Format specifier %p can leak kernel addresses while not valuing the
kptr_restrict system settings. When kptr_restrict is set to (1), kernel
pointers printed using the %pK format specifier will be replaced with
Zeros. Debugging Note : &pK prints only Zeros as address. If you need
actual address information, write 0 to kptr_restrict.

This patch adds support for recognition of ARM-USB-TINY(H) devices which
are almost identical to ARM-USB-OCD(H) but lacking separate barrel jack
and serial console.
By suggestion from Johan Hovold it is possible to replace
ftdi_jtag_quirk with a bit more generic construction. Since all
Olimex-ARM debuggers has exactly two ports, we could safely always use
only second port within the debugger family.

The page table dump code doesn't know about huge pages, so currently
it crashes (or walks random memory, usually leading to a crash), if it
finds a huge page. On Book3S we only see huge pages in the Linux page
tables when we're using the P9 Radix MMU.
Teaching the code to properly handle huge pages is a bit more involved,

Code review of NVMEI's FC_PORT_ROLE_NVME_DISCOVERY looked wrong.
Discussions with storage architecture team clarified NVMEI's audit of
the PRLI response port roles. Following up discussion with code review
showed a few minor corrections were required - especially in
anticipation of NVME auto discovery.
During PRLI, NVMEI should sent prli_init - which it it does. NVMET
should send prli_tgt and prli_disc - which it does. When NVMEI receives
a PRLI Response now, it audits the incoming target bits and stores the
attributes in the corresponding NDLP. Later, when NVMEI registers the
NVME rport, it uses the stored ndlp attributes to set the rport
port_roles correctly.

Too many work items being processed in IRQ context take a lot of CPU
time and cause problems.
With a recent change, we get out of the ISR after hitting entry_repost
work items on a queue. However, the actual values for entry repost are
still high. EQ is 128 and CQ is 128, this could translate into
processing 128 * 128 (16384) work items under IRQ context.
Set entry_repost in the actual queue creation routine now. Limit EQ
repost to 8 and CQ repost to 64 to further limit the amount of time
spent in the IRQ.
Fix fof IRQ routines as well.

When unloading and reloading the driver, the driver fails to recreate
the lpfc root inode in the debugfs tree.
The driver is incorrectly removing the lpfc root inode in
lpfc_debugfs_terminate in the first driver instance that unloads and
then sets the lpfc_debugfs_root global parameter to NULL. When the
final driver instance unloads, the debugfs calls quietly ignore the
remove on a NULL pointer. The bug is that the debugfs_remove call
returns void so the driver doesn't know to correctly set the global
parameter to NULL.
Base the debugfs_remove of the lpfc_debugfs_root parameter on
lpfc_debugfs_hba_count because this parameter tracks the fnX instance
tracked per driver instance.

Currently IO resources are mapped 1 to 1 with RQ buffers posted
Added logic to separate RQE buffers from IO op resources
(sgl/iocbq/context). During initialization, the driver will determine
how many SGLs it will allocate for NVMET (based on what the firmware
reports) and associate a NVMET IOCBq and NVMET context structure with
each one.
Now that hdr/data buffers are immediately reposted back to the RQ, 512
RQEs for each MRQ is sufficient. Also, since NVMET data buffers are now
128 bytes, lpfc_nvmet_mrq_post is not necessary anymore as we will
always post the max (512) buffers per NVMET MRQ.

During driver boot, a latency in the NVMET driver side causes the
incoming NVMEI PRLI to get rejected by the NVMET driver. When this
happens, the NVMEI driver runs out of PRLI retries. Bouncing the link
does not fix the situation.
If the NVMEI driver decides, on PRLI completion failures, to retry the
PRLI, always decrement the fc4_prli_sent counter. This allows the PRLI
completion to resolve to UNMAPPED when NVMET rejects the PRLI.

Commit cae9ff036eea effectively disabled the drm poll_helper by checking
the wrong flag to see if the driver should enable the poll or not:
mode_config.poll_enabled is only set to true by poll_init and it is not
indicating if the poll is enabled or not.
nouveau_display_create() will initialize the poll and going to disable it
right away. After poll_init() the mode_config.poll_enabled will be true,
but the poll itself is disabled.
To avoid the race caused by calling the poll_enable() from different paths,
this patch will enable the poll from one place, in the
nouveau_display_hpd_work().
In case the pm_runtime is disabled we will enable the poll in
nouveau_drm_load() once.

There were a number of handwaving complaints that one could "possibly"
use inode numbers and extent maps to fingerprint a filesystem hosting
multiple containers and somehow use the information to guess at the
contents of other containers and attack them. Despite the total lack of
any demonstration that this is actually possible, it's easier to
restrict access now and broaden it later, so use the rmapbt fsmap
backends only if the caller has CAP_SYS_ADMIN. Unprivileged users will

To some extent this is the expected effect of the patch, and the
additional CPU utilization is only visible when running the
benchmarks. However, halving the threshold also halves the extra
CPU utilization (from +30-130% to +20-70%) and has no negative

Also, change the type of the variable "count" in the function
"__evict_old_buffers" to unsigned long. The assignment
"count = c->n_buffers[LIST_CLEAN] + c->n_buffers[LIST_DIRTY];"
could result in unsigned long to unsigned overflow and that could result
in buffers not being freed when they should.
While at it, avoid division in get_retain_buffers(). Division is slow,
we can change it to shift because we have precalculated the log2 of

In general, rtnetlink dumps do not anticipate failure to dump a single
object (e.g., link or route) on a single pass. As both route and link
objects have grown via more attributes, that is no longer a given.
netlink dumps can handle a failure if the dump function returns an
error; specifically, netlink_dump adds the return code to the response
if it is <= 0 so userspace is notified of the failure. The missing
piece is the rtnetlink dump functions returning the error.
Fix route and link dump functions to return the errors if no object is
added to an skb (detected by skb->len != 0). IPv6 route dumps
(rt6_dump_route) already return the error; this patch updates IPv4 and
link dumps. Other dump functions may need to be ajusted as well.

tcp_ack() can call tcp_fragment() which may dededuct the
value tp->fackets_out when MSS changes. When prior_fackets
is larger than tp->fackets_out, tcp_clean_rtx_queue() can
invoke tcp_update_reordering() with negative values. This
results in absurd tp->reodering values higher than
sysctl_tcp_max_reordering.
Note that tcp_update_reordering indeeds sets tp->reordering
to min(sysctl_tcp_max_reordering, metric), but because
the comparison is signed, a negative metric always wins.
