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.

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.

418aae5c97 Hmm. Perhaps all those top-level pieces of assembly weren't such a
clever idea.  There's no reason to assume the assembler is in
.text-mode when it encounters them, and as gcc 2.96 rudely
demonstrates, sometimes it isn't.  So put .text in front of all of
them.

287d92271f The m_syswrap subsystem is Valgrind's model of how the kernel behaves
with respect to syscalls.  It is detailed and comprehensive but does
not offer a way to deal with minor deviations in behaviour from the
vanilla kernel sources, either due to running a hacked kernel or
running a vanilla kernel with a custom kernel module loaded.

This commit adds a flexible way to handle such cases without polluting
the vanilla handler syswrap-*.c files or their supporting vki_*.h
header files.  For each OS, a syswrap-OS-variants.c file is added,
containing wrappers for variants of OS.  A new command line flag
--kernel-variants= carries a comma separated list of variant names
that apply to the current run.  There are no other changes.

6c610b89c7 Rationalise the mmap system call handling - after examining the kernel
source it turns out that there are five different versions of mmap for
the three platforms we currently support:

  - On x86-linux there is mmap (aka old_mmap) which takes the
    arguments in a memory block and the offset in bytes; and
    mmap2 (aka sys_mmap2) which takes the arguments in the normal
    way and the offset in pages.

  - On ppc32-linux there is mmap (aka sys_mmap) which takes the
    arguments in the normal way and the offset in bytes; and
    mmap2 (aka sys_mmap2) which takes the arguments in the normal
    way and the offset in pages.

  - On amd64-linux everything is simple and there is just the one
    call, mmap (aka sys_mmap)  which takes the arguments in the normal
    way and the offset in bytes.

To reconcile all this I have created a generic handler and then
written five platform specific wrappers which normalise all the
arguments and then call the generic handler.

I have also modified the address space manager to use mmap2 rather
than mmap on x86 and ppc32 so that large offsets can be correctly
handled.

There is still an issue of OffT truncating offsets as we go through
the address space manager that will need to be addressed.

98e527a62c A corresponding fix to 4823: don't deal with MAP_FIXED case directly
here; instead uniformly pass all requests to VG_(am_get_advisory), so
that layout policy is controlled from one place only.

b98ac01c9f Get rid of pub_core_main.h, so that m_main is not imported by anyone,
and so is not part of a module cycle.  This requires a moderately
grotty hack of passing a continuation-function pointer in a global
variable.

cc8ccbbfb4 This commit merges in changes from branches/ASPACEM (specifically,
changes from r4341 through r4787 inclusive).  That branch is now dead.
Please do not commit anything else to it.

For the most part the merge was not troublesome.  The main areas of
uncertainty are:

- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
  and include it in a couple of places.  Building etc seems to still
  work, but I haven't tried building the documentation.

- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
  stuff was moved from -generic to -linux after the branch was created.
  I think that is satisfactorily glued back together now.

- Regtests: although this appears to work, no .out files appear, which
  is strange, and makes it hard to diagnose regtest failures.  In
  particular memcheck/tests/x86/scalar.stderr.exp remains in a 
  conflicted state.

- amd64 is broken (slightly), and ppc32 will be unbuildable.  I'll
  attend to the former shortly.
