Page affinity block can be used to resolve the VIPT aliasing problem.
|
|
It should be set to `1ul << ((index + block) - page_offset)` in this case.
|

You could also exploit this as a tunning for cache coloring.

For example, A value of 11 means the maximum chunk of contiguous memory
|
|
allocatable by page system is 2^(11 + ARCH_PAGE_BITS - 1) Bytes.
|
|
Large memory requirement can consume all system resource, and should
|
|
consider reserved memory instead to enhance system endurance.

Max order should at least satisfied usage by huge page.
