  Branch:      sys/kern  RELENG_2_2
  Modified:    sys/kern  kern_exec.c
  Log:
  Fixed two bugs that came into kern_exec just after the 2.2.1 release:
  
  1) I wasn't assuring that the file size was large enough for the data
     to be contained in a FS block. Calling bread for a block when the
     data is in a fragment causes BAD things to happen, including file
     corruption.
  2) I was not passing in a residual pointer to vn_rdwr(), and this
     caused "slow" mode image header reads that were less than the
     page size to fail with EIO. I now get the residual and properly
     zero the tail of the image header buffer, too.
