Since commit 543bb25 "spi: add ability to validate xfer->bits_per_word in SPI
core", the driver can set bits_per_word_mask for the master then the SPI core
will reject transfers that attempt to use an unsupported bits_per_word value.
So we can remove octeon_spi_validate_bpw() and let SPI core handle the checking.

It turns out that we missed increasing needed pages in BRK to
mapping initial 2M and [0,1M) when we switched to use the #PF
handler to set memory mappings:

> x86, 64bit: Use a #PF handler to materialize early mappings on demand
Before that, we had the maping from [0,512M) in head_64.S, and we
can spare two pages [0-1M). After that change, we can not reuse
pages anymore.
When we have more than 512M ram, we need an extra page for pgd page
with [512G, 1024g).
Increase pages in BRK for page table to solve the boot crash.

Prevent crash_kexec() from deadlocking on ioapic_lock. When
crash_kexec() is executed on a CPU, the CPU will take ioapic_lock
in disable_IO_APIC(). So if the cpu gets an NMI while locking
ioapic_lock, a deadlock will happen.
In this patch, ioapic_lock is zapped/initialized before disable_IO_APIC().
You can reproduce this deadlock the following way:
1. Add mdelay(1000) after raw_spin_lock_irqsave() in
native_ioapic_set_affinity()@arch/x86/kernel/apic/io_apic.c
Although the deadlock can occur without this modification, it will increase
the potential of the deadlock problem.
2. Build and install the kernel
3. Set up the OS which will run panic() and kexec when NMI is injected
# echo "kernel.unknown_nmi_panic=1" >> /etc/sysctl.conf
# vim /etc/default/grub
add "nmi_watchdog=0 crashkernel=256M" in GRUB_CMDLINE_LINUX line
# grub2-mkconfig
4. Reboot the OS
5. Run following command for each vcpu on the guest
# while true; do echo <CPU num> > /proc/irq/<IO-APIC-edge or IO-APIC-fasteoi>/smp_affinitity; done;
By running this command, cpus will get ioapic_lock for setting affinity.
6. Inject NMI (push a dump button or execute 'virsh inject-nmi <domain>' if you
use VM). After injecting NMI, panic() is called in an nmi-handler context.
Then, kexec will normally run in panic(), but the operation will be stopped
by deadlock on ioapic_lock in crash_kexec()->machine_crash_shutdown()->
native_machine_crash_shutdown()->disable_IO_APIC()->clear_IO_APIC()->
clear_IO_APIC_pin()->ioapic_read_entry().

There are possible HW configurations in which PFs will have SR-IOV capability
but will have Max VFs set to 0 - this happens when there are Multi-Function
devices where the VFs are allocated to only some of the PFs.
DMAE is configured to support VFs only if the configuring PF has supported VFs.
In case the first PF to be loaded will be one without supported VFs, it will
not configure DMAE to the VF-supporting mode. When VFs of other PFs will be
loaded later on, they will not be able to communicate with their PF.
This changes the requirement for configuring DMAE for VF-supporting mode;
If the device has SR-IOV capabilities there must be some PF that has
max supported VFs > 0, thus it will configure the DMAE for supporting VFs.

Since SR-IOV can be activated dynamically and iproute2 can be called
asynchronously, the various callbacks need a robust sanity check before
attempting to access the SR-IOV database and members since there are numerous
states in which it can find the driver (e.g., PF is down, sriov was not enabled
yet, VF is down, etc.).
In many of the states the callback result will be null pointer dereference.

After notification that DCBX configuration has ended arrived to the driver,
the driver configured the FW/HW in sleepless context.
As a result, it was possible to reach a race (mostly with CNIC registration)
in which the configuration will return a timeout, failing to set the DCBX
results correctly.
This patch moves the configuration following the DCBX end into the slowpath
RTNL task (i.e., sleepless context protected by the RTNL lock), allowing the
configuration to cope with such races.

Since commit 3deb816 "bnx2x: Add a periodic task for link PHY events"
link state changes can be detected not only via the attention flow but also
from the periodic task.
If the link state will change in such a manner (i.e., via the periodic task),
dropless flow-control will not be configured.
This patch remedies the issue, adding the missing configuration to all required
flows.

It is not allowed for an ipv6 packet to contain multiple fragmentation
headers. So discard packets which were already reassembled by
fragmentation logic and send back a parameter problem icmp.

