[S390] fix s390 assembler code alignments

2011-07-24T08:48:21+00:00

The alignment is missing for various global symbols in s390 assembly code.
With a recent gcc and an instruction like stgrl this can lead to a
specification exception if the instruction uses such a mis-aligned address.

Specify the alignment explicitely and while add it define __ALIGN for s390
and use the ENTRY define to save some lines of code.

[S390] correct ipl parameter block safe guard

2011-02-17T12:13:59+00:00

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 kernels

2010-03-24T10:49:54+00:00

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

[S390] add support for compressed kernels

2010-02-26T21:37:33+00:00

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.
