Subject: [PATCH 1/3] ARM: Clear IDIVT hwcap if CONFIG_ARM_THUMB=n
Date: Tue, 12 Mar 2013 18:31:59 -0700	[thread overview]
Message-ID: <1363138321-27849-2-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1363138321-27849-1-git-send-email-sboyd@codeaurora.org>

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.
