commit cdd10409914184c7eee5ae3e11beb890c9c16c61 upstream.
The "dmas" cells for the designware DMA controller need to have only 3
properties apart from the phandle: request line, src master and
destination master. But the commit 6e8887f60f60 updated it incorrectly
while moving from platform code to DT. Fix it.

(cherry picked from commit 12c69f1e94c89d40696e83804dd2f0965b5250cd)
The 'noreplace-paravirt' option disables paravirt patching, leaving the
original pv indirect calls in place.
That's highly incompatible with retpolines, unless we want to uglify
paravirt even further and convert the paravirt calls to retpolines.
As far as I can tell, the option doesn't seem to be useful for much
other than introducing surprising corner cases and making the kernel
vulnerable to Spectre v2. It was probably a debug option from the early
paravirt days. So just remove it.

commit da285121560e769cc31797bba6422eea71d473e0 upstream.
Add a spectre_v2= option to select the mitigation used for the indirect
branch speculation vulnerability.
Currently, the only option available is retpoline, in its various forms.
This will be expanded to cover the new IBRS/IBPB microcode features.
The RETPOLINE_AMD feature relies on a serializing LFENCE for speculation
control. For AMD hardware, only set RETPOLINE_AMD if LFENCE is a
serializing instruction, which is indicated by the LFENCE_RDTSC feature.
[ tglx: Folded back the LFENCE/AMD fixes and reworked it so IBRS
integration becomes simple ]

commit 87590ce6e373d1a5401f6539f0c59ef92dd924a9 upstream.
As the meltdown/spectre problem affects several CPU architectures, it makes
sense to have common way to express whether a system is affected by a
particular vulnerability or not. If affected the way to express the
mitigation should be common as well.
Create /sys/devices/system/cpu/vulnerabilities folder and files for
meltdown, spectre_v1 and spectre_v2.
Allow architectures to override the show function.

Added "nokaiser" boot option: an early param like "noinvpcid".
Most places now check int kaiser_enabled (#defined 0 when not
CONFIG_KAISER) instead of #ifdef CONFIG_KAISER; but entry_64.S
and entry_64_compat.S are using the ALTERNATIVE technique, which
patches in the preferred instructions at runtime. That technique
is tied to x86 cpu features, so X86_FEATURE_KAISER is fabricated.
Prior to "nokaiser", Kaiser #defined _PAGE_GLOBAL 0: revert that,
but be careful with both _PAGE_GLOBAL and CR4.PGE: setting them when
nokaiser like when !CONFIG_KAISER, but not setting either when kaiser -
neither matters on its own, but it's hard to be sure that _PAGE_GLOBAL
won't get set in some obscure corner, or something add PGE into CR4.
By omitting _PAGE_GLOBAL from __supported_pte_mask when kaiser_enabled,
all page table setup which uses pte_pfn() masks it out of the ptes.
It's slightly shameful that the same declaration versus definition of
kaiser_enabled appears in not one, not two, but in three header files
(asm/kaiser.h, asm/pgtable.h, asm/tlbflush.h). I felt safer that way,
than with #including any of those in any of the others; and did not
feel it worth an asm/kaiser_enabled.h - kernel/cpu/common.c includes
them all, so we shall hear about it if they get out of synch.
Cleanups while in the area: removed the silly #ifdef CONFIG_KAISER
from kaiser.c; removed the unused native_get_normal_pgd(); removed
the spurious reg clutter from SWITCH_*_CR3 macro stubs; corrected some
comments. But more interestingly, set CR4.PSE in secondary_startup_64:
the manual is clear that it does not matter whether it's 0 or 1 when
4-level-pts are enabled, but I was distracted to find cr4 different on
BSP and auxiliaries - BSP alone was adding PSE, in probe_page_size_mask().

Introduce the "lrclk-strength" property to allow LRCLK pad drive strength
to be changed via device tree.
When running a stress playback loop test on a mx6dl wandboard channel
swap can be noticed on about 10% of the times.
While debugging this issue I noticed that when probing the SGTL5000
LRCLK pin with the scope the swap did not happen. After removing
the probe the swap started to happen again.
After changing the LRCLK pad drive strength to the maximum value the
issue is gone.
Same fix works on a mx6dl Colibri board as well.

