ARM TWD and Global timer are clocked by PERIPHCLK which is MPU_CLK/2.
But now they are clocked by dpll_mpu_m2_ck == MPU_CLK and, as result.
Timekeeping core misbehaves. For example, execution of command
"sleep 5" will take 10 sec instead of 5.
Hence, fix it by adding mpu_periphclk ("fixed-factor-clock") and use
it for clocking ARM TWD and Global timer (same way as on OMAP4).

A runtime PM centric subsystem/driver may typically use the runtime PM
helpers, pm_runtime_force_suspend|resume() in the system PM path. This
means the genpd's runtime PM callbacks might be invoked even when runtime
PM has been disabled for the device.
To properly cope with these and similar scenarios when these helper
functions are used, change genpd to skip validating and measuring the
device PM QOS latency.
This is needed because otherwise genpd may prevent the device to be put
into low power state. If this occurs during system PM, it causes the
sequence to be aborted as a device's system PM callback returns -EBUSY.

ROL on a 32 bit integer with a shift of 32 or more is undefined and the
result is arch-dependent. Avoid this by handling the trivial case of
roling by 0 correctly.
The trivial solution of checking if shift is 0 breaks gcc's detection
of this code as a ROL instruction, which is unacceptable.
This bug was reported and fixed in GCC
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57157):
The standard rotate idiom,
(x << n) | (x >> (32 - n))
is recognized by gcc (for concreteness, I discuss only the case that x
is an uint32_t here).
However, this is portable C only for n in the range 0 < n < 32. For n
== 0, we get x >> 32 which gives undefined behaviour according to the
C standard (6.5.7, Bitwise shift operators). To portably support n ==
0, one has to write the rotate as something like
(x << n) | (x >> ((-n) & 31))
And this is apparently not recognized by gcc.
Note that this is broken on older GCCs and will result in slower ROL.

When you take a metadata snapshot the btree roots for the mapping and
details tree need to have their reference counts incremented so they
persist for the lifetime of the metadata snap.
The roots being incremented were those currently written in the
superblock, which could possibly be out of date if concurrent IO is
triggering new mappings, breaking of sharing, etc.
Fix this by performing a commit with the metadata lock held while taking
a metadata snapshot.

Lenovo Thinkpad T440s suffers from constant background noises, and it
seems to be a generic hardware issue on this model:
https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-speaker-noise/td-p/1339883
As the noise comes from the analog loopback path, disabling the path
is the easy workaround.
Also, the machine gives significant cracking noises at PM suspend. A
workaround found by trial-and-error is to disable the shutup callback
currently used for ALC269-variant.
This patch addresses these noise issues by introducing a new fixup
chain. Although the same workaround might be applicable to other
Thinkpad models, it's applied only to T440s (17aa:220c) in this patch,
so far, just to be safe (you chicken!). As a compromise, a new model
option string "tp440" is provided now, though, so that owners of other
Thinkpad models can test it more easily.

order of the pernet_subsys to avoid "use-before-initialised"

nfnetlink_subsys_register failed. This patch adds the necessary

Some ciphers actually support encrypting zero length plaintexts. For
example, many AEAD modes support this. The resulting ciphertext for
those winds up being only the authentication tag, which is a result of
the key, the iv, the additional data, and the fact that the plaintext
had zero length. The blkcipher constructors won't copy the IV to the
right place, however, when using a zero length input, resulting in
some significant problems when ciphers call their initialization
routines, only to find that the ->iv parameter is uninitialized. One
such example of this would be using chacha20poly1305 with a zero length
input, which then calls chacha20, which calls the key setup routine,
which eventually OOPSes due to the uninitialized ->iv member.

During driver probe, i2c_imx_init_recovery_info() must come before
i2c_add_numbered_adapter(), because the get/set_scl() functions
are assigned in i2c_register_adapter() under the conditon that bus
recover_info are initialized. Otherwise, get/set_scl() function
pointers never get assigned.
In such case, when i2c_generic_gpio_recovery() is used for bus recovery,
there will be kernel crash because bri->set_scl is NULL.
The solution to this bug is moving i2c_imx_init_recovery_info() before
i2c_register_adapter().

In this patch, I'm trying to change the code to use only normal

* For reading or writing a 32-bit word that may be unaligned when
an SKB contains unaligned data, I'm using get_unaligned/put_unaligned()
rather than memcpy_fromio/toio.
* For converting a u8 pointer to a u32 pointer, I use a cast rather
than the incorrect virt_to_phys.
* For copying a couple of bytes from one place to another while respecting
alignment, I use memcpy instead of memcpy_toio.

When an interface is brought up which was previously suspended (via
runtime PM), it would hang. This happens because napi_disable is called
before napi_enable.
Solve this by avoiding napi_enable in the resume during open function
(netif_running is true when open is called, IFF_UP is set after a
successful open; netif_running is false when close is called, but IFF_UP
is then still set).
While at it, remove WORK_ENABLE check from rtl8152_open (introduced with
the original change) because it cannot happen:
- After this patch, runtime resume will not set it during rtl8152_open.
- When link is up, rtl8152_open is not called.
- When link is down during system/auto suspend/resume, it is not set.

