Wolfram Sang abe41184ab i2c: recovery: if possible send STOP with recovery pulses
I2C clients may misunderstand recovery pulses if they can't read SDA to
bail out early. In the worst case, as a write operation. To avoid that
and if we can write SDA, try to send STOP to avoid the
misinterpretation.

Paul Menzel 9feeb638cd tools build: fix # escaping in .cmd files for future Make
In 2016 GNU Make made a backwards incompatible change to the way '#'
characters were handled in Makefiles when used inside functions or
macros:

http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57

Due to this change, when attempting to run `make prepare' I get a
spurious make syntax error:

    /home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator.  Stop.

When inspecting `.fixdep.o.cmd' it includes two lines which use
unescaped comment characters at the top:

    \# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep)
    \# using basic dep data

This is because `tools/build/Build.include' prints these '\#'
characters:

    printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \
    printf '\# using basic dep data\n\n' >> $(dot-target).cmd;           \

This completes commit 9564a8cf42 ("Kbuild: fix # escaping in .cmd files
for future Make").

Call secure services to enable ACTLR[0] (Enable invalidates of BTB with
ICIALLU) when branch hardening is enabled for kernel.

On GP devices OMAP5/DRA7, there is no possibility to update secure
side since "secure world" is ROM and there are no override mechanisms
possible. On HS devices, appropriate PPA should do the workarounds as
well.

However, the configuration is only done for secondary core, since it is
expected that firmware/bootloader will have enabled the required
configuration for the primary boot core (note: bootloaders typically
will NOT enable secondary processors, since it has no need to do so).

In the error path of fsi_master_register(), we currently
use device_unregister(). This will cause the last reference
to the structure to be dropped, thus freeing the enclosing
structure, which isn't what the callers want.

Use device_del() instead so that we return to the caller
with a refcount of 1. The caller can then assume that it
must use put_device() after a call to fsi_master_register()
regardless of whether the latter suceeded or failed.

Chanwoo Choi 8a9dbb779f extcon: Release locking when sending the notification of connector state
Previously, extcon used the spinlock before calling the notifier_call_chain
to prevent the scheduled out of task and to prevent the notification delay.
When spinlock is locked for sending the notification, deadlock issue
occured on the side of extcon consumer device. To fix this issue,
extcon consumer device should always use the work. it is always not
reasonable to use work.

To fix this issue on extcon consumer device, release locking when sending
the notification of connector state.

Steven Rostedt (VMware) b4c7e2bd2e ARM: 8780/1: ftrace: Only set kernel memory back to read-only after boot
Dynamic ftrace requires modifying the code segments that are usually
set to read-only. To do this, a per arch function is called both before
and after the ftrace modifications are performed. The "before" function
will set kernel code text to read-write to allow for ftrace to make the
modifications, and the "after" function will set the kernel code text
back to "read-only" to keep the kernel code text protected.

The issue happens when dynamic ftrace is tested at boot up. The test is
done before the kernel code text has been set to read-only. But the
"before" and "after" calls are still performed. The "after" call will
change the kernel code text to read-only prematurely, and other boot
code that expects this code to be read-write will fail.

The solution is to add a variable that is set when the kernel code text
is expected to be converted to read-only, and make the ftrace "before"
and "after" calls do nothing if that variable is not yet set. This is
similar to the x86 solution from commit 1623963097 ("ftrace, x86:
make kernel text writable only for conversions").
