Bit 2 of status register 2 on MAX6696 (external diode 2 open)

Also display a message in the alert handler if the condition
is encountered.
Even though not all overtemperature conditions cause ALERT
to be set, we should not ignore them in the alert handler.

Openrisc's private vmlinux.h duplicates a few definitions that are already
provided by asm-generic/sections.h. The former is used by setup.c only,
while the latter is already used everywhere else.

- Include <asm/sections.h>,
- Remove the (slightly different) extern declarations,

The short <blurb> is that the tracing facility (just one function) has

Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver
"is used to translate physical to machine and machine to physical

booting under hardware without proper IOMMU.
There are also bug-fixes, cleanups, compile warning fixes, etc.
The commit times for some of the commits is a bit fresh - that is b/c
we wanted to make sure we have the Ack's from the ARM folks - which
with the string of back-to-back conferences took a bit of time. Rest
assured - the code has been stewing in #linux-next for some time.

ERROR: "__divdi3" [fs/hfsplus/hfsplus.ko] undefined!
Introduced by commit 099e9245e0 ("hfsplus: implement attributes file's
header node initialization code").
i_size_read() returns loff_t, which is long long, i.e. 64-bit. node_size
is size_t, which is either 32-bit or 64-bit. Hence
"i_size_read(attr_file) / node_size" is a 64-by-32 or 64-by-64 division,
causing (some versions of) gcc to emit a call to __divdi3().
Fortunately node_size is actually 16-bit, as the sole caller of
hfsplus_init_header_node() passes a u16. Hence change its type from
size_t to u16, and use do_div() to perform a 64-by-32 division.
Not seen in m68k/allmodconfig in -next, so it really depends on the
verion of gcc.

This patch enhances the type safety for the kfifo API. It is now safe
to put const data into a non const FIFO and the API will now generate a
compiler warning when reading from the fifo where the destination
address is pointing to a const variable.
As a side effect the kfifo_put() does now expect the value of an element
instead a pointer to the element. This was suggested Russell King. It
make the handling of the kfifo_put easier since there is no need to
create a helper variable for getting the address of a pointer or to pass
integers of different sizes.
IMHO the API break is okay, since there are currently only six users of
kfifo_put().
The code is also cleaner by kicking out the "if (0)" expressions.

'copied' and 'len' are in bytes, while 'ret' is in elements, so we need to
multiply 'ret' with the size of one element to get the correct result.

This commit was incomplete in that code to remove items from the per-cpu
lists was missing and never acquired a user in the 5 years it has been in
the tree. We're going to implement what it seems to try to archive in a
simpler way, and this code is in the way of doing so.
