Title:
  -kernel option broken for some multiboot kernels

Status in QEMU:
  Fix Released

Bug description:
  When using the -kernel option QEMU fails with "Error while fetching
  elf kernel from rom" when the ELF file contains a segment with a file
  size of 0. This is typical for segments containing only a .bss
  section.

  rom_copy (hw/core/loader.c) fails to load roms (elf segments in this
  case) with a datasize of 0 - it skips the rom because rom->data is
  NULL. This bug is introduced by commit
  d60fa42e8bae39440f997ebfe8fe328269a57d16 'Save memory allocation in
  the elf loader' and affects QEMU v1.5.0 and later.

  I'll send a patch for this bug to qemu-devel.
