Subject: [PATCH] iwlwifi: mvm: remove WARN_ON for invalid BA notification
The firmware frequently manages to trigger this, and there's
no known driver workaround, so stop warning.

Subject: [PATCH] Input - synaptics: pin 3 touches when the firmware reports 3
fingers
Synaptics PS/2 touchpad can send only 2 touches in a report. They can
detect 4 or 5 and this information is valuable.
In commit 63c4fda (Input: synaptics - allocate 3 slots to keep stability
in image sensors), we allocate 3 slots, but we still continue to report
the 2 available fingers. That means that the client sees 2 used slots while
there is a total of 3 fingers advertised by BTN_TOOL_TRIPLETAP.
For old kernels this is not a problem because max_slots was 2 and libinput/
xorg-synaptics knew how to deal with that. Now that max_slot is 3, the
clients ignore BTN_TOOL_TRIPLETAP and count the actual used slots (so 2).
It then gets confused when receiving the BTN_TOOL_TRIPLETAP and DOUBLETAP
information, and goes wild.
We can pin the 3 slots until we get a total number of fingers below 2.

Subject: [PATCH] Input: synaptics - re-route tracksticks buttons on the Lenovo
2015 series
The 2015 series of the Lenovo thinkpads added back the hardware buttons on
top of the touchpad for the trackstick.
Unfortunately, they are wired to the touchpad, and not the trackstick.
Thus, they are seen as extra buttons from the kernel point of view.
This leads to a problem in user space because extra buttons on synaptics
devices used to be used as scroll up/down buttons. So in the end, the
experience for the user is scroll events for buttons left and right when
using the trackstick. Yay!
Fortunately, the firmware advertises such behavior in the extended
capability $10, and so we can re-route the buttons through the pass-through
interface.

Subject: [PATCH] Input: synaptics - remove TOPBUTTONPAD property for Lenovos
2015
The 2015 series of the Lenovo thinkpads added back the hardware buttons on
top of the touchpad for the trackstick.
Unfortunately, Lenovo used the PNPIDs that are supposed to be "5 buttons"
touchpads, so the new laptops also have the INPUT_PROP_TOPBUTTONPAD. Yay!
Instead of manually removing each of the new ones, or hoping that we know
all the current ones, we can consider that the PNPIDs list that were given
contains touchpads that have the trackstick buttons, either physically
wired to them, or emulated with the top software button property.
Thanks to the extra buttons capability in query $10, we can reliably detect
the physical buttons from the software ones, and so we can remove the
TOPBUTTONPAD property even if it was declared as such.

Subject: [PATCH] Input: synaptics - remove X1 Carbon 3rd gen from the
topbuttonpad list
Lenovo decided to switch back to physical buttons for the trackstick on
their latest series. The PNPId list was provided before they reverted back
to physical buttons, so it contains the new models too. We can know from
the touchpad capabilities that the touchpad has physical buttons, so
removing the ids from the list is not mandatory. It is still nicer to
remove the wrong ids, so start by removing the X1 Carbon 3rd gen, with the
PNPId of LEN0048.

Subject: [PATCH] Input: synaptics - remove X250 from the topbuttonpad list
Lenovo X250 has a PnpID of LEN0046, but it does not have the top software
button requirement.
For the record, Lenovo T450s and W541 have a PnpID of LEN200f and LEN004a,
so they are not on the top software button list.

Subject: [PATCH] SCSI: add 1024 max sectors black list flag
This works around a issue with qnap iscsi targets not handling large IOs
very well.
The target returns:
VPD INQUIRY: Block limits page (SBC)
Maximum compare and write length: 1 blocks
Optimal transfer length granularity: 1 blocks
Maximum transfer length: 4294967295 blocks
Optimal transfer length: 4294967295 blocks
Maximum prefetch, xdread, xdwrite transfer length: 0 blocks
Maximum unmap LBA count: 8388607
Maximum unmap block descriptor count: 1
Optimal unmap granularity: 16383
Unmap granularity alignment valid: 0
Unmap granularity alignment: 0
Maximum write same length: 0xffffffff blocks
Maximum atomic transfer length: 0
Atomic alignment: 0
Atomic transfer length granularity: 0
and it is *sometimes* able to handle at least one IO of size up to 8 MB. We
have seen in traces where it will sometimes work, but other times it
looks like it fails and it looks like it returns failures if we send
multiple large IOs sometimes. Also it looks like it can return 2 different
errors. It will sometimes send iscsi reject errors indicating out of
resources or it will send invalid cdb illegal requests check conditions.
And then when it sends iscsi rejects it does not seem to handle retries
when there are command sequence holes, so I could not just add code to
try and gracefully handle that error code.
The problem is that we do not have a good contact for the company,
so we are not able to determine under what conditions it returns
which error and why it sometimes works.
So, this patch just adds a new black list flag to set targets like this to
the old max safe sectors of 1024. The max_hw_sectors changes added in 3.19
caused this regression, so I also ccing stable.

