Subject: [PATCH 1/3] memblock tests: fix undefined reference to `early_pfn_to_nid'

commit 6a9531c3a880 ("memblock: fix crash when reserved memory is not
added to memory") introduce the usage of early_pfn_to_nid, which is not
defined in memblock tests.

The original definition of early_pfn_to_nid is defined in mm.h, so let
add this in the corresponding mm.h.

Subject: [PATCH 3/3] memblock tests: fix undefined reference to `BIT'

commit 772dd0342727 ("mm: enumerate all gfp flags") define gfp flags
with the help of BIT, while gfp_types.h doesn't include header file for
the definition. This through an error on building memblock tests.

Let's include linux/bits.h to fix it.

Subject: [PATCH 2/3] memblock tests: fix undefined reference to `panic'

commit e96c6b8f212a ("memblock: report failures when memblock_can_resize
is not set") introduced the usage of panic, which is not defined in
memblock test.

Let's define it directly in panic.h to fix it.

Andrew,

I can take these via memblock tree, what is your preference?

I'm seeing no conflicts at this time, so go for it.
