[x86-64 psABI] RFC: Extend x86-64 psABI to support x32

[H.J. Lu]

Hi,

Support for the x32 psABI:

http://sites.google.com/site/x32abi/

is added in Linux kernel 3.4-rc1.  X32 uses the ILP32 model for x86-64
instruction set with size of long and pointers == 4 bytes.  X32 is
already supported in GCC 4.7.0 and binutils 2.22.  I am now working
to integrate x32 support into GLIBC 2.16 and GDB 7.5   Here is a
patch to extend x86-64 psABI for x32.  Any comments?

Thanks.
