression tests to fail, because
they now print an extra line of advisory text in their output.  This
will be fixed.

The core-tool interface is slightly changed.  The version number for
the interface needs to be incremented.

18a72f705c Try to handle the situation where an object is first split into a base 
object (without D3 info) and a debuginfo (with D3 info), and then the
base object is prelinked to some nonzero address, but the debuginfo
object is left unchanged.  A nasty and unprincipled hack.

50a23bf861 Don't be quite so paranoid about rejecting symbols that fall outside 
the .text segment.  Instead only reject ones that fall outside the r-x
area.  This is in line with r7427, which instituted such a change in
other places in the system.
