While debugging setkey issues, the following warnings were found while
trying to reinsert the caam module. Fix this by avoiding the duplicated
cleanup in the probe path after caam_remove(), which has already cleaned
up the resources.

Threaded interrupts can perform the function of the tasklet, and much
more safely too - without races when trying to take the tasklet and
interrupt down on device removal.
With the old code, there is a window where we call tasklet_kill(). If
the interrupt handler happens to be running on a different CPU, and
subsequently calls tasklet_schedule(), the tasklet will be re-scheduled
for execution.
Switching to a hardirq/threadirq combination implementation avoids this,
and it also means generic code deals with the teardown sequencing of the
threaded and non-threaded parts.

Strictly, dma_map_sg() may coalesce SG entries, but in practise on iMX
hardware, this will never happen. However, dma_map_sg() can fail, and
we completely fail to check its return value. So, fix this properly.
Arrange the code to map the scatterlist early, so we know how many
scatter table entries to allocate, and then fill them in. This allows
us to keep relatively simple error cleanup paths.

Since the extended descriptor includes the hardware descriptor, and the

at the very end of the extended descriptor. This allows us to get rid

caamhash contains this weird code:
src_nents = sg_count(req->src, req->nbytes);
dma_map_sg(jrdev, req->src, src_nents ? : 1, DMA_TO_DEVICE);
...
edesc->src_nents = src_nents;
sg_count() returns zero when sg_nents_for_len() returns zero or one.
This means we don't need to use a hardware scatterlist. However,
setting src_nents to zero causes problems when we unmap:
if (edesc->src_nents)
dma_unmap_sg_chained(dev, req->src, edesc->src_nents,
DMA_TO_DEVICE, edesc->chained);
as zero here means that we have no entries to unmap. This causes us
to leak DMA mappings, where we map one scatterlist entry and then
fail to unmap it.
This can be fixed in two ways: either by writing the number of entries
that were requested of dma_map_sg(), or by reworking the "no SG
required" case.
We adopt the re-work solution here - we replace sg_count() with
sg_nents_for_len(), so src_nents now contains the real number of
scatterlist entries, and we then change the test for using the
hardware scatterlist to src_nents > 1 rather than just non-zero.
This change passes my sshd, openssl tests hashing /bin and tcrypt
tests.

Since 6de62f15b581 ("crypto: algif_hash - Require setkey before
accept(2)"), the AF_ALG interface requires userspace to provide a key
to any algorithm that has a setkey method. However, the non-HMAC
algorithms are not keyed, so setting a key is unnecessary.
Fix this by removing the setkey method from the non-keyed hash
algorithms.

To be able to generate shared descriptors for AEAD, the authentication size
needs to be known. However, there is no imposed order of calling .setkey,
.setauthsize callbacks.
Thus, in case authentication size is not known at .setkey time, defer it
until .setauthsize is called.
The authsize != 0 check was incorrectly removed when converting the driver
to the new AEAD interface.

There are a few things missed by the conversion to the
new AEAD interface:
1 - echainiv(authenc) encrypt shared descriptor
The shared descriptor is incorrect: due to the order of operations,
at some point in time MATH3 register is being overwritten.
2 - buffer used for echainiv(authenc) encrypt shared descriptor
Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually
exclusive and thus use the same buffer in context state: sh_desc_enc.
However, there's one place missed by s/sh_desc_givenc/sh_desc_enc,
leading to errors when echainiv(authenc(...)) algorithms are used:
DECO: desc idx 14: Header Error. Invalid length or parity, or
certain other problems.
While here, also fix a typo: dma_mapping_error() is checking
for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

risk of conflict was reduced. I just rebased the series on top of
current master, and no new ->bi_rw usage has snuck in"

Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.
No intended functional changes in this commit.

Commit abf545484d31 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.
Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

Pull binfmt_misc update from James Bottomley:
"This update is to allow architecture emulation containers to function
such that the emulation binary can be housed outside the container
itself. The container and fs parts both have acks from relevant
experts.
To use the new feature you have to add an F option to your binfmt_misc
configuration"
From the docs:
"The usual behaviour of binfmt_misc is to spawn the binary lazily when
the misc format file is invoked. However, this doesn't work very well
in the face of mount namespaces and changeroots, so the F mode opens
the binary as soon as the emulation is installed and uses the opened
image to spawn the emulator, meaning it is always available once
installed, regardless of how the environment changes"

In most cases, EPERM is returned on immutable inode, and there're only a
few places returning EACCES. I noticed this when running LTP on
overlayfs, setxattr03 failed due to unexpected EACCES on immutable
inode.
So converting all EACCES to EPERM on immutable inode.

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull more xfs updates from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle, and
contains the new reverse block mapping feature for XFS.
Reverse mapping allows us to track the owner of a specific block on
disk precisely. It is implemented as a set of btrees (one per
allocation group) that track the owners of allocated extents.
Effectively it is a "used space tree" that is updated when we allocate
or free extents. i.e. it is coherent with the free space btrees we
already maintain and never overlaps with them.
This reverse mapping infrastructure is the building block of several
upcoming features - reflink, copy-on-write data, dedupe, online
metadata and data scrubbing, highly accurate bad sector/data loss
reporting to users, and significantly improved reconstruction of
damaged and corrupted filesystems. There's a lot of new stuff coming
along in the next couple of cycles,a nd it all builds in the rmap
infrastructure.
As such, it's a huge chunk of new code with new on-disk format
features and internal infrastructure. It warns at mount time as an
experimental feature and that it may eat data (as we do with all new
on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time kernel
with this code in it is released.
The new rmap enabled code regresses 3 xfstests - all are ENOSPC
related corner cases, one of which Darrick posted a fix for a few
hours ago. The other two are fixed by infrastructure that is part of
the upcoming reflink patchset. This new ENOSPC infrastructure
requires a on-disk format tweak required to keep mount times in
check - we need to keep an on-disk count of allocated rmapbt blocks so
we don't have to scan the entire btrees at mount time to count them.
This is currently being tested and will be part of the fixes sent in
the next week or two so users will not be exposed to this change"
