[ Upstream commit bba8376aea1dcbbe22bbda118c52abee317c7609 ]
The reboot quirk for ASUS EeeBook X205TA contains a typo in
DMI_PRODUCT_NAME, improperly referring to X205TAW instead of
X205TA, which prevents the quirk from being triggered. The
model X205TAW already has a reboot quirk of its own.
This fix simply removes the inappropriate final letter W.

[ Upstream commit 71050ae7bf83e4d71a859257d11adc5de517073e ]
Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:
Scope (_SB)
{
(...)
Device (ATKD)
{
(...)
Method (WMNB, 3, Serialized)
{
(...)
If (LEqual (IIA0, 0x00010002))
{
OWGD (IIA1)
Return (One)
}
}
}
}
So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.
This commit skips registering RFKill switches at all for these laptops,
to allow the asus-wireless driver to drive the airplane mode LED
correctly through the ASHS ACPI device. Relying on the presence of ASHS
and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least
21 different laptops.

[ Upstream commit 0b445549ea6f91ffea78a976fe89b932db6e077a ]
In soft (no-reboot) mode, the driver self-pings watchdog upon expiration
of an interrupt. However the interrupt itself was not cleared thus on
first hit, the system enters infinite interrupt handling loop.
On Odroid U3 (Exynos4412), when booted with s3c2410_wdt.soft_noboot=1
argument the console is flooded:
# killall -9 watchdog
[ 60.523760] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq)
[ 60.536744] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq)
Fix this by writing something to the WTCLRINT register to clear the
interrupt. The register WTCLRINT however appeared in S3C6410 so a new
watchdog quirk and flavor are needed.

[ Upstream commit 33be632b8443b6ac74aa293504f430604fb9abeb ]
The Qualcomm QDF2xxx root ports don't advertise an ACS capability, but they
do provide ACS-like features to disable peer transactions and validate bus
numbers in requests.
To be specific:
* Hardware supports source validation but it will report the issue as
Completer Abort instead of ACS Violation.
* Hardware doesn't support peer-to-peer and each root port is a root
complex with unique segment numbers.
* It is not possible for one root port to pass traffic to the other root
port. All PCIe transactions are terminated inside the root port.
Add an ACS quirk for the QDF2400 and QDF2432 products.

[ Upstream commit e9acc77dd046b22c7ebf70e35f68968978445f8b ]
Initially all QorIQ platforms were PowerPC architecture and they didn't
support card detection except several platforms. The driver added the
quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION as default and this made broken-cd
property in dts node didn't work. Now QorIQ platform turns to ARM
architecture and most of them could support card detection. However it's
a large number of dts trees that need to be fixed with broken-cd if we
remove the default SDHCI_QUIRK_BROKEN_CARD_DETECTION in driver. And the
users don't want to see this. So this patch is to remove this default
quirk just for ARM and keep it for PowerPC.(Note, QorIQ PowerPC platform
only has big-endian eSDHC while QorIQ ARM platform has big-endian or
little-endian eSDHC) This makes broken-cd property work again for ARM.

[ Upstream commit ce709f86501a013e941e9986cb072eae375ddf3e ]
The Broadcom Northstar2 SoC has a number of quirks for the PAXC
(internal/fake) PCI bus. Specifically, the PCI config space is shared
between the root port and the first PF (ie., PF0), and a number of fields
are tied to zero (thus preventing them from being set). These cannot be
"fixed" in device firmware, so we must fix them with a quirk.

[ Upstream commit 82bcd087029f6056506ea929f11af02622230901 ]
This patch adds a Qualcomm specific quirk to the arm_smccc_smc call.
On Qualcomm ARM64 platforms, the SMC call can return before it has
completed. If this occurs, the call can be restarted, but it requires
using the returned session ID value from the interrupted SMC call.
The quirk stores off the session ID from the interrupted call in the
quirk structure so that it can be used by the caller.
This patch folds in a fix given by Sricharan R:

The quirk structure allows for specialized SMC operations due to SoC
specific requirements. The current arm_smccc_(smc/hvc) is renamed and

the arm_smccc_(smc/hvc)_quirk function.

[ Upstream commit e7deb1570a527d3c74be4e21a72b1b459605c501 ]
Non-generic devices have numbered_buttons set for both pen and
touch interfaces by default. The actual number of buttons on the
interface is normally manually decided later, which is different
from what those HID generic devices are processed, where number
of buttons are directly retrieved from HID descriptors.
This patch adds the missed HID_GENERIC check and moves the statement
to wacom_setup_pad_input_capabilities since it's not a quirk anymore.

[ Upstream commit 77e9a4aa9de10cc1418bf9a892366988802a8025 ]
More and more platforms need the button.lid_init_state=open quirk. This
patch sets it the default behavior.
If a platform doesn't send lid open event or lid open event is lost due to
the underlying system problems, then we can compare various combinations:
1. systemd/acpid is used to suspend system or not, systemd has a special
logic forcing open event after resuming;
2. _LID returns a cached value or not.
The result is as follows:
1. lid_init_state=method
1. cached
1. resumed by lid:
(x) event=close
(x) systemd=suspends again
(x) acpid=suspends again
(x) state=close
2. resumed by other:
(o) event=close
(x) systemd=suspends again
(x) acpid=suspends again
(o) state=close
2. non-cached
1. resumed by lid:
(o) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=open
2. resumed by other:
(o) event=close
(x) systemd=suspends again
(x) acpid=suspends again
(o) state=close
2. lid_init_state=open
1. cached
1. resumed by lid:
(o) event=open
(o) systemd=resumes
(o) acpid=resumes
(x) state=close
2. resumed by other:
(x) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=close
2. non-cached
1. resumed by lid:
(o) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=open
2. resumed by other:
(x) event=open
(o) systemd=resumes
(o) acpid=resumes
(o) state=close
3. lid_init_state=ignore
1. cached
1. resumed by lid:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(x) state=close
2. resumed by other:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(o) state=close
2. non-cached
1. resumed by lid:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(o) state=open
2. resumed by other:
(o) event=none
(x) systemd=suspends again
(o) acpid=resumes
(o) state=close
As a conclusion:
1. With systemd changed, lid_init_state=ignore has only one problem and the
problem comes from an underlying issue, not userspace and kernel lid
handling.
2. Without systemd changed, lid_init_state=open can be the default
behavior as the pass ratio is not much worse than lid_init_state=ignore.
3. lid_init_state=method is buggy, we can have a separate patch to make it
deprectated.

[ Upstream commit 41135de1e7fd14c6fcb9158404ba5c8fb97bf259 ]
Some devices from Texas Instruments [1] suffer from
a silicon bug where Port Enabled/Disabled bit

The bug is so that if port is disabled with PED

problem lies with SNPS USB IP and this affects
all known versions up to 3.00a. A separate
patch will be added to dwc3 to enabled this
quirk flag if version is <= 3.00a.

UART uses as EDMA as dma engine on AM437x SoC and therefore, requires
OMAP_DMA_TX_KICK quirk just like AM33xx. So, enable OMAP_DMA_TX_KICK
quirk for AM437x platform as well. While at that, drop use of
of_machine_is_compatible() and instead pass quirks via device data.

[ Upstream commit dd3749099cfa2c80039193c438b90f3160eaf7f9 ]
The core framework already handles setting this parameter with a
platform quirk. Add the appropriate flag so that we always set
AHBBURST to 0. Technically DT should be doing this, but we always
do it for msm chipidea devices so setting the flag in the driver
works just as well. If the burst needs to be anything besides 0,
we expect the 'ahb-burst-config' dts property to be present.

[ Upstream commit 98b2f01c8dfc8922a2af1fe82a1c40cac4911634 ]
Back in 2014, commit fb7023e0e248 ("drm/i915: BDW: Adding Reserved PCI
IDs.") added the reserved PCI IDs in order to try to make sure we had
working drivers in case we ever released products using these IDs
(since we had instances of this type of problem in the past). The
problem is that the patch only touched the macros used by
early-quirks.c and by the user space components that rely on
i915_pciids.h, it didn't touch the macros used by i915_pci.c. So we
correctly handled the stolen memory for these theoretical IDs, but we
didn't actually drive the devices from i915.ko.
So this patch fixes the original commit by actually making i915.ko
drive these IDs, which was the goal. There's no information on what
would be the GT count on these IDs, so we just go with the safer
intel_broadwell_info, at the risk of ignoring a possibly inexistent
BSD2_RING.
I did some checking, and it seems that these IDs are driven by
intel-gpu-tools, xf86-video-intel and libdrm (since they contain old
copies of i915_pciids.h), but they are not checked by mesa.
The alternative to this patch would be to just assume we're actually
never going to use these IDs, and then remove them from our ID lists
and make sure our user space components sync the latest i915_pciids.h
copy. I'm fine with either approaches, as long as we make sure that
every component tries to drive the same list of PCI IDs.

commit f5b98461cb8167ba362ad9f74c41d126b7becea7 upstream.
Now that our crng uses chacha20, we can rely on its speedy
characteristics for replacing MD5, while simultaneously achieving a
higher security guarantee. Before the idea was to use these functions if
you wanted random integers that aren't stupidly insecure but aren't
necessarily secure either, a vague gray zone, that hopefully was "good
enough" for its users. With chacha20, we can strengthen this claim,
since either we're using an rdrand-like instruction, or we're using the
same crng as /dev/urandom. And it's faster than what was before.
We could have chosen to replace this with a SipHash-derived function,
which might be slightly faster, but at the cost of having yet another
RNG construction in the kernel. By moving to chacha20, we have a single
RNG to analyze and verify, and we also already get good performance
improvements on all platforms.
Implementation-wise, rather than use a generic buffer for both
get_random_int/long and memcpy based on the size needs, we use a
specific buffer for 32-bit reads and for 64-bit reads. This way, we're
guaranteed to always have aligned accesses on all platforms. While
slightly more verbose in C, the assembly this generates is a lot
simpler than otherwise.
Finally, on 32-bit platforms where longs and ints are the same size,
we simply alias get_random_int to get_random_long.

commit 0115f6cbf26663c86496bc56eeea293f85b77897 upstream.
On VTLB+FTLB platforms (such as Loongson-3A R2), FTLB's pagesize is
usually configured the same as PAGE_SIZE. In such a case, Huge page
entry is not suitable to write in FTLB.
Unfortunately, when a huge page is created, its page table entries
haven't created immediately. Then the TLB refill handler will fetch an
invalid page table entry which has no "HUGE" bit, and this entry may be
written to FTLB. Since it is invalid, TLB load/store handler will then
use tlbwi to write the valid entry at the same place. However, the
valid entry is a huge page entry which isn't suitable for FTLB.
Our solution is to modify build_huge_handler_tail. Flush the invalid
old entry (whether it is in FTLB or VTLB, this is in order to reduce
branches) and use tlbwr to write the valid new entry.

commit 5a34133167dce36666ea054e30a561b7f4413b7f upstream.
Loongson-3's micro TLB (ITLB) is not strictly a subset of JTLB. That
means: when a JTLB entry is replaced by hardware, there may be an old
valid entry exists in ITLB. So, a TLB miss exception may occur while
handle_ri_rdhwr() is running because it try to access EPC's content.
However, handle_ri_rdhwr() doesn't clear EXL, which makes a TLB Refill
exception be treated as a TLB Invalid exception and tlbp may fail. In
this case, if FTLB (which is usually set-associative instead of set-
associative) is enabled, a tlbp failure will cause an invalid tlbwi,
which will hang the whole system.
This patch rename handle_ri_rdhwr_vivt to handle_ri_rdhwr_tlbp and use
it for Loongson-3. It try to solve the same problem described as below,
but more straightforwards.
https://patchwork.linux-mips.org/patch/12591/
I think Loongson-2 has the same problem, but it has no FTLB, so we just
keep it as is.

commit 4b5347a24a0f2d3272032c120664b484478455de upstream.
When building for microMIPS we need to ensure that the assembler always
knows that there is code at the target of a branch or jump. Recent
toolchains will fail to link a microMIPS kernel when this isn't the case
due to what it thinks is a branch to non-microMIPS code.
mips-mti-linux-gnu-ld kernel/built-in.o: .spinlock.text+0x2fc: Unsupported branch between ISA modes.
mips-mti-linux-gnu-ld final link failed: Bad value
This is due to inline assembly labels in spinlock.h not being followed
by an instruction mnemonic, either due to a .subsection pseudo-op or the
end of the inline asm block.
Fix this with a .insn direction after such labels.
