BSYM macro is only needed for assembly files and its usage in c files is
wrong, so remove it. The linker will correctly set bit 0 for Thumb2

Several platforms are now using the memblock_alloc+memblock_free+
memblock_remove trick to obtain memory which won't be mapped in the
kernel's page tables. Most platforms do this (correctly) in the
->reserve callback. However, OMAP has started to call these functions
outside of this callback, and this is extremely unsafe - memory will
not be unmapped, and could well be given out after memblock is no
longer responsible for its management.
So, provide arm_memblock_steal() to perform this function, and ensure
that it panic()s if it is used inappropriately. Convert everyone
over, including OMAP.
As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot
with this change. Mark this option as BROKEN and make it depend on
BROKEN. OMAP needs to be fixed, or 137d105d50 (ARM: OMAP4: Fix
errata i688 with MPU interconnect barriers.) reverted until such
time it can be fixed correctly.

A significant part of the changes for these two platforms went into
power management, so they are split out into a separate branch.

The i.MX6 Quad SoC will work without the l2x0 L2 cache controller
support built into the kernel, so this patch removes the dependency
on CACHE_L2X0.
This makes the l2x0 support optional, so that it can be turned off
when desired for debugging purposes etc.
Since SOC_IMX6Q already depends on ARCH_IMX_V6_V7 and
ARCH_IMX_V6_V7 selects MIGHT_HAVE_CACHE_L2X0, there is no need to
select that option explicitly from SOC_IMX6Q.
Thanks to Shawn Guo for this suggestion. [1]

Making SMP depend on (huge list of MACH_ and ARCH_ configs) is
bothersome to maintain and likely to lead to merge conflicts.
This patch moves the knowledge of which platforms are SMP-capable
to the individual machines. To enable this, a new HAVE_SMP config
option is introduced to allow machines to indicate that they can
run in a SMP configuration.

When gpio core dynamically allocate gpio number for a port, it starts
from the end of the total range, 0 ~ ARCH_NR_GPIOS. That said, the
earlier a port gets probed, the bigger gpio number it gets assigned.
To match this, the irq_base for gpio should be assigned from
'MXC_GPIO_IRQ_START + ARCH_NR_GPIOS' decreasingly.

The of_irq_init() expects the callback passed by .data of of_device_id
return 'int' instead of 'void'. This patch fixes it to have
irq_init_cb() return the correct value, and in turn have the secondary
interrupt controller (gpio in this case) initialized properly and also
eliminate the error message 'of_irq_init: children remain, but no
parents' which was overlooked before.
