s390: fix linker script for 31 bit builds

2012-10-28T17:14:13+00:00

commit c985cb37f1b39c2c8035af741a2a0b79f1fbaca7 upstream.

Because of a change in the s390 arch backend of binutils (commit 23ecd77
"Pick the default arch depending on the target size" in binutils repo)
31 bit builds will fail since the linker would now try to create 64 bit
binary output.
Fix this by setting OUTPUT_ARCH to s390:31-bit instead of s390.
Thanks to Andreas Krebbel for figuring out the issue.

Fixes this build error:

  LD      init/built-in.o
s390x-4.7.2-ld: s390:31-bit architecture of input file
 `arch/s390/kernel/head.o' is incompatible with s390:64-bit output

[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.
