f3ff6fb5db kconfig: echo stdin to stdout if either is redirected 
If stdio is not tty, conf_askvalue() puts additional new line to
prevent prompts from being concatenated into a single line.  This
care is missing in conf_choice(), so a 'choice' prompt and the next
prompt are shown in the same line.

Move the code into xfgets() to cater to all cases.  To improve this
more, let's echo stdin to stdout.  This clarifies what keys were
input from stdio and the stdout looks like as if it were from tty.

I removed the isatty(2) check since stderr is unrelated here.

d2a04648a5 kconfig: remove check_stdin() 
Except silentoldconfig, valid_stdin is 1, so check_stdin() is no-op.

oldconfig and silentoldconfig work almost in the same way except that
the latter generates additional files under include/.  Both ask users
for input for new symbols.

I do not know why only silentoldconfig requires stdio be tty.

  $ rm -f .config; touch .config
  $ yes "" | make oldconfig > stdout
  $ rm -f .config; touch .config
  $ yes "" | make silentoldconfig > stdout
  make[1]: *** [silentoldconfig] Error 1
  make: *** [silentoldconfig] Error 2
  $ tail -n 4 stdout
  Console input/output is redirected. Run 'make oldconfig' to update configuration.

  scripts/kconfig/Makefile:40: recipe for target 'silentoldconfig' failed
  Makefile:507: recipe for target 'silentoldconfig' failed

Redirection is useful, for example, for testing where we want to give
particular key inputs from a test file, then check the result.

cd58a91def kconfig: remove 'config*' pattern from .gitignnore 
I could not figure out why this pattern should be ignored.
Checking commit 1e65174a33 ("Add some basic .gitignore files")
did not help.

Let's remove this pattern, then see if it is really needed.

4f208f3921 kconfig: show '?' prompt even if no help text is available 
'make config', 'make oldconfig', etc. always receive '?' as a valid
input and show useful information even if no help text is available.

------------------------>8------------------------
foo (FOO) [N/y] (NEW) ?

There is no help available for this option.
Symbol: FOO [=n]
Type  : bool
Prompt: foo
  Defined at Kconfig:1
------------------------>8------------------------

However, '?' is not shown in the prompt if its help text is missing.
Let's show '?' all the time so that the prompt and the behavior match.

cb67ab2cd2 kconfig: do not write choice values when their dependency becomes n 
"# CONFIG_... is not set" for choice values are wrongly written into
the .config file if they are once visible, then become invisible later.

  Test case
  ---------

---------------------------(Kconfig)----------------------------
config A
	bool "A"

choice
	prompt "Choice ?"
	depends on A

config CHOICE_B
	bool "Choice B"

config CHOICE_C
	bool "Choice C"

endchoice
----------------------------------------------------------------

---------------------------(.config)----------------------------
CONFIG_A=y
----------------------------------------------------------------

With the Kconfig and .config above,

  $ make config
  scripts/kconfig/conf  --oldaskconfig Kconfig
  *
  * Linux Kernel Configuration
  *
  A (A) [Y/n] n
  #
  # configuration written to .config
  #
  $ cat .config
  #
  # Automatically generated file; DO NOT EDIT.
  # Linux Kernel Configuration
  #
  # CONFIG_A is not set
  # CONFIG_CHOICE_B is not set
  # CONFIG_CHOICE_C is not set

Here,

  # CONFIG_CHOICE_B is not set
  # CONFIG_CHOICE_C is not set

should not be written into the .config file because their dependency
"depends on A" is unmet.

Currently, there is no code that clears SYMBOL_WRITE of choice values.

Clear SYMBOL_WRITE for all symbols in sym_calc_value(), then set it
again after calculating visibility.  To simplify the logic, set the
flag if they have non-n visibility, regardless of types, and regardless
of whether they are choice values or not.

0a5f417674 kbuild: clang: disable unused variable warnings only when constant 
Currently, GCC disables -Wunused-const-variable, but not
-Wunused-variable, so warns unused variables if they are
non-constant.

While, Clang does not warn unused variables at all regardless of
the const qualifier because -Wno-unused-const-variable is implied
by the stronger option -Wno-unused-variable.

Disable -Wunused-const-variable instead of -Wunused-variable so that
GCC and Clang work in the same way.

   - Resizeable BAR support
   - Multi-display sync support
   - Enable swapout for reserved BOs during allocation
   - S3 fixes on Raven

3879ae653a The core framework has a handful of patches this time around, mostly due 
to the clk rate protection support added by Jerome Brunet. This feature
 will allow consumers to lock in a certain rate on the output of a clk so
 that things like audio playback don't hear pops when the clk frequency
 changes due to shared parent clks changing rates. Currently the clk
 API doesn't guarantee the rate of a clk stays at the rate you request
 after clk_set_rate() is called, so this new API will allow drivers
 to express that requirement. Beyond this, the core got some debugfs
 pretty printing patches and a couple minor non-critical fixes.
 
