The new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING has been added
to indicate that Relaxed Ordering Attributes (RO) should not
be used for Transaction Layer Packets (TLP) targeted toward
these affected Root Port, it will clear the bit4 in the PCIe
Device Control register, so the PCIe device drivers could
query PCIe configuration space to determine if it can send
TLPs to Root Port with the Relaxed Ordering Attributes set.
With this new flag we don't need the config ARCH_WANT_RELAX_ORDER
to control the Relaxed Ordering Attributes for the ixgbe drivers
just like the commit 1a8b6d76dc5b ("net:add one common config...") did,
so revert this commit.

The FPU emulator includes 2 calls to pr_err() which are triggered by
invalid instruction encodings for MIPSr6 cmp.cond.fmt instructions.
These cases are not kernel errors, merely invalid instructions which are
already handled by delivering a SIGILL which will provide notification
that something failed in cases where that makes sense.
In cases where that SIGILL is somewhat expected & being handled, for
example when crashme happens to generate one of the affected bad
encodings, the message is printed with no useful context about what
triggered it & spams the kernel log for no good reason.
Remove the pr_err() calls to make crashme run silently & treat the bad
encodings the same way we do others, with a SIGILL & no further kernel
log output.

When configuring the kernel using one of the generic MIPS defconfig
targets, the generic-board-config.sh script is used to check
requirements listed in board config fragments against a reference config
in order to determine which board config fragments to merge into the
final config.
When specifying O= to configure in a directory other than the kernel
source directory, this generic-board-config.sh script is invoked in the
directory that we are configuring in (ie. the directory that O equals),
and the path to the reference config is relative to the current
directory. The script then changes the current directory to the source
tree, which unfortunately breaks later access to the reference file
since its path is relative to a directory that is no longer the current
working directory. This results in configuration failing with errors
such as:
$ make ARCH=mips O=tmp 32r2_defconfig
make[1]: Entering directory '/home/pburton/src/linux/tmp'
Using ../arch/mips/configs/generic_defconfig as base

make[1]: Leaving directory '/home/pburton/src/linux-ingenic/tmp'

Fix this by avoiding changing the working directory in
generic-board-config.sh, instead using full paths to files under
$(srctree)/ where necessary.

Commit 8263db4d7768 ("MIPS: cmpxchg: Implement __cmpxchg() as a
function") refactored our implementation of __cmpxchg() to be a function
rather than a macro, with the aim of making it easier to read & modify.
Unfortunately the commit breaks use of cmpxchg() for signed 32 bit
values when we have a 64 bit kernel with kernel_uses_llsc == false,
because:
- In cmpxchg_local() we cast the old value to the type the pointer
points to, and then to an unsigned long. If the pointer points to a
signed type smaller than 64 bits then the old value will be sign
extended to 64 bits. That is, bits beyond the size of the pointed to
type will be set to 1 if the old value is negative. In the case of a
signed 32 bit integer with a negative value, bits 63:32 will all be
set.
- In __cmpxchg_asm() we load the value from memory, ie. dereference the
pointer, and store the value as an unsigned integer (__ret) whose
size matches the pointer. For a 32 bit cmpxchg() this means we store
the value in a u32, because the pointer provided to __cmpxchg_asm()
by __cmpxchg() is of type volatile u32 *.
- __cmpxchg_asm() then checks whether the value in memory (__ret)
matches the provided old value, by comparing the two values. This
results in the u32 being promoted to a 64 bit unsigned long to match
the old argument - however because both types are unsigned the value
is zero extended, which does not match the sign extension performed
on the old value in cmpxchg_local() earlier.
This mismatch means that unfortunate cmpxchg() calls can incorrectly
fail for 64 bit kernels with kernel_uses_llsc == false. This is the case
on at least non-SMP Cavium Octeon kernels, which hardcode
kernel_uses_llsc in their cpu-feature-overrides.h header. Using a
v4.13-rc7 kernel configured using cavium_octeon_defconfig with SMP
manually disabled, this presents itself as oddity when we reach
userland - for example:
can't run '/bin/mount': Text file busy
can't run '/bin/mkdir': Text file busy
can't run '/bin/mkdir': Text file busy
can't run '/bin/mount': Text file busy
can't run '/bin/hostname': Text file busy
can't run '/etc/init.d/rcS': Text file busy
can't run '/sbin/getty': Text file busy
can't run '/sbin/getty': Text file busy
It appears that some part of the init process, which is in this case
buildroot's busybox init, is running successfully. It never manages to
reach the login prompt though, and complains about /sbin/getty being
busy repeatedly and indefinitely.
Fix this by casting the old value provided to __cmpxchg_asm() to an
appropriately sized unsigned integer, such that we consistently
zero-extend avoiding the mismatch. The __cmpxchg_small() case for 8 & 16
bit values is unaffected because __cmpxchg_small() already masks
provided values appropriately.

