[S390] compile fix for latest binutils

2011-04-04T07:43:33+00:00

The latest binutils won't accept the stfl instruction with march=g5
which is the correct behaviour. Unfortunately head.S is assembled
with -march=g5 even if the target cpu is z900 or later. To get
31-bit kernels compiled again the easiest fix is to use the .insn
notation for the stfl instruction in head.S.

[S390] Add config option for z196 code generation.

2010-10-25T14:10:15+00:00

Add a kernel config option for the IBM zEnterprise 196. This will
produce faster code on newer compilers using the -march=z196 option.

[S390] initrd: change default load address

2010-08-09T16:12:54+00:00

Change default load address of the initrd in case of IPL from reader.
The new load address is directly behind the kernel image.
This way we can see immediatly if there are any problems with the code
which tries to rescue the initrd in case the bootmem bitmap would
overlap with the initrd.

[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.

[S390] codepage conversion of kernel parameter line

2010-02-26T21:37:32+00:00

Move the ebcdic to ascii conversion of the kernel parameter line from
head.S to early.c and convert the assembler code to C.

[S390] Cleanup struct _lowcore usage and defines.

2010-02-26T21:37:31+00:00

Use asm offsets to make sure the offset defines to struct _lowcore and
its layout don't get out of sync.
Also add a BUILD_BUG_ON() which checks that the size of the structure
is sane.
And while being at it change those sites which use odd casts to access
the current lowcore. These should use S390_lowcore instead.

[S390] Limit cpu detection to 256 physical cpus.
