When performing partition migrations all present CPUs must be online
as all present CPUs must make the H_JOIN call as part of the migration
process. Once all present CPUs make the H_JOIN call, one CPU is returned
to make the rtas call to perform the migration to the destination system.
During testing of migration and changing the SMT state we have found
instances where CPUs are offlined, as part of the SMT state change,
before they make the H_JOIN call. This results in a hung system where
every CPU is either in H_JOIN or offline.
To prevent this this patch disables CPU hotplug during the migration
process.

Calling napi_schedule() from process context does not ensure that the
NET_RX softirq is run in a timely fashion. So trigger it manually.
This is no big issue with current code. A call to ndo_open() is usually
followed by a ndo_set_rx_mode() call, and for qeth this contains a
spin_unlock_bh(). Except for OSN, where qeth_l2_set_rx_mode() bails out
early.
Nevertheless it's best to not depend on this behaviour, and just fix
the issue at its source like all other drivers do. For instance see
commit 83a0c6e58901 ("i40e: Invoke softirqs after napi_reschedule").

Call Frame Information is used by gdb for back-traces and inserting
breakpoints on function return for the "finish" command. This failed
when inside __kernel_clock_gettime. More concerning than difficulty
debugging is that CFI is also used by stack frame unwinding code to
implement exceptions. If you have an app that needs to handle
asynchronous exceptions for some reason, and you are unlucky enough to
get one inside the VDSO time functions, your app will crash.
What's wrong: There is control flow in __kernel_clock_gettime that
reaches label 99 without saving lr in r12. CFI info however is
interpreted by the unwinder without reference to control flow: It's a
simple matter of "Execute all the CFI opcodes up to the current
address". That means the unwinder thinks r12 contains the return
address at label 99. Disabuse it of that notion by resetting CFI for
the return address at label 99.
Note that the ".cfi_restore lr" could have gone anywhere from the
"mtlr r12" a few instructions earlier to the instruction at label 99.
I put the CFI as late as possible, because in general that's best
practice (and if possible grouped with other CFI in order to reduce
the number of CFI opcodes executed when unwinding). Using r12 as the
return address is perfectly fine after the "mtlr r12" since r12 on
that code path still contains the return address.
__get_datapage also has a CFI error. That function temporarily saves
lr in r0, and reflects that fact with ".cfi_register lr,r0". A later
use of r0 means the CFI at that point isn't correct, as r0 no longer
contains the return address. Fix that too.

Vendor defined U-Boot has changed the partition scheme a while ago:
* kernel partition 6MB
* file system partition uses the remainder up to end of the NAND
* increased size of the environment partition (to get an OneNAND compatible base address)
* shrink the U-Boot partition
Let's be compatible (e.g. Debian kernel built from upstream).

This is done in order not to trig the below warning in
ieee80211_rx_napi:
WARN_ON_ONCE(softirq_count() == 0);
ieee80211_rx_napi requires that softirq's are disabled during
execution.
The High latency bus drivers (SDIO and USB) sometimes call the wmi
ep_rx_complete callback from non softirq context, resulting in a trigger
of the above warning.
Calling ieee80211_rx_ni with softirq's already disabled (e.g., from
softirq context) should be safe as the local_bh_disable and
local_bh_enable functions (called from ieee80211_rx_ni) are fully
reentrant.

In the case where lo_vag <= SGTL5000_LINE_OUT_GND_BASE, lo_vag
is set to zero and later vol_quot is computed by dividing by
lo_vag causing a division by zero error. Fix this by avoiding
a zero division and set vol_quot to zero in this specific case
so that the lowest setting for i is correctly set.
