commit ecd75ad514d73efc1bbcc5f10a13566c3ace5f53 upstream.
For some reason, some early WD drives spin up and down drives
erratically when the link is put into slumber mode which can reduce
the life expectancy of the device significantly. Unfortunately, we
don't have full list of devices and given the nature of the issue it'd
be better to err on the side of false positives than the other way
around. Let's disable LPM on all WD devices which match one of the
known problematic model prefixes and are SATA-I.As horkage list doesn't support matching SATA capabilities, this is
implemented as two horkages - WD_BROKEN_LPM and NOLPM. The former is
set for the known prefixes and sets the latter if the matched device
is SATA-I.Note that this isn't optimal as this disables all LPM operations and
partial link power state reportedly works fine on these; however, the
way LPM is implemented in libata makes it difficult to precisely map
libata LPM setting to specific link power state. Well, these devices
are already fairly outdated. Let's just disable whole LPM for now.Signed-off-by: Tejun Heo

commit ed8f8318d2ef3e5f9e4ddf79349508c116b68d7f upstream.
According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB
register error issue", All USB register write operations must
use the ARM SWP instruction. So, we implement special hw_write
and hw_test_and_clear for imx28.Discussion for it at below:

commit 27c73ae759774e63313c1fbfeb17ba076cea64c5 upstream.
Commit 7cb2ef56e6a8 ("mm: fix aio performance regression for database
caused by THP") can cause dereference of a dangling pointer if
split_huge_page runs during PageHuge() if there are updates to the
tail_page->private field.Also it is repeating compound_head twice for hugetlbfs and it is running
compound_head+compound_trans_head for THP when a single one is needed in
both cases.The new code within the PageSlab() check doesn't need to verify that the
THP page size is never bigger than the smallest hugetlbfs page size, to
avoid memory corruption.A longstanding theoretical race condition was found while fixing the
above (see the change right after the skip_unlock label, that is
relevant for the compound_lock path too).By re-establishing the _mapcount tail refcounting for all compound
pages, this also fixes the below problem:echo 0 >/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

Add pinctrl data for ddr_vtt_toggle pin so that it is configured
for proper state during DeepSleep0. The pin should enter DS0 off mode
and hold the line low so VTT regulator is kept off while suspended.
It is also important for the PULLUP to be set on this pin so that
on removal of isolation, the VTT line is pulled high as a requirement
for bringing the DDR3 out of self-refresh.This toggling is dependent on the IO isolation controlled by the
wkup_m3. Without placing the IOs into isolation the DS0 states set for
the pin will not be latched into effect during suspend.Signed-off-by: Dave Gerlach

commit f92f455f67fef27929e6043499414605b0c94872 upstream.
{,set}page_address() are macros if WANT_PAGE_VIRTUAL. If
!WANT_PAGE_VIRTUAL, they're plain C functions.If someone calls them with a void *, this pointer is auto-converted to
struct page * if !WANT_PAGE_VIRTUAL, but causes a build failure on
architectures using WANT_PAGE_VIRTUAL (arc, m68k and sparc64):drivers/md/bcache/bset.c: In function `__btree_sort':

commit 2fac2b891f287691c27ee8d2eeecf39571b27fea upstream.
The body of i2c_parent_is_i2c_adapter() is currently guarded by
I2C_MUX. It should be CONFIG_I2C_MUX instead.Among potentially other problems, this resulted in i2c_lock_adapter()
only locking I2C mux child adapters, and not the parent adapter. In
turn, this could allow inter-mingling of mux child selection and I2C
transactions, which could result in I2C transactions being directed to
the wrong I2C bus, and possibly even switching between busses in the
middle of a transaction.One concrete issue caused by this bug was corrupted HDMI EDID reads
during boot on the NVIDIA Tegra Seaboard system, although this only
became apparent in recent linux-next, when the boot timing was changed
just enough to trigger the race condition.Fixes: 3923172b3d70 ("i2c: reduce parent checking to a NOOP in non-I2C_MUX case")

