Based on an original patch from Cédric Le Goater <clg@fr.ibm.com> found at: legoater@c0f9cc7 and modified by me to store uncompressed image in memory and thus not require a temporary file. Signed-off-by: Robert Lippert <rlippert@google.com>

Alternative solution here #8 turns out the actual problem is with how we work out the entry point of the image that we're kexecing into. With that fixed we can rely on the decompression code in the zImage itself rather than extracting the built-in vmlinux. This is handy since we now support XZ compression in addition to gzip and it's less code to cart around. |

Based on an old patch provided by @legoater.
Lack of zImage boot support in off-the-shelf openpower boxes has been a recent pain point for us so we'd like to get this in upstream if possible.
We've been using a variant of this patch internally for a long time without any issues :)
