Subject[PATCH 1/2] x86: Move is_ia32_task to asm/thread_info.h from asm/compat.h
From: Srikar Dronamraju <srikar@linux.vnet.ibm.com>

is_ia32_task is useful even in !CONFIG_COMPAT cases. Hence move it
to a more generic file asm/thread_info.h

Also now is_ia32_task returns true if CONFIG_X86_32 is defined.
