Pull more powerpc updates from Michael Ellerman:
"Here's some more updates for powerpc for 3.18.
They are a bit late I know, though must are actually bug fixes. In my
defence I nearly cut the top of my finger off last weekend in a
gruesome bike maintenance accident, so I spent a good part of the week
waiting around for doctors. True story, I can send photos if you like :)
Probably the most interesting fix is the sys_call_table one, which
enables syscall tracing for powerpc. There's a fix for HMI handling
for old firmware, more endian fixes for firmware interfaces, more EEH
fixes, Anton fixed our routine that gets the current stack pointer,
and a few other misc bits"

When posting a patch series that includes both code implementing a
Device Tree binding and its associated documentation, the DT docs
should come in the series before the implementation.
This not only avoids checkpatch.pl to complain about undocumented
bindings but also makes the review process easier.
Document this convention since it may not be obvious.

"A second (and last) round of late coming fixes and changes, almost all
of them in perf tooling:
User visible tooling changes:
- Add period data column and make it default in 'perf script' (Jiri
Olsa)
- Add a visual cue for toggle zeroing of samples in 'perf top'
(Taeung Song)
- Improve callchains when using libunwind (Namhyung Kim)
Tooling fixes and infrastructure changes:

command line combo (Yasser Shalabi)
- Fix off-by-one bugs in map->end handling (Stephane Eranian)
- Fix off-by-one bug in maps__find(), also related to map->end
handling (Namhyung Kim)
- Make struct symbol->end be the first addr after the symbol range,
to make it match the convention used for struct map->end. (Arnaldo
Carvalho de Melo)
- Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
live' (Jiri Olsa)
- Fix python test build by moving callchain_param to an object linked
into the python binding (Jiri Olsa)
- Document sysfs events/ interfaces (Cody P Schafer)
- Fix typos in perf/Documentation (Masanari Iida)
- Add missing 'struct option' forward declaration (Arnaldo Carvalho
de Melo)
- Add option to copy events when queuing for sorting across cpu
buffers and enable it for 'perf kvm stat live', to avoid having
events left in the queue pointing to the ring buffer be rewritten
in high volume sessions. (Alexander Yarygin, improving work done
by David Ahern):
- Do not include a struct hists per perf_evsel, untangling the
histogram code from perf_evsel, to pave the way for exporting a
minimalistic tools/lib/api/perf/ library usable by tools/perf and
initially by the rasd daemon being developed by Borislav Petkov,
Robert Richter and Jean Pihet. (Arnaldo Carvalho de Melo)
- Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
thread maps mean syswide monitoring, reducing the boilerplate for
tools that only want system wide mode. (Arnaldo Carvalho de Melo)
- Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
should be just a front end for exit + free (Arnaldo Carvalho de
Melo)
- Add support to new style format of kernel PMU event. (Kan Liang)
and other misc fixes"

Pull core block layer changes from Jens Axboe:
"This is the core block IO pull request for 3.18. Apart from the new
and improved flush machinery for blk-mq, this is all mostly bug fixes
and cleanups.
- blk-mq timeout updates and fixes from Christoph.
- Removal of REQ_END, also from Christoph. We pass it through the
->queue_rq() hook for blk-mq instead, freeing up one of the request
bits. The space was overly tight on 32-bit, so Martin also killed
REQ_KERNEL since it's no longer used.
- blk integrity updates and fixes from Martin and Gu Zheng.
- Update to the flush machinery for blk-mq from Ming Lei. Now we
have a per hardware context flush request, which both cleans up the
code should scale better for flush intensive workloads on blk-mq.
- Improve the error printing, from Rob Elliott.
- Backing device improvements and cleanups from Tejun.
- Fixup of a misplaced rq_complete() tracepoint from Hannes.
- Make blk_get_request() return error pointers, fixing up issues
where we NULL deref when a device goes bad or missing. From Joe
Lawrence.
- Prep work for drastically reducing the memory consumption of dm
devices from Junichi Nomura. This allows creating clone bio sets
without preallocating a lot of memory.
- Fix a blk-mq hang on certain combinations of queue depths and
hardware queues from me.
- Limit memory consumption for blk-mq devices for crash dump
scenarios and drivers that use crazy high depths (certain SCSI
shared tag setups). We now just use a single queue and limited
depth for that"

Pull clock tree updates from Mike Turquette:
"The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers.
This tag contains a bit more arch code than I usually take due to some
OMAP2+ changes. Additionally it contains the restart notifier
handlers which are merged as a dependency into several trees.
The PXA changes are the only messy part. Due to having a stable tree
I had to revert one patch and follow up with one more fix near the tip
of this tag. Some dead code is introduced but it will soon become
live code after 3.18-rc1 is released as the rest of the PXA family is
converted over to the common clock framework.
Another trend in this tag is that multiple vendors have started to
push the complexity of changing their CPU frequency into the clock
driver, whereas this used to be done in CPUfreq drivers.
Changes to the clk core include a generic gpio-clock type and a
clk_set_phase() function added to the top-level clk.h api. Due to
some confusion on the fbdev mailing list the kernel boot parameters
documentation was updated to further explain the clk_ignore_unused
parameter, which is often required by users of the simplefb driver.
Finally some fixes to the locking around the clock debugfs stuff was
done to prevent deadlocks when interacting with other subsystems."

This patch is to review the whole glue logic adopted on STi SoCs that
was bugged.
In the old glue-logic there was a lot of confusion when setup the
retiming especially for STiD127 where, for example, the bits 6 and 7
(in the GMAC control register) have a different meaning of what is
used for STiH4xx SoCs. So we cannot adopt the same glue for all these
SoCs.
Moreover, GiGa on STiD127 didn't work and, for all the SoCs, the RGMII
couldn't run when the speed was 10Mbps (because the clock was not properly
managed).
Note that the phy clock needs to be provided by the platform as well as
documented in the related binding file (updated as consequence).
The old code supported too many configurations never adopted and validated.
This made the code very complex to maintain and debug in case of issues.
The patch simplifies all the configurations as commented in the tables
inside the file and obviously it has been tested on all the boards
based on the SoCs mentioned.
With this patch, the dwmac-sti is also ready to support new configurations that
will be available on next SoC generations.

"This patch set contains the main portion of the changes for 3.18 in
regard to the s390 architecture. It is a bit bigger than usual,
mainly because of a new driver and the vector extension patches.
The interesting bits are:
- Quite a bit of work on the tracing front. Uprobes is enabled and
the ftrace code is reworked to get some of the lost performance
back if CONFIG_FTRACE is enabled.
- To improve boot time with CONFIG_DEBIG_PAGEALLOC, support for the
IPTE range facility is added.
- The rwlock code is re-factored to improve writer fairness and to be
able to use the interlocked-access instructions.
- The kernel part for the support of the vector extension is added.
- The device driver to access the CD/DVD on the HMC is added, this
will hopefully come in handy to improve the installation process.
- Add support for control-unit initiated reconfiguration.
- The crypto device driver is enhanced to enable the additional AP
domains and to allow the new crypto hardware to be used.

This allows user to print a given buffer as an escaped string. The
rules are applied according to an optional mix of flags provided by
additional format letters.
For example, if the given buffer is:
1b 62 20 5c 43 07 22 90 0d 5d
The result strings would be:
%*pE "\eb \C\a"\220\r]"
%*pEhp "\x1bb \C\x07"\x90\x0d]"
%*pEa "\e\142\040\\\103\a\042\220\r\135"

format_corename() can only pass the leader's pid to the core handler,
but there is no simple way to figure out which thread originated the
coredump.
As Jan explains, this also means that there is no simple way to create
the backtrace of the crashed process:
As programs are mostly compiled with implicit gcc -fomit-frame-pointer
one needs program's .eh_frame section (equivalently PT_GNU_EH_FRAME
segment) or .debug_frame section. .debug_frame usually is present only
in separate debug info files usually not even installed on the system.
While .eh_frame is a part of the executable/library (and it is even
always mapped for C++ exceptions unwinding) it no longer has to be
present anywhere on the disk as the program could be upgraded in the
meantime and the running instance has its executable file already
unlinked from disk.
One possibility is to echo 0x3f >/proc/*/coredump_filter and dump all
the file-backed memory including the executable's .eh_frame section.
But that can create huge core files, for example even due to mmapped
data files.
Other possibility would be to read .eh_frame from /proc/PID/mem at the
core_pattern handler time of the core dump. For the backtrace one needs
to read the register state first which can be done from core_pattern
handler:
ptrace(PTRACE_SEIZE, tid, 0, PTRACE_O_TRACEEXIT)
close(0); // close pipe fd to resume the sleeping dumper
waitpid(); // should report EXIT
PTRACE_GETREGS or other requests
The remaining problem is how to get the 'tid' value of the crashed
thread. It could be read from the first NT_PRSTATUS note of the core
file but that makes the core_pattern handler complicated.
Unfortunately %t is already used so this patch uses %i/%I.
Automatic Bug Reporting Tool (https://github.com/abrt/abrt/wiki/overview)
is experimenting with this. It is using the elfutils
(https://fedorahosted.org/elfutils/) unwinder for generating the
backtraces. Apart from not needing matching executables as mentioned
above, another advantage is that we can get the backtrace without saving
the core (which might be quite large) to disk.