The m41t0 variant is very similar to the already supported m41t00
variant, with the notable exception of the oscillator fail bit.
The data sheet notes:
If the oscillator fail (OF) bit is internally set to a '1,' this
indicates that the oscillator has either stopped, or was stopped
for some period of time and can be used to judge the validity of
the clock and date data.
The bit will get cleared with a regular write of the system time,
so no changes are needed to clear it.

commit 68615eb01f82256c19e41967bfb3eef902f77033 upstream.
With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver
is not always capable of avoiding the 25-35 ms timeout as specified by
the SMBUS protocol. This may cause silent corruption of the last bit of
any transfer, e.g. a one is read instead of a zero if the sensor chip
times out. This also affects the eeprom half of the nxp-se97 chip, where
this silent corruption was originally noticed. Other I2C adapters probably
suffer similar issues, e.g. bit-banging comes to mind as risky...
The SMBUS register in the nxp chip is not a standard Jedec register, but
it is not special to the nxp chips either, at least the atmel chips
have the same mechanism. Therefore, do not special case this on the
manufacturer, it is opt-in via the device property anyway.

[ Upstream commit 34c55cf2fc75f8bf6ba87df321038c064cf2d426 ]
Currently dp83867 driver returns error if phy interface type
PHY_INTERFACE_MODE_RGMII_RXID is used to set the rx only internal
delay. Similarly issue happens for PHY_INTERFACE_MODE_RGMII_TXID.
Fix this by checking also the interface type if a particular delay
value is missing in the phy dt bindings. Also update the DT document
accordingly.

[ Upstream commit 61976fff20f92aceecc3670f6168bfc57a79e047 ]
When the binding was defined, I was not aware that mt2701 was an earlier
version of the SoC. For sake of consistency, the ethernet driver should
use mt2701 inside the compat string as this is the earliest SoC with the
ethernet core.
The ethernet driver is currently of no real use until we finish and
upstream the DSA driver. There are no users of this binding yet. It should
be safe to fix this now before it is too late and we need to provide
backward compatibility for the mt7623-eth compat string.

[ Upstream commit 308d3165d8b2b98d3dc3d97d6662062735daea67 ]
The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.
While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.
In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.

commit 1be7107fbe18eed3e319a6c3e83c78254b693acb upstream.
Stack guard page is a useful feature to reduce a risk of stack smashing
into a different mapping. We have been using a single page gap which
is sufficient to prevent having stack adjacent to a different mapping.
But this seems to be insufficient in the light of the stack usage in
userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
which is 256kB or stack strings with MAX_ARG_STRLEN.
This will become especially dangerous for suid binaries and the default
no limit for the stack size limit because those applications can be
tricked to consume a large portion of the stack and a single glibc call
could jump over the guard page. These attacks are not theoretical,
unfortunatelly.
Make those attacks less probable by increasing the stack guard gap
to 1MB (on systems with 4k pages; but make it depend on the page size
because systems with larger base pages might cap stack allocations in
the PAGE_SIZE units) which should cover larger alloca() and VLA stack
allocations. It is obviously not a full fix because the problem is
somehow inherent, but it should reduce attack space a lot.
One could argue that the gap size should be configurable from userspace,
but that can be done later when somebody finds that the new 1MB is wrong
for some special case applications. For now, add a kernel command line
option (stack_guard_gap) to specify the stack gap size (in page units).
Implementation wise, first delete all the old code for stack guard page:
because although we could get away with accounting one extra page in a
stack vma, accounting a larger gap can break userspace - case in point,
a program run with "ulimit -S -v 20000" failed when the 1MB gap was
counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
and strict non-overcommit mode.
Instead of keeping gap inside the stack vma, maintain the stack guard
gap as a gap between vmas: using vm_start_gap() in place of vm_start
(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
places which need to respect the gap - mainly arch_get_unmapped_area(),
and and the vma tree's subtree_gap support for that.

Driver can now work with both ID and VBUS pins or either one of
them.
There can be the following 3 cases
1) Both ID and VBUS GPIOs are available:
ID = LOW -> USB_HOST active, USB inactive
ID = HIGH -> USB_HOST inactive, USB state is same as VBUS.
2) Only ID GPIO is available:
ID = LOW -> USB_HOST active, USB inactive
ID = HIGH -> USB_HOST inactive, USB active
3) Only VBUS GPIO is available:
VBUS = LOW -> USB_HOST inactive, USB inactive
VBUS = HIGH -> USB_HOST inactive, USB active