Because of the max_addresses check attackers were able to disable privacy
extensions on an interface by creating enough autoconfigured addresses:
<http://seclists.org/oss-sec/2012/q4/292>
But the check is not actually needed: max_addresses protects the
kernel to install too many ipv6 addresses on an interface and guards
addrconf_prefix_rcv to install further addresses as soon as this limit
is reached. We only generate temporary addresses in direct response of
a new address showing up. As soon as we filled up the maximum number of
addresses of an interface, we stop installing more addresses and thus
also stop generating more temp addresses.
Even if the attacker tries to generate a lot of temporary addresses
by announcing a prefix and removing it again (lifetime == 0) we won't
install more temp addresses, because the temporary addresses do count
to the maximum number of addresses, thus we would stop installing new
autoconfigured addresses when the limit is reached.
This patch fixes CVE-2013-0343 (but other layer-2 attacks are still
possible).
Thanks to Ding Tianhong to bring this topic up again.

Note that this commit also updates the formatting of serveral of the
bibtex entries to conform to that of my .bib files. I started
accumulating entries back in the 1980s, back when bibtex insisted
that comma (",") was a separator, not a terminator. This rule forced
commas to the fronts of lines. 25 years later, bibtex allows commas
to be terminators, but I am too lazy to rework all my .bib files.
Keeping the same format as my .bib files allows my to simply
incorporate my RCU.bib file into Documentation/RCU/RTFP.txt, which
is much easier than my earlier practice of keeping track of what
had changed and adding individual entries. (I sometimes find relevant
papers that were published some years back, for example.)
In addition, this change adds entries for papers published in the
last year or so.

if we get the valid dma channels from dts, move to use dmaengine to do
rx/tx. because the dma hardware requires dma address and length to be
4bytes aligned, in this driver, we will still use PIO for non-aligned
bytes, and use dma for aligned bytes.
for rx, to keep the dmaengine always active, we use double-buffer, so
we issue two dma_desc at first, and maintain the status of both
1. dma transfer done: update in rx dma finish callback
2. dma buffer is inserted into tty: update in rx dma finish tasklet and
rx timeout tasklet
so we re-issue the dma_desc only if both 1&2 are finished.
for tx, as we know the actual length for every transfer, we don't need
the above double buffering.

and various manual modifications to move associated calls to
platform_get_resource closer to the resulting call to devm_ioremap_resource

The initialization of port->mapbase is also moved lower, to take advantage

When a serial port is configured for RTS/CTS flow control, serial core
will disable the transmitter if it observes CTS is de-asserted. This is
perfectly reasonable and appropriate when the UART lacks the ability to
automatically perform CTS flow control.
However, if the UART hardware can manage flow control automatically, it
is important that software not get involved. When the DesignWare UART
enables 16C750 style auto-RTS/CTS it stops generating interrupts for
changes in CTS state so software mostly stays out of the way. However,
it does report the true state of CTS in the MSR so software may notice
it is de-asserted and respond by improperly disabling the transmitter.
Once this happens the transmitter will be blocked forever.
To avoid this situation, we simply lie to the 8250 and serial core by
reporting that CTS is asserted whenever auto-RTS/CTS mode is enabled.

xhci: Step 2 to fix usb-linus and usb-next.
Hi Greg,
This is the first of two steps to fix your usb-linus and usb-next trees.
As I mentioned, commit 4fae6f0fa86f92e6bc7429371b1e177ad0aaac66 "USB:
handle LPM errors during device suspend correctly" was incorrectly added
to usb-next when it should have been added to usb-linus and marked for
stable.
Two port power off bug fixes touch the same code that patch touches, but
it's not easy to simply move commit 4fae6f0f patch to usb-linus because
commit 28e861658e23ca94692f98e245d254c75c8088a7 "USB: refactor code for
enabling/disabling remote wakeup" also touched those code sections.
I propose a two step process to fix this:
1. Pull these four patches into usb-linus.
2. Revert commit 28e861658e23ca94692f98e245d254c75c8088a7 from usb-next.
Merge usb-linus into usb-next, and resolve the conflicts.
I will be sending pull requests for these steps.
This pull request is step two.

In the previous commit, Richard Genoud fixed proc_root_readdir(), which
had lost the check for whether all of the non-process /proc entries had
been returned or not.
But that in turn exposed _another_ bug, namely that the original readdir
conversion patch had yet another problem: it had lost the return value
of proc_readdir_de(), so now checking whether it had completed
successfully or not didn't actually work right anyway.
This reinstates the non-zero return for the "end of base entries" that
had also gotten lost in commit f0c3b5093add ("[readdir] convert
procfs"). So now you get all the base entries *and* you get all the
process entries, regardless of getdents buffer size.
(Side note: the Linux "getdents" manual page actually has a nice example
application for testing getdents, which can be easily modified to use
different buffers. Who knew? Man-pages can be useful)
