Mark Salter 0bd761e1b6 irq_domain/c6x: Convert c6x to use generic irq_domain support.
The C6X IRQ support was copied almost verbatim from the PowerPC virtual IRQ
code. The PowerPC code was used as the basis for generic irq_domain support,
so this patch mostly copies what what done to arch/powerpc by Grant Likely
in his irq_domain patch series.

config C6X_BIG_KERNEL
bool "Build a big kernel"
help
The C6X function call instruction has a limited range of +/- 2MiB.
This is sufficient for most kernels, but some kernel configurations
with lots of compiled-in functionality may require a larger range
for function calls. Use this option to have the compiler generate
function calls with 32-bit range. This will make the kernel both
larger and slower.
If unsure, say N.

help
On some architectures there is currently no way for the boot loader
to pass arguments to the kernel. For these architectures, you should
supply some command-line options at build time by entering them
here.
config CMDLINE_FORCE
bool "Force default kernel command string"
depends on CMDLINE_BOOL
default n
help
Set this to have arguments from the default kernel command string
override those passed by the boot loader.
config CPU_BIG_ENDIAN
bool "Build big-endian kernel"
default n
help
Say Y if you plan on running a kernel in big-endian mode.
Note that your board must be properly built and your board
port must properly enable any big-endian related features
of your chipset/board/processor.
config FORCE_MAX_ZONEORDER
int "Maximum zone order"
default "13"
help
The kernel memory allocator divides physically contiguous memory
blocks into "zones", where each zone is a power of two number of
pages. This option selects the largest power of two that the kernel
keeps in the memory allocator. If you need to allocate very large
blocks of physically contiguous memory, then you may need to
increase this value.
This config option is actually maximum order plus one. For example,
a value of 11 means that the largest free memory block is 2^10 pages.

help
Usually the pointer transfer from user space is checked to see if its
address is in the kernel space.
Say N here to disable that check to improve the performance.
