e71365244a When '-d' (one or more) is specified, disallow the client from closing 
fd 2 (stderr) since that's what m_debuglog writes to, and the
resulting disappearance of the debug log can be confusing.

20a55a1469 ML_(generic_PRE_sys_mmap): In the case of a hinted mapping (for the 
client) which aspacemgr accepts at the hint address but the kernel
declines, try again as a non-hinted mapping.  Fixes ld.so mapping
failures observed on ppc32-linux, although the problem potentially
applies to all Linux targets.

bbe7f55813 Merge r6140 (some of): 
- track SysRes changes

- track VG_(am_find_nsegment) const-ness change

- increase number of client syscall args supported from 6 to 8

- simplify type SyscallStatus.  Simply hold a copy of the SysRes
  for the syscall rather than have this be a data structure
  incorporating something very similar to the fields of a SysRes,
  and more besides.  Change various macros in priv_types_n_macros.h
  to match.

- syswrap-main.c: instantiate the various impedance-matching
  functions for AIX.

f92e61becb Merge r6101: 
Syscall wrappers for AIX5.  Unfortunately they duplicate some of the
stuff in syswrap-generic.c since making that compile on AIX is just
too difficult.

ae8215b3ac Create a new module, m_vki, and move all knowledge about the kernel 
interface, except for the syscall numbers, into that.  Mostly this
means moving include/vki-*.h to include/vki/vki-*.h.

include/pub_tool_basics.h previously dragged in the entire kernel
interface.  I've done away with that, so that modules which need to
see the kernel interface now have to include pub_{core,tool}_vki.h
explicitly.  This is why there are many modified .c files -- they have
all acquired an extra #include line.

This certainly breaks all platforms except x86.  Will fix shortly.

070042a4c5 When handling mremap, disallow an expanding in-place remap if it would 
trash some other segment as a result of the expansion.  This fixes
#129866.  I don't know if it is a good solution though.  Causes
none/tests/mremap{,2} to fail now, although I think it is still OK.
mremap really is a semantic disaster area.

0e8a28708c Fix boundary case when trying to use brk() to expand right up to the 
limit of the brk segment.

Because VG_(brk_limit) is the first address beyond the end of the
memory available to the caller of brk() we need to allow it to grow
up to and including the address one page below the end of the space
valgrind has reserved.
