The call to local_timer_register is hidden behind an #ifdef, which
turns the armada_370_xp_local_timer_ops into a potentially unused
variable, causing this warning:
time-armada-370-xp.c:208:31: warning: 'armada_370_xp_local_timer_ops' defined but not used [-Wunused-variable]
static struct local_timer_ops armada_370_xp_local_timer_ops __cpuinitdata = {
^
Since local_timer_register() itself doesn't do anything, just removing
the #ifdef makes the code look nicer and gets rid of the warning.

I thought this issue was kind of fixed by the patch
"clocksource: time-armada-370-xp: Divorce from local timer API" from Stephen Boyd.
But I can't find it in linux-next so maybe it has not been pulled, so in this case
you can also add my

The pull request is blocked on Thomas responding about
timers/core being a stable branch. We may just have to wait until
timers/core goes in before Arnd and Olof can take it in.

These are selected by omap4 but used in common omap4/5
SMP code, so building an omap5-only kernel is actually
broken without this patch.

The zynq platform code only supports DT based booting, so we
should use DT_MACHINE_START rather than MACHINE_START.

If we build a kernel with CONFIG_ARCH_OMAP2PLUS enabled but all of the
individual SoCs disabled, we run into a large number of link errors
because if incorrect dependencies:

We can avoid this if we make CONFIG_ARCH_OMAP2PLUS a silent option that
gets enabled any time that one of the SoC versions is enabled.

Hi,
I think this broke multi_v7_defconfig in last night's linux-next, due
to TI_PRIV_EDMA no longer being selected. Looks like you missed it
when moving the options around:

Some OMAP SoCs use this function while others do not, and that
causes a warning when building multi_v7_defconfig. Marking the
function __maybe_unused silences the harmless warning without the
need to add complex #ifdef logic.

With the new linux/reboot.h header file dependency added, we can no
longer build ixp4xx. The easiest way to avoid that is to remove the
inclusion of mach/hardware.h from mach/timex.h, which does not need
that header anyway.