Subject: [PATCH] arm64: avoid needing console= to enable serial console
Tell kernel to prefer one of the serial ports for console on
platforms currently supported (pl011 or 8250). console= on
command line will override these assumed preferences. This is
just a hack to get the behavior we want from DT provided by
firmware.

blk-loop-avoid-too-many-pending-per-work-IO.patch Normal file

@ -0,0 +1,104 @@
If there are too many pending per work I/O, too many
high priority work thread can be generated so that
system performance can be effected.
This patch limits the max pending per work I/O as 16,
and will fackback to single queue mode when the max
number is reached.
This patch fixes Fedora 22 live booting performance
regression when it is booted from squashfs over dm
based on loop, and looks the following reasons are
related with the problem:
- not like other filesyststems(such as ext4), squashfs
is a bit special, and I observed that increasing I/O jobs
to access file in squashfs only improve I/O performance a
little, but it can make big difference for ext4
- nested loop: both squashfs.img and ext3fs.img are mounted
as loop block, and ext3fs.img is inside the squashfs
- during booting, lots of tasks may run concurrently

From: Rob Clark <robdclark@gmail.com>

Subject: [PATCH] drm/i915: tame the chattermouth (v2)
Many distro's have mechanism in place to collect and automatically file
bugs for failed WARN()s. And since i915 has a lot of hw state sanity
checks which result in WARN(), it generates quite a lot of noise which
is somewhat disconcerting to the end user.
Separate out the internal hw-is-in-the-state-I-expected checks into
I915_STATE_WARN()s and allow configuration via i915.verbose_checks module
param about whether this will generate a full blown stacktrace or just
DRM_ERROR(). The new moduleparam defaults to true, so by default there
is no change in behavior. And even when disabled, you will still get
an error message logged.
v2: paint the macro names blue, clarify that the default behavior
remains the same as before

From: Peter Jones <pjones@redhat.com>
Date: Tue, 18 Nov 2014 10:18:22 -0500
Subject: [PATCH] efi: Add esrt support.
Add sysfs files for the EFI System Resource Table (ESRT) under
/sys/firmware/efi/esrt and for each EFI System Resource Entry under
entries/ as a subdir.
The EFI System Resource Table (ESRT) provides a read-only catalog of
system components for which the system accepts firmware upgrades via
UEFI's "Capsule Update" feature. This module allows userland utilities
to evaluate what firmware updates can be applied to this system, and
potentially arrange for those updates to occur.
The ESRT is described as part of the UEFI specification, in version 2.5
which should be available from http://uefi.org/specifications in early
2015. If you're a member of the UEFI Forum, information about its
addition to the standard is available as UEFI Mantis 1090.
For some hardware platforms, additional restrictions may be found at
http://msdn.microsoft.com/en-us/library/windows/hardware/jj128256.aspx ,
and additional documentation may be found at
http://download.microsoft.com/download/5/F/5/5F5D16CD-2530-4289-8019-94C6A20BED3C/windows-uefi-firmware-update-platform.docx

Subject: [PATCH] md/raid0: fix restore to sector variable in
raid0_make_request
md/raid0: fix restore to sector variable in raid0_make_request
The variable "sector" in "raid0_make_request()" was improperly updated
by a call to "sector_div()" which modifies its first argument in place.
Commit 47d68979cc968535cb87f3e5f2e6a3533ea48fbd restored this variable
after the call for later re-use. Unfortunetly the restore was done after
the referenced variable "bio" was advanced. This lead to the original
value and the restored value being different. Here we move this line to
the proper place.
One observed side effect of this bug was discarding a file though
unlinking would cause an unrelated file's contents to be discarded.

Subject: [PATCH] ovl: don't remove non-empty opaque directory
When removing an opaque directory we can't just call rmdir() to check for
emptiness, because the directory will need to be replaced with a whiteout.
The replacement is done with RENAME_EXCHANGE, which doesn't check
emptiness.
Solution is just to check emptiness by reading the directory. In the
future we could add a new rename flag to check for emptiness even for
RENAME_EXCHANGE to optimize this case.

Subject: [PATCH] vhost/scsi: potential memory corruption
This code in vhost_scsi_make_tpg() is confusing because we limit "tpgt"
to UINT_MAX but the data type of "tpg->tport_tpgt" and that is a u16.
I looked at the context and it turns out that in
vhost_scsi_set_endpoint(), "tpg->tport_tpgt" is used as an offset into
the vs_tpg[] array which has VHOST_SCSI_MAX_TARGET (256) elements so
anything higher than 255 then it is invalid. I have made that the limit
now.
In vhost_scsi_send_evt() we mask away values higher than 255, but now
that the limit has changed, we don't need the mask.

Subject: [PATCH] x86/microcode/intel: Guard against stack overflow in the
loader
mc_saved_tmp is a static array allocated on the stack, we need to make
sure mc_saved_count stays within its bounds, otherwise we're overflowing
the stack in _save_mc(). A specially crafted microcode header could lead
to a kernel crash or potentially kernel execution.
