Note:
Kernel Developers: I would like to ask you to merge this patch to your kernels, because it is essential part of MultiROM (MR) - it allows MR to boot any kernel without changing the boot partition. I realize that it is no small request, but the patch is not big, touches relatively stable parts of kernel and should not cause any problems outside its intended function.
The Patch:
You'll need to cherry pick a total of 5 commits (if anyone feels like squashing them to help me out, feel free to link me to it).
Cherry-pick against: http://ift.tt/21fxp7D on the branch 'mm'.

User-space Kexec binary: here (you'll need to extract the zip, and it will be in 'multirom/kexec')
A guide to use the binary is coming.
Authors:
- This patch was made by Mike Kasick for Samsung Epic 4G.
- Tassadar built on this patch, and partially rewrote it to support the Nexus 4, 5, and 6.
- Zhuowei Zhang rewrote the patch from scratch for arm64.
- Myself for maintaining MultiROM for the 6P, and managing the patch.

Related defconfig options, and their explanations:
Code:
CONFIG_KEXEC=y # Enables the Kexec SysCall to allow loading the new 'secondary' kernel into memory
CONFIG_KEXEC_HARDBOOT=y # Enables the HardBoot flag, which allows 'cold-booting' a new kernel
# CONFIG_ATAGS_PROC is not set # Prevents potential atags related discrepancies, this must be either removed or commented out
CONFIG_PROC_DEVICETREE=y # Allows us to read out the kernel config, and tell that the kernel has all the necessary configs enabled (read out from /proc/config.gz) A guide to use the binary is coming.
