Panic on kmemleak scan

[Vladimir Zapolskiy]

Hello Mike,

commit a7259df767 ("memblock: make memblock_find_in_range method private") [1]
invokes a kernel panic while running kmemleak on OF platforms with nomaped
regions, basically it's similar to an issue reported and fixed earlier by [2]:

  Unable to handle kernel paging request at virtual address ffff000021e00000
  [...]
    scan_block+0x64/0x170
    scan_gray_list+0xe8/0x17c
    kmemleak_scan+0x270/0x514
    kmemleak_write+0x34c/0x4ac

I believe it would be a trivial problem to correct for you, thank you in
advance!
