Linus Torvalds 768fc661d1 RISC-V updates for v5.5-rc5
Several fixes for RISC-V:
 
 - Fix function graph trace support
 
 - Prefix the CSR IRQ_* macro names with "RV_", to avoid collisions
   with macros elsewhere in the Linux kernel tree named "IRQ_TIMER"
 
 - Use __pa_symbol() when computing the physical address of a kernel
   symbol, rather than __pa()
 
 - Mark the RISC-V port as supporting GCOV
 
 One DT addition:
 
 - Describe the L2 cache controller in the FU540 DT file
 
 One documentation update:
 
 - Add patch acceptance guideline documentation

Paul Walmsley 0e194d9da1 Documentation: riscv: add patch acceptance guidelines
Formalize, in kernel documentation, the patch acceptance policy for
arch/riscv.  In summary, it states that as maintainers, we plan to
only accept patches for new modules or extensions that have been
frozen or ratified by the RISC-V Foundation.

We've been following these guidelines for the past few months.  In the
meantime, we've received quite a bit of feedback that it would be
helpful to have these guidelines formally documented.

Based on a suggestion from Matthew Wilcox, we also add a link to this
file to Documentation/process/index.rst, to make this document easier
to find.  The format of this document has also been changed to align
to the format outlined in the maintainer entry profiles, in accordance
with comments from Jon Corbet and Dan Williams.

Andrey Konovalov a69b83e1ae kcov: fix struct layout for kcov_remote_arg
Make the layout of kcov_remote_arg the same for 32-bit and 64-bit code.
This makes it more convenient to write userspace apps that can be
compiled into 32-bit or 64-bit binaries and still work with the same
64-bit kernel.

Also use proper __u32 types in uapi headers instead of unsigned ints.

Masahiro Yamada 28f94a4429 kbuild: clarify the difference between obj-y and obj-m w.r.t. descending
Kbuild descends into a directory by either 'y' or 'm', but there is an
important difference.

Kbuild combines the built-in objects into built-in.a in each directory.
The built-in.a in the directory visited by obj-y is merged into the
built-in.a in the parent directory. This merge happens recursively
when Kbuild is ascending back towards the top directory, then built-in
objects are linked into vmlinux eventually. This works properly only
when the Makefile specifying obj-y is reachable by the chain of obj-y.

On the other hand, Kbuild does not take built-in.a from the directory
visited by obj-m. This it, all the objects in that directory are
supposed to be modular. If Kbuild descends into a directory by obj-m,
but the Makefile in the sub-directory specifies obj-y, those objects
are just left orphan.

The current statement "Kbuild only uses this information to decide that
it needs to visit the directory" is misleading. Clarify the difference.

This is a follow-up commit for the sysfs attributes to change
from DRIVER_ATTR to DEVICE_ATTR according to some initial comments.
In such case, it's better to point the sysfs path to the device
itself instead of the driver. The ABI document is also updated.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), scripts/checkpatch.pl warns the use of ---help---.

Kconfig still supports ---help---, but new code should avoid using it.
Let's stop advertising it in documentation.

Linus Torvalds ea200dec51 ARM: SoC fixes
I didn't get a batch in this weekend, so here's what we queued up last
 week and today.
 
  - A couple of defconfigs add back debugfs -- it used to be implicitly
  enabled through CONFIG_TRACING, but 0e4a459f56 ("tracing: Remove
  unnecessary DEBUG_FS dependency") removed that.
 
  - The rest are mostly minor fixlets of the usual kind; some DT tweaks,
  a headerfile refactor that needs a build fix now, etc.

Linus Torvalds 15da849c91 - Fix DM multipath by restoring full path selector functionality for
bio-based configurations that don't haave a SCSI device handler.
 
 - Fix dm-btree removal to ensure non-root btree nodes have at least
   (max_entries / 3) entries.  This resolves userspace thin_check
   utility's report of "too few entries in btree_node".
 
 - Fix both the DM thin-provisioning and dm-clone targets to properly
   flush the data device prior to metadata commit.  This resolves the
   potential for inconsistency across a power loss event when the data
   device has a volatile writeback cache.
 
 - Small documentation fixes to dm-clone and dm-integrity.

Merge tag 'sizeof_field-v5.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull FIELD_SIZEOF conversion from Kees Cook:
 "A mostly mechanical treewide conversion from FIELD_SIZEOF() to
  sizeof_field(). This avoids the redundancy of having 2 macros
  (actually 3) doing the same thing, and consolidates on sizeof_field().
  While "field" is not an accurate name, it is the common name used in
  the kernel, and doesn't result in any unintended innuendo.

  As there are still users of FIELD_SIZEOF() in -next, I will clean up
  those during this coming development cycle and send the final old
  macro removal patch at that time"

Marc Kleine-Budde says:

====================
pull-request: can 2019-12-08

this is a pull request of 13 patches for net/master.

The first two patches are by Dan Murphy. He adds himself as a maintainer to the
m-can MMIO and tcan SPI driver.

The next two patches the j1939 stack. The first one is by Oleksij Rempel and
fixes a locking problem found by the syzbot, the second one is by me an fixes a
mistake in the documentation.

Srinivas Neeli fixes missing RX CAN packets on CANFD2.0 in the xilinx driver.

Sean Nyekjaer fixes a possible deadlock in the the flexcan driver after
suspend/resume. Joakim Zhang contributes two patches for the flexcan driver
that fix problems with the low power enter/exit.

The next 4 patches all target the tcan part of the m_can driver. Sean Nyekjaer
adds the required delay after reset and fixes the device tree binding example.
Dan Murphy's patches make the wake-gpio optional.

In the last patch Xiaolong Huang fixes several kernel memory info leaks to the
USB device in the kvaser_usb_leaf driver.
