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.

[S390] cpcmd: fix inline assembly usage.

2007-10-12T14:13:09+00:00

After assigning values to specific registers memset was called. This
may clobber the contents of the used registers.
To solve this extract the two used inline assemblies into small
functions that don't call any functions.

[S390] cpcmd with vmalloc addresses.

2007-02-05T20:16:54+00:00

Change the bounce buffer logic of cpcmd. diag8 needs _real_ memory below
2GB. Therefore vmalloced data does not work. As the data might cross a
page boundary, we cannot use virt_to_page either. The solution is to use
virt_to_page only in the check for a bounce buffer.

There was a redundant check for response==NULL. response < 2GB contains
this check as well.

I also removed the rlen==0 check, since rlen=0 and response!=NULL would
be a caller bug and response==NULL is already checked.

[S390] cpcmd <-> __cpcmd calling issues

2006-12-04T14:40:30+00:00

In case of reipl cpcmd gets called when all other cpus are not running
anymore. To prevent deadlocks change __cpcmd so that it doesn't take
any locks and call cpcmd or __cpcmd, whatever is correct in the current
context.

[S390] Inline assembly cleanup.

2006-09-28T14:56:43+00:00

Major cleanup of all s390 inline assemblies. They now have a common
coding style. Quite a few have been shortened, mainly by using register
asm variables. Use of the EX_TABLE macro helps  as well. The atomic ops,
bit ops and locking inlines new use the Q-constraint if a newer gcc
is used.  That results in slightly better code.

Thanks to Christian Borntraeger for proof reading the changes.

[PATCH] s390: cleanup Kconfig

2006-01-06T16:33:53+00:00

Sanitize some s390 Kconfig options.  We have ARCH_S390, ARCH_S390X,
ARCH_S390_31, 64BIT, S390_SUPPORT and COMPAT.  Replace these 6 options by
S390, 64BIT and COMPAT.

[PATCH] broken inline asm on s390 (misuse of labels)

2005-08-24T01:43:44+00:00

use of explicit labels in inline asm is a Bad Idea(tm), since gcc can
decide to inline the function in several places.  Fixed by use of 1f/f:
instead of .Lfitsin/.Lfitsin:
