x86: Move is_ia32_task to asm/thread_info.h from asm/compat.h

ef334a20 · Srikar Dronamraju <[email protected]> · 2012-03-13 19:33:03 +05:30

is_ia32_task() is useful even in !CONFIG_COMPAT cases - utrace will
use it for example. 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.
