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
there.

For ls1021a, and armv8 chasis 2 socs, sata ecc must be disabled.
If ecc register is not found in sata node in dts, report error.
This is a chip erratum described as bellow:
The Read DMA operations get early termination indication from the
controller. This issue is observed as CRC error in the status registers.
The issue is due to address collision at address 0 in the dual port
memory. The read is a dummy read to flush out the header, but due to
collision the controller logs the mbit error reported by the ECC check
logic. This results in the early termination of the Read DMA operation
by the controller. The issue happens to all the interface
speeds(GEN1/2/3) for all the products.
Workaround:
Disable ECC feature on those platforms.

irq_handle_thread()
Caching the fault register after a single I2C read may not keep an accurate
value.
Fix by doing two reads in irq_handle_thread() and using the cached value
elsewhere. If a safety timer fault later clears itself, we apparently don't get
an interrupt (INT), however other interrupts would refresh the register cache.
From the data sheet: "When a fault occurs, the charger device sends out INT
and keeps the fault state in REG09 until the host reads the fault register.
Before the host reads REG09 and all the faults are cleared, the charger
device would not send any INT upon new faults. In order to read the
current fault status, the host has to read REG09 two times consecutively.
The 1st reads fault register status from the last read [1] and the 2nd reads
the current fault register status."
[1] presumably a typo; should be "last fault"

Legacy RTC requires interrupt line 8 to be dedicated for it. On
Intel MID platforms the legacy PIC is absent and in order to make RTC
work we need to allocate interrupt separately.
Current solution brought by commit de1c2540aa4f does it in a wrong place,
and since it's done unconditionally for all x86 devices, some of them,
e.g. PNP based, might get it wrong because they execute the MID specific
code due to x86_platform.legacy.rtc flag being set.
Move intel_mid_legacy_rtc_init() to its own module and call it before x86 RTC
CMOS initialization.

not start. This change is neutral for DECON.

DECON_CMU register has reserved bits which should not be zeroed, otherwise
IP can behave strangely and cause IOMMU faults.
