Subject: [PATCH 12/12] x86/compat: Separate ia32 and x32 compat ABIs
Date: Mon, 22 Jun 2015 07:55:21 -0400 [thread overview]
Message-ID: <1434974121-32575-13-git-send-email-brgerst@gmail.com> (raw)
In-Reply-To: <1434974121-32575-1-git-send-email-brgerst@gmail.com>
The x32 ABI is now independent of the ia32 compat ABI. Common code is
now conditional on CONFIG_COMPAT, but unshared code like syscall entry,
signal handling, and the VDSO are under separate config options.
