[PATCH 0/2] Add support for kexec-hardboot to Nexus 7 kernel

I am hoping to use kexec in my multi-boot tool for Nexus 7[1], since it would
make booting from (not only) USB drive much easier. These two patches are
the absolute minimum which is needed for the "guest" kernel to run when
it is kexecd'.

I will understand if these patches get rejected - they are simply useless
for normal user, but I am trying to get them into Ubuntu's kernel because
they are pretty small, they are touching relatively stable parts of kernel
and because they would make it much easier for me - if I were to release
modified version of kernel just for multi-boot, I would have to disable kernel
updates from Ubuntu and keep the modified version updated - all that just
because of 78 lines of code.