Compiling ebpf_jit.c with gcc 4.9 results in a (likely spurious)
compiler warning, as gcc has detected that the variable "target" may be
used uninitialised. Since -Werror is active, this is treated as an error
and causes a kernel build failure whenever CONFIG_MIPS_EBPF_JIT is
enabled.

The alt_max_short() macro in asm/alternative.h does not work as
intended, leading to nasty bugs. E.g. alt_max_short("1", "3")
evaluates to 3, but alt_max_short("3", "1") evaluates to 1 -- not
exactly the maximum of 1 and 3.
In fact, I had to learn it the hard way by crashing my kernel in not
so funny ways by attempting to make use of the ALTENATIVE_2 macro
with alternatives where the first one was larger than the second
one.
According to [1] and commit dbe4058a6a44 ("x86/alternatives: Fix
ALTERNATIVE_2 padding generation properly") the right handed side
should read "-(-(a < b))" not "-(-(a - b))". Fix that, to make the
macro work as intended.
While at it, fix up the comments regarding the additional "-", too.
It's not about gas' usage of s32 but brain dead logic of having a
"true" value of -1 for the < operator ... *sigh*
Btw., the one in asm/alternative-asm.h is correct. And, apparently,
all current users of ALTERNATIVE_2() pass same sized alternatives,
avoiding to hit the bug.

Trying to reboot via real mode fails with PCID on: long mode cannot

I didn't catch this in testing because neither my computer nor my VM

Since the same carrier board may host RZ/G1M and RZ/G1N based
Systems on Module, the DT architecture for iwg20d-q7 needs
better decoupling. This patch provides:
* iwg20d-q7-common.dtsi - its purpose is to define the carrier
board definitions, and its content is basically the same
as the previous version of r8a7743-iwg20d-q7.dts, only it
has no reference to the SoM .dtsi, and that's why the
filename doesn't mention the SoC name any more.
* r8a7743-iwg20d-q7.dts - its new purpose is to put together
the SoM .dtsi (r8a7743-iwg20m.dtsi) and the carrier board
.dtsi defined by this very patch, along with "model" and
"compatible" properties.
The final DT architecture to describe the board is now:
r8a7743-iwg20d-q7.dts # Carrier Board + SoM
├── r8a7743-iwg20m.dtsi # SoM
│ └── r8a7743.dtsi # SoC
└── iwg20d-q7-common.dtsi # Carrier Board
and maximizes the reuse of the definitions for the carrier board
and for the SoM.

Support for Exynos4212 SoCs has been removed by commit bca9085e0ae9 ("ARM:
dts: exynos: remove Exynos4212 support (dead code)"), so there is no need
to keep remaining dead code related to this SoC version.

There is exactly one board in the kernel that defines platform data
for the GPIO NAND driver.
Use the feature to provide a lookup table for the GPIOs in the board
file so we can convert the driver as a whole to just use GPIO
descriptors.
After this we can cut the use of <linux/of_gpio.h> and use the GPIO
descriptor management from <linux/gpio/consumer.h> alone to grab and use
the GPIOs used in the driver.
I also created a local struct device *dev in the probe() function
because I was getting annoyed with all the &pdev->dev dereferencing.

In 32-bit mode, the x86 architecture can hold full 32-bit pointers.
Therefore, the code that copies the current address to the %ecx register
and uses %ecx-relative addressing is useless, we could just use absolute
addressing.
The processors have a stack of return addresses for branch prediction. If
we use a call instruction and pop the return address, it desynchronizes
the return stack and causes branch prediction misses.
This patch also moves the data to the .rodata section.
