Pull MIPS fixes from Ralf Baechle:
"This is the final pull request for MIPS for 4.4. It fixes:
- scripts/ld-version.sh parsing of ld version numbers that contain
large numbers as components.
- fix parsing of version numbers as used by Fedora's ld.
Currently scripts/ld-version.sh is only being used by MIPS"
[ This obviously missed 4.4, so getting merged now in the merge window
for 4.5 instead ]
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
ld-version: Fix it on Fedora
Fix ld-version.sh to handle large 3rd version part
Ivaylo Dimitrov reported a regression caused by commit 7866a62104
("dev: add per net_device packet type chains").
skb->dev becomes NULL and we crash in __netif_receive_skb_core().
Before above commit, different kind of bugs or corruptions could happen
without major crash.
But the root cause is that phonet_rcv() can queue skb without checking
if skb is shared or not.
Many thanks to Ivaylo Dimitrov for his help, diagnosis and tests.

It used to be that bus->irq was a pointer but after e7f4dc3536
('mdio: Move allocation of interrupts into core') it's an array inside
the mdio struct, so it can never be NULL. Let's remove the check.

If bus = kzalloc() fails then we end up dereferencing bus when we do
"bus->irq[i] = PHY_POLL;". The code is a little simpler if we reverse
the NULL check and return directly on failure.

Commit 7f5f873c6a ("rculist: Use WRITE_ONCE() when deleting from
reader-visible list") added the use of the WRITE_ONCE macro to the
kernel version of list.h, which broke the stacktool build because the
tools list.h includes the kernel list.h.
Avoid this type of situation in the future and make list.h
self-sufficient by copying the kernel list.h routines directly into
tools list.h.
This is a straight copy except for adjustments to the include statements
and copying of the tools-specific list routines (list_del_range and
list_for_each_from).

Pavel noted that lguest maps the switcher code executable and
read-write. This is a bad idea for any kernel text, but
particularly for text mapped at a fixed address.
Create two vmas, one for the text (PAGE_KERNEL_RX) and another
for the stacks (PAGE_KERNEL). Use VM_NO_GUARD to map them
adjacent (as expected by the rest of the code).

When "eagerfpu=off" is given as a command-line input, the kernel
should disable AVX support.
The Task Switched bit used for lazy context switching does not
support AVX. If AVX is enabled without eagerfpu context
switching, one task's AVX state could become corrupted or leak
to other tasks. This is a bug and has bad security implications.
This only affects systems that have AVX/AVX2/AVX512 and this
issue will be found only when one actually uses AVX/AVX2/AVX512
_AND_ does eagerfpu=off.
Reference: Intel Software Developer's Manual Vol. 3A
Sec. 2.5 Control Registers:
TS Task Switched bit (bit 3 of CR0) -- Allows the saving of the
x87 FPU/ MMX/SSE/SSE2/SSE3/SSSE3/SSE4 context on a task switch
to be delayed until an x87 FPU/MMX/SSE/SSE2/SSE3/SSSE3/SSE4
instruction is actually executed by the new task.
Sec. 13.4.1 Using the TS Flag to Control the Saving of the X87
FPU and SSE State
When the TS flag is set, the processor monitors the instruction
stream for x87 FPU, MMX, SSE instructions. When the processor
detects one of these instructions, it raises a
device-not-available exeception (#NM) prior to executing the
instruction.

This issue is a fallout from the command-line parsing move.
When "eagerfpu=off" is given as a command-line input, the kernel
should disable MPX support. The decision for turning off MPX was
made in fpu__init_system_ctx_switch(), which is after the
selection of the XSAVE format. This patch fixes it by getting
that decision done earlier in fpu__init_system_xstate().

using the 'init optimization' (i.e. xsaveopt, xsaves). We

ldt_gdt.c relies on cross-cpu invalidation of SS to do one of
its tests. On 32-bit builds, this works fine, but on 64-bit
builds, it only works if the kernel has proper SS sigcontext
handling for 64-bit user programs.
Since the SS fixes are currently reverted, restrict the test
case to 32 bits for now.
In principle, I could change the test to use a different segment
register, but it would be messy: CS can't point to the LDT for
64-bit code, and the other registers don't result in immediate
faults because they aren't reloaded on kernel -> user
transitions.
When we fix sigcontext (in 4.6?), we can revert this.

Correction (FEC) support that has been added to the DM verity target.

- A stable fix for hung IO if a DM snapshot copy hit an error
- A few small cleanups in DM core and DM persistent data.
- A couple DM thinp range discard improvements (address atomicity of
finding a range and the efficiency of discarding a partially mapped
thin device)
- Add ability to debug DM bufio leaks by recording stack trace when a
buffer is allocated. Upon detected leak the recorded stack is dumped.

There's no real overall theme to the regmap changes for this release,
it's a collection of individual features. The main bits are:
- Support for 64 bit registers, mainly for MMIO use, from Xiubo Li.
- Support for trigger type configuration for regmap-irq from Laxman
Dewangan.
- Use native physical I/O for MMIO register maps to avoid confusion
with the conversions that readl() and writel() do to little endian on
big endian systems (with some DT updates to fix some workarounds
people were doing), code from Simon Arlott.
- Use a binary search rather than iteraton to improve the runtime
performance of the rbtree code from Nikesh Oswal.

Merge tag 'pinctrl-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control patches for the v4.5 series.
Notably I have a patch to driver core from Stephen Boyd in the pull
request, this has been ACKed by Greg so it should be OK. The internal
API needed some tweaking to allow modular Qualcomm pin controllers.
There is a bit of development history in here but it should all add up
nicely and has boiled in linux-next. For example I merged in v4.4-rc5
to get rid of some nasty merge conflicts.

Pull libata updates from Tejun Heo:
"Mostly low level driver specific changes.
Two changes are somewhat noteworthy. First, Dan's patchset to support
per-port msix interrupt handling for ahci, which was tried last cycle
but had to be backed out due to a couple issues, is back and seems to
be working fine. Second, libata exception handling now uses
usleep_range() instead of msleep() for sleeps < 20ms which can make
things snappier in some corner cases"

Workqueue now has a stall detector which dumps workqueue state if any
worker pool hasn't made forward progress over a certain amount of time
(30s by default) and also triggers a warning if a workqueue which can
be used in memory reclaim path tries to wait on something which can't
be.
These should make workqueue hangs a lot easier to debug."