[ Upstream commit 7a7ffbabf99445704be01bff5d7e360da908cf8e ]
VM to VM GSO traffic is broken if it goes through VXLAN or GRE
tunnel and the physical NIC on the host supports hardware VXLAN/GRE
GSO offload (e.g. bnx2x and next-gen mlx4).Two issues -
(VXLAN) VM traffic has SKB_GSO_DODGY and SKB_GSO_UDP_TUNNEL with
SKB_GSO_TCP/UDP set depending on the inner protocol. GSO header
integrity check fails in udp4_ufo_fragment if inner protocol is
TCP. Also gso_segs is calculated incorrectly using skb->len that
includes tunnel header. Fix: robust check should only be applied
to the inner packet.(VXLAN & GRE) Once GSO header integrity check passes, NULL segs
is returned and the original skb is sent to hardware. However the
tunnel header is already pulled. Fix: tunnel header needs to be
restored so that hardware can perform GSO properly on the original
packet.Signed-off-by: Wei-Chun Chao

[ Upstream commit 2205369a314e12fcec4781cc73ac9c08fc2b47de ]
When the vlan code detects that the real device can do TX VLAN offloads
in hardware, it tries to arrange for the real device's header_ops to
be invoked directly.But it does so illegally, by simply hooking the real device's
header_ops up to the VLAN device.This doesn't work because we will end up invoking a set of header_ops
routines which expect a device type which matches the real device, but
will see a VLAN device instead.Fix this by providing a pass-thru set of header_ops which will arrange
to pass the proper real device instead.To facilitate this add a dev_rebuild_header(). There are
implementations which provide a ->cache and ->create but not a
->rebuild (f.e. PLIP). So we need a helper function just like
dev_hard_header() to avoid crashes.Use this helper in the one existing place where the
header_ops->rebuild was being invoked, the neighbour code.With lots of help from Florian Westphal.

ipgre_header_parse() needs to parse the tunnel's ip header and it
uses mac_header to locate the iphdr. This got broken when gre tunneling
was refactored as mac_header is no longer updated to point to iphdr.
Introduce skb_pop_mac_header() helper to do the mac_header assignment
and use it in ipgre_rcv() to fix msg_name parsing.Bug introduced in commit c54419321455 (GRE: Refactor GRE tunneling code.)

us to break out of it, triggering a hung task spew.Instead, allow set_peek_off to fail, this way userspace will not hang.

commit f244d8b623dae7a7bc695b0336f67729b95a9736 upstream.
The changes in the ACPI-based PCI hotplug (ACPIPHP) subsystem made
during the 3.12 development cycle uncovered a problem with VGA
switcheroo that on some systems, when the device-specific method
(ATPX in the radeon case, _DSM in the nouveau case) is used to turn
off the discrete graphics, the BIOS generates ACPI hotplug events for
that device and those events cause ACPIPHP to attempt to remove the
device from the system (they are events for a device that was present
previously and is not present any more, so that's what should be done
according to the spec). Then, the system stops functioning correctly.Since the hotplug events in question were simply silently ignored
previously, the least intrusive way to address that problem is to
make ACPIPHP ignore them again. For this purpose, introduce a new
ACPI device flag, no_hotplug, and modify ACPIPHP to ignore hotplug
events for PCI devices whose ACPI companions have that flag set.
Next, make the radeon and nouveau switcheroo detection code set the
no_hotplug flag for the discrete graphics' ACPI companion.Fixes: bbd34fcdd1b2 (ACPI / hotplug / PCI: Register all devices under the given bridge)

commit 8e321fefb0e60bae4e2a28d20fc4fa30758d27c6 upstream.
The arbitrary restriction on page counts offered by the core
migrate_page_move_mapping() code results in rather suspicious looking
fiddling with page reference counts in the aio_migratepage() operation.
To fix this, make migrate_page_move_mapping() take an extra_count parameter
that allows aio to tell the code about its own reference count on the page
being migrated.While cleaning up aio_migratepage(), make it validate that the old page
being passed in is actually what aio_migratepage() expects to prevent
misbehaviour in the case of races.Signed-off-by: Benjamin LaHaise

