Commit b9f5fb1800 ("cramfs: fix MTD dependency") did what it says.
Since commit 9059a3493e ("kconfig: fix relational operators for bool
and tristate symbols") it is possible to do it slightly better though.

Spectre v1 mitigation:
- back-end version of array_index_mask_nospec()
- masking of the syscall number to restrict speculation through the
syscall table
- masking of __user pointers prior to deference in uaccess routines
Spectre v2 mitigation update:
- using the new firmware SMC calling convention specification update
- removing the current PSCI GET_VERSION firmware call mitigation as
vendors are deploying new SMCCC-capable firmware
- additional branch predictor hardening for synchronous exceptions and
interrupts while in user mode
Meltdown v3 mitigation update for Cavium Thunder X: unaffected but
hardware erratum gets in the way. The kernel now starts with the page
tables mapped as global and switches to non-global if kpti needs to be
enabled.
Other:
- Theoretical trylock bug fixed

CRIS: Restore mistakenly cleared kernel Makefile
Commit 0fbc0b67a8 ("cris: remove arch specific early DT functions")
was a bit overzealous in removing the CRIS DT handling,
and the complete contents of the Makefile was erased
instead of just the line for the devicetree file.
This lead to a complete link failure for all SoCs in
the CRIS port due to missing symbols.
Restore the contents except the line for the devicetree file.

With the merge window having been delayed for another week here's
another batch of updates that came in during that week. There's a few
important fixes in here, mainly a fix for I/O on a number of devices
caused by some of the component rework and a fix for a potential issue
if more than one component in a link provides compressed operations.
The I/O fixes are particularly important as the problem causes a power
regression on a number of OMAP platforms.

Pull more ASoC updates from Mark Brown:
"With the merge window having been delayed for another week here's
another batch of updates that came in during that week.
There's a few important fixes in here, mainly a fix for I/O on a
number of devices caused by some of the component rework and a fix for
a potential issue if more than one component in a link provides
compressed operations. The I/O fixes are particularly important as the
problem causes a power regression on a number of OMAP platforms"

This tag contains the fixes we'd like to target for the 4.16 merge
window. It's not as much as I was originally hoping to do but between
glibc, the chip, and FOSDEM there just wasn't enough time to get
everything put together. As such, this merge window is essentially just
going to be small changes. This includes mostly cleanups:
* A build fix failure to the audit test cases. RISC-V doesn't have
renameat because the generic syscall ABI moved to renameat2 by the
time of our port. The syscall audit test cases don't understand this,
so I added a trivial fix. This went through mailing list review
during the 4.15 merge window, but nobody has picked it up so I think
it's best to just do this here.
* The removal of our command-line argument processing code. The
"mem_end" stuff was broken and the rest duplicated generic device tree
code. The generic code was already being called.
* Some unused/redundant code has been removed, including
__ARCH_HAVE_MMU, current_pgdir, and the initialization of init_mm.pgd.
* SUM is disabled upon taking a trap, which means that user memory is
protected during traps taking inside copy_{to,from}_user().
* The sptbr CSR has been renamed to satp in C code. We haven't changed
the assembly code in order to maintain compatibility with binutils
2.29, which doesn't understand the new name.
Additionally, we're adding some new features:
* Basic ftrace support, thanks to Alan Kao!
* Support for ZONE_DMA32. This is necessary for all the normal reasons,
but also to deal with a deficiency in the Xilinx PCIe controller we're
using on our FPGA-based systems. While the ZONE_DMA32 addition should
be sufficient for most uses, it doesn't complete the fix for the
Xilinx controller.
* TLB shootdowns now only target the harts where they're necessary,
instead of applying to all harts in the system.
These patches have all been sitting on our linux-next branch for a while
now. Due to time constraints this is all I feel comfortable submitting
during the 4.16 merge window, hopefully we'll do better next time!

This driver used the wrong OF-helper when looking up the optional
capture-codec child node during probe. Instead of searching just
children of the sound node, a tree-wide depth-first search starting at
the unrelated platform node was done. Not only could this end up
matching an unrelated node or no node at all; the platform node could
also be prematurely freed since of_find_node_by_name() drops a reference
to its first argument. This particular pattern has been observed leading
to crashes after probe deferrals in other drivers.
Fix this by dropping the broken call to of_find_node_by_name() and
keeping only the second, correct lookup using of_get_child_by_name()
while taking care not to bail out if the optional node is missing.
Note that this also addresses two capture-codec node-reference leaks
(one for each of the original helper calls).
Compile tested only.

This fix a bug in dapm_widget_power_read_file(),
where it may sent opposite order of source/sink widget
into the p->connected().
for example,
static int connected_check(source, sink);
{"w_sink", NULL, "w_source", connected_check}
the dapm_widget_power_read_file() will query p->connected()
in following case
p->conneted("w_source", "w_sink")
p->conneted("w_sink", "w_source")
we should avoid the last case, since it's the wrong order (source/sink)

The pipe buffer limits are accessed without any locking, and may be
changed at any time by the sysctl handlers. In theory this could cause
problems for expressions like the following:
pipe_user_pages_hard && user_bufs > pipe_user_pages_hard
... since the assembly code might reference the 'pipe_user_pages_hard'
memory location multiple times, and if the admin removes the limit by
setting it to 0, there is a very brief window where processes could
incorrectly observe the limit to be exceeded.
Fix this by loading the limits with READ_ONCE() prior to use.

round_pipe_size() calculates the number of pages the requested size
corresponds to, then rounds the page count up to the next power of 2.
However, it also rounds everything < PAGE_SIZE up to PAGE_SIZE.
Therefore, there's no need to actually translate the size into a page
count; we just need to round the size up to the next power of 2.
We do need to verify the size isn't greater than (1 << 31), since on
32-bit systems roundup_pow_of_two() would be undefined in that case. But
that can just be combined with the UINT_MAX check which we need anyway
now.
Finally, update pipe_set_size() to not redundantly check the return value
of round_pipe_size() for the "invalid size" case twice.

A pipe's size is represented as an 'unsigned int'. As expected, writing a
value greater than UINT_MAX to /proc/sys/fs/pipe-max-size fails with
EINVAL. However, the F_SETPIPE_SZ fcntl silently truncates such values to
32 bits, rather than failing with EINVAL as expected. (It *does* fail
with EINVAL for values above (1 << 31) but <= UINT_MAX.)
Fix this by moving the check against UINT_MAX into round_pipe_size() which
is called in both cases.
