If there is an error creating a directory with securityfs_create_dir,
the error is propagated via ERR_PTR but the function comment claims that
NULL is returned.
This is a similar commit to 88e6c94cda322ff2b32f72bb8d96f9675cdad8aa
("fix long-broken securityfs_create_file comment") that did not fix
securityfs_create_dir comment at the same time.

Timur Tabi says:
====================
Add basic ACPI support to the Qualcomm Technologies EMAC driver
This patch series adds support to the EMAC driver for extracting addresses,
interrupts, and some _DSDs (properties) from ACPI. The first two patches
clean up the code, and the third patch adds ACPI-specific functionality.
The first patch fixes a bug with handling the platform_device for the
internal PHY. This phy is treated as a separate device in both DT and
ACPI, but since the platform is not released automatically when the
driver unloads, managed functions like devm_ioremap_resource cannot be
used.
The second patch replaces of_get_mac_address with its platform-independent
equivalent device_get_mac_address.
The third patch parses the ACPI tables to obtain the platform_device for
the primary EMAC node ("QCOM8070") and the internal phy node ("QCOM8071").

Add support for reading addresses, interrupts, and _DSD properties
from ACPI tables, just like with device tree. The HID for the
EMAC device itself is QCOM8070. The internal PHY is represented
by a child node with a HID of QCOM8071.
The EMAC also has some complex clock initialization requirements
that are not represented by this patch. This will be addressed
in a future patch.

The platform_device returned by of_find_device_by_node() is not
automatically released when the driver unprobes. Therefore,
managed calls like devm_ioremap_resource() should not be used.
Instead, we manually allocate the resources and then free them
on driver release.

Suppose you have a map array value that is something like this
struct foo {
unsigned iter;
int array[SOME_CONSTANT];
};
You can easily insert this into an array, but you cannot modify the contents of
foo->array[] after the fact. This is because we have no way to verify we won't
go off the end of the array at verification time. This patch provides a start
for this work. We accomplish this by keeping track of a minimum and maximum
value a register could be while we're checking the code. Then at the time we
try to do an access into a MAP_VALUE we verify that the maximum offset into that
region is a valid access into that memory region. So in practice, code such as
this
unsigned index = 0;
if (foo->iter >= SOME_CONSTANT)
foo->iter = index;
else
index = foo->iter++;
foo->array[index] = bar;
would be allowed, as we can verify that index will always be between 0 and
SOME_CONSTANT-1. If you wish to use signed values you'll have to have an extra
check to make sure the index isn't less than 0, or do something like index %=
SOME_CONSTANT.

__kernel_get_syscall_map() and __kernel_clock_getres() use cmpli to
check if the passed in pointer is non zero. cmpli maps to a 32 bit
compare on binutils, so we ignore the top 32 bits.
A simple test case can be created by passing in a bogus pointer with
the bottom 32 bits clear. Using a clk_id that is handled by the VDSO,
then one that is handled by the kernel shows the problem:
printf("%d\n", clock_getres(CLOCK_REALTIME, (void *)0x100000000));
printf("%d\n", clock_getres(CLOCK_BOOTTIME, (void *)0x100000000));
And we get:
0
-1
The bigger issue is if we pass a valid pointer with the bottom 32 bits
clear, in this case we will return success but won't write any data
to the pointer.
I stumbled across this issue because the LLVM integrated assembler
doesn't accept cmpli with 3 arguments. Fix this by converting them to
cmpldi.

When PCI Device pass-through is enabled via VFIO, KVM-PPC will
pin pages using get_user_pages_fast(). One of the downsides of
the pinning is that the page could be in CMA region. The CMA
region is used for other allocations like the hash page table.
Ideally we want the pinned pages to be from non CMA region.
This patch (currently only for KVM PPC with VFIO) forcefully
migrates the pages out (huge pages are omitted for the moment).
There are more efficient ways of doing this, but that might
be elaborate and might impact a larger audience beyond just
the kvm ppc implementation.
The magic is in new_iommu_non_cma_page() which allocates the
new page from a non CMA region.
I've tested the patches lightly at my end. The full solution
requires migration of THP pages in the CMA region. That work
will be done incrementally on top of this.

