Raw Normal View History

[S390] dasd whitespace and other cosmetics. Dasd code cleanup: 1) remove white space, 2) remove the emacs override sections, and 3) use kzalloc instead of kmalloc. Signed-off-by: Horst Hummel <horst.hummel@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

s390/comments: unify copyright messages and remove file names 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 <heiko.carstens@de.ibm.com>

[PATCH] s390: 64 bit diag250 support Add support for diag 250 access to dasd devices for 64 bit kernels. In addition fix detach/attach for diag disks. The VM control block needs to get recreated by a call to mdsk_init_io.
