Re: [PULL kvm-unit-tests] gitlab MR requested

Hi email readers,

I forgot to copy the gitlab MR description - copied below. (I need to
figure out how to better deal with this gitlab+email workflow.)

  This MR is a collection of fixes and improvements found while testing
  in different environments and also by code inspection. Some issues were
  found when experimenting with target-efi. Additionally, as preparation
  for target-efi, libfdt has been updated, which includes the need for a
  few more string functions being added to kvm-unit-test's libc, as well
  as some compiler builtin support to support those string functions.
  Finally, also in preparation for target-efi, we improve support for
  setting our "earlycon" (we want printf to work very early) and we
  explicitly zero the BSS and thread-info.

Thanks,
drew
