Currently we have similar code for (txp && rxp), (txp && !rxp), (!rxp & txp),
and (!txp && !rxp) cases. This patch refactors the code a bit to avoid
duplicate similar code.

There is no need to force selection of TI EDMA DMA engine
driver when DaVinci SPI driver is selected. The driver
builds just fine even with CONFIG_TI_EDMA disabled.
Forcing this selection causes warnings of the sort:
warning: (ARCH_KEYSTONE && SPI_DAVINCI) selects TI_EDMA which has unmet direct dependencies (DMADEVICES && (ARCH_DAVINCI || ARCH_OMAP || ARCH_KEYSTONE))
This reverts commit b5f14330590118e6a0659255476c0f24ab681e05.

Commit e13ac47bec20 (spi: Use stable dev_name for ACPI enumerated SPI
slaves) changed the SPI device naming to be based on ACPI device name
instead of carrying bus number and chip select for devices enumerated
from ACPI namespace.
In case of a buggy BIOS that lists multiple SPI devices sharing the same
chip select (even though they should use different) the current code fails
to detect that and allows the devices to be added to the bus.
Fix this by walking through the bus and comparing spi->chip_select instead
of device name. This should work regardless what the device name will be in
future.

Helge Deller noted a few weeks ago problems with the AIO support on
parisc. This change is the result of numerous iterations on how best to
deal with this problem.
The solution adopted here is to provide full cache coherency in a
uniform manner on all parisc systems. This involves calling
flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on
kunmap operations. As a result, the copy_user_page() and
clear_user_page() functions can be removed and the overall code is
simpler.
The change ensures that both userspace and kernel aliases to a mapped
page are invalidated and flushed. This is necessary for the correct
operation of PA8800 and PA8900 based systems which do not support
inequivalent aliases.
With this change, I have observed no cache related issues on c8000 and
rp3440. It is now possible for example to do kernel builds with "-j64"
on four way systems.
On systems using XFS file systems, the patch recently posted by Mikulas
Patocka to "fix crash using XFS on loopback" is needed to avoid a hang
caused by an uninitialized lock passed to flush_dcache_page() in the
page struct.

Commit 6d9252bd9a4bb (clk: Add support for power of two type dividers)
merged in v3.6 added the _get_val function to convert a divisor value to
a register field value depending on the flags. However it used the type
u8 for the div field, causing divisors larger than 255 to be masked
and the resultant clock rate to be too high.
E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down
to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This
was masked to 238 (0xee) resulting in a frequency of 103.26KHz.

The only BIOS on record that needs the 14 offset has a bios major
version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18
offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the
bios major version, look at the BMP version. BIOSes with BMP version 0
do not contain a detectable script, so always return 0 for them.

When we pull a received packet from a link's 'deferred packets' queue
for processing, its 'next' pointer is not cleared, and still refers to
the next packet in that queue, if any. This is incorrect, but caused

This happens when the last fragment of a message has passed through the
the receiving link's 'deferred packets' queue, and at least one other
packet was added to that queue while it was there. After the fragment
chain with the complete message has been successfully delivered to the
receiving socket, it is released. Since 'next' pointer of the last
fragment in the released chain now is non-NULL, we get the crash shown
above.
We fix this by clearing the 'next' pointer of all received packets,
including those being pulled from the 'deferred' queue, before they
undergo any further processing.