This documents autofs from the perspective of what the module actually
supports rather than how automount is expected to use it.
It is formatted using "markdown" and works best with Markdown.pl
(markdown_py doesn't like some constructs).

The current code places a 256 byte limit on the registration format.
This ends up being fairly limited when you try to do matching against a
binary format like ELF:
- the magic & mask formats cannot have any embedded NUL chars
(string_unescape_inplace halts at the first NUL)
- each escape sequence quadruples the size: \x00 is needed for NUL
- trying to match bytes at the start of the file as well as further
on leads to a lot of \x00 sequences in the mask
- magic & mask have to be the same length (when decoded)
- still need bytes for the other fields
- impossible!
Let's look at a concrete (and common) example: using QEMU to run MIPS
ELFs. The name field uses 11 bytes "qemu-mipsel". The interp uses 20
bytes "/usr/bin/qemu-mipsel". The type & flags takes up 4 bytes. We
need 7 bytes for the delimiter (usually ":"). We can skip offset. So
already we're down to 107 bytes to use with the magic/mask instead of
the real limit of 128 (BINPRM_BUF_SIZE). If people use shell code to
register (which they do the majority of the time), they're down to ~26
possible bytes since the escape sequence must be \x##.
The ELF format looks like (both 32 & 64 bit):
e_ident: 16 bytes
e_type: 2 bytes
e_machine: 2 bytes
Those 20 bytes are enough for most architectures because they have so few
formats in the first place, thus they can be uniquely identified. That
also means for shell users, since 20 is smaller than 26, they can sanely
register a handler.
But for some targets (like MIPS), we need to poke further. The ELF fields
continue on:
e_entry: 4 or 8 bytes
e_phoff: 4 or 8 bytes
e_shoff: 4 or 8 bytes
e_flags: 4 bytes
We only care about e_flags here as that includes the bits to identify
whether the ELF is O32/N32/N64. But now we have to consume another 16
bytes (for 32 bit ELFs) or 28 bytes (for 64 bit ELFs) just to match the
flags. If every byte is escaped, we send 288 more bytes to the kernel
((20 {e_ident,e_type,e_machine} + 12 {e_entry,e_phoff,e_shoff} + 4
{e_flags}) * 2 {mask,magic} * 4 {escape}) and we've clearly blown our
budget.
Even if we try to be clever and do the decoding ourselves (rather than
relying on the kernel to process \x##), we still can't hit the mark --
string_unescape_inplace treats mask & magic as C strings so NUL cannot
be embedded. That leaves us with having to pass \x00 for the 12/24
entry/phoff/shoff bytes (as those will be completely random addresses),
and that is a minimum requirement of 48/96 bytes for the mask alone.
Add up the rest and we blow through it (this is for 64 bit ELFs):
magic: 20 {e_ident,e_type,e_machine} + 24 {e_entry,e_phoff,e_shoff} +
4 {e_flags} = 48 # ^^ See note below.
mask: 20 {e_ident,e_type,e_machine} + 96 {e_entry,e_phoff,e_shoff} +
4 {e_flags} = 120
Remember above we had 107 left over, and now we're at 168. This is of
course the *best* case scenario -- you'll also want to have NUL bytes
in the magic & mask too to match literal zeros.
Note: the reason we can use 24 in the magic is that we can work off of the
fact that for bytes the mask would clobber, we can stuff any value into
magic that we want. So when mask is \x00, we don't need the magic to also
be \x00, it can be an unescaped raw byte like '!'. This lets us handle
more formats (barely) under the current 256 limit, but that's a pretty
tall hoop to force people to jump through.
With all that said, let's bump the limit from 256 bytes to 1920. This way
we support escaping every byte of the mask & magic field (which is 1024
bytes by themselves -- 128 * 4 * 2), and we leave plenty of room for other
fields. Like long paths to the interpreter (when you have source in your
/really/long/homedir/qemu/foo). Since the current code stuffs more than
one structure into the same buffer, we leave a bit of space to easily
round up to 2k. 1920 is just as arbitrary as 256 ;).
