Subject: [PATCH for 2.6.19] [2/9] x86_64: Fix PTRACE_[SG]ET_THREAD_AREA regression with ia32 emulation.


ptrace(PTRACE_[SG]ET_THREAD_AREA) calls from ia32 code
should be passed onto the x86_64 implementation.

The default case in sys32_ptrace used to call to sys_ptrace(), but is 
now EINVAL.  This patch fixes a regression caused by that changed.
