According to SJA1000 documentation the location of error is available
regardless of an error type. Therefore it should always be forwarded to
SocketCAN.

As akcipher uses an SG interface, you must not use vmalloc memory
as input for it. This patch fixes testmgr to copy the vmalloc
test vectors to kmalloc memory before running the test.
This patch also removes a superfluous sg_virt call in do_test_rsa.

Aspeed devices are a common Baseboard Management Controller (BMC)
system on chip containing an ARM9 or ARM11 core, off-chip DDR RAM and
support for a large number of peripherals.
This patch adds basic support for the ast2400 and ast2500 machines,
capable of booting to a prompt in QEMU (-M palmetto-bmc), on an
Palmetto OpenPower development machine, and on the ast2500 EVB.

SMSC MFD driver does not add any MFD child devices via

net/mlx5e: Kconfig fixes for VxLAN
Reposting to net the build errors fixes posted by Arnd last week.
Originally Arnd posted those fixes to net-next, while the issue
is also seen in net. For net-next a different approach is required
for fixing the issue as VXLAN and Device Drivers are no longer
dependent, but there is no harm for those fixes to get into net-next.
Optionally, once net is merged into net-next we can
Revert "net/mlx5e: make VXLAN support conditional" as the
CONFIG_MLX5_CORE_EN_VXLAN will no longer be required.

VXLAN can be disabled at compile-time or it can be a loadable
module while mlx5 is built-in, which leads to a link error:
drivers/net/built-in.o: In function `mlx5e_create_netdev':
ntb_netdev.c:(.text+0x106de4): undefined reference to `vxlan_get_rx_port'
This avoids the link error and makes the vxlan code optional,
like the other ethernet drivers do as well.

This reverts commit 69976fb1045850a742deb9790ea49cbc6f497531.
We cannot select VXLAN when IPv4 support is disabled, that just gives
us additional build errors, including:
warning: (MLX5_CORE_EN) selects VXLAN which has unmet direct dependencies (NETDEVICES && NET_CORE && INET)

The MACsec standard mentions a key identifier for each key, but
doesn't specify anything about it, so I arbitrarily chose 64 bits.
IEEE 802.1X-2010 specifies MKA (MACsec Key Agreement), and defines the
key identifier to be 128 bits (96 bits "member identifier" + 32 bits
"key number").

Refactor tcp_skb_cb to create two overlaping areas to store
state for incoming or outgoing skbs based on comments by
Neal Cardwell to tcp_nv patch:
AFAICT this patch would not require an increase in the size of
sk_buff cb[] if it were to take advantage of the fact that the
tcp_skb_cb header.h4 and header.h6 fields are only used in the packet
reception code path, and this in_flight field is only used on the
transmit side.

Since the CTOP is SMT hardware multi-threaded, we need to hint
the HW that now will be a very good time to do a hardware
thread context switching. This is done by issuing the schd.rw
instruction (binary coded here so as to not require specific
revision of GCC to build the kernel).
sched.rw means that Thread becomes eligible for execution by
the threads scheduler after all pending read/write
transactions were completed.
Implementing cpu_relax_lowlatency() with barrier()
Since with current semantics of cpu_relax() it may take a
while till yielded CPU will get back.

If we hold rwlock and interrupt occures we may
end up spinning on it for ever during softirq.
Note that this lock is an internal lock
and since the lock is free to be used from any context,
the lock needs to be IRQ-safe.
Below you may see an example for interrupt we get while
nl_table_lock is holding its rw->lock_mutex and we spinned
on it for ever.
The concept for the fix was taken from SPARC.

On ARC, lower 2G of address space is translated and used for
- user vaddr space (region 0 to 5)
- unused kernel-user gutter (region 6)
- kernel vaddr space (region 7)
where each region simply represents 256MB of address space.
The kernel vaddr space of 256MB is used to implement vmalloc, modules
So far this was enough, but not on EZChip system with 4K CPUs (given
that per cpu mechanism uses vmalloc for allocating chunks)
So allow VMALLOC_SIZE to be configurable by expanding down into the unused
kernel-user gutter region which at default 256M was excessive anyways.
Also use _BITUL() to fix a build error since PGDIR_SIZE cannot use "1UL"
as called from assembly code in mm/tlbex.S
