For some unknown reason the mcck_interruption_code field is defined
as array of two 32 bit values. Given that this actually is a 64 bit
field according to the architecture, change the type to u64.

The cpu flags and pt_regs flags fields are each 64 bits in size. A flag can
be set with helper functions like set_cpu_flags().
These functions create a mask using "1U << flag". This doesn't work if flag
is larger than 31, since 1U << 32 == 0.
So fix this in case we ever will have such flag numbers.

When using systemtap it was observed that our udelay implementation is
rather suboptimal if being called from a kprobe handler installed by
systemtap.
The problem observed when a kprobe was installed on lock_acquired().
When the probe was hit the kprobe handler did call udelay, which set
up an (internal) timer and reenabled interrupts (only the clock comparator
interrupt) and waited for the interrupt.
This is an optimization to avoid that the cpu is busy looping while waiting
that enough time passes. The problem is that the interrupt handler still
does call irq_enter()/irq_exit() which then again can lead to a deadlock,
since some accounting functions may take locks as well.
If one of these locks is the same, which caused lock_acquired() to be
called, we have a nice deadlock.
This patch reworks the udelay code for the interrupts disabled case to
immediately leave the low level interrupt handler when the clock
comparator interrupt happens. That way no C code is being called and the
deadlock cannot happen anymore.

The program parameter can be used to mark hardware samples with
some token. Previously, it was used to mark guest samples only.
Improve the program parameter doubleword by combining two parts,
the leftmost LPP part and the rightmost PID part. Set the PID
part for processes by using the task PID.
To distinguish host and guest samples for the kernel (PID part
is zero), the guest must always set the program paramater to a
non-zero value. Use the leftmost bit in the LPP part of the
program parameter to be able to detect guest kernel samples.

The sclp console and tty code currently uses several message text
objects in a single message event to print several lines with one
SCCB. This causes the output of these lines to be fused into a
block which is noticeable when selecting text in the operating system
message panel.
Instead use several message events with a single message text object
each to print every line on its own. This changes the SCCB layout

Various functions in entry.S perform test-under-mask instructions
to test for particular bits in memory. Because test-under-mask uses
a mask value of one byte, the mask value and the offset into the
memory must be calculated manually. This easily introduces errors
and is hard to review and read.
Introduce the TSTMSK assembler macro to specify a mask constant and
let the macro calculate the offset and the byte mask to generate a
test-under-mask instruction. The benefit is that existing symbolic
constants can now be used for tests. Also the macro checks for
zero mask values and mask values that consist of multiple bytes.

If the kernel detects that the s390 hardware supports the vector
facility, it is enabled by default at an early stage. To force
it off, use the novx kernel parameter. Note that there is a small
time window, where the vector facility is enabled before it is
forced to be off.
With enabling the vector facility by default, the FPU save and
restore functions can be improved. They do not longer require
to manage expensive control register updates to enable or disable
the vector enablement control for particular processes.

The principles of operation states reads are in order, writes are in
order, writes can be reordered after reads, but no reads can be
reordered after writes.
The atomic and bitops variantes for z196 use the interlocked-access

The generic implementation for test_and_set_bit_lock in include/asm-generic
uses the standard test_and_set_bit operation. This is done with either a
'csg' or a 'loag' instruction. For both version the cache line is fetched
exclusively, even if the bit is already set. The result is an increase in
cache traffic, for a contented lock this is a bad idea.

Devices with active channel measurement are included in a list. When a
device is removed without deactivating channel measurement first the
list_head is freed but still used. Fix this by making sure that
channel measurement is deactivated during device deregistration.
For devices that we deregister because they are no longer accessible
deactivating channel measurement will fail. In this case we can report
success because the FW will no longer access the measurement block.
In addition to these steps keep an extra device reference while
channel measurement is active.

The principles of operation says:
The storage-operand fetch references of one instruction
occur after those of all preceding instructions and
before those of subsequent instructions, as observed
by other CPUs and by channel programs.
[...]
The CPU may fetch the operands of instructions before the
instructions are executed.
[...]
The CPU may delay placing results in storage.
[...]
the results of one instruction are placed in storage after
the results of all preceding instructions have been placed
in storage and before any results of the succeeding
instructions are stored, as observed by other CPUs and by
the channel subsystem.
which boils down to:
- reads are in order
- writes are in order
- reads can happen earlier
- writes can happen later
By definition (see memory-barrier.txt) read barriers orders
reads vs reads and write barriers orders writes agains writes.
but neither of these orders reads vs. writes.
That means we can implement smp_wmb,smp_rmb,wmb and rmb as
simple compiler barriers. To avoid reviewing all driver code
for correct barrier usage we keep dma_[rw]mb as serialization
for now.

We were able to reduce the CPU overhead of big paging scenarios
when announcing our paging disks as non-rotational.
Almost all dasd devices are implemented in storage servers with
cache, raid, striping and lots of magic. There is no point in
optimizing the disk schedulers and swap code for a single platter
moving arm rotational disks. Given the complexity of the setup
and the fact that this change is mostly to disable the additional
overhead in swap code, lets keep the other functionality unchanged
and do not disable the this device as entropy source - unlike other
non-rotational devices.

Now that the NFS server advertises a maximum payload size of 1MB
for RPC/RDMA again, it crashes in svc_process_common() when NFS
client sends a 1MB NFS WRITE on an NFS/RDMA mount.
The server has set up a 259 element array of struct page pointers
in rq_pages[] for each incoming request. The last element of the
array is NULL.
When an incoming request has been completely received,
rdma_read_complete() attempts to set the starting page of the
incoming page vector:
rqstp->rq_arg.pages = &rqstp->rq_pages[head->hdr_count];
and the page to use for the reply:
rqstp->rq_respages = &rqstp->rq_arg.pages[page_no];
But the value of page_no has already accounted for head->hdr_count.
Thus rq_respages now points past the end of the incoming pages.
For NFS WRITE operations smaller than the maximum, this is harmless.
But when the NFS WRITE operation is as large as the server's max
payload size, rq_respages now points at the last entry in rq_pages,
which is NULL.
Fixes: cc9a903d915c ('svcrdma: Change maximum server payload . . .')
