Commit 1e4c64b71c9b ("mm/memblock: Add "reserve_mem" to reserved named
memory at boot up") introduce usage of isspace().
Let's include <linux/ctype.h> in kernel.h to fix this.

Commit 1e4c64b71c9b ("mm/memblock: Add "reserve_mem" to reserved named
memory at boot up") introduce the usage of memparse(), which is not
defined in memblock test.
Add the definition and link it to fix the build.

Currently we have two test suits define its own init.h. This is a little
redundant.
Let's create a init.h in common include directory and merge these two
into it.

In kernel code, linkage.h includes export.h. Let's sync with kernel.
This is a preparation for move init.h in common include directory.

In kernel code, memory_hotplug.h is included in mmzone.h instead of in

commit 23baf831a32c ("mm, treewide: redefine MAX_ORDER sanely") has
changed the definition of MAX_ORDER to be inclusive. This has caused
issues with code that was not yet upstream and depended on the previous
definition.
To draw attention to the altered meaning of the define, rename MAX_ORDER
to MAX_PAGE_ORDER.

MAX_ORDER currently defined as number of orders page allocator supports:
user can ask buddy allocator for page order between 0 and MAX_ORDER-1.
This definition is counter-intuitive and lead to number of bugs all over
the kernel.
Change the definition of MAX_ORDER to be inclusive: the range of orders
user can ask from buddy allocator is 0..MAX_ORDER now.

kmemleak_alloc_phys()
Patch series "mm: kmemleak: store objects allocated with physical address
separately and check when scan", v4.
The kmemleak_*_phys() interface uses "min_low_pfn" and "max_low_pfn" to
check address. But on some architectures, kmemleak_*_phys() is called
before those two variables initialized. The following steps will be
taken:
1) Add OBJECT_PHYS flag and rbtree for the objects allocated
with physical address
2) Store physical address in objects if allocated with OBJECT_PHYS
3) Check the boundary when scan instead of in kmemleak_*_phys()
This patch set will solve:

This patch (of 4):
Remove the unused kmemleak_not_leak_phys() function. And remove the
min_count argument to kmemleak_alloc_phys() function, assume it's 0.
