3c030beabf ARM: CPU hotplug: move cpu_killed completion to core code
We always need to wait for the dying CPU to reach a safe state before
taking it down, irrespective of the requirements of the platform.
Move the completion code into the ARM SMP hotplug code rather than
having each platform re-implement this.

2c0136dba4 ARM: SMP: consolidate trace_hardirqs_off() into common SMP code
All platforms call trace_hardirqs_off() in their secondary startup code,
so move this into the core SMP code - it doesn't need to be in the
per-platform code.

05c74a6cbc ARM: SMP: consolidate the common parts of smp_prepare_cpus()
There is a certain amount of smp_prepare_cpus() which doesn't belong
in the platform support code - that is, code which is invariant to the
SMP implementation.  Move this code into arch/arm/kernel/smp.c, and
add a platform_ prefix to the original function.

8975b6c0fd ARM: SMP: Clean up ncores sanity checks
scu_get_core_count() never returns zero cores, so we don't need to
check and correct if ncores is zero.

Tegra was missing the check against NR_CPUS, leading to a potential
bitfield overflow if this becomes the case.

ff2e27ae0b ARM: GIC: consolidate gic_cpu_base_addr to common GIC code
Every architecture using the GIC has a gic_cpu_base_addr pointer for
GIC 0 for their entry assembly code to use to decode the cause of the
current interrupt.  Move this into the common GIC code.

384895330e ARM: GIC: Remove MMIO address from gic_cpu_init, rename to gic_secondary_init
We don't need to re-pass the base address for the CPU interfaces to the
GIC for secondary CPUs, as it will never be different from the boot CPU
- and even if it was, we'd overwrite the boot CPU's base address.

Get rid of this argument, and rename to gic_secondary_init().

85140ad591 ARM: S5PV310: Add irq_mask to handle combiner irqs properly
The 4 combiner groups use same registers to handle the interrupt.
In previous implementation, the whole registers are checked to find
which interupt is occurred and thus interrupt in other groups can

This patch adds Samsung SMDKC210 board support file. The SoC

And because composition of SMDKC210 and SMDKV310 differs, need
SMDKC210 with SMDKV310.

6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.
