end_request(int) turned to end_request(req, int); all old callers
are converted to end_request(CURRENT, value).  Now we can start
killing CURRENT/QUEUE - end_request() was the last obstacle to
that.

ditto for DEVICE_INTR/CLEAR_INTR.  do_mfm/do_acsi/do_hd/... are
explicitly declared in the drivers that use DEVICE_INTR stuff;
DEVICE_INTR/CLEAR_INTR is gone from blk.h.

#define DEVICE_NAME ... removed from the drivers that never use
that macro.

monstrous cascade of #ifdefs is gone from blk.h.  This is the first
step of cleanup - we move #define in question into the code that
includes blk.h (i.e. DEVICE_NR, DEVICE_NAME and DEVICE_INTR are
explicitly set by drivers).

->s_dev is switched to dev_t.  Everything that uses it uses it as
a number - i.e. all instances are either minor() or kdev_t_to_nr().

->j_dev is gone from reiserfs journal.  All its uses had been replaced
with use of ->j_dev_bd; it's simply not used anymore.

get_super() split in two functions - get_super(bdev) and
user_get_super(dev_t).  Callers that used get_super() to get superblock
by (dev_t) syscall argument switched to the latter; the rest had
block_device in question and switched to passing it.

ROOT_DEV converted to dev_t.  There's no reason for it to be kdev_t -
it's both used as a number and set as a number.

do_getattr() renamed to vfs_getattr(), exported and used by
loop.c and nfsd - both blindly accessed ->i_dev/->i_ino of
random inodes when they ought to be calling ->getattr() to
get that information.

misc gratitious kdev_t uses fixed (janitorial stuff - e.g. quota
patches had reintroduced kdevname(sb->s_dev) in places where we'd
switched to sb->s_id, etc.)

added bdev_read_only() - analog of is_read_only() using block_device.
Almost all callers of is_read_only() converted.

sget()/generic_shutdown_super() cleaned up; fixed error handling
in sget()

FS_NOMOUNT is gone, initialization for pseudo-filesystems
(bdev, pipe, sock) switched to use of a common helper.

compile fixes (missing includes + obvious fix in adfs/map.c)

fs/nfs/dir.c:

   - Call nfs_renew_times() when we deliberately create a negative dentry.
     or rename a file.

fs/nfs/inode.c:
  - Ensure that we initialize NFS_MTIME_UPDATE(inode).

  - If a directory's mtime changed due to some action on our part
    (file creation/deletion/...) don't force a dcache revalidation by
    changing NFS_MTIME_UPDATE(inode).

Fourth and last part of the s/390 update. Docu stuff.

Third patch of the s/390 update. Everything from drivers/s390. This patch
contains the main bunch of changes. Major changes are: 1) the restructured
dasd driver, 2) the new tape driver, 3) the start of the common io layer
rework, 4) the gpl'ed lcs driver and 5) the gpl'ed qdio layer

Second patch of the s/390 update. Contains all the include file changes in
include/asm-{s390,s390x}.

This first patch contains the changes to arch/{s390,s390x}

resume_kernel uses CPU_IDX but never uses GET_CPU_IDX to get the index.

  This is an issue when smp and preemption are both enabled.  I also
removed the unused GET_CURRENT_CPU_IDX.

James introduced bad bug which causes NULL pointer dereference as soon
as you'll try to use secondary head because of screen_base is not
initialized (it is initialized on wrong head).

Mike Kravetz pointed out that the set_cpus_allowed optimization he
suggested has a small but possible race condition wherein the system
could still be operating in the context of the task but it is not
running.  On top of this, the runqueue lock can be dropped in
load_balance and thus we can race and set task->cpu at a very unpleasant
time.

My solution is to just remove the optimization.

Apparently my understanding of C brace rules was blurred and there is a
thinko in kernel/capability.c - what we want is what the indention
reflects but what we get is an unconditional return of -EINVAL.

Define the for_each_lock macro and start replacing ugly special for loops
with it.  Rejig the interface between sys_flock and flock_lock_file to
always pass a struct file_lock rather than a command.  Eliminate some
gotos by simplifying the logic.  Remove some redundant initialisation.

Fixes for include file cleanups

This removes <linux/mm.h> from <linux/vmalloc.h>.

This then goes and fixes all of the files (x86 and PPC) which relied on
implicit includes which don't happen anymore.  This also takes
<linux/kdev_t.h> out of fs/mpage.c and puts it into include/linux/bio.h
where it belongs since <linux/bio.h> references 'kdev_t' directly.

A quick summary of the of the added includes:
arch/i386/kernel/microcode.c: needs extern for num_physpages, in linux/mm.h
include/linux/spinlock.h: local_irq* is defined in <asm/system.h> but
this was never directly included.

This moves the vmalloc wrappers from <linux/vmalloc.h> into mm/vmalloc.c.

Doing this will later allow us to remove <linux/mm.h> from <linux/vmalloc.h>,
along with some other #include fixups.

This patch removes the MSNFS defines.  These locks have a wider purpose
than emulating Microsoft NFS semantics.

This patch removes the annoying and confusing `wait' argument from
many places.  The only change in behaviour is that we now yield once
when unblocking other BSD-style flocks instead of once for each lock.

This slightly improves the semantics for userspace.  Before, when we
had two tasks waiting on a lock, the first one would receive the lock.
Now, the one with the highest priority receives the lock.
