Add a requested speed variable to the link_status struct to store the
last speeds we requested from the firmware (the speeds the FW will be
advertising with if autoneg is enabled).
Use the advertised speed settings in get_settings in ethtool now that
we have it. Also set the requested speed settings in set_settings in
ethtool as they are requested and initialize them in probe based on what
the firmware remembers as the last requested speeds.
To accommodate some longer lines in this new code, and improve
readability I have added two functions i40e_get_settings_link_up
and i40e_get_settings_link_down which get_settings now calls first.
It then does all of the settings that happen regardless of link
state. Some PHY types that supported the same settings were also combined.
Also update the copyright year.

The function i40e_debug_aq() prints information helpful in debugging
admin queue commands, but it doesn't do so correctly on big endian machines.
This patch adds the appropriate LExx_TO_CPU wrappers for big endian

The patch 237fead61998: "[PATCH] ecryptfs: fs/Makefile and
fs/Kconfig" from Oct 4, 2006, leads to the following static checker
warning:
fs/ecryptfs/crypto.c:846 ecryptfs_new_file_context()
error: off-by-one overflow 'crypt_stat->cipher' size 32. rl = '0-32'
There is a mismatch between the size of ecryptfs_crypt_stat.cipher
and ecryptfs_mount_crypt_stat.global_default_cipher_name causing the
copy of the cipher name to cause a off-by-one string copy error. This
fix ensures the space reserved for this string is the same size including
the trailing zero at the end throughout ecryptfs.
This fix avoids increasing the size of ecryptfs_crypt_stat.cipher
and also ecryptfs_parse_tag_70_packet_silly_stack.cipher_string and instead
reduces the of ECRYPTFS_MAX_CIPHER_NAME_SIZE to 31 and includes the + 1 for
the end of string terminator.
NOTE: An overflow is not possible in practice since the value copied
into global_default_cipher_name is validated by
ecryptfs_code_for_cipher_string() at mount time. None of the allowed
cipher strings are long enough to cause the potential buffer overflow
fixed by this patch.

Since __ATTR_PREALLOC was introduced in v3.19-rc1~78^2~18
it can now be used by md.
This ensure that writing to these sysfs attributes will never
block due to a memory allocation.
Such blocking could become a deadlock if mdmon is trying to
reconfigure an array after a failure prior to re-enabling writes.

When we have more than 1 drive failure, it's possible we start
rebuild one drive while leaving another faulty drive in array.
To determine whether array will be optimal after building, current
code only check whether a drive is missing, which could potentially
lead to data corruption. This patch is to add checking Faulty flag.

When a drive is marked write-mostly it should only be the
target of reads if there is no other option.
This behaviour was broken by
commit 9dedf60313fa4dddfd5b9b226a0ef12a512bf9dc
md/raid1: read balance chooses idlest disk for SSD
which causes a write-mostly device to be *preferred* is some cases.
Restore correct behaviour by checking and setting
best_dist_disk and best_pending_disk rather than best_disk.
We only need to test one of these as they are both changed
from -1 or >=0 at the same time.
As we leave min_pending and best_dist unchanged, any non-write-mostly
device will appear better than the write-mostly device.

If the pending indexes are released /after/ pushing the Tx response
then a stale pending index may be used if a new Tx request is
immediately pushed by the frontend. The may cause various WARNINGs or
BUGs if the stale pending index is actually still in use.
Fix this by releasing the pending index before pushing the Tx
response.
The full barrier for the pending ring update is not required since the
the Tx response push already has a suitable write barrier.

Before da413eec729d ("packet: Fixed TPACKET V3 to signal poll when block is
closed rather than every packet") poll listening for an af_packet socket was
not signaled if there was no packets to process. After the patch poll is
signaled evety time when block retire timer expires. That happens because
af_packet closes the current block on timeout even if the block is empty.
Passing empty blocks to the user not only wastes CPU but also wastes ring
buffer space increasing probability of packets dropping on small timeouts.

The Churn Detection machines detect the situation where a port is operable,
but the Actor and Partner have not attached the link to an Aggregator and
brought the link into operation within a bound time period. Under normal
operation of the LACP, agreement between Actor and Partner should be reached
very rapidly. Continued failure to reach agreement can be symptomatic of
device failure.

According to SMBIOSv3 specification the length of DMI table can be
up to 32bits wide. So use appropriate type to avoid overflow.
It's obvious that dmi_num theoretically can be more than u16 also,
so it's can be changed to u32 or at least it's better to use int
instead of u16, but on that moment I cannot imagine dmi structure
count more than 65535 and it can require changing type of vars that
work with it. So I didn't correct it.

