ARM: 7480/1: only call smp_send_stop() on SMP

commit c5dff4ffd327088d85035bec535b7d0c9ea03151 upstream.

On reboot or poweroff (machine_shutdown()) a call to smp_send_stop() is
made (to stop the others CPU's) when CONFIG_SMP=y.

arch/arm/kernel/process.c:

void machine_shutdown(void)
{
 #ifdef CONFIG_SMP
       smp_send_stop();
 #endif
}

smp_send_stop() calls the function pointer smp_cross_call(), which is set
on the smp_init_cpus() function for OMAP processors.

arch/arm/mach-omap2/omap-smp.c:

void __init smp_init_cpus(void)
{
...
	set_smp_cross_call(gic_raise_softirq);
...
}

But the ARM setup_arch() function only calls smp_init_cpus()
if CONFIG_SMP=y && is_smp().

arm/kernel/setup.c:

void __init setup_arch(char **cmdline_p)
{
...
 #ifdef CONFIG_SMP
	if (is_smp())
		smp_init_cpus();
 #endif
...
}

Newer OMAP CPU's are SMP machines so omap2plus_defconfig sets
CONFIG_SMP=y. Unfortunately on an OMAP UP machine is_smp()
returns false and smp_init_cpus() is never called and the
smp_cross_call() function remains NULL.

If the machine is rebooted or powered off, smp_send_stop() will
be called (since CONFIG_SMP=y) leading to the following error:

Add a check so smp_cross_call() is only called when there is more than one CPU on-line.

ARM: 7559/1: smp: switch away from the idmap before updating init_mm.mm_count

commit 5f40b909728ad784eb43aa309d3c4e9bdf050781 upstream.

When booting a secondary CPU, the primary CPU hands two sets of page
tables via the secondary_data struct:

	(1) swapper_pg_dir: a normal, cacheable, shared (if SMP) mapping
	    of the kernel image (i.e. the tables used by init_mm).

	(2) idmap_pgd: an uncached mapping of the .idmap.text ELF
	    section.

The idmap is generally used when enabling and disabling the MMU, which
includes early CPU boot. In this case, the secondary CPU switches to
swapper as soon as it enters C code:

	struct mm_struct *mm = &init_mm;
	unsigned int cpu = smp_processor_id();

	/*
	 * All kernel threads share the same mm context; grab a
	 * reference and switch to it.
	 */
	atomic_inc(&mm->mm_count);
	current->active_mm = mm;
	cpumask_set_cpu(cpu, mm_cpumask(mm));
	cpu_switch_mm(mm->pgd, mm);

This causes a problem on ARMv7, where the identity mapping is treated as
strongly-ordered leading to architecturally UNPREDICTABLE behaviour of
exclusive accesses, such as those used by atomic_inc.

This patch re-orders the secondary_start_kernel function so that we
switch to swapper before performing any exclusive accesses.

ASoC: dapm: Fix _PRE and _POST events for DAPM performance improvements

commit 0ff97ebf0804d2e519d578fcb4db03f104d2ca8c upstream.

Ever since the DAPM performance improvements we've been marking all widgets
as not dirty after each DAPM run. Since _PRE and _POST events aren't part
of the DAPM graph this has rendered them non-functional, they will never be
marked dirty again and thus will never be run again.

Fix this by skipping them when marking widgets as not dirty.

ARM: Remove __ARCH_WANT_INTERRUPTS_ON_CTXSW on pre-ARMv6 CPUs

This patch removes the __ARCH_WANT_INTERRUPTS_ON_CTXSW definition for
ARMv5 and earlier processors. On such processors, the context switch
requires a full cache flush. To avoid high interrupt latencies, this
patch defers the mm switching to the post-lock switch hook if the
interrupts are disabled.
