s390: remove 31 bit support

2015-03-25T10:49:33+00:00

Remove the 31 bit support in order to reduce maintenance cost and effectively remove dead code. Since a couple of years there is no distribution left that comes with a 31 bit kernel. The 31 bit kernel also has been broken since more than a year before anybody noticed. In addition I added a removal warning to the kernel shown at ipl for 5 minutes: a960062e5826 ("s390: add 31 bit warning message") which let everybody know about the plan to remove 31 bit code. We didn't get any response. Given that the last 31 bit only machine was introduced in 1999 let's remove the code. Anybody with 31 bit user space code can still use the compat mode.

s390/comments: unify copyright messages and remove file names

2012-07-20T09:15:04+00:00

Remove the file name from the comment at top of many files. In most cases the file name was wrong anyway, so it's rather pointless. Also unify the IBM copyright statement. We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go. Signed-off-by: Heiko Carstens

Add missing GFP flag to memory allocations. The part in cio only changes a comment. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] Replace ENOTSUPP usage with EOPNOTSUPP

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

ENOTSUPP is not supposed to leak to userspace so lets just use EOPNOTSUPP everywhere. Doesn't fix a bug, but makes future reviews easier. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] dcssblk: add >2G DCSSs support and stacked contiguous DCSSs support.

2008-10-10T19:33:57+00:00

The DCSS block device driver is modified to add >2G DCSSs support and allow a DCSS block device to map to a set of contiguous DCSSs. The extmem code is also modified to use new Diagnose x'64' subcodes for >2G DCSSs. Signed-off-by: Hongjie Yang Signed-off-by: Martin Schwidefsky

[S390] Convert to SPARSEMEM & SPARSEMEM_VMEMMAP

2008-04-30T11:38:48+00:00

Convert s390 to SPARSEMEM and SPARSEMEM_VMEMMAP. We do a select of SPARSEMEM_VMEMMAP since it is configurable. This is because SPARSEMEM without SPARSEMEM_VMEMMAP gives us a hell of broken include dependencies that I don't want to fix. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky
