The current default for async hw receive queues is 1, which presents
issues under heavy load as number of queues influence the available
async receive buffer limits.
Raise the default to the either the current hw limit (16) or the number

Revise the attribute definition for mrq to better reflect what we do for
hw queues. E.g. 0 means default to optimal (# of cpus), non-zero
specifies a specific limit. Before this change, mrq=0 meant target mode
was disabled. As 0 now has a different meaning, rework the if tests to

Hardware queues are a fast staging area to push commands into the
adapter. The adapter should drain them extremely quickly. However,
under heavy io load, the host cpu is pushing commands faster than the
drain rate of the adapter causing the driver to resource busy commands.
Enlarge the hardware queue (wq & cq) to support a larger number of queue
entries (4x the prior size) before backpressure. Enlarging the queue
requires larger contiguous buffers (16k) per logical page for the
hardware. This changed calling sequences that were expecting 4K page
sizes that now must pass a parameter with the page sizes. It also
required use of a new version of an adapter command that can vary the
page size values.

bfa_aen_entry_s is passed through a netlink socket that can be read by
either 32-bit or 64-bit processes, but the data format is different
between the two on current implementations.
Originally, this was using a 'struct timeval', which also suffers from
getting redefined with a new libc implementation.
With this patch, the layout gets fixed to having two 64-bit members for
the time, making it the same on 32-bit kernels and 64-bit kernels
running either compat or native user space including x32.
Provided that the new header file gets used to recompile any 32-bit
application binaries, this will fix running those on a 64-bit kernel
(with or without this patch) e.g. in a container environment, and it
will make binaries work that will be built against a future 32-bit glibc
that uses a 64-bit time_t, and avoid the y2038 overflow there.
However, this also breaks compatibility with any existing 32-bit binary
running on a native 32-bit kernel, those must be recompiled against the
new header, which in turn makes them incompatible with older kernels
unless the same change gets applied there.
Obviously this patch should only be applied when the benefits outweigh
the possible breakage. I'm posting it under the assumption that there
are no open-source tools using the netlink interface, and that users of
the binaries provided by qlogic for SLES10/11 and RHEL5/6 are not
actually being used on new future systems with 32-bit x86 kernels.

bfa_aen_entry_s is passed to user space in a netlink message, but is
defined using a 'struct timeval' and an 'enum' that are not only
different between architectures, but also between 32-bit user space and
64-bit kernels they may run on, as well as depending on the particular C
library that defines timeval.
This changes the in-kernel definition to no longer use the timeval type
directly but instead use two open-coded 'unsigned long' members. This
keeps the existing ABI, but making the variable unsigned also helps make
it work after y2038, until it overflows in 2106.
Since the macro becomes overly complex at this point, I'm changing it to
an inline function for readability.
I'm not changing the 32-bit user-space ABI at this point, to keep the
changes separate, I deally this would be defined using the same binary
layout for all architectures.

0xffffffff80000000 in y2038 and produce wrong results.

bfa_get_log_time() without that problem, so we can simply remove the
former use ktime_get_real_seconds() instead.

* GICv4 Support for KVM/ARM
All ARM patches were in next-20171113. I have postponed most x86 fixes
to 4.15-rc2 and UMIP to 4.16, but there are fixes that would be good to
have already in 4.15-rc1:
* re-introduce support for CPUs without virtual NMI (cc stable)
and allow testing of KVM without virtual NMI on available CPUs
* fix long-standing performance issues with assigned devices on AMD
(cc stable)

A small batch of fixes, about 50% tagged for stable and the rest for recently
merged code.
There's one more fix for the >128T handling on hash. Once a process had
requested a single mmap above 128T we would then always search above 128T. The
correct behaviour is to consider the hint address in isolation for each mmap
request.
Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in VAS, a fix
for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly identify P9 DD2.1 but in
code that is currently not used by default.

Pull SCSI target updates from Nicholas Bellinger:
"This series is predominantly bug-fixes, with a few small improvements
that have been outstanding over the last release cycle.
As usual, the associated bug-fixes have CC' tags for stable.
Also, things have been particularly quiet wrt new developments the
last months, with most folks continuing to focus on stability atop 4.x
stable kernels for their respective production configurations.
Also at this point, the stable trees have been synced up with
mainline. This will continue to be a priority, as production users
tend to run exclusively atop stable kernels, a few releases behind
mainline.
The highlights include:
- Fix PR PREEMPT_AND_ABORT null pointer dereference regression in
v4.11+ (tangwenji)
- Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu)
- Add netlink command reply supported option for each device (Kenjiro
Nakayama)
- cxgbit: Abort the TCP connection in case of data out timeout (Varun
Prakash)
- Fix PR/ALUA file path truncation (David Disseldorp)
- Fix double se_cmd completion during ->cmd_time_out (Mike Christie)
- Fix QUEUE_FULL + SCSI task attribute handling in 4.1+ (Bryant Ly +
nab)
- Fix quiese during transport_write_pending_qf endless loop (nab)
- Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK in 3.14+

afs_mkdir(), afs_create(), afs_link() and afs_symlink() all need to drop
the target dentry if a signal causes the operation to be killed immediately
before we try to contact the server.
Signed-off-by: David Howells <dhowells@redhat.com>
Fix some of dentry handling in AFS directory ops:
(1) Do d_drop() on the new_dentry before assigning a new inode to it in
afs_vnode_new_inode(). It's fine to do this before calling afs_iget()
because the operation has taken place on the server.
(2) Replace d_instantiate()/d_rehash() with d_add().
(3) Don't d_drop() the new_dentry in afs_rename() on error.
Also fix afs_link() and afs_rename() to call key_put() on all error paths
where the key is taken.
