crypto: talitos - corrrectly handle zero-length assoc data

talitos does not handle well zero-length assoc data. From dmesg:
talitos ffe30000.crypto: master data transfer error
talitos ffe30000.crypto: gather return/length error

Check whether assoc data is provided by inspecting assoclen,
not assoc pointer.
This is needed in order to pass testmgr tests.

crypto: s390 - Fix aes-xts parameter corruption

Some s390 crypto algorithms incorrectly use the crypto_tfm structure to
store private data. As the tfm can be shared among multiple threads, this
can result in data corruption.

This patch fixes aes-xts by moving the xts and pcc parameter blocks from
the tfm onto the stack (48 + 96 bytes).

crypto: ccm - Fix handling of zero plaintext when computing mac

There are cases when cryptlen can be zero in crypto_ccm_auth():
-encryptiom: input scatterlist length is zero (no plaintext)
-decryption: input scatterlist contains only the mac
plus the condition of having different source and destination buffers
(or else scatterlist length = max(plaintext_len, ciphertext_len)).

These are not handled correctly, leading to crashes like:

irqchip: Gic: fix boot for chained gics

As of c0114709ed: "irqchip: gic: Perform the gic_secondary_init() call
via CPU notifier", booting on a platform with chained gics (e.g.
Realview EB ARM11MPCore) will result in the gic_cpu_notifier being
registered twice, corrupting the cpu notifier list and rendering the
platform unbootable.

This patch ensures that we only register the notifier for the first
gic, allowing platforms with chained gics to boot. At the same time we
limit the pointlessly duplicated calls to set_smp_cross_call and
set_handle_irq to the first gic registered.

efivars, efi-pstore: Hold off deletion of sysfs entry until the scan is completed

Currently, when mounting pstore file system, a read callback of
efi_pstore driver runs mutiple times as below.

- In the first read callback, scan efivar_sysfs_list from head and pass
  a kmsg buffer of a entry to an upper pstore layer.
- In the second read callback, rescan efivar_sysfs_list from the entry
  and pass another kmsg buffer to it.
- Repeat the scan and pass until the end of efivar_sysfs_list.

In this process, an entry is read across the multiple read function
calls. To avoid race between the read and erasion, the whole process
above is protected by a spinlock, holding in open() and releasing in
close().

At the same time, kmemdup() is called to pass the buffer to pstore
filesystem during it. And then, it causes a following lockdep warning.

To make the dynamic memory allocation runnable without taking spinlock,
holding off a deletion of sysfs entry if it happens while scanning it
via efi_pstore, and deleting it after the scan is completed.

To implement it, this patch introduces two flags, scanning and deleting,
to efivar_entry.

On the code basis, it seems that all the scanning and deleting logic is
not needed because __efivars->lock are not dropped when reading from the
EFI variable store.

But, the scanning and deleting logic is still needed because an
efi-pstore and a pstore filesystem works as follows.

In case an entry(A) is found, the pointer is saved to psi->data.  And
efi_pstore_read() passes the entry(A) to a pstore filesystem by
releasing  __efivars->lock.

And then, the pstore filesystem calls efi_pstore_read() again and the
same entry(A), which is saved to psi->data, is used for resuming to scan
a sysfs-list.

So, to protect the entry(A), the logic is needed.

x86/efi: Fix earlyprintk off-by-one bug

Dave reported seeing the following incorrect output on his Thinkpad T420
when using earlyprintk=efi,

[    0.000000] efi: EFI v2.00 by Lenovo
                    ACPI=0xdabfe000  ACPI 2.0=0xdabfe014 SMBIOS=0xdaa9e000

The output should be on one line, not split over two. The cause is an
off-by-one error when checking that the efi_y coordinate hasn't been
incremented out of bounds.

drm/i915: Fix pipe CSC post offset calculation

We were miscalculating the pipe CSC post offset for the full->limited
range conversion. The resulting post offset was double what it was
supposed to be, which caused blacks to come out grey when using
limited range output on HSW+.

wow no idea how I got this far without seeing this,
leaking the entries in the list makes kmalloc-64 slab grow.

diag: warn about missing first netlink attribute

The first netlink attribute (value 0) must always be defined as none/unspec.
This is correctly done in inet_diag.h, but other diag interfaces are wrong.

Because we cannot change an existing API, I add a comment to point the mistake
and avoid to propagate it in a new diag API in the future.

bonding: disable arp and enable mii monitoring when bond change to no uses arp mode

Because the ARP monitoring is not support for 802.3ad, but I still
could change the mode to 802.3ad from ab mode while ARP monitoring
is running, it is incorrect.

So add a check for 802.3ad in bonding_store_mode to fix the problem,
and make a new macro BOND_NO_USES_ARP() to simplify the code.

v2: according to the Dan Williams's suggestion, bond mode is the most
    important bond option, it should override any of the other sub-options.
    So when the mode is changed, the conficting values should be cleared
    or reset, otherwise the user has to duplicate more operations to modify
    the logic. I disable the arp and enable mii monitoring when the bond mode
    is changed to AB, TB and 8023AD if the arp interval is true.

v3: according to the Nik's suggestion, the default value of miimon should need
    a name, there is several place to use it, and the bond_store_arp_interval()
    could use micro BOND_NO_USES_ARP to make the code more simpify.