This supports PCI surprise hotplug. The design is highlighted as
below:
* The PCI slot's surprise hotplug capability is exposed through
device node property "ibm,slot-surprise-pluggable", meaning
PCI surprise hotplug will be disabled if skiboot doesn't support
it yet.
* The interrupt because of presence or link state change is raised
on surprise hotplug event. One event is allocated and queued to
the PCI slot for workqueue to pick it up and process in serialized
fashion. The code flow for surprise hotplug is same to that for
managed hotplug except: the affected PEs are put into frozen state
to avoid unexpected EEH error reporting in surprise hot remove path.

When issuing PHB reset, OPAL API opal_pci_poll() is called to drive
the state machine in OPAL forward. However, we needn't always call
the function under some circumstances like reset deassert.
This avoids calling opal_pci_poll() when OPAL_SUCCESS is returned
from opal_pci_reset(). Except the overhead introduced by additional
one unnecessary OPAL call, I didn't run into real issue because of
this.

The oom victim cannot terminate because it needs to take mmap_sem for
write while the lock is held by ksmd for read which loops in the page
allocator
ksm_do_scan
scan_get_next_rmap_item
down_read
get_next_rmap_item
alloc_rmap_item #ksmd will loop permanently.
There is no way forward because the oom victim cannot release any memory
in 4.1 based kernel. Since 4.6 we have the oom reaper which would solve
this problem because it would release the memory asynchronously.
Nevertheless we can relax alloc_rmap_item requirements and use
__GFP_NORETRY because the allocation failure is acceptable as ksm_do_scan
would just retry later after the lock got dropped.
Such a patch would be also easy to backport to older stable kernels which
do not have oom_reaper.
While we are at it add GFP_NOWARN so the admin doesn't have to be alarmed
by the allocation failure.

Resource allocation for VFs is done via the VF BARx registers in the PF's
SR-IOV Capability, and the BARs in the VFs themselves are read-only zeros
(see SR-IOV spec r1.1, secs 3.3.14 and 3.4.1.11).
Even though the actual VF BARs are read-only zeros, the VF dev->resource[]
structs describe the space allocated for the VF (this is a piece of the
space described by the VF BARx register in the PF's SR-IOV capability).
It's meaningless to request additional alignment for a VF: the VF BAR
alignment is completely determined by the alignment of the VF BARx in the
PF and the size of the VF BAR.
Ignore the user's alignment requests for VF devices.

Jouni reported that during (repeated) wext_pmf test runs (from the
wpa_supplicant hwsim test suite) the kernel crashes. The reason is
that after the key is set, the wext code still unnecessarily stores
it into the key cache. Despite smatch pointing out an overflow, I
failed to identify the possibility for this in the code and missed
it during development of the earlier patch series.
In order to fix this, simply check that we never store anything but
WEP keys into the cache, adding a comment as to why that's enough.
Also, since the cache is still allocated early even if it won't be
used in many cases, add a comment explaining why - otherwise we'd
have to roll back key settings to the driver in case of allocation
failures, which is far more difficult.

Users may request additional alignment of PCI resources, e.g., to align
BARs on page boundaries so they can be shared with guests via VFIO. This
of course may require reallocation if firmware has already assigned the
BARs with smaller alignments.
If the platform has requested PCI_PROBE_ONLY, we should never change any
PCI BARs, so we can't provide any additional alignment. Also, if a BAR is
marked as IORESOURCE_PCI_FIXED, e.g., for PCI Enhanced Allocation or if the
firmware depends on the current BAR value, we can't change the alignment.
In these cases, log a message and ignore the user's alignment requests.