 Looking outside of the core framework diff we have some new driver
 additions and the removal of a legacy TI clk driver. Both of these hit
 high in the dirstat. Also, the removal of the asm-generic/clkdev.h file
 causes small one-liners in all the architecture Kbuild files. Overall, the
 driver diff seems to be the normal stuff that comes all the time to
 fix little problems here and there and to support new hardware.

adbc128fa8 ARM: SoC platform updates for 4.16 
These are mostly minor bugfixes, cleanup and many defconfig updates to
 support added drivers. In particular OMAP and PXA keep cleaning up the
 legacy code base, as usual.
 
 Nvidia adds some more SoC support code for Tegra 186.
 
 For the first time on years, we are actually adding a non-DT platform for,
 the EP93xx based Liebherr controller BK3.1. It's a minor variation of
 the EP93xx reference design and in active use, while EP93xx apparently
 doesn't have enough new development to have any device tree support.

Linus Torvalds
ab486bc9a5 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk 
Pull printk updates from Petr Mladek:

 - Add a console_msg_format command line option:

     The value "default" keeps the old "[time stamp] text\n" format. The
     value "syslog" allows to see the syslog-like "<log
     level>[timestamp] text" format.

     This feature was requested by people doing regression tests, for
     example, 0day robot. They want to have both filtered and full logs
     at hands.

 - Reduce the risk of softlockup:

     Pass the console owner in a busy loop.

     This is a new approach to the old problem. It was first proposed by
     Steven Rostedt on Kernel Summit 2017. It marks a context in which
     the console_lock owner calls console drivers and could not sleep.
     On the other side, printk() callers could detect this state and use
     a busy wait instead of a simple console_trylock(). Finally, the
     console_lock owner checks if there is a busy waiter at the end of
     the special context and eventually passes the console_lock to the
     waiter.

     The hand-off works surprisingly well and helps in many situations.
     Well, there is still a possibility of the softlockup, for example,
     when the flood of messages stops and the last owner still has too
     much to flush.

     There is increasing number of people having problems with
     printk-related softlockups. We might eventually need to get better
     solution. Anyway, this looks like a good start and promising
     direction.

 - Do not allow to schedule in console_unlock() called from printk():

     This reverts an older controversial commit. The reschedule helped
     to avoid softlockups. But it also slowed down the console output.
     This patch is obsoleted by the new console waiter logic described
     above. In fact, the reschedule made the hand-off less effective.

 - Deprecate "%pf" and "%pF" format specifier:

     It was needed on ia64, ppc64 and parisc64 to dereference function
     descriptors and show the real function address. It is done
     transparently by "%ps" and "pS" format specifier now.

     Sergey Senozhatsky found that all the function descriptors were in
     a special elf section and could be easily detected.

 - Remove printk_symbol() API:

     It has been obsoleted by "%pS" format specifier, and this change
     helped to remove few continuous lines and a less intuitive old API.

 - Remove redundant memsets:

     Sergey removed unnecessary memset when processing printk.devkmsg
     command line option.

27529c891b Mostly clean ups and small fixes 
There's not much changes for the tracing system this release.
 Mostly small clean ups and fixes.
 
 The biggest change is to how bprintf works. bprintf is used by
 trace_printk() to just save the format and args of a printf call,
 and the formatting is done when the trace buffer is read. This is
 done to keep the formatting out of the fast path (this was recommended
 by you). The issue is when arguments are de-referenced.
 
 If a pointer is saved, and the format has something like "%*pbl",
 when the buffer is read, it will de-reference the argument then.
 The problem is if the data no longer exists. This can cause the
 kernel to oops.
 
 The fix for this was to make these de-reference pointes do
 the formatting at the time it is called (the fast path), as
 this guarantees that the data exists (and doesn't change later)

8e44e6600c Merge branch 'KASAN-read_word_at_a_time' 
Merge KASAN word-at-a-time fixups from Andrey Ryabinin.

The word-at-a-time optimizations have caused headaches for KASAN, since
the whole point is that we access byte streams in bigger chunks, and
KASAN can be unhappy about the potential extra access at the end of the
string.

We used to have a horrible hack in dcache, and then people got
complaints from the strscpy() case.  This fixes it all up properly, by
adding an explicit helper for the "access byte stream one word at a
time" case.

* emailed patches from Andrey Ryabinin <aryabinin@virtuozzo.com>:
  fs: dcache: Revert "manually unpoison dname after allocation to shut up kasan's reports"
  fs/dcache: Use read_word_at_a_time() in dentry_string_cmp()

babcbbc7c4 fs: dcache: Revert "manually unpoison dname after allocation to shut up kasan's reports" 
This reverts commit df4c0e36f1.

It's no longer needed since dentry_string_cmp() now uses
read_word_at_a_time() to avoid kasan's reports.

bfe7aa6c39 fs/dcache: Use read_word_at_a_time() in dentry_string_cmp() 
dentry_string_cmp() performs the word-at-a-time reads from 'cs' and may
read slightly more than it was requested in kmallac().  Normally this
would make KASAN to report out-of-bounds access, but this was
workarounded by commit df4c0e36f1 ("fs: dcache: manually unpoison
dname after allocation to shut up kasan's reports").

This workaround is not perfect, since it allows out-of-bounds access to
dentry's name for all the code, not just in dentry_string_cmp().

So it would be better to use read_word_at_a_time() instead and revert
commit df4c0e36f1.

1a3241ff10 lib/strscpy: Shut up KASAN false-positives in strscpy() 
strscpy() performs the word-at-a-time optimistic reads.  So it may may
access the memory past the end of the object, which is perfectly fine
since strscpy() doesn't use that (past-the-end) data and makes sure the
optimistic read won't cross a page boundary.

Use new read_word_at_a_time() to shut up the KASAN.

Note that this potentially could hide some bugs.  In example bellow,
stscpy() will copy more than we should (1-3 extra uninitialized bytes):

        char dst[8];
        char *src;

        src = kmalloc(5, GFP_KERNEL);
        memset(src, 0xff, 5);
        strscpy(dst, src, 8);

7f1e541fc8 compiler.h: Add read_word_at_a_time() function. 
Sometimes we know that it's safe to do potentially out-of-bounds access
because we know it won't cross a page boundary.  Still, KASAN will
report this as a bug.

Add read_word_at_a_time() function which is supposed to be used in such
cases.  In read_word_at_a_time() KASAN performs relaxed check - only the
first byte of access is validated.

562f36ed28 Kconfig updates for v4.16 
A pretty big batch of Kconfig updates. I have to mention the lexer
 and parser of Kconfig are now built from real .l and .y sources.
 So, flex and bison are the requirement for building the kernel.
 Both of them (unlike gperf) have been stable for a long time. This
 change has been tested several weeks in linux-next, and I did not
 receive any problem report about this.
 
 Summary:
 
 - Add checks for mistakes, like the choice default is not in
   choice, help is doubled
 
 - Document data structure and complex code
 
 - Fix various memory leaks
 
 - Change Makefile to build lexer and parser instead of using
   pre-generated C files
 
 - Drop 'boolean' keyword, which is equivalent to 'bool'
 
 - Use default 'yy' prefix and remove unneeded Make variables
 
 - Fix gettext() check for xconfig
 
 - Announce that oldnoconfig will be finally removed
 
 - Make 'Selected by:' and 'Implied by' readable in help and
   search result
 
 - Hide silentoldconfig from 'make help' to stop confusing people
 
 - Fix misc things and cleanups

f6cff79f1d Char/Misc driver patches for 4.16-rc1 
Here is the big pull request for char/misc drivers for 4.16-rc1.
 
 There's a lot of stuff in here.  Three new driver subsystems were added
 for various types of hardware busses:
 	- siox
 	- slimbus
 	- soundwire
 as well as a new vboxguest subsystem for the VirtualBox hypervisor
 drivers.
 
 There's also big updates from the FPGA subsystem, lots of Android binder
 fixes, the usual handful of hyper-v updates, and lots of other smaller
 driver updates.
 
 All of these have been in linux-next for a long time, with no reported
 issues.

47fcc0360c Driver Core updates for 4.16-rc1 
Here is the set of "big" driver core patches for 4.16-rc1.
 
 The majority of the work here is in the firmware subsystem, with reworks
 to try to attempt to make the code easier to handle in the long run, but
 no functional change.  There's also some tree-wide sysfs attribute
 fixups with lots of acks from the various subsystem maintainers, as well
 as a handful of other normal fixes and changes.
 
 And finally, some license cleanups for the driver core and sysfs code.
 
 All have been in linux-next for a while with no reported issues.

5d8515bc23 Staging/IIO patches for 4.16-rc1 
Here is the big Staging and IIO driver patches for 4.16-rc1.
 
 There is the normal amount of new IIO drivers added, like all releases.
 
 The networking IPX and the ncpfs filesystem are moved into the staging
 tree, as they are on their way out of the kernel due to lack of use
 anymore.
 
 The visorbus subsystem finall has started moving out of the staging tree
 to the "real" part of the kernel, and the most and fsl-mc codebases are
 almost ready to move out, that will probably happen for 4.17-rc1 if all
 goes well.
 
 Other than that, there is a bunch of license header cleanups in the
 tree, along with the normal amount of coding style churn that we all
 know and love for this codebase.  I also got frustrated at the
 Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
 huge chunks of it that were never even being used.
 
 Full details of everything is in the shortlog.
 
 All of these patches have been in linux-next for a while with no
 reported issues.
