6427ae06e4 jfs: fix bogus variable self-initialization
[ Upstream commit a5fdd713d256887b5f012608701149fa939e5645 ]

A statement was originally added in 2006 to shut up a gcc warning,
now but now clang warns about it:

fs/jfs/jfs_txnmgr.c:1932:15: error: variable 'pxd' is uninitialized when used within its own initialization
      [-Werror,-Wuninitialized]
                pxd_t pxd = pxd;        /* truncated extent of xad */
                      ~~~   ^~~

Modern versions of gcc are fine without the silly assignment, so just
drop it. Tested with gcc-4.6 (released 2011), 4.7, 4.8, and 4.9.

7a00814a95 scsi: megaraid_sas: reduce module load time
[ 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

865c879793 ARM: 8847/1: pm: fix HYP/SVC mode mismatch when MCPM is used
[ 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.

return 0.

Make the init code for both clock events and clocksource check the
returned clock rate and fail gracefully if the result is 0, instead of
causing a divide by 0 exception later on.

In the rare and unsupported case of a hostname list nfs_parse_devname

[ 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.

[ 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

2ae344cd19 rtc: ds1672: fix unintended sign extension
[ Upstream commit f0c04c276739ed8acbb41b4868e942a55b128dca ]

Shifting a u8 by 24 will cause the value to be promoted to an integer. If
the top bit of the u8 is set then the following conversion to an unsigned
long will sign extend the value causing the upper 32 bits to be set in
the result.

Fix this by casting the u8 value to an unsigned long before the shift.

fb1778eb80 rtc: cmos: ignore bogus century byte
[ Upstream commit 2a4daadd4d3e507138f8937926e6a4df49c6bfdc ]

Older versions of Libreboot and Coreboot had an invalid value
(`3' in my case) in the century byte affecting the GM45 in
the Thinkpad X200.  Not everybody's updated their firmwares,
and Linux <= 4.2 was able to read the RTC without problems,
so workaround this by ignoring invalid values.

[ Upstream commit 19c624c6b29e244c418f8b44a711cbf5e82e3cd4 ]

This commit corrects max and step values for v4l2 control for
V4L2_CID_JPEG_RESTART_INTERVAL. Max should be 0xffff and step should be 1.
It was found by using v4l2-compliance tool and checking result of
VIDIOC_QUERY_EXT_CTRL/QUERYMENU test.
Previously it was complaining that step was bigger than difference
between max and min.

The IP10[5:3] field in Peripheral Function Select Register 10 has a
width of 3 bits, i.e. it allows programming one out of 8 different
configurations.
However, 9 values are provided instead of 8, overflowing into the
subsequent field in the register, and thus breaking the configuration of
the latter.

Fix this by dropping a bogus zero value.