Commit bc69fdfc6c13
("net: thunderx: Enable BGX LMAC's RX/TX only after VF is up")
introduces lmac_cnt member and starts verifying VF number against it.
This is plain wrong, and works only because currently we have hardcoded
1:1 mapping between VFs and LMACs, and in this case num_vf_en and
lmac_cnt are always equal. However in future this may change, and the
code will badly misbehave. The worst consequence of this is failure to
deliver link status messages, causing VFs to go defunct because since
commit 0b72a9a1060e ("net: thunderx: Switchon carrier only upon
interface link up") VF will not fully bring itself up without it.
This patch fixes the potential problem by doing VF number checks against
the num_vf_en. Since lmac_cnt is not used anywhere else, it is removed.
Additionally some duplicated code is factored out into nic_enable_vf()

This reverts commit 527d10ef3a315d3cb9dc098dacd61889a6c26439.
The reverted commit breaks cxlflash devices following an EEH reset (and
possibly other cxl devices, however this has not been tested).
The reverted commit changed the behaviour of eeh_reset_device() so that PHB
PEs are not unfrozen following the completion of the reset. This should not
be problematic, as no device resources should have been associated with the
PHB PE.
However, when attempting to load the cxlflash driver after a reset, the
driver attempts to read Vital Product Data through a call to
pci_read_vpd() (which is called on the physical cxl device, not on the
virtual AFU device). pci_read_vpd() in turn attempts to read from the cxl
device's config space. This fails, as the PE it's trying to read from is
still frozen. In turn, the driver gets an -ENODEV and fails to initialise.
It appears this issue only affects some parts of the VPD area, as "lspci
-vvv", which only reads a subset of the VPD bytes, is not broken by the
original patch.
At this stage, we don't fully understand why we're trying to read a frozen
PE, and we don't know how this affects other cxl devices. It is possible
that there is an underlying bug in the cxl driver or the powerpc CAPI
support code, or alternatively a bug in the PCI resource allocation/mapping
code that is incorrectly mapping resources to PE#0.
As such, this fix is incomplete, however it is necessary to prevent a
serious regression in CAPI support.
In the meantime, revert the commit, especially as it was intended to be a
non-functional change.

This file was originally cloned off of the MPC8641D-HPCN reference

board does not. The bogus entry was largely inert and went undetected
until commit 321beec5047af83db90c88114b7e664b156f49fe ("net: phy: Use

With the above commit, the board fails to NFS boot since it sits waiting
for a PHY IRQ event that of course never arrives. Removing the bogus

As noted here [1], there are potentially future conflicts if we try to
use MTD's "partitions" subnode to describe anything besides just the
fixed-in-the-device-tree partitions currently described in this
document. Particularly, there was a proposal to use this node for the
AFS parser too.
It can pose a (small) problem to try to differentiate the following
nodes:
// using binding as currently specified
partitions {
#address-cells = <x>;
#size-cells = <y>;
partition@0 {
...;
};
};
and
// proposed future binding
partitions {
compatible = "arm,arm-flash-structure";
};
It's especially difficult if other uses of this node start having
subnodes.
So, since the "partitions" node is new in v4.4, let's fixup the binding
before release so that it requires a compatible property, so it's much
clearer to distinguish. e.g.:
// proposed
partitions {
compatible = "fixed-partitions";
#address-cells = <x>;
#size-cells = <y>;
partition@0 {
...;
};

NVIDIA have indicated that the workaround is required on all GK10[467]
boards that have the PGOB fuse set.
I've left the commandline option in place for now, as paranoia.

The remove_keys() logic is performed as garbage collection task. Such
task is intended to be run when no other active processes are running.
The need_resched() will return TRUE if there are user tasks to be
activated in near future.
In such case, we don't execute remove_keys() and postpone
the garbage collection work to try to run in next cycle,
in order to free CPU resources to other tasks.
The possible pseudo-code to trigger such scenario:
1. Allocate a lot of MR to fill the cache above the limit.
2. Wait a small amount of time "to calm" the system.
3. Start CPU extensive operations on multi-node cluster.
4. Expect performance degradation during MR cache shrink operation.

There are several hits that WR buffer allocation(kmalloc) failed.
It failed at order 3 and/or 4 contigous pages allocation. At the same time
there are actually 100MB+ free memory but well fragmented.
So try vmalloc when kmalloc failed.

Pull cgroup fixes from Tejun Heo:
"More change than I'd have liked at this stage. The pids controller
and the changes made to cgroup core to support it introduced and
revealed several important issues.
- Assigning membership to a newly created task and migrating it can
race leading to incorrect accounting. Oleg fixed it by widening
threadgroup synchronization. It looks like we'll be able to merge
it with a different percpu rwsem which is used in fork path making
things simpler and cheaper.
- The recent change to extend cgroup membership to zombies (so that
pid accounting can extend till the pid is actually released) missed
pinning the underlying data structures leading to use-after-free.
Fixed.
- v2 hierarchy was calling subsystem callbacks with the wrong target
cgroup_subsys_state based on the incorrect assumption that they
share the same target. pids is the first controller affected by
this. Subsys callbacks updated so that they can deal with
multi-target migrations"

The x86 FPU cleanup changed fpstate to a plain integer.
UML on x86 has to deal with that too.

On gcc Ubuntu 4.8.4-2ubuntu1~14.04, linking vmlinux fails with:
arch/um/os-Linux/built-in.o: In function `os_timer_create':

arch/um/os-Linux/built-in.o: In function `os_timer_set_interval':

arch/um/os-Linux/built-in.o: In function `os_timer_disable':
/android/kernel/android/arch/um/os-Linux/time.c:145: undefined reference to `timer_settime'
This is because -lrt appears in the generated link commandline
after arch/um/os-Linux/built-in.o. Fix this by removing -lrt from
arch/um/Makefile and adding it to the UM-specific section of
scripts/link-vmlinux.sh.