commit af2c1401e6f9177483be4fad876d0073669df9df upstream.
According to documentation on barriers, stores issued before a LOCK can
complete after the lock implying that it's possible tlb_flush_pending
can be visible after a page table update. As per revised documentation,
this patch adds a smp_mb__before_spinlock to guarantee the correct
ordering.Signed-off-by: Mel Gorman

commit 20841405940e7be0617612d521e206e4b6b325db upstream.
There are a few subtle races, between change_protection_range (used by
mprotect and change_prot_numa) on one side, and NUMA page migration and
compaction on the other side.The basic race is that there is a time window between when the PTE gets
made non-present (PROT_NONE or NUMA), and the TLB is flushed.During that time, a CPU may continue writing to the page.
This is fine most of the time, however compaction or the NUMA migration
code may come in, and migrate the page away.When that happens, the CPU may continue writing, through the cached
translation, to what is no longer the current memory location of the
process.This only affects x86, which has a somewhat optimistic pte_accessible.
All other architectures appear to be safe, and will either always flush,
or flush whenever there is a valid mapping, even with no permissions
(SPARC).The basic race looks like this:
CPU A CPU B CPU C
load TLB entry
make entry PTE/PMD_NUMA
fault on entry
read/write old page
start migrating page
change PTE/PMD to new page
read/write old page [*]
flush TLB
reload TLB from new entry
read/write new page
lose data[*] the old page may belong to a new user at this point!
The obvious fix is to flush remote TLB entries, by making sure that
pte_accessible aware of the fact that PROT_NONE and PROT_NUMA memory may
still be accessible if there is a TLB flush pending for the mm.This should fix both NUMA migration and compaction.

do_huge_pmd_numa_page() handles the case where there is parallel THP

information has already been disrupted. This patch adds an earlier

commit f78dea064c5f7de07de4912a6e5136dbc443d614 upstream.
Certain drives cannot handle queued TRIM commands properly, even
though support is indicated in the IDENTIFY DEVICE buffer. This patch
allows for disabling the commands for the affected drives and apply it
to the Micron/Crucial M500 SSDs which exhibit incorrect protocol
behavior when issued queued TRIM commands, which could lead to silent
data corruption.tj: Merged two unnecessarily split patches and made minor edits

commit 95cadace8f3959282e76ebf8b382bd0930807d2c upstream.
This patch allows FILEIO to update hw_max_sectors based on the current
max_bytes_per_io. This is required because vfs_[writev,readv]() can accept
a maximum of 2048 iovecs per call, so the enforced hw_max_sectors really
needs to be calculated based on block_size.This addresses a >= v3.5 bug where block_size=512 was rejecting > 1M
sized I/O requests, because FD_MAX_SECTORS was hardcoded to 2048 for
the block_size=4096 case.(v2: Use max_bytes_per_io instead of ->update_hw_max_sectors)

commit c97102ba96324da330078ad8619ba4dfe840dbe3 upstream.
Commit 1b3a5d02ee07 ("reboot: move arch/x86 reboot= handling to generic
kernel") moved reboot= handling to generic code. In the process it also
removed the code in native_machine_shutdown() which are moving reboot
process to reboot_cpu/cpu0.I guess that thought must have been that all reboot paths are calling
migrate_to_reboot_cpu(), so we don't need this special handling. But
kexec reboot path (kernel_kexec()) is not calling
migrate_to_reboot_cpu() so above change broke kexec. Now reboot can
happen on non-boot cpu and when INIT is sent in second kerneo to bring
up BP, it brings down the machine.So start calling migrate_to_reboot_cpu() in kexec reboot path to avoid
this problem.Bisected by WANG Chao.
