In case of "host->bus_hz < slot->clock", divider value is
miscalculated. And clock divider register value is multiple of 2. If
calculated divider value is odd number, result can be over-clocking.

IDMAC may not be cleaned in driver probe if it has been already used in
boot time. So IDMAC needs sw reset newly. And DMA interface reset
precedes the internal DMAC reset. Additionally SDMMC_IDMAC_SWRESET is
replaced with magic code.

DTO interrupt can be later than transmit interrupt(IDMAC) in case of
write. Current handling of IDMAC interrupt sets EVENT_DATA_COMPLETE as
well as EVENT_XFER_COMPLETE regardless of DTO rising. This makes the
current request finish in tasklet and permits the next request even
though current data transfer is still in progress. As a result, sequence
is broken and lock-up happens. Setting EVENT_DATA_COMPLETE is not proper
after IDMAC interrupt. It should be taken after DTO interrupt is
generated.

SDIO_CCCR_IF[1:0] in SDIO card is used for card data bus width
setting as below:
00b: 1-bit bus
01b: Reserved
10b: 4-bit bus
11b: 8-bit bus (only for embedded SDIO)
And sdio_enable_wide is for setting data bus width as 4-bit.
But currently, it first reads the register, second OR' 1b with
SDIO_CCCR_IF[1], and then writes it back.
As we can see, this is based on such assumption that the
SDIO_CCCR_IF[0] is always 0. Apparently, this is not right.

In current Linux, percpu variable `vector_irq' is not cleared on
offlined cpus while disabling devices' irqs. If the cpu that has
the disabled irqs in vector_irq is hotplugged,
__setup_vector_irq() hits invalid irq vector and may crash.
This bug can be reproduced as following;
# echo 0 > /sys/devices/system/cpu/cpu7/online
# modprobe -r some_driver_using_interrupts # vector_irq@cpu7 uncleared
# echo 1 > /sys/devices/system/cpu/cpu7/online # kernel may crash
This patch fixes this bug by clearing vector_irq in
__clear_irq_vector() even if the cpu is offlined.

---[ end trace 320af5cb1cb60c5b ]---
The root cause seems to be the
default_send_IPI_mask_allbutself_phys() takes quite some time (I
measured it could be several ms) to complete sending NMIs to all
the other 23 CPUs, and for HZ=250/1000 system, the time is long
enough for a timer interrupt to happen, which will in turn
trigger to kick load balance to a stopped CPU and cause this
warning in native_smp_send_reschedule().
So disabling the local irq before stop_other_cpu() can fix this
problem (tested 25 times reboot ok), and it is fine as there
should be nobody caring the timer interrupt in such reboot
stage.
The latest 3.4 kernel slightly changes this behavior by sending
REBOOT_VECTOR first and only send NMI_VECTOR if the REBOOT_VCTOR
fails, and this patch is still needed to prevent the problem.

When hot-adding a CPU, the system outputs following messages
since node_to_cpumask_map[2] was not allocated memory.

node_to_cpumask_map[2] NULL
Pid: 0, comm: swapper/32 Tainted: G A 3.3.5-acd #21

[<ffffffff815052fb>] start_secondary+0x13/0xeb
The reason is that the bit of node 2 was not set at
numa_nodes_parsed. numa_nodes_parsed is set by only
acpi_numa_processor_affinity_init /
acpi_numa_x2apic_affinity_init. Thus even if hot-added memory
which is same PXM as hot-added CPU is written in ACPI SRAT
Table, if the hot-added CPU is not written in ACPI SRAT table,
numa_nodes_parsed is not set.
But according to ACPI Spec Rev 5.0, it says about ACPI SRAT
table as follows: This optional table provides information that
allows OSPM to associate processors and memory ranges, including
ranges of memory provided by hot-added memory devices, with
system localities / proximity domains and clock domains.
It means that ACPI SRAT table only provides information for CPUs
present at boot time and for memory including hot-added memory.
So hot-added memory is written in ACPI SRAT table, but hot-added
CPU is not written in it. Thus numa_nodes_parsed should be set
by not only acpi_numa_processor_affinity_init /
acpi_numa_x2apic_affinity_init but also
acpi_numa_memory_affinity_init for the case.
Additionally, if system has cpuless memory node,
acpi_numa_processor_affinity_init /
acpi_numa_x2apic_affinity_init cannot set numa_nodes_parseds
since these functions cannot find cpu description for the node.
In this case, numa_nodes_parsed needs to be set by
acpi_numa_memory_affinity_init.

