The driver still struggles with firmwares that do not replay to the OS
version request. It is safe not waiting for the replay. First, the driver
doesn't do anything with the replay second the connection is closed
immediately, hence the packet will be just safely discarded in case it
is received and last the driver won't get stuck if the firmware won't
reply.

This patch fixes 'mei: synchronize irq before initiating a reset'
The patch had introduced a deadlock between irq thread and mei_reset()
as they are both holding the same device lock.
---> device_lock:
mei_reset()
<---- interrupt thread
device_lock
---> synchornize_irq()
wait on interrupt thread == (dead lock)
The fix is to call synchronize_irq
prior to call locked mei_reset function.

I mistakenly added the code to release sk->sk_frag in

TCP sockets using sk->sk_allocation == GFP_ATOMIC do no call

Newer hardware does not provide a cumulative payload length when multiple
descriptors are needed to handle the data. Once the MTU increases beyond
the size that can be handled by a single descriptor, the SKB does not get
built properly by the driver.
The driver will now calculate the size of the data buffers used by the
hardware. The first buffer of the first descriptor is for packet headers
or packet headers and data when the headers can't be split. Subsequent
descriptors in a multi-descriptor chain will not use the first buffer. The
second buffer is used by all the descriptors in the chain for payload data.
Based on whether the driver is processing the first, intermediate, or last
descriptor it can calculate the buffer usage and build the SKB properly.
Tested and verified on both old and new hardware.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree, a
rather large batch of fixes targeted to nf_tables, conntrack and bridge
netfilter. More specifically, they are:
1) Don't track fragmented packets if the socket option IP_NODEFRAG is set.
From Florian Westphal.
2) SCTP protocol tracker assumes that ICMP error messages contain the
checksum field, what results in packet drops. From Ying Xue.
3) Fix inconsistent handling of AH traffic from nf_tables.
4) Fix new bitmap set representation with big endian. Fix mismatches in
nf_tables due to incorrect big endian handling too. Both patches
from Liping Zhang.
5) Bridge netfilter doesn't honor maximum fragment size field, cap to
largest fragment seen. From Florian Westphal.
6) Fake conntrack entry needs to be aligned to 8 bytes since the 3 LSB
bits are now used to store the ctinfo. From Steven Rostedt.
7) Fix element comments with the bitmap set type. Revert the flush
field in the nft_set_iter structure, not required anymore after
fixing up element comments.
8) Missing error on invalid conntrack direction from nft_ct, also from
Liping Zhang.

Check that request has not been signaled before acquiring a reference to
the request for signaling later in the interrupt handler.
The loading of the cacheline (for request->fence.flags) should be "free"
when followed by the locked increment of the request->fence.refcount
(which then sets the cacheline to exclusive mode), i.e. the cost of
test_bit prior to an atomic_inc should be negligible. This should
benefit us when we have a pile of bare breadcrumbs (interrupted execbuf)
where we may get interrupts faster than we can get rid of the
intel_wait, or if the device is too slow to run the bottom-half between
interrupts.

We need to ensure that we always serialize updates to the bottom-half
using the breadcrumbs.irq_lock so that we don't race with a concurrent
interrupt handler. This is most important just prior to leaving the
waiter (when the intel_wait will be overwritten), so make sure we are
not the current bottom-half when skipping the irq locks.

Before walking the rbtree of waiters (marking them as complete and waking

missed waiter waking up and removing its intel_wait (which skips

The attached patch removes the flush of the offset map pages and does a

offset map in these routines as far as I can tell.

The tiadc_irq_h(int irq, void *private) function is handling FIFO
overruns by clearing flags, disabling and enabling the ADC to
recover.
If the ADC is running in continuous mode a FIFO overrun happens
regularly. If the disabling of the ADC happens concurrently with
a new conversion. It might happen that the enabling of the ADC
is ignored by the hardware. This stops the ADC permanently. No
more interrupts are triggered.
According to the AM335x Reference Manual (SPRUH73H October 2011 -
Revised April 2013 - Chapter 12.4 and 12.5) it is necessary to
check the ADC FSM bits in REG_ADCFSM before enabling the ADC
again. Because the disabling of the ADC is done right after the
current conversion has been finished.
To trigger this bug it is necessary to run the ADC in continuous
mode. The ADC values of all channels need to be read in an endless
loop. The bug appears within the first 6 hours (~5.4 million
handled FIFO overruns). The user space application will hang on
reading new values from the character device.

If ext4_convert_inline_data() was called on a directory with inline
data, the filesystem was left in an inconsistent state (as considered by
e2fsck) because the file size was not increased to cover the new block.
This happened because the inode was not marked dirty after i_disksize
was updated. Fix this by marking the inode dirty at the end of
ext4_finish_convert_inline_dir().
This bug was probably not noticed before because most users mark the
inode dirty afterwards for other reasons. But if userspace executed
FS_IOC_SET_ENCRYPTION_POLICY with invalid parameters, as exercised by
'kvm-xfstests -c adv generic/396', then the inode was never marked dirty
after updating i_disksize.

