* [S390] support XZ compressed kernelHeiko Carstens2011-03-152-1/+10
| | | | | | | Add support for XZ compressed kernel. Same as on x86 and sh. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] correct ipl parameter block safe guardMartin Schwidefsky2011-02-171-2/+3
| | | | | | | | | | 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.

* [S390] fix boot failures with compressed kernelsMartin Schwidefsky2010-03-241-4/+4
| | | | | | | | | 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 Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

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. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
