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

From: Stephen Boyd
Date: Mon Mar 18 2013 - 14:29:26 EST


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.
