and is kernel indenpendent. It is separate from struct ucontext
defined in kernel header files.

Add x32 wordsize.h.
2011-11-21 H.J. Lu <hongjiu.lu@intel.com>
* sysdeps/x86_64/bits/wordsize.h: Moved to ...
* sysdeps/x86_64/64/bits/wordsize.h: Here.
(__WORDSIZE_COMPAT32): Removed.
* sysdeps/x86_64/x32/bits/wordsize.h: New.
Since wordsize-32 and wordsize-64 in sysdeps/x86_64/x32/Implies
and sysdeps/x86_64/64/Implies put sysdeps/wordsize-32/bits/wordsize.h
and sysdeps/wordsize-64/bits/wordsize.h before
sysdeps/x86_64/x32/bits/wordsize.h, we add
sysdeps/x86_64/64/bits/wordsize.h and sysdeps/x86_64/x32/bits/wordsize.h
to make sure that the proper wordsize.h is used.
Since we added sysdeps/unix/sysv/linux/x86_64/bits/utmp.h and
sysdeps/unix/sysv/linux/x86_64/bits/utmpx.h to support x32, there
is no need to define __WORDSIZE_COMPAT32 anymore.