Fix the x86 instruction decoder to decode bsr/bsf/jmpe with
operand-size prefix (66h). This fixes the test case failure
reported by Linus, attached below.
bsf/bsr/jmpe have a special encoding. Opcode map in
Intel Software Developers Manual vol2 says they have
TZCNT/LZCNT variants if it has F3h prefix. However, there
is no information if it has other 66h or F2h prefixes.
Current instruction decoder supposes that those are
bad instructions, but it actually accepts at least
operand-size prefixes.
H. Peter Anvin further explains:
" TZCNT/LZCNT are F3 + BSF/BSR exactly because the F2 and
F3 prefixes have historically been no-ops with most instructions.
This allows software to unconditionally use the prefixed versions
and get TZCNT/LZCNT on the processors that have them if they don't
care about the difference. "

The hardware bit IXGBE_RXD_STAT_VP appears to be set even when Rx

Working around this with a check for the feature flag bit. I
would welcome any better ideas or a pointer to exactly which

debugfs or omapdss debug support is turned off, and fixes a suspend related
crash.

Pull arm CMA fix from Marek Szyprowski:
"This removes the ARMv6+ CMA dependency and lets one use old, well-
tested dma-mapping implementation also on ARMv6+ systems without the
need to use EXPERIMENTAL stuff."
Russell King complained (rightly) about the experimental feature being
forced on by the ARM config.
Here CMA is "continuous memory allocator", not "cross-memory attach".
We really neet to stop using insane TLA's for things that aren't big
industry standards.

usb: fixes for v3.5-rc1
Here you have the first set of fixes for our v3.5-rc cycle.
It contains a set regression fixes caused by Ido's
usb_endpoint_descriptor usage rework and a build
fix to the musb driver caused by recent changes to
the DaVinci tree.
Nothing really major, the fixes are quite obvious.

This patch only affects mounting through "-t nfs4" since it doesn't set
up an nfs version to use in the mount data. The nfs client was trying
to mount using NFS v0, causing either a BUG() or a protocol not
supported message.

Or at least plug another gapping hole. Apparrently hw desingers only
moved the bit field, but did not bother ot re-enumerate the planes
when adding support for a 3rd pipe.
Discovered by i-g-t/flip_test.
This may or may not fix the reference bugzilla, because that one
smells like we have still larger fish to fry.
v2: Fixup the impossible case to catch programming errors, noticed by
Chris Wilson.

Pull cgroup fix from Tejun Heo:
"This fixes the possible premature superblock release on umount bug
mentioned during v3.5-rc1 pull request.
Originally, cgroup dentry destruction path assumed that cgroup dentry
didn't have any reference left after cgroup removal thus put super
during dentry removal. Now that there can be lingering dentry
references, this led to super being put with live dentries. This
patch fixes the problem by putting super ref on dentry release instead
of removal."

If a given interface combination doesn't contain
a required interface type then we missed checking
that and erroneously allowed it even though iface
type wasn't there at all. Add a check that makes
sure that all interface types are accounted for.

Linus reported that due to mac80211 failing to register
the device (due to WoWLAN) his machine crashed etc. as
we double-freed the vmalloc() firmware area. His patch
to fix it was very similar to this one but I noticed
that there's another bug in the area: we complete the
completion before starting, so since we're running in
a work struct context stop() could be called while in
the middle of start() which will almost certainly lead
to issues.
Make a modification similar to his to avoid the double-
free but also move the completion to another spot so it
is only done after start() either finished or failed so
that stop() can have a consistent state.

Pull embedded i2c update from Wolfram Sang:
"This only contains one new driver which had multiple dependencies
(pinctrl, i2c-mux-rework, new devm_* functions), so I decided to wait
for rc1. Plus, it had to wait a little for the ack of a devicetree
maintainer since the bindings were not trivial enough for me to pass
through.
So, given that, I hope there is still something like the "new driver
rule", so we could have the driver in 3.5 and people can start using
it. That would make merging support for some boards easier for 3.6
since the dependency on this driver is gone then."

This patch fixes bug in macro radix_tree_for_each_contig().
If radix_tree_next_slot() sees NULL in next slot it returns NULL, but following
radix_tree_next_chunk() switches iterating into next chunk. As result iterating
becomes non-contiguous and breaks vfs "splice" and all its users.
