8f84ab7859 powerpc: vdso: Make vdso32 installation conditional in vdso_install
[ Upstream commit ff6d27823f619892ab96f7461764840e0d786b15 ]

The 32-bit vDSO is not needed and not normally built for 64-bit
little-endian configurations.  However, the vdso_install target still
builds and installs it.  Add the same config condition as is normally
used for the build.

ab6276c251 tipc: set sysctl_tipc_rmem and named_timeout right range
[ Upstream commit 4bcd4ec1017205644a2697bccbc3b5143f522f5f ]

We find that sysctl_tipc_rmem and named_timeout do not have the right minimum
setting. sysctl_tipc_rmem should be larger than zero, like sysctl_tcp_rmem.
And named_timeout as a timeout setting should be not less than zero.

55865d61ed hwmon: (w83627hf) Use request_muxed_region for Super-IO accesses
[ Upstream commit e95fd518d05bfc087da6fcdea4900a57cfb083bd ]

Super-IO accesses may fail on a system with no or unmapped LPC bus.

Also, other drivers may attempt to access the LPC bus at the same time,
resulting in undefined behavior.

Use request_muxed_region() to ensure that IO access on the requested
address space is supported, and to ensure that access by multiple drivers
is synchronized.

d81311b357 spi: bcm2835aux: fix driver to not allow 65535 (=-1) cs-gpios
[ Upstream commit 509c583620e9053e43d611bf1614fc3d3abafa96 ]

The original driver by default defines num_chipselects as -1.
This actually allicates an array of 65535 entries in
of_spi_register_master.

There is a side-effect for buggy device trees that (contrary to
dt-binding documentation) have no cs-gpio defined.

This mode was never supported by the driver due to limitations
of native cs and additional code complexity and is explicitly
not stated to be implemented.

To keep backwards compatibility with such buggy DTs we limit
the number of chip_selects to 1, as for all practical purposes
it is only ever realistic to use a single chip select in
native cs mode without negative side-effects.

a56dd08167 spi: tegra114: fix for unpacked mode transfers
[ Upstream commit 1a89ac5b91895127f7c586ec5075c3753ca25501 ]

Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked
mode when transfer length is not a multiple of requested bits per word.

unpacked mode transfers fails when the transfer includes partial bytes in
the last word.

Total words to be written/read to/from FIFO is computed based on transfer
length and bits per word. Unpacked mode includes 0 padding bytes for partial
words to align with bits per word and these extra bytes are also accounted
for calculating bytes left to transfer in the current driver.

This causes extra bytes access of tx/rx buffers along with buffer index
position crossing actual length where remain_len becomes negative and due to
unsigned type, negative value is a 32 bit representation of signed value
and transferred bytes never meets the actual transfer length resulting in
transfer timeout and a hang.

This patch fixes this with proper computation of the actual bytes to fill in
FIFO during transmit and the actual bytes to read from FIFO during receive
ignoring 0 padded bytes.

f58b53315e media: davinci-isif: avoid uninitialized variable use
[ Upstream commit 0e633f97162c1c74c68e2eb20bbd9259dce87cd9 ]

clang warns about a possible variable use that gcc never
complained about:

drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here
      [-Werror,-Wuninitialized]
                dm365_vpss_set_pg_frame_size(frame_size);
                                             ^~~~~~~~~~
drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here
        struct vpss_pg_frame_size frame_size;
        ^
1 error generated.

There is no initialization for this variable at all, and there
has never been one in the mainline kernel, so we really should
not put that stack data into an mmio register.

On the other hand, I suspect that gcc checks the condition
more closely and notices that the global
isif_cfg.bayer.config_params.test_pat_gen flag is initialized
to zero and never written to from any code path, so anything
depending on it can be eliminated.

To shut up the clang warning, just remove the dead code manually,
it has probably never been used because any attempt to do so
would have resulted in undefined behavior.

d3263a55cb ARM: OMAP2+: Fix potentially uninitialized return value for _setup_reset()
[ Upstream commit 7f0d078667a494466991aa7133f49594f32ff6a2 ]

Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made
the call to _enable() conditional based on no oh->rst_lines_cnt. This
caused the return value to be potentially uninitialized. Curiously we see
no compiler warnings for this, probably as this gets inlined.

We call _setup_reset() from _setup() and only _setup_postsetup() if the
return value is zero. Currently the return value can be uninitialized for
cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

[ Upstream commit 31b6a05f86e690e1818116fd23c3be915cc9d9ed ]

megaraid_sas takes 1+ seconds to load while waiting for firmware:

[2.822603] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[3.871003] megaraid_sas 0000:03:00.0: FW now in Ready state

This is due to the following loop in megasas_transition_to_ready(), which
waits a minimum of 1 second, even though the FW becomes ready in tens of
millisecs:

        /*
         * The cur_state should not last for more than max_wait secs
         */
        for (i = 0; i < max_wait; i++) {
                ...
                msleep(1000);
        ...
        dev_info(&instance->pdev->dev, "FW now in Ready state\n");

This is a regression, caused by a change of the msleep granularity from 1
to 1000 due to concern about waiting too long on systems with coarse
jiffies.

To fix, increase iterations and use msleep(20), which results in:

[2.670627] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[2.739386] megaraid_sas 0000:03:00.0: FW now in Ready state

[ Upstream commit ca70ea43f80c98582f5ffbbd1e6f4da2742da0c4 ]

MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to
perform low-level platform initialization. This results in a try to install
HYP stubs for the second time for each CPU and results in false HYP/SVC
mode mismatch detection. The HYP stubs are already installed at the
beginning of the kernel initialization on the boot CPU (head.S) or in the
secondary_startup() for other CPUs. To fix this issue MCPM code should use
a cpu_resume() routine without HYP stubs installation.

This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid
XU3/XU4/HC1 boards.

983f90b9cc fs/nfs: Fix nfs_parse_devname to not modify it's argument
[ Upstream commit 40cc394be1aa18848b8757e03bd8ed23281f572e ]

In the rare and unsupported case of a hostname list nfs_parse_devname
will modify dev_name.  There is no need to modify dev_name as the all
that is being computed is the length of the hostname, so the computed
length can just be shorted.

[ Upstream commit 8d1667200850f8753c0265fa4bd25c9a6e5f94ce ]

The apq8016 driver leaves the of-node refcount at aborting from the
loop of for_each_child_of_node() in the error path.  Not only the
iterator node of for_each_child_of_node(), the children nodes referred
from it for codec and cpu have to be properly unreferenced.

c83057a12e drm/nouveau/bios/ramcfg: fix missing parentheses when calculating RON
[ Upstream commit 13649101a25c53c87f4ab98a076dfe61f3636ab1 ]

Currently, the expression for calculating RON is always going to result
in zero no matter the value of ram->mr[1] because the ! operator has
higher precedence than the shift >> operator.  I believe the missing
parentheses around the expression before appying the ! operator will
result in the desired result.

pci_map_rom/pci_get_rom_size() performs memory access in the ROM.
In case the Memory Space accesses were disabled, readw() is likely
to trigger a synchronous external abort on some platforms.

In case memory accesses were disabled, re-enable them before the
call and disable them back again just after.

[ Upstream commit 1a67356e9a4829da2935dd338630a550c59c8489 ]

It is wrong to use bio->bi_vcnt to figure out how many segments
there are in the bio even though CLONED flag isn't set on this bio,
because this bio may be splitted or advanced.

So always use bio_segments() in blk_recount_segments(), and it shouldn't
cause any performance loss now because the physical segment number is figured
out in blk_queue_split() and BIO_SEG_VALID is set meantime since
