ASoC: Fixes for v3.16
A bigger batch of changes than I would like as I didn't send any for a
few weeks without noticing how many had built up. They are almost all
driver specific though, larger changes are:
- Fixes to the newly added Baytrail/MAX98090 which look like some QA
was missed on the microphone detection.
- Deletion of some erroniously listed audio formats for Haswell.
- Fix debugfs creation in the core so that we don't try to generate
multiple directories with the same name, relatively large textually
but simple to inspect by eye and test.
- A couple of bugfixes for the rcar driver one of which which involves
a bit of code motion to move initailisation of some hardware out of
common paths into device specific ones.
- Ensure both channels are powered up for mono outputs on Arizona
devices, involving some simple data tables listing the outputs and a
loop over them.
- A couple of fixes to save and restore information on suspended and
idle Samsung I2S controllers.

dm bufio: fully initialize shrinker
1d3d4437eae1 ("vmscan: per-node deferred work") added a flags field to
struct shrinker assuming that all shrinkers were zero filled. The dm
bufio shrinker is not zero filled, which leaves arbitrary kmalloc() data
in flags. So far the only defined flags bit is SHRINKER_NUMA_AWARE.
But there are proposed patches which add other bits to shrinker.flags
(e.g. memcg awareness).
Rather than simply initializing the shrinker, this patch uses kzalloc()
when allocating the dm_bufio_client to ensure that the embedded shrinker
and any other similar structures are zeroed.
This fixes theoretical over aggressive shrinking of dm bufio objects.
If the uninitialized dm_bufio_client.shrinker.flags contains
SHRINKER_NUMA_AWARE then shrink_slab() would call the dm shrinker for
each numa node rather than just once. This has been broken since 3.12.

crypto: af_alg - properly label AF_ALG socket
Th AF_ALG socket was missing a security label (e.g. SELinux)

kexec: export free_huge_page to VMCOREINFO
PG_head_mask was added into VMCOREINFO to filter huge pages in
b3acc56bfe1
("kexec: save PG_head_mask in VMCOREINFO"), but makedumpfile still need
another symbol to filter *hugetlbfs* pages.
If a user hope to filter user pages, makedumpfile tries to exclude them by
checking the condition whether the page is anonymous, but hugetlbfs pages
aren't anonymous while they also be user pages.
We know it's possible to detect them in the same way as PageHuge(),
so we need the start address of free_huge_page():
int PageHuge(struct page *page)
{
if (!PageCompound(page))
return 0;
page = compound_head(page);
return get_compound_page_dtor(page) == free_huge_page;
}
For that reason, this patch changes free_huge_page() into public
to export it to VMCOREINFO.

assuming it is protected by the hierarchical OOM-lock.
Although this is true for the notification part the protection doesn't
cover unregistration of event which can happen in parallel now so
mem_cgroup_oom_notify can see already unlinked and/or freed

Fix this by using memcg_oom_lock also in mem_cgroup_oom_notify.

mm, thp: do not allow thp faults to avoid cpuset restrictions
The page allocator relies on __GFP_WAIT to determine if ALLOC_CPUSET
should be set in allocflags. ALLOC_CPUSET controls if a page allocation
should be restricted only to the set of allowed cpuset mems.
Transparent hugepages clears __GFP_WAIT when defrag is disabled to prevent
the fault path from using memory compaction or direct reclaim. Thus, it
is unfairly able to allocate outside of its cpuset mems restriction as a
side-effect.
This patch ensures that ALLOC_CPUSET is only cleared when the gfp mask is
truly GFP_ATOMIC by verifying it is also not a thp allocation.

ARM: nomadik: fix up double inversion in DT
The GPIO pin connected to card detect was inverted twice: once by
the argument to the GPIO line itself where it was magically marked
as active low by the flag GPIO_ACTIVE_LOW (0x01) in the third cell,
and also marked active low AGAIN by explicitly stating
"cd-inverted" (a deprecated method).
After commit
78f87df2b4f8760954d7d80603d0cfcbd4759683
"mmc: mmci: Use the common mmc DT parser" this results in the
line being inverted twice so it was effectively uninverted, while
the old code would not have this effect, instead disregarding the
flag on the GPIO line altogether, which is a bug. I admit the
semantics may be unclear but inverting twice is as good a
definition as any on how this should work.
So fix up the buggy device tree. Use proper #includes so the DTS
is clear and readable.

