+ 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.
+
+ We make sure that we can allocate upto a HugePage size for each configuration.
+ Hence we have :
+ MAX_ORDER = (PMD_SHIFT - PAGE_SHIFT) + 1 => PAGE_SHIFT - 2
+
+ However for 4K, we choose a higher default value, 11 as opposed to 10, giving us
+ 4M allocations matching the default size used by generic code.

handled appropriately by the kernel.
- If you also enabled CONFIG_ARM64_64K_PAGES, please be aware that you
- will only be able to execute AArch32 binaries that were compiled with
- 64k aligned segments.
+ If you use a page size other than 4KB (i.e, 16KB or 64KB), please be aware
+ that you will only be able to execute AArch32 binaries that were compiled
+ with page size aligned segments.
If you want to execute 32-bit userspace applications, say Y.
