I have spent some time and have gotten my relocatable kernel patches

Could all of the people who care take a look and test this out

Hi Eric,

Currently I am testing your patches on i386. With CONFIG_RELOCATABLE=y
kernel boots fine and kexec also works.

But my kernel hangs on kexec on panic case. It hangs early in
decompress_kernel(). Kernel hangs at following condition.

+ if (((u32)output - CONFIG_PHYSICAL_START) & 0x3fffff)
+ error("Destination address not 4M aligned");

I have reserved 64MB at 16M and kernel is loaded at 16M.

I had expected that I would get "Destination address not 4M aligned" on
serial console but did not happen. Had to put outb() to get to this point.

Will look more into it.

Thanks
Vivek