x86/xen: safely map and unmap grant frames when in atomic context
arch_gnttab_map_frames() and arch_gnttab_unmap_frames() are called in
atomic context but were calling alloc_vm_area() which might sleep.
Also, if a driver attempts to allocate a grant ref from an interrupt
and the table needs expanding, then the CPU may already by in lazy MMU
mode and apply_to_page_range() will BUG when it tries to re-enable
lazy MMU mode.
These two functions are only used in PV guests.
Introduce arch_gnttab_init() to allocates the virtual address space in
advance.
Avoid the use of apply_to_page_range() by using saving and using the
array of PTE addresses from the alloc_vm_area() call (which ensures
that the required page tables are pre-allocated).

kvm: arm64: vgic: fix hyp panic with 64k pages on juno platform
If the physical address of GICV isn't page-aligned, then we end up
creating a stage-2 mapping of the page containing it, which causes us to
map neighbouring memory locations directly into the guest.
As an example, consider a platform with GICV at physical 0x2c02f000
running a 64k-page host kernel. If qemu maps this into the guest at
0x80010000, then guest physical addresses 0x80010000 - 0x8001efff will
map host physical region 0x2c020000 - 0x2c02efff. Accesses to these
physical regions may cause UNPREDICTABLE behaviour, for example, on the
Juno platform this will cause an SError exception to EL3, which brings
down the entire physical CPU resulting in RCU stalls / HYP panics / host
crashing / wasted weeks of debugging.
SBSA recommends that systems alias the 4k GICV across the bounding 64k
region, in which case GICV physical could be described as 0x2c020000 in
the above scenario.
This patch fixes the problem by failing the vgic probe if the physical
base address or the size of GICV aren't page-aligned. Note that this
generated a warning in dmesg about freeing enabled IRQs, so I had to
move the IRQ enabling later in the probe.

arm: Add devicetree fixup machine function
Commit
1c2f87c22566cd057bc8cde10c37ae9da1a1bb76
(ARM: 8025/1: Get rid of meminfo) dropped the upper bound on
the number of memory banks that can be added as there was no
technical need in the kernel. It turns out though, some bootloaders
(specifically the arndale-octa exynos boards) may pass invalid memory
information and rely on the kernel to not parse this data. This is a
bug in the bootloader but we still need to work around this.
Work around this by introducing a dt_fixup function. This function
gets called before the flattened devicetree is scanned for memory
and the like. In this fixup function for exynos, limit the maximum
number of memory regions in the devicetree.

ACPI / PNP: Fix acpi_pnp_match()
The acpi_pnp_match() function is used for finding the ACPI device
object that should be associated with the given PNP device.
Unfortunately, the check used by that function is not strict enough
and may cause success to be returned for a wrong ACPI device object.
To fix that, use the observation that the pointer to the ACPI
device object in question is already stored in the data field
in struct pnp_dev, so acpi_pnp_match() can simply use that
field to do its job.

net: phy: re-apply PHY fixups during phy_register_device
Commit
87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()")
moved the call to phy_scan_fixups() in phy_init_hw() after a software
reset is performed.
By the time phy_init_hw() is called in phy_device_register(), no driver
has been bound to this PHY yet, so all the checks in phy_init_hw()
against the PHY driver and the PHY driver's config_init function will
return 0. We will therefore never call phy_scan_fixups() as we should.
Fix this by calling phy_scan_fixups() and check for its return value to
restore the intended functionality.
This broke PHY drivers which do register an early PHY fixup callback to
intercept the PHY probing and do things like changing the 32-bits unique
PHY identifier when a pseudo-PHY address has been used, as well as
board-specific PHY fixups that need to be applied during driver probe
time.

This reports means that we've come to netlink_sendmsg() with msg->msg_name == NULL and msg->msg_namelen > 0.
After this report there was no usual "Unable to handle kernel NULL pointer dereference"
and this gave me a clue that address 0 is mapped and contains valid socket address structure in it.
This bug was introduced in
f3d3342602f8bcbf37d7c46641cb9bca7618eb1c
(net: rework recvmsg handler msg_name and msg_namelen logic).
Commit message states that:
"Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
affect sendto as it would bail out earlier while trying to copy-in the
address."
But in fact this affects sendto when address 0 is mapped and contains
socket address structure in it. In such case copy-in address will succeed,
verify_iovec() function will successfully exit with msg->msg_namelen > 0
and msg->msg_name == NULL.
This patch fixes it by setting msg_namelen to 0 if msg_name == NULL.
