The generic atomic64 support came in 2009 to support the perf subsystem with the expectation that all architectures would implement atomic64 support. Since then, other optional parts of the generic kernel have also come to expect atomic64 support. This patch enables generic atomic64 support for C6X architecture.

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.

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

|
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.

Usually the pointer transfer from user space is checked to see if its

Say N here to disable that check to improve the performance.
