The DDR control initialization needs to know the SoC type, however
ath79_detect_sys_type() was called after ath79_ddr_ctrl_init().
Reverse the order to fix the DDR control initialization on ar71xx and
ar934x.

Advertising reordering window in ADDBA less than 64 can crash some APs,
an example is LinkSys WRT120N (with FW v1.0.07 build 002 Jun 18 2012).
On the other hand, a driver may need to limit Tx A-MPDU size for its own
reasons, like specific HW limitations.

It is not permitted to set task state before lock. usblp_wwait sets
the state to TASK_INTERRUPTIBLE and calls mutex_lock_interruptible.
Upon return from that function, the state will be TASK_RUNNING again.
This is clearly a bug and a warning is generated with LOCKDEP too:

A kernel thread executes __set_current_state(TASK_INTERRUPTIBLE),
__add_wait_queue, spin_unlock_irq and then tests kthread_should_stop().
It is possible that the processor reorders memory accesses so that
kthread_should_stop() is executed before __set_current_state(). If such
reordering happens, there is a possible race on thread termination:
CPU 0:
calls kthread_should_stop()
it tests KTHREAD_SHOULD_STOP bit, returns false
CPU 1:
calls kthread_stop(cc->write_thread)
sets the KTHREAD_SHOULD_STOP bit
calls wake_up_process on the kernel thread, that sets the thread
state to TASK_RUNNING
CPU 0:
sets __set_current_state(TASK_INTERRUPTIBLE)
spin_unlock_irq(&cc->write_thread_wait.lock)
schedule() - and the process is stuck and never terminates, because the
state is TASK_INTERRUPTIBLE and wake_up_process on CPU 1 already
terminated
Fix this race condition by using a new flag DM_CRYPT_EXIT_THREAD to
signal that the kernel thread should exit. The flag is set and tested
while holding cc->write_thread_wait.lock, so there is no possibility of
racy access to the flag.
Also, remove the unnecessary set_task_state(current, TASK_RUNNING)
following the schedule() call. When the process was woken up, its state
was already set to TASK_RUNNING. Other kernel code also doesn't set the
state to TASK_RUNNING following schedule() (for example,
do_wait_for_common in completion.c doesn't do it).

As previously reported, some userspace applications depend on bogomips

aarch64 than arm, it does break libvirt.
This patch reverts commit 326b16db9f69 ("arm64: delay: don't bother
reporting bogomips in /proc/cpuinfo"), but with some tweak due to
context change and without the pr_info().

On some host errors storvsc module tries to remove sdev by scheduling a job
which does the following:
sdev = scsi_device_lookup(wrk->host, 0, 0, wrk->lun);
if (sdev) {
scsi_remove_device(sdev);
scsi_device_put(sdev);
}
While this code seems correct the following crash is observed:
general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC
RIP: 0010:[<ffffffff81169979>] [<ffffffff81169979>] bdi_destroy+0x39/0x220
...
[<ffffffff814aecdc>] ? _raw_spin_unlock_irq+0x2c/0x40

[<ffffffff81080791>] process_one_work+0x1b1/0x530
...
The problem comes with the fact that many such jobs (for the same device)
are being scheduled simultaneously. While scsi_remove_device() uses
shost->scan_mutex and scsi_device_lookup() will fail for a device in
SDEV_DEL state there is no protection against someone who did
scsi_device_lookup() before we actually entered __scsi_remove_device(). So
the whole scenario looks like that: two callers do simultaneous (or
preemption happens) calls to scsi_device_lookup() ant these calls succeed
for both of them, after that they try doing scsi_remove_device().
shost->scan_mutex only serializes their calls to __scsi_remove_device()
and we end up doing the cleanup path twice.

If cdev_add() returns an error, the code calls
cdev_del() passing the STm->cdevs[rew] pointer as parameter;
the problem is that the pointer has not been initialized yet.
This patch fixes the problem by moving the STm->cdevs[rew] pointer
initialization before the call to cdev_add().
It also sets STm->devs[rew] and STm->cdevs[rew] to NULL in
case of failure.

Some host adapters (e.g. Hyper-V storvsc) are known for not respecting
the SPC-2/3/4 requirement for 'INQUIRY data (see table ...) shall
contain at least 36 bytes'. As a result we get tons on 'scsi 0:7:1:1:
scsi scan: INQUIRY result too short (5), using 36' messages on
console. This can be problematic for slow consoles. Introduce
short_inquiry flag in struct Scsi_Host to print the message once per
host.

KVM: s390: Fixes for 4.4
1. disallow changing the SIMD mode when CPUs have been created.
it allowed userspace to corrupt kernel memory
2. Fix vCPU lookup. Until now the vCPU number equals the vCPU id. Some
kernel code places relied on that. This might
a: cause guest failures
b: allow userspace to corrupt kernel memory
3. Fencing of the PFMF instruction should use the guest facilities
and not the host facilities.

For SKL, only the HDMI codec is in the display power well while the
HD-A controller isn't. So the codec flag 'link_power_control' is
set to request/release the display power via bus link_power ops.
For BXT, the power well design is the same as SKL, so the patch
should be applied to BXT too.

The scpi_clock driver can be built-in when CONFIG_COMPILE_TEST
is set even when ARM_SCPI_PROTOCOL is a loadable module, and
that results in a link error:
drivers/built-in.o: In function `scpi_clocks_probe':
(.text+0x14453c): undefined reference to `get_scpi_ops'
Using #if IS_REACHABLE() around the get_scpi_ops() declaration
makes it build successfully in this case for compile-testing,
but the effect is the same as when ARM_SCPI_PROTOCOL is
disabled, as the code will not be used.

The newly added zx power domain code causes build errors in
some configurations:
warning: (PM_RMOBILE && SOC_ZX296702) selects PM_GENERIC_DOMAINS which has unmet direct dependencies (PM)
warning: (ARCH_EXYNOS) selects EXYNOS_THERMAL which has unmet direct dependencies (THERMAL && (ARCH_EXYNOS || COMPILE_TEST) && THERMAL_OF)
power/domain.c: In function 'genpd_queue_power_off_work':
power/domain.c:192:13: error: 'pm_wq' undeclared (first use in this function)
queue_work(pm_wq, &genpd->power_off_work);
^
power/domain.c:192:13: note: each undeclared identifier is reported only once for each function it appears in
This ensures we don't try to enable it when CONFIG_PM is
disabled, mirroring what we do on most other platforms.

This was totally lost when I originally created the atomic helpers.
We probably should also check possible_clones in the helpers, but
since the legacy ones didn't do that this is for a separate patch.
