Subject: [PATCH] [PATCH] x86_64 ia32 vDSO: use VM_ALWAYSDUMP

This patch fixes ia32 core dumps on x86_64 to include just one phdr for the
vDSO vma.  Currently it writes a confused format with two phdrs for the
address, one without contents and one with.  This patch removes the
special-case core writing macros for the ia32 vDSO.  Instead, it uses
VM_ALWAYSDUMP in the vma.  This changes core dumps so they no longer include
the non-PT_LOAD phdrs from the vDSO, consistent with fixed native i386 core
dumps.
