The 'output' variable is passed from decompress_kernel to
check_ipl_parmblock before it is initialized. That disables the
safe guard against the overwrite of the ipl parameter block.
Fix this by passing the correct value to check_ipl_parmblock.

Fix two bugs with the kernel image compression:
1) reset the bss section of the compressed vmlinux
2) clear the high half of the registers for 64 bit early enough
for the decompression step

Add the "bzImage" compile target and the necessary code to generate
compressed kernel images. The old style uncompressed "image" target
is preserved, a simple make will build them both.
