Subject: [PATCHv2 1/3] ARM: Clear IDIVT hwcap if CONFIG_ARM_THUMB=n

From: [email-masked] (Stephen Boyd)
Date: Mon, 18 Mar 2013 11:28:55 -0700

Don't advertise support for the SDIV/UDIV thumb instructions if
the kernel is not compiled with support for thumb userspace. This
is in line with how we remove the THUMB hwcap in these
configurations.
