Subject: [RFC PATCH] Make AT_VECTOR_SIZE_ARCH 2 for x86-32
Date: Mon, 8 Feb 2010 14:34:40 -0600 [thread overview]
Message-ID: <20100208203440.GA27389@us.ibm.com> (raw)
[ RFC: Am I on crack? ]
Both x86-32 and x86-64 with 32-bit compat use ARCH_DLINFO_IA32,
which defines two saved_auxv entries. But system.h only defines
AT_VECTOR_SIZE_ARCH as 2 for CONFIG_IA32_EMULATION, not for
CONFIG_X86_32. Fix that.
