Teach the generic arch_get_unmapped_area(_topdown) code to call the
page colouring code.
What tree is that against? I cannot find x86 page colouring code in next
or mainline.
This is against mainline.
See align_addr in arch/x86/kernel/sys_x86_64.c and the
call sites in arch_get_unmapped_area(_topdown).
On certain AMD chips, Linux tries to get certain
allocations aligned to avoid cache aliasing issues.
