The patch titled
x86_64 ia32 vDSO: define arch_vma_name
has been removed from the -mm tree. Its filename was
x86_64-ia32-vdso-define-arch_vma_name.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: x86_64 ia32 vDSO: define arch_vma_name
From: Roland McGrath <roland@xxxxxxxxxx>
This patch makes x86_64 define arch_vma_name for CONFIG_IA32_EMULATION. This
makes the ia32 vDSO mapping appear in /proc/PID/maps with "[vdso]" for ia32
processes, as it does on native i386.
