crashkernel allocation failure #1

Hi,

The kexec crash kernel area allocation code does some effort to move the images (i.e. kernel+initrd) out of the way, so the crashkernel area can be allocated at the default location (@16m).

In case initial_images_end is not page aligned a single page in the middle of the crash kernel area is leaked though, making the whole move effort fail.

The attached patch fixed that by rounding up initial_images_end to the next page boundary.

please apply,
Gerd
