[PATCH] kexec: reserve Bootmem fix for booting nondefault location kernel
This patch fixes a problem with reserving memory during boot up of a kernel
built for non-default location. Currently boot memory allocator reserves
the memory required by kernel image, boot allocaotor bitmap etc. It
assumes that kernel is loaded at 1MB (HIGH_MEMORY hard coded to 1024*1024).
But kernel can be built for non-default locatoin, hence existing
hardcoding will lead to reserving unnecessary memory. This patch fixes it.
