09663753bb tracing/ring-buffer: Clear all memory mapped CPU ring buffers on first recording
The events of a memory mapped ring buffer from the previous boot should
not be mixed in with events from the current boot. There's meta data that
is used to handle KASLR so that function names can be shown properly.

Also, since the timestamps of the previous boot have no meaning to the
timestamps of the current boot, having them intermingled in a buffer can
also cause confusion because there could possibly be events in the future.

When a trace is activated the meta data is reset so that the pointers of
are now processed for the new address space. The trace buffers are reset
when tracing starts for the first time. The problem here is that the reset
only happens on online CPUs. If a CPU is offline, it does not get reset.

To demonstrate the issue, a previous boot had tracing enabled in the boot
mapped ring buffer on reboot. On the following boot, tracing has not been
started yet so the function trace from the previous boot is still visible.

 # trace-cmd show -B boot_mapped -c 3 | tail

Now, if CPU 3 is taken offline, and tracing is started on the memory
mapped ring buffer, the events from the previous boot in the CPU 3 ring
buffer is not reset. Now those events are using the meta data from the
current boot and produces just hex values.

d610020f03 ubi: wl: Put source PEB into correct list if trying locking LEB failed
During wear-leveing work, the source PEB will be moved into scrub list
when source LEB cannot be locked in ubi_eba_copy_leb(), which is wrong
for non-scrub type source PEB. The problem could bring extra and
ineffective wear-leveing jobs, which makes more or less negative effects
for the life time of flash. Specifically, the process is divided 2 steps:
1. wear_leveling_worker // generate false scrub type PEB
     ubi_eba_copy_leb // MOVE_RETRY is returned
       leb_write_trylock // trylock failed
     scrubbing = 1;
     e1 is put into ubi->scrub
2. wear_leveling_worker // schedule false scrub type PEB for wl
     scrubbing = 1
     e1 = rb_entry(rb_first(&ubi->scrub))

The problem can be reproduced easily by running fsstress on a small
UBIFS partition(<64M, simulated by nandsim) for 5~10mins
(CONFIG_MTD_UBI_FASTMAP=y,CONFIG_MTD_UBI_WL_THRESHOLD=50). Following
message is shown:
 ubi0: scrubbed PEB 66 (LEB 0:10), data moved to PEB 165

Since scrub type source PEB has set variable scrubbing as '1', and
variable scrubbing is checked before variable keep, so the problem can
be fixed by setting keep variable as 1 directly if the source LEB cannot
be locked.

0b3144da31 USB: make single lock for all usb dynamic id lists
There are a number of places where we accidentally pass in a constant
structure to later cast it off to a dynamic one, and then attempt to
grab a lock on it, which is not a good idea.  To help resolve this, move
the dynamic id lock out of the dynamic id structure for the driver and
into one single lock for all USB dynamic ids.  As this lock should never
have any real contention (it's only every accessed when a device is
added or removed, which is always serialized) there should not be any
difference except for some memory savings.

Note, this just converts the existing use of the dynamic id lock to the
new static lock, there is one place that is accessing the dynamic id
list without grabbing the lock, that will be fixed up in a follow-on
change.

580bb355bc Revert: "ring-buffer: Do not have boot mapped buffers hook to CPU hotplug"
A crash happened when testing cpu hotplug with respect to the memory
mapped ring buffers. It was assumed that the hot plug code was adding a
per CPU buffer that was already created that caused the crash. The real
problem was due to ref counting and was fixed by commit 2cf9733891
("ring-buffer: Fix refcount setting of boot mapped buffers").

When a per CPU buffer is created, it will not be created again even with
CPU hotplug, so the fix to not use CPU hotplug was a red herring. In fact,
it caused only the boot CPU buffer to be created, leaving the other CPU
per CPU buffers disabled.

Revert that change as it was not the culprit of the fix it was intended to
be.

cb97b377a1 RDMA/bnxt_re: Refurbish CQ to NQ hash calculation
There are few use cases where CQ create and destroy
is seen before re-creating the CQ, this kind of use
case is disturbing the RR distribution and all the
active CQ getting mapped to only 2 NQ alternatively.

Fixing the CQ to NQ hash calculation by implementing
a quick load sorting mechanism under a mutex.

Using this, if the CQ was allocated and destroyed
before using it, the nq selecting algorithm still
obtains the least loaded CQ. Thus balancing the load
on NQs.

named "struct bnxt_re_nq_record" by keeping a pointer to in
the rdev structure. Allocate the memory for it dynamically.
This change is needed for subsequent patches in the series.

Also, removed the nq_task variable from rdev structure as it
is redundant and no longer used.

This change would help to reduce the size of the driver private
structure as well.
