->readstat() and ->writecmd() are always getting a userland pointer;
marked argument as such, killed "user" flag, killed dead code.

	inlined functions moved, a couple of heavy-weight ones (issue_scb()
and meg_cmd_done()) uninlined.

gcc doesn't understand that "asmlinkage" routines have the
argument stack owned by the assembly-language caller, and the
recent sparse cleanup made gcc think it owns enough stack
frame space to make a tailcall by overwriting "struct pt_regs"
that is set up by the low-level system call code.

Hide that problem again.

The real fix would be to tell gcc that the caller owns the
stack frame that it set up, but we don't have any such
interfaces, so for now the best we can do is to hide it.

After Andi's timestamp optimizations we don't have any timestamps on the

explicitly timestamp the packets before we log them.

Harald approved it some time ago, he's pretty busy so I'm sending it

[PATCH] s390: cpu hotplug bugs.

From: Ursula Braun-Krahl <braunu@de.ibm.com>
From: Martin Schwidefsky <schwidefsky@de.ibm.com>

iucv driver changes:
 - Fix iucv declare/retrieve buffer which the cpu hotplug patch has broken.
 - Make smp_call_function_on call func(info) in non-smp kernels.
 - Use a spinlock to get smp_get_cpu/smp_put_cpu race free.

s390 core changes:
 - Add signo between signal frame and the signal return instruction on the
   user stack for backtrace over signal handlers.
 - Add hfp floating point exceptions.
 - Use a single function for region, segment and page translation exceptions.
 - Discard SIGTRAP for single stepped instructions if the trapping instruction
   is repeated (normal memory faults) or if another signal is delivered anyway.

I believe reading the i_size from memory multiple times can generate fs
corruption.  The "offset" and the "end_index" were not coherent.  this is
writepages and it runs w/o the i_sem, so the i_size can change from under
us anytime.  If a parallel write happens while writepages run, the i_size
could advance from 4095 to 4100.  With the current 2.6 code that could
translate in end_index = 0 and offset = 4.  That's broken because end_index
and offset could be not coherent.  Either end_index=1 and offset =4, or
end_index = 0 and offset = 4095.  When they lose coherency the memset can
zeroout actual data.  The below patch fixes that (it's at least a
theoretical bug).

I don't really expect this tiny race to fix the bug in practice after the
more serious bugs we covered yesterday didn't fix it (more likely the
compiler will get involved into the equation soon ;).

This is also an optimization for 32bit archs that needs special locking to
read 64bit i_size coherenty.

This patch also arranges for mpage_writepages() to always zero out the file's
final page between i_size and the end of the file's final block.  This is a
best-effort correctness thing to deal with errant applications which write
into the mmapped page beyond the underlying file's EOF.

Fix a data loss bug in mpage_writepages(), triggerable under extreme memory
pressure on ext2, JFS, hfs and hfsplus:

The bug is the marking of the bh clean despite we could still run into the
"confused" path.  After that the confused path really becomes confused and it
writes nothing and fs corruption triggers silenty (the reugular writepage only
writes bh that are marked dirty, it never attempts to submit_bh anything
marked clean).  The mpage-writepage code must never mark the bh clean as far
as it wants to still fallback in the regular writepage which depends on the bh
to be dirty (i.e.  the "goto confused" path).  This could only triggers with
memory pressure (it also needs buffer_heads_over_limit == 0, and that is
frequent under mm pressure).

Thanks a lot to Chris for his fine debugging that localized the problem in the
writepage code.
