Subject: [PATCH] fix Subject: [PATCH] kexec: Add quick kexec support
Add quick kexec option -q and flags.
In normal kexec, relocating kernel may cost 5 ~ 10 seconds, to
copy all segments from vmalloced memory to kernel boot memory,
because of disabled mmu.
We introduce quick kexec to save time of copying memory as above,
just like kdump(kexec on crash), by using reserved memory.
We also add this support in syscall kexec_load of linux kernel
through flags of KEXEC_QUICK.
