[PATCH AUTOSEL 4.4 1/8] ARC: build: add boot_targets to PHONY

[PATCH AUTOSEL 4.4 1/8] ARC: build: add boot_targets to PHONY

[Sasha Levin]

From: Masahiro Yamada <masahiroy@kernel.org>

[ Upstream commit 0cfccb3c04934cdef42ae26042139f16e805b5f7 ]

The top-level boot_targets (uImage and uImage.*) should be phony
targets. They just let Kbuild descend into arch/arc/boot/ and create
files there.

If a file exists in the top directory with the same name, the boot
image will not be created.

You can confirm it by the following steps:

  $ export CROSS_COMPILE=<your-arc-compiler-prefix>
  $ make -s ARCH=arc defconfig all   # vmlinux will be built
  $ touch uImage.gz
  $ make ARCH=arc uImage.gz
  CALL    scripts/atomic/check-atomics.sh
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  # arch/arc/boot/uImage.gz is not created

Specify the targets as PHONY to fix this.

[PATCH AUTOSEL 4.4 2/8] ethernet: ucc_geth: fix definition and size of ucc_geth_tx_global_pram

[Sasha Levin]

From: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

[ Upstream commit 887078de2a23689e29d6fa1b75d7cbc544c280be ]

Table 8-53 in the QUICC Engine Reference manual shows definitions of
fields up to a size of 192 bytes, not just 128. But in table 8-111,
one does find the text

  Base Address of the Global Transmitter Parameter RAM Page. [...]
  The user needs to allocate 128 bytes for this page. The address must
  be aligned to the page size.

I've checked both rev. 7 (11/2015) and rev. 9 (05/2018) of the manual;
they both have this inconsistency (and the table numbers are the
same).

Adding a bit of debug printing, on my board the struct
ucc_geth_tx_global_pram is allocated at offset 0x880, while
the (opaque) ucc_geth_thread_data_tx gets allocated immediately
afterwards, at 0x900. So whatever the engine writes into the thread
data overlaps with the tail of the global tx pram (and devmem says
that something does get written during a simple ping).

I haven't observed any failure that could be attributed to this, but
it seems to be the kind of thing that would be extremely hard to
debug. So extend the struct definition so that we do allocate 192
bytes.

[PATCH AUTOSEL 4.4 3/8] CDC-NCM: remove "connected" log message

[Sasha Levin]

From: Roland Dreier <roland@kernel.org>

[ Upstream commit 59b4a8fa27f5a895582ada1ae5034af7c94a57b5 ]

The cdc_ncm driver passes network connection notifications up to
usbnet_link_change(), which is the right place for any logging.
Remove the netdev_info() duplicating this from the driver itself.

This stops devices such as my "TRENDnet USB 10/100/1G/2.5G LAN"
(ID 20f4:e02b) adapter from spamming the kernel log with

    cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected

messages every 60 msec or so.

[PATCH AUTOSEL 4.4 4/8] arch/arc: add copy_user_page() to <asm/page.h> to fix build error on ARC

[ Upstream commit ee61cfd955a64a58ed35cbcfc54068fcbd486945 ]

It adds a stub acpi_create_platform_device() for !CONFIG_ACPI build, so
that caller doesn't have to deal with !CONFIG_ACPI build issue.

[PATCH AUTOSEL 4.4 8/8] ARM: picoxcell: fix missing interrupt-parent properties

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit bac717171971176b78c72d15a8b6961764ab197f ]

dtc points out that the interrupts for some devices are not parsable:

picoxcell-pc3x2.dtsi:45.19-49.5: Warning (interrupts_property): /paxi/gem@30000: Missing interrupt-parent
picoxcell-pc3x2.dtsi:51.21-55.5: Warning (interrupts_property): /paxi/dmac@40000: Missing interrupt-parent
picoxcell-pc3x2.dtsi:57.21-61.5: Warning (interrupts_property): /paxi/dmac@50000: Missing interrupt-parent
picoxcell-pc3x2.dtsi:233.21-237.5: Warning (interrupts_property): /rwid-axi/axi2pico@c0000000: Missing interrupt-parent

There are two VIC instances, so it's not clear which one needs to be
used. I found the BSP sources that reference VIC0, so use that:
