Duh... Even a simple one-liner test can be wrong. The really sad bit
is that I made the same mistake 3 weeks ago, fixed it, and then lost
track of the fix...

To recap fix to fix: A valid end of directory marker has to read
(entry[0]==0 && entry[1]!=0). Here is final correct (I hope) patch.

I think I have found it and it only hits on a 64 bit machine.

If the timeout is big enough we still need to initialise timer->entry.
Otherwise bad things happen we we hit del_timer.

Replace IMMEDIATE_BH bottom half by tasklets in helper functions for
console control characters. Fix a race condition and make it look nicer.

Don't create /proc/interrupts on s390.

Remove call to s390_init_machine_check in init/main.c, the new boot code
on s390 calls it via arch_initcall.

Rework boot sequence on s390:

Traditionally, device detection os s390 is done completely
at a _very_ early stage during bootup (from init_irq(),
i.e. before memory management or the console are there).

This has always been a bad idea, but now it broke even more
since the linux driver model requires devices detection
to take place after the core_initcalls are done.

We now do only a small amount of scanning (probably
less in the future) at the early stage, the bulk of it
is done from a proper subsys_initcall(). This requires
some changes in related areas:

- the machine check handler initialization is split in
  two halves, since we want to catch major machine malfunctions
  as early as possible, but device machine checks can only
  be caught after the channel subsystem is up.

- some functions that are called from the css initialization
  made some assumptions of when to use kmalloc or bootmem_alloc,
  which were broken anyway. We fix this here and hopefully
  can get rid of bootmem_alloc for the css completely in the future.

- the debug logging feature for s390 was not used for functions
  in the initialization before, since it requires the memory
  management to be working. Now that we can be sure that it
  works, some special cases can be removed.

Now that these changes are done, a partial implementation of the
device model for the channel subsystem is possible, but at this
point, none of the device drivers make use of that yet.

Check if defined chpids are available. Some code simplification.

Cleanup s390_process_IRQ a little, the ending_status argument is never
really used.

Remove bogus sanity check from {en,dis}able_sync_isc() and really disable all
interrupt sub classes except isc 7 in wait_cons_dev.

Add 'signal quiesque' feature to s390 hardware console. A signal quiesce
is sent from VM or the service element every time the system should shut
down. We receive the quiesce signal and call ctrl_alt_del(). Finally the
mainframes have ctrl-alt-del as well :-)

Rewrite s390 ptrace code in a more readable and less buggy way. As a part of
this, all psw related definitions are moved into ptrace.h from a number of
different locations.

Cleanup load/store of fpu register on s390.

Remove bogus sanity checks and code cleanup.

Make timer interrupt independent from boot cpu and do several ticks in one
go if a virtual cpu didn't get an interrupt for a period of time > HZ.

Use diag 0x44 on s390x for spinlocks.

Inline csum_partial for s390, the only reason it was out-of-line previously
is that some older compilers could not get the inline version right.

Add support for kernel preemption on s390/s390x.

Use a preprocessed linker script for building vmlinux on s390/s390x.

Fix bug in 31 bit emulation of sys_msgsnd and rename sys32_pread/sys32_pwrite
to sys32_pread64/sys32_pwrite64.

Fix broken bitops for unaligned atomic operations on s390.

Replace IMMEDIATE_BH bottom half by tasklets in 3215, ctc and iucv driver.

Remove reference to xpram_release. Correct calls to bi_end_io and bio_io_error.

Remove some configuration options that don't really make sense.

Correct includes in ibm.c to make it compile.

New system calls: security, async. i/o and sys_exit_group. Add 31 bit emulation
function for sys_futex.

s390 minimal device drivers changes for 2.5.39.

s390 include file changes for 2.5.39.

s390 arch file changes for 2.5.39.