The only use of the ->prepare_context() fscrypt operation was to allow
ext4 to evict inline data from the inode before ->set_context().
However, there is no reason why this cannot be done as simply the first
step in ->set_context(), and in fact it makes more sense to do it that
way because then the policy modes and flags get validated before any
real work is done. Therefore, merge ext4_prepare_context() into
ext4_set_context(), and remove ->prepare_context().

Reviewing the result of what was just added for Kconfig, we made a poor
choice. It worked well for full kernel builds, but not so much for how
it would be deployed on a distro.
Here's the final result:
- lpfc will compile in NVME initiator and/or NVME target support based
on whether the kernel has the corresponding subsystem support.
Kconfig is not used to drive this specifically for lpfc.
- There is a module parameter, lpfc_enable_fc4_type, that indicates
whether the ports will do FCP-only or FCP & NVME (NVME-only not yet
possible due to dependency on fc transport). As FCP & NVME divvys up
exchange resources, and given NVME will not be often initially, the
default is changed to FCP only.

Filesystem encryption ostensibly supported revoking a keyring key that
had been used to "unlock" encrypted files, causing those files to become
"locked" again. This was, however, buggy for several reasons, the most
severe of which was that when key revocation happened to be detected for
an inode, its fscrypt_info was immediately freed, even while other
threads could be using it for encryption or decryption concurrently.
This could be exploited to crash the kernel or worse.
This patch fixes the use-after-free by removing the code which detects
the keyring key having been revoked, invalidated, or expired. Instead,
an encrypted inode that is "unlocked" now simply remains unlocked until
it is evicted from memory. Note that this is no worse than the case for
block device-level encryption, e.g. dm-crypt, and it still remains
possible for a privileged user to evict unused pages, inodes, and
dentries by running 'sync; echo 3 > /proc/sys/vm/drop_caches', or by
simply unmounting the filesystem. In fact, one of those actions was
already needed anyway for key revocation to work even somewhat sanely.
This change is not expected to break any applications.
In the future I'd like to implement a real API for fscrypt key
revocation that interacts sanely with ongoing filesystem operations ---
waiting for existing operations to complete and blocking new operations,
and invalidating and sanitizing key material and plaintext from the VFS
caches. But this is a hard problem, and for now this bug must be fixed.
This bug affected almost all versions of ext4, f2fs, and ubifs
encryption, and it was potentially reachable in any kernel configured
with encryption support (CONFIG_EXT4_ENCRYPTION=y,
CONFIG_EXT4_FS_ENCRYPTION=y, CONFIG_F2FS_FS_ENCRYPTION=y, or
CONFIG_UBIFS_FS_ENCRYPTION=y). Note that older kernels did not use the
shared fs/crypto/ code, but due to the potential security implications
of this bug, it may still be worthwhile to backport this fix to them.

Currently, intel_pstate_update_perf_limits() first converts the
policy minimum and maximum limits into percentages of the maximum
turbo frequency (rounding up to an integer) and then converts these
percentages to fractions (by using fixed-point arithmetic to divide
them by 100).
That introduces a rounding error unnecessarily, because the fractions
can be obtained by carrying out fixed-point divisions directly on the
input numbers.
Rework the computations in intel_pstate_hwp_set() to use fractions
instead of percentages (and drop redundant local variables from
there) and modify intel_pstate_update_perf_limits() to compute the
fractions directly and percentages out of them.
While at it, introduce percent_ext_fp() for converting percentages
to fractions (with extended number of fraction bits) and use it in
the computations.

that all paths that reach the error handler keep the device awake during
the hw reads. However, we need to extend that from the reset handler to
include the earlier capture routines.

Manual pointer manipulation is error prone. Let compiler calculate
right offsets for us in case we need to change ads layout.
v2: don't call it object (Chris)
v3: restyle offset assignments (Chris)
v4: stylistic reductions

Was getting the following error with allmodconfig:
ERROR: "__get_user_bad" [lib/test_user_copy.ko] undefined!
This was simply a missing break statement, causing an unwanted fall
through.

When building allmodconfig this warning shows.
fs/ocfs2/file.c: In function 'ocfs2_file_write_iter':

Applying the same patch logic that was done to the cmpxchg macro.

This adds the the devicetree binding for the Prefetch Resolve Gasket,
as found on i.MX6 QuadPlus.
The PRG is fairly simple in that it only has a configuration register
range and two clocks, one for the AHB slave port and one for the AXI
ports and the functional units.
The PRE connections need to be described in the DT, as the PRE<->PRG
assignment is a mix between fixed and muxable connections.

This adds support for the i.MX6 QuadPlus PRE units. Currently only
linear prefetch into SRAM is supported, other modes of operation
like the tiled-to-linear conversion will be added later.

The Prefetch Resolve Engine is a prefetch and tile resolve engine
which prefetches display data from DRAM to an internal SRAM region.
It has a single clock for configuration register access and the
functional units. A single shared interrupt is used for status and
error signaling.
The only external dependency is the SRAM region to use for the
prefetch double buffer.

The IPUv3 can read 8-bit alpha values from a separate plane buffer using
a companion IDMAC channel driven by the Alpha Transparency Controller
(ATC) for the graphics channels. The conditional read mechanism allows
to reduce memory bandwidth by skipping reads of color data for
completely transparent bursts.