Jani for co-maintainer!
Jani has been a really active bug-scrubber in the past few months.
I've asked him whether he wants to do this in a more official capacity
and he agreed. I've already chatted with Dave and Jesse and they
support this.
Note that everyone can't now just relax because "Jani will do all the
bug scrubbing" - au contraire expect more nagging and poking now that
we have more bandwidth.
Longer-term the plan is to share more of the maintainer duties, but we
need to fix up the infrastructure a bit first (like moving the git
repo to a common location).
While at it also add the newly set-up patchwork instance.

br_multicast_set_hash_max() is called from process context in
net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function.
br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock),
which can deadlock the CPU if a softirq that also tries to take the
same lock interrupts br_multicast_set_hash_max() while the lock is
held . This can happen quite easily when any of the bridge multicast
timers expire, which try to take the same lock.
The fix here is to use spin_lock_bh(), preventing other softirqs from
executing on this CPU.
Steps to reproduce:
1. Create a bridge with several interfaces (I used 4).
2. Set the "multicast query interval" to a low number, like 2.
3. Enable the bridge as a multicast querier.
4. Repeatedly set the bridge hash_max parameter via sysfs.
# brctl addbr br0
# brctl addif br0 eth1 eth2 eth3 eth4
# brctl setmcqi br0 2
# brctl setmcquerier br0 1
# while true ; do echo 4096 > /sys/class/net/br0/bridge/hash_max; done

It does not make sense to create an anycast address for an /128-prefix.
Suppress it.
As 32019e651c6fce ("ipv6: Do not leave router anycast address for /127
prefixes.") shows we also may not leave them, because we could accidentally
remove an anycast address the user has allocated or got added via another
prefix.

The existing serial state notification handling expected older Option
devices, having a hardcoded assumption that the Modem port was always
USB interface #2. That isn't true for devices from the past few years.
hso_serial_state_notification is a local cache of a USB Communications
Interface Class SERIAL_STATE notification from the device, and the
USB CDC specification (section 6.3, table 67 "Class-Specific Notifications")
defines wIndex as the USB interface the event applies to. For hso
devices this will always be the Modem port, as the Modem port is the
only port which is set up to receive them by the driver.
So instead of always expecting USB interface #2, instead validate the
notification with the actual USB interface number of the Modem port.

Commit f5a44db5d2 introduced a regression on filesystems created with
the bigalloc feature (cluster size > blocksize). It causes xfstests
generic/006 and /013 to fail with an unexpected JBD2 failure and
transaction abort that leaves the test file system in a read only state.
Other xfstests run on bigalloc file systems are likely to fail as well.
The cause is the accidental use of a cluster mask where a cluster
offset was needed in ext4_ext_map_blocks().

Commit 5901b6be885e attempted to introduce IPv6 support into
IRC NAT helper. By doing so, the following code seemed to be removed
by accident:
ip = ntohl(exp->master->tuplehash[IP_CT_DIR_REPLY].tuple.dst.u3.ip);
sprintf(buffer, "%u %u", ip, port);
pr_debug("nf_nat_irc: inserting '%s' == %pI4, port %u\n", buffer, &ip, port);
This leads to the fact that buffer[] was left uninitialized and
contained some stack value. When we call nf_nat_mangle_tcp_packet(),
we call strlen(buffer) on excatly this uninitialized buffer. If we
are unlucky and the skb has enough tailroom, we overwrite resp. leak
contents with values that sit on our stack into the packet and send
that out to the receiver.
Since the rather informal DCC spec [1] does not seem to specify
IPv6 support right now, we log such occurences so that admins can
act accordingly, and drop the packet. I've looked into XChat source,
and IPv6 is not supported there: addresses are in u32 and print
via %u format string.
Therefore, restore old behaviour as in IPv4, use snprintf(). The
IRC helper does not support IPv6 by now. By this, we can safely use
strlen(buffer) in nf_nat_mangle_tcp_packet() and prevent a buffer
overflow. Also simplify some code as we now have ct variable anyway.

This corrects a problem in spi_pump_messages() that leads to an spi
message hanging forever when a call to transfer_one_message() fails.
This failure occurs in my MCP2210 driver when the cs_change bit is set
on the last transfer in a message, an operation which the hardware does
not support.
Rationale
Since the transfer_one_message() returns an int, we must presume that it
may fail. If transfer_one_message() should never fail, it should return
void. Thus, calls to transfer_one_message() should properly manage a
failure.