While adding support loading kernel and initrd above 4G to grub2 in legacy
mode, I was referring to efi_high_alloc().
That will allocate buffer for kernel and then initrd, and initrd will
use kernel buffer start as limit.
During testing found two buffers will be overlapped when initrd size is
very big like 400M.
It turns out efi_high_alloc() boundary checking is not right.
end - size will be the new start, and should not compare new
start with max, we need to make sure end is smaller than max.
[ Basically, with the current efi_high_alloc() code it's possible to
allocate memory above 'max', because efi_high_alloc() doesn't check
that the tail of the allocation is below 'max'.
If you have an EFI memory map with a single entry that looks like so,
[0xc0000000-0xc0004000]
And want to allocate 0x3000 bytes below 0xc0003000 the current code
will allocate [0xc0001000-0xc0004000], not [0xc0000000-0xc0003000]
like you would expect. - Matt ]

While at it switch over to IS_ENABLED for thermal macros
to allow for thermal framework to be built as framework

we enabled Extcon USB gpio to tackle the USB ID pin and get

But the extcon-gpio-usb driver [1] didn't make it into v4.0

Offset for smc91x must be zero otherwise smc91x linux kernel driver does not

The 0x300 offset was used to supress a warning the smsc911x

be the EEPROM default. As only three address lines are
connected both 0 and 0x300 will work just fine with 0 being

Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the USB completely because of an unconfigured USB phy, and
I only tested it to make sure the Mentor chips are detected and
clocked without a phy.
After testing the USB with actual devices I noticed a few issues
that should be fixed to avoid confusion:
- The USB id pin on dm8168-evm is hardwired and can be changed
only by software. As there are two USB-A type connectors, let's
start both in host mode instead of otg.
- The Mentor core is configured in such a way on dm8168-evm that
it's not capable of multipoint at least on revision c board
that I have.
- We need ranges for the syscon to properly set up the phy as
children of the SCM syscon area.
- Let's not disable the second interface, the board specific
dts files can do that if really needed. Most boards should
just keep it enabled to ensure the device is idled properly.
Note that also a phy and several musb fixes are still needed to
make the USB to work properly in addition to this fix.

Intel Wired LAN Driver Updates 2015-02-23
This series contains updates to e1000e, igbvf, i40e and i40evf.
David adds support for i219 devices to the e1000e driver.
Jeff (me) provides two patches to cleanup igbvf, first cleans up the
whitespace issues found and the second cleans up the usage of msleep(),
min() and max() with usleep_range(), min_t() and max_t() respectively.
Kamil updates the shadow RAM read/write functions by refactoring them
to prepare for future work.
Shannon renames the debugfs command "clear_stats pf" to clear_stats port"
to clarify what the function really does.
Mitch refactors the receive routine, by splitting the receive hot path
code into two, one for packet split and one for single buffer, which
improves receive performance. Disables NAPI polling sooner when closing
the interface to fix an occasional panic during close which was
caused by the driver trying to delete and clean rings at the same time.
Also refactors reset for i40evf, since a recent change to the shutdown
flow messed up the reset flow. Since i40evf_down() now holds the
critical section lock, we cannot call it from the reset handler, which
also holds the lock.
Nicholas restricts the virtual channel opcodes should remain consistent
between updates to the opcode enum.
Neerav converts the VSI connection type to use a #define instead of
using a magic number.
Anjali updates the registers file to remove registers no longer available.
Also fixes the EMPR interrupt handling, so that we won't trigger another
EMPR when we receive an EMPR event.
Catherine cleans up the variable an_enable since it was set and never
used.
Greg fixes the netdev op that allows the operator to turn MAC/VLAN
spoof checking on and off so that it includes the flag for VLAN spoof
checking.

2. rework Tx queue init
3. precalculate TxCB->bd_addr
4. rename bcmgenet_hw_params->bds_cnt and GENET_DEFAULT_BD_CNT

bcmgenet_hw_params->bds_cnt and GENET_DEFAULT_BD_CNT are used only in Tx init.
Rename them accordingly:
- bcmgenet_hw_params->bds_cnt => bcmgenet_hw_params->tx_bds_per_q
- GENET_DEFAULT_BD_CNT => GENET_Q16_TX_BD_CNT

There is 1-to-1 mapping between TxCBs and TxBDs. Precalculate TxCB->bd_addr
once in bcmgenet_init_dma() instead of doing it over and over needlessly in
bcmgenet_get_txcb().

In order to support an older USB cradle by Denso, I added its vendor- and product-ID to the array of usb_device_id acm_ids. In this way cdc-acm feels responsible for this cradle. The related /dev/ttyACM node is being created properly, and the data transfer works.
However, later cradle models by Denso do have proper descriptors, so the patch is not required for these. At the same time both the older and the later model have the same vendor- and product-ID, but they both work with the patched driver.
Declaration of the Denso cradles I tested:
- both models have the same IDs: vendorID 0x076d, productID 0x0006
- older model: Denso CU-321 (descriptors not properly set)
- later model: Denso CU-821 (with proper descriptors)
