Subject: [PATCH 1/2] x86: Move is_ia32_task to asm/thread_info.h from asm/compat.h
Date: Tue, 13 Mar 2012 19:33:03 +0530 [thread overview]
Message-ID: <20120313140303.17134.1401.sendpatchset@srdronam.in.ibm.com> (raw)
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.
