On Ideapad laptops, ACPI event 1 is currently not handled. Many models
log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while
running on battery power. Some convertible laptops receive this event
when switching in and out of tablet mode.
This adds and additional case for event 1 in ideapad_acpi_notify to call
ideapad_input_report(priv, vpc_bit), so that the event is reported to
userspace and we avoid unnecessary logging.

Pull USB fixes from Greg KH:
"Here are a few small USB fixes for 4.10-rc5.
Most of these are gadget/dwc2 fixes for reported issues, all of these
have been in linux-next for a while. The last one is a single xhci
WARN_ON removal to handle an issue that the dwc3 driver is hitting in
the 4.10-rc tree. The warning is harmless and needs to be removed, and
a "real" fix that is more complex will show up in 4.11-rc1 for this
device.
That last patch hasn't been in linux-next yet due to the weekend
timing, but it's a "simple" WARN_ON() removal so what could go wrong?

Pull libnvdimm fixes from Dan Williams:
"Two fixes:
- a regression fix for the multiple-pmem-namespace-per-region support
added in 4.9. Even if an existing environment is not using that
feature the act of creating and a destroying a single namespace
with the ndctl utility will lead to the proliferation of extra
unwanted namespace devices.
- a fix for the error code returned from the pmem driver when the
memcpy_mcsafe() routine returns -EFAULT. Btrfs seems to be the only
block I/O consumer that tries to parse the meaning of the error
code when it is non-zero.
Neither of these fixes are critical, the namespace leak is awkward in
that it can cause device naming to change and complicates debugging
namespace initialization issues. The error code fix is included out of
caution for what other consumers might be expecting -EIO for block I/O
errors"

During an OOM scenario, request slots could not be created as skb
allocation fails. So the netback cannot pass in packets and netfront
wrongly assumes that there is no more work to be done and it disables
polling. This causes Rx to stall.
The issue is with the retry logic which schedules the timer if the
created slots are less than NET_RX_SLOTS_MIN. The count of new request
slots to be pushed are calculated as a difference between new req_prod
and rsp_cons which could be more than the actual slots, if there are
unconsumed responses.
The fix is to calculate the count of newly created slots as the
difference between new req_prod and old req_prod.

struct qed_ll2_info is rather large, so putting it on the stack
can cause an overflow, as this warning tries to tell us:
drivers/net/ethernet/qlogic/qed/qed_ll2.c: In function 'qed_ll2_start':
drivers/net/ethernet/qlogic/qed/qed_ll2.c:2159:1: error: the frame size of 1056 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
qed_ll2_start_ooo() already uses a dynamic allocation for the structure
to work around that problem, and we could do the same in qed_ll2_start()
as well as qed_roce_ll2_start(), but since the structure is only
used to pass a couple of initialization values here, it seems nicer
to replace it with a different structure.
Lacking any idea for better naming, I'm adding 'struct qed_ll2_conn',
which now contains all the initialization data, and this now simply
gets copied into struct qed_ll2_info rather than assigning all members
one by one.

kvm_s390_get_machine() populates the facility bitmap by copying bytes
from the host results that are stored in a 256 byte array in the prefix
page. The KVM code does use the size of the target buffer (2k), thus
copying and exposing unrelated kernel memory (mostly machine check
related logout data).
Let's use the size of the source buffer instead. This is ok, as the
target buffer will always be greater or equal than the source buffer as
the KVM internal buffers (and thus S390_ARCH_FAC_LIST_SIZE_BYTE) cover
the maximum possible size that is allowed by STFLE, which is 256
doublewords. All structures are zero allocated so we can leave bytes
256-2047 unchanged.
Add a similar fix for kvm_arch_init_vm().

The warn on is a bit too much, we will anyway set the dma mask if not set
previously.
The main reason for this fix is that 4.10-rc1 has a dwc3 change that
pass a parent sysdev dev pointer instead of setting the dma mask of
its xhci platform device. xhci platform driver can then get more
attributes from the sysdev than just the dma mask.
The usb core and xhci changes are not yet in 4.10, and a fix like
this was preferred instead of taking those big changes this late in
the rc-cycle.

In xen_swiotlb_map_page and xen_swiotlb_map_sg_attrs, if the original
page is not suitable, we swap it for another page from the swiotlb
pool.
In these cases, we don't update the previously calculated dma address
for the page before calling xen_dma_map_page. Thus, we end up calling
xen_dma_map_page passing the wrong dev_addr, resulting in
xen_dma_map_page mistakenly assuming that the page is foreign when it is
local.
Fix the bug by updating dev_addr appropriately.
This change has no effect on x86, because xen_dma_map_page is a stub

IBM bit 31 (for the rest of us - bit 0) is a reserved field in the
instruction definition of mtspr and mfspr. Hardware is encouraged to
(and does) ignore it.
As a result, if userspace executes an mtspr DSCR with the reserved bit
set, we get a DSCR facility unavailable exception. The kernel fails to
match against the expected value/mask, and we silently return to
userspace to try and re-execute the same mtspr DSCR instruction. We
loop forever until the process is killed.
We should do something here, and it seems mirroring what hardware does
is the better option vs killing the process. While here, relax the
matching of mfspr PVR too.

There is a hidden logic for acpi_tb_install_standard_table() as it can be
invoked from the boot stage and during runtime.
1. When it is invoked from the OS boot stage, the ACPICA mutex may not have
been initialized yet and so acpi_ut_acquire_mutex()/acpi_ut_release_mutex()
are not invoked in these code paths:
acpi_initialize_tables
acpi_tb_parse_root_table
acpi_tb_install_standard_table (4 invocations)
acpi_install_table
acpi_tb_install_standard_table
2. When it is invoked during the runtime, ACPICA mutex is used as
appropriate:
acpi_ex_load_op
acpi_tb_install_and_load_table
acpi_tb_install_standard_table
acpi_load_table
acpi_tb_install_and_load_table
acpi_tb_install_standard_table
The mutex is now used in acpi_tb_install_and_load_table(), while it actually
should be in acpi_tb_install_standard_table().
This introduces another problem in acpi_tb_install_standard_table() where
acpi_gbl_table_handler is invoked from and the lock contexts are thus not
consistent for the table handlers. This triggers a regression when
acpi_get_table()/acpi_put_table() start to hold table mutex during runtime.
The regression is noticed by LKP as new errors reported by ACPICA mutex
debugging facility.

The table mutex is held in acpi_tb_install_and_load_table() and is re-visited by
acpi_get_table().
Noticing that the early mutex requirement actually belongs to the OSL layer
and has already been handled in acpi_os_wait_semaphore()/acpi_os_signal_semaphore(),
the regression canbe fixed by removing this hidden logic from the ACPICA core
to the OS-specific code.

A side effect of keeping intel_pstate sysfs limits in sync with cpufreq
is that the now sysfs limits can't enforced under performance policy.
For example, if the max_perf_pct is changed from 100 to 80, this will call
intel_pstate_set_policy(), which will change the max_perf to 100 again for
performance policy. Same issue happens, when no_turbo is set.
This change calculates max and min frequency using sysfs performance
limits in intel_pstate_verify_policy() and adjusts policy limits by
calling cpufreq_verify_within_limits().
Also, it causes the setting of performance limits to be skipped if
no_turbo is set.
