*	ARM: 8641/1: treewide: Replace uses of virt_to_phys with __pa_symbol	Florian Fainelli	2017-02-28	2	-2/+2
\| \| \| \| \| \| \| \| \| \| \|	All low-level PM/SMP code using virt_to_phys() should actually use __pa_symbol() against kernel symbols. Update code where relevant to move away from virt_to_phys().

*	ARM: tango: fix CONFIG_HOTPLUG_CPU=n build	Arnd Bergmann	2016-07-07	1	-3/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Building with CONFIG_HOTPLUG_CPU disabled fails for mach-tango: include/linux/stddef.h:7:14: error: excess elements in struct initializer [-Werror] #define NULL ((void *)0) arch/arm/mach-tango/platsmp.c:48:15: note: in expansion of macro 'tango_cpu_kill' .cpu_kill = tango_cpu_kill, the problem as that the .cpu_kill and .cpu_die struct members are unavailable and we must not try to assign them in this configuration. Hiding the two (as all other platforms do too) lets us get rid of the #else clause as well. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Olof Johansson <olof@lixom.net>

*	ARM: tango: use "depends on" instead of "if" after prompt	Masahiro Yamada	2016-02-01	1	-1/+2
\| \| \| \| \| \| \| \| \| \|	This platform was recently added, so missed the global fixup by commit e32465429490 ("ARM: use "depends on" for SoC configs instead of "if" after prompt"). Fix it now.

*	ARM: tango4: Initial platform support	Marc Gonzalez	2015-12-23	5	-0/+59
	Support Sigma Designs ARM-based (specifically, Cortex-A9 MPCore r3p0) Tango4 "Secure Media Processor" platforms: smp8756, smp8758, smp8759 (8756 is single-core, the latter are dual-core). Note: 8758 vs 8759: same chip, different package. Support for older MIPS-based platforms can be found elsewhere: https://github.com/mansr/linux-tangox Signed-off-by: Marc Gonzalez <marc_gonzalez@sigmadesigns.com> Reviewed-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>
