Merge our fixes branch into next, this brings in a number of commits
that fix bugs we don't want to hit in next, in particular the fix for
CVE-2019-12817.
Pull powerpc fixes from Michael Ellerman:
"This is a frustratingly large batch at rc5. Some of these were sent
earlier but were missed by me due to being distracted by other things,
and some took a while to track down due to needing manual bisection on
old hardware. But still we clearly need to improve our testing of KVM,
and of 32-bit, so that we catch these earlier.
Summary: seven fixes, all for bugs introduced this cycle.
- The commit to add KASAN support broke booting on 32-bit SMP
machines, due to a refactoring that moved some setup out of the
secondary CPU path.
- A fix for another 32-bit SMP bug introduced by the fast syscall
entry implementation for 32-bit BOOKE. And a build fix for the same
commit.
- Our change to allow the DAWR to be force enabled on Power9
introduced a bug in KVM, where we clobber r3 leading to a host
crash.
- The same commit also exposed a previously unreachable bug in the
nested KVM handling of DAWR, which could lead to an oops in a
nested host.
- One of the DMA reworks broke the b43legacy WiFi driver on some
people's powermacs, fix it by enabling a 30-bit ZONE_DMA on 32-bit.
- A fix for TLB flushing in KVM introduced a new bug, as it neglected
to also flush the ERAT, this could lead to memory corruption in the
guest.

A couple of bugs in queue_hotplug_event():
1. Unchecked kmalloc result which could lead to an oops.
2. Use of GFP_KERNEL allocations in interrupt context (this code's
only caller is ras_hotplug_interrupt()).
Use kmemdup to avoid open-coding the allocation+copy and check for
failure; use GFP_ATOMIC for both allocations.
Ultimately it probably would be better to avoid or reduce allocations
in this path if possible.

It's common for the platform to replace the cache device nodes after a

never drops its references to the source system's cache nodes, causing
it to wind up in an inconsistent state resulting in warnings and oopses

While developing KASAN for 64-bit book3s, I hit the following stack

It occurs because the hypercall to put characters onto the terminal

hvc_put_chars() would unconditionally copy 16 bytes from the argument

In commit:
4b53a3412d ("sched/core: Remove the tsk_nr_cpus_allowed() wrapper")
the tsk_nr_cpus_allowed() wrapper was removed. There was not
much difference in !RT but in RT we used this to implement
migrate_disable(). Within a migrate_disable() section the CPU mask is
restricted to single CPU while the "normal" CPU mask remains untouched.
As an alternative implementation Ingo suggested to use:
struct task_struct {
const cpumask_t *cpus_ptr;
cpumask_t cpus_mask;
};
with
t->cpus_ptr = &t->cpus_mask;
In -RT we then can switch the cpus_ptr to:
t->cpus_ptr = &cpumask_of(task_cpu(p));
in a migration disabled region. The rules are simple:
- Code that 'uses' ->cpus_allowed would use the pointer.
- Code that 'modifies' ->cpus_allowed would use the direct mask.

powerpc/powernv: Return for invalid IMC domain
Since 902bdc5745, get_pci_dev() calls pci_get_domain_bus_and_slot(). This
has the effect of incrementing the reference count of the PCI device, as
explained in drivers/pci/search.c:
* Given a PCI domain, bus, and slot/function number, the desired PCI
* device is located in the list of PCI devices. If the device is
* found, its reference count is increased and this function returns a
* pointer to its data structure. The caller must decrement the
* reference count by calling pci_dev_put(). If no device is found,
* %NULL is returned.
Nothing was done to call pci_dev_put() and the reference count of GPU and
NPU PCI devices rockets up.
A natural way to fix this would be to teach the callers about the change,
so that they call pci_dev_put() when done with the pointer. This turns
out to be quite intrusive, as it affects many paths in npu-dma.c,
pci-ioda.c and vfio_pci_nvlink2.c. Also, the issue appeared in 4.16 and
some affected code got moved around since then: it would be problematic
to backport the fix to stable releases.
All that code never cared for reference counting anyway. Call pci_dev_put()
from get_pci_dev() to revert to the previous behavior.

All of the remaining callers pass current into force_sig so
remove the task parameter to make this obvious and to make
misuse more difficult in the future.
This also makes it clear force_sig passes current into force_sig_info.

Currently init_imc_pmu() can fail either because we try to register an
IMC unit with an invalid domain (i.e an IMC node not supported by the
kernel) or something went wrong while registering a valid IMC unit. In
both the cases kernel provides a 'Register failed' error message.
For example when trace-imc node is not supported by the kernel, but
skiboot advertises a trace-imc node we print:
IMC Unknown Device type
IMC PMU (null) Register failed
To avoid confusion just print the unknown device type message, before
attempting PMU registration, so the second message isn't printed.
Fixes: 8f95faaac5 ("powerpc/powernv: Detect and create IMC device")
