(commit 10d8713429d345867fc8998d6193b233c0cab28c upstream)
Mixing asm and C code is not recommended in a naked function by
gcc and leads to an error when using clang:
drivers/bus/arm-cci.c:2107:2: error: non-ASM statement in naked
function is not supported
unreachable();
^While the function is marked __naked it actually properly return
in asm. There is no need for the unreachable() call.GCC 7.2 generates identical object files before and after, other
than (for obvious reasons) the line numbers generated by
WANT_WARN_ON_SLOWPATH for all the WARN()s appearing later in the
file.Suggested-by: Russell King

[ Upstream commit 1898eb61fbc9703efee886d3abec27a388cf28c3 ]
The ARM CCN PMU driver uses dev_warn() to complain about parameters in
the user-provided perf_event_attr. This means that under normal
operation (e.g. a single invocation of the perf tool), a number of
messages warnings may be logged to dmesg.Tools may issue multiple syscalls to probe for feature support, and
multiple applications (from multiple users) can attempt to open events
simultaneously, so this is not very helpful, even if a user happens to
have access to dmesg. Worse, this can push important information out of
the dmesg ring buffer, and can significantly slow down syscall fuzzers,
vastly increasing the time it takes to find critical bugs.Demote the dev_warn() instances to dev_dbg(), as is the case for all
other PMU drivers under drivers/perf/. Users who wish to debug PMU event
initialisation can enable dynamic debug to receive these messages.Signed-off-by: Mark Rutland

commit e2bf801ecd4e62222a46d1ba9e57e710171d29c1 upstream.
Include the OF-based modalias in the uevent sent when registering devices
on the sunxi RSB bus, so that user space has a chance to autoload the
kernel module for the device.Fixes a regression caused by commit 3f241bfa60bd ("arm64: allwinner: a64:
pine64: Use dcdc1 regulator for mmc0"). When the axp20x-rsb module for
the AXP803 PMIC is built as a module, it is not loaded and the system

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

At least the Armada XP SoC supports 4GB on a single DRAM window. Because
the size register values contain the actual size - 1, the MSB is set in
that case. For example, the SDRAM window's control register's value is
0xffffffe1 for 4GB (bits 31 to 24 contain the size).The MBUS driver reads back each window's size from registers and
calculates the actual size as (control_reg | ~DDR_SIZE_MASK) + 1, which
overflows for 32 bit values, resulting in other miscalculations further
on (a bad RAM window for the CESA crypto engine calculated by
mvebu_mbus_setup_cpu_target_nooverlap() in my case).This patch changes the type in 'struct mbus_dram_window' from u32 to
u64, which allows us to keep using the same register calculation code in
most MBUS-using drivers (which calculate ->size - 1 again).Fixes: fddddb52a6c4 ("bus: introduce an Marvell EBU MBus driver")

If the driver is built as a module, autoload won't work because the module

The GISB bus can support addresses beyond 32-bits. So this commit
corrects support for reading a captured 64-bit address into a 64-bit
variable by obtaining the high bits from the ARB_ERR_CAP_HI_ADDR
register (when present) and then outputting the full 64-bit value.It also removes unused definitions.

When the state names got added a script was used to add the extra argument
to the calls. The script basically converted the state constant to a
string, but the cleanup to convert these strings into meaningful ones did
not happen.Replace all the useless strings with 'subsys/xxx/yyy:state' strings which
are used in all the other places already.Signed-off-by: Thomas Gleixner
