    Subject[PATCH 0/20] x86_64 Relocatable bzImage support (V4)
    Hi,

    Here is another attempt on x86_64 relocatable bzImage patches(V4). This
    patchset makes a bzImage relocatable and same kernel binary can be loaded
    and run from different physical addresses.

    As on now, this mainly helps distros who have to ship an extra kernel compiled
    for a different physical address to capture the kernel crash dump. This
    patchset will allow distros and kdump users to use production kernel itself
    as dump capture kernel and there is no need to ship/build an extra kernel.
    I am hopeful people will find other interesting usages down the line.

    Eric has done all the heavy weight lifting requird to make this patchset
    work. Last time I posted this patchset (V3), there were minor comments
    which I have taken care of. Following are the changes since V3.

    - Reduced the usage of _AC() macro to only shift operations, as per
    Andi's comment.
    - Restored the CONFIG_PHYSICAL_START option.
    - Fixed few bugs with suspend to disk code path.

    It would be good if these patches get into -mm so that it can undergo more
    testing. I have been testing them and these just work fine for me.

    Thanks
    Vivek
