Patch from John S Gwynne <jsg@donet.com> for malloctest. His comments:

Browse Source 
I have a few patches for the efi332 bsp. If you let me know when you
  expect the next snapshot release, I will try to have them to you
  before then. Also, the malloctest has some problems that I would think
  would prevent it from running on almost any platform. I have enclose
  patches below to fix (1) Task_id and Task_name dimensioning, (2) end
  of test message, (3) the amount of memory malloc'ed, and (4) retry on
  unsuccessful (out of memory) molloc's.
