Newer versions of the region registers also support dividing these
TCMs in two separate banks, so for example an 8KiB ITCM is divided
into two 4KiB banks with its own control registers. The idea is to
be able to lock and hide one of the banks for use by the secure

Linux XFS behaves as if an "osyncisdsync" option is used,

The kernel memory allocator divides physically contiguous memory
blocks into "zones", where each zone is a power of two number of

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.
