Subject: [PATCH] ARM: fix CONFIG_VIRT_TO_BUS handling
Date: Wed, 13 Mar 2013 16:43:48 +0000 [thread overview]
Message-ID: <201303131643.48506.arnd@arndb.de> (raw)
887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS"
and 4febd95a8 "Select VIRT_TO_BUS directly where needed" from
Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is
selected, while my own a5d533ee0 "ARM: disable virt_to_bus/
virt_to_bus almost everywhere" was merged at the same time and
changed which platforms select it on ARM.
The result of this conflict was that we again see CONFIG_VIRT_TO_BUS
on all ARM systems. This patch fixes up the problem and removes
CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.

I'd like to merge this one through the arm-soc tree as a 3.9 bug fix
unless there are objections.
