Add NULL check for pdata and pdata->addr before the memcpy in

which occurs when the MPA private data pointer is NULL. Also
only copy pdata->size bytes in the memcpy to prevent reading

Current cxgb4 arm CQ logic ignores IB_CQ_REPORT_MISSED_EVENTS for
request completion notification on a CQ. Due to this ib_poll_handler()
assumes all events polled and avoids further iopoll scheduling.
This patch adds logic to cxgb4 ib_req_notify_cq() handler to check if
CQ is not empty and return accordingly. Based on the return value of
ib_req_notify_cq() handler, ib_poll_handler() will schedule a run of
iopoll handler.

The unwind logic for creating a user QP has a double vfree
of the non-shared receive queue when handling a "too many qps"
failure.
The code unwinds the mmmap info by decrementing a reference
count which will call rvt_release_mmap_info() which in turn
does the vfree() of the r_rq.wq. The unwind code then does
the same free.
Fix by guarding the vfree() with the same test that is done
in close and only do the vfree() if qp->ip is NULL.

Previously, J_KEY generation was based on the lower 16 bits
of the user's UID. While this works, it was not good enough
as a non-root user could collide with a root user given a
sufficiently large UID.
This patch attempt to improve the J_KEY generation by using
the following algorithm:
The 16 bit J_KEY space is partitioned into 3 separate spaces
reserved for different user classes:
* all users with administtor privileges (including 'root')
will use J_KEYs in the range of 0 to 31,
* all kernel protocols, which use KDETH packets will use
J_KEYs in the range of 32 to 63, and
* all other users will use J_KEYs in the range of 64 to
65535.
The above separation is aimed at preventing different user levels
from sending packets to each other and, additionally, separate
kernel protocols from all other types of users. The later is meant
to prevent the potential corruption of kernel memory by any other
type of user.

when a cat of the qp_stats is done:

The init functions do an implicit next which requires the rcu read lock

Fix for both drivers is to change the scope of the init function to only
do the allocation and the initialization of the just allocated iter.
The implict next is moved back into the respective start functions to fix

This is an entirely new driver instead of yet another set of patches
to sb_edac.c because:
1) Mapping from PCI devices to socket/memory controller is significantly
different. Skylake scatters devices on a socket across a number of
PCI buses.
2) There is an extra level of interleaving via the "mcroute" register
that would be a little messy to squeeze into the old driver.
3) Validation is getting too expensive. Changes to sb_edac need to
be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and
Knights Landing.

When building gccgo in userspace, errno.h gets parsed and the go include file
sysinfo.go is generated.
Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED
is defined later on in errno.h, this leads to go complaining that EREFUSED
isn't defined yet.
Fix this trivial problem by moving the define of EREFUSED down after
ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

The kernel test robot reported a usercopy failure in the new hardened
sanity checks, due to a page-crossing copy of the FPU state into the
task structure.
This happened because the kernel test robot was testing with SLOB, which
doesn't actually do the required book-keeping for slab allocations, and
as a result the hardening code didn't realize that the task struct
allocation was one single allocation - and the sanity checks fail.
Since SLOB doesn't even claim to support hardening (and you really
shouldn't use it), the straightforward solution is to just make the
usercopy hardening code depend on the allocator supporting it.
