When falling back to an allocation from the HW header cache, check if
the skb is eligible for using memory reserves.
This only makes a difference if the cache is empty and needs to be
refilled.

There is measurable performance impact in some synthetic tests due to
commit 6d390e4b5d48 (locks: fix a potential use-after-free problem when
wakeup a waiter). Fix the race condition instead by clearing the
fl_blocker pointer after the wake_up, using explicit acquire/release
semantics.
This does mean that we can no longer use the clearing of fl_blocker as
the wait condition, so switch the waiters over to checking whether the
fl_blocked_member list_head is empty.

(uint16_t) st_shndx is limited to 65535(i.e. SHN_XINDEX) so sym_get_data() gets
wrong section index by st_shndx if requested symbol contains extended section
index that is more than 65535. In this case, we need to get proper section index
by .symtab_shndx section.
Module.symvers generated by building kernel with "-ffunction-sections -fdata-sections"

This is just a cleanup addition to Jann's fix to properly update the
transaction ID for the slub slowpath in commit fd4d9c7d0c71 ("mm: slub:
add missing TID bump..").
The transaction ID is what protects us against any concurrent accesses,
but we should really also make sure to make the 'freelist' comparison
itself always use the same freelist value that we then used as the new
next free pointer.
Jann points out that if we do all of this carefully, we could skip the
transaction ID update for all the paths that only remove entries from
the lists, and only update the TID when adding entries (to avoid the ABA
issue with cmpxchg and list handling re-adding a previously seen value).
But this patch just does the "make sure to cmpxchg the same value we
used" rather than then try to be clever.

When kmem_cache_alloc_bulk() attempts to allocate N objects from a percpu
freelist of length M, and N > M > 0, it will first remove the M elements
from the percpu freelist, then call ___slab_alloc() to allocate the next
element and repopulate the percpu freelist. ___slab_alloc() can re-enable
IRQs via allocate_slab(), so the TID must be bumped before ___slab_alloc()
to properly commit the freelist head change.
Fix it by unconditionally bumping c->tid when entering the slowpath.

Commit 77654350306a ("take compat TIOC[SG]SERIAL treatment into
tty_compat_ioctl()") changed the compat version of TIOCGSERIAL to start
checking for the presence of the ->set_serial function pointer rather
than ->get_serial. This appears to be a copy-and-paste error, since
->get_serial is the function pointer that is called as well as the
pointer that is checked by the non-compat version of TIOCGSERIAL.
Fix this by checking the correct function pointer.

As Hash based reo destination selection is configured,
the decapped packets reach different reo destintion rings
based on the destintaion ring selected for the computed hash (based on
the 5-tuple {ip src/ip dst/src port/dst port/protocol}) by hw and
as configured by driver.
Hence the current implementation of amsdu list based processing after all
the subframes of amsdu are received (since all msdu's for a pdev are
received in same reo dest ring), is not applicable here and hence is
replaced with per msdu based handling as these subframes
can be received in different reo dest rings.
Also, as some of the rx descriptor fields might be valid only for the
first msdu (for ex. received 80211 header, encryption type, etc),
it might not be useful now as we cannot sync between different
subframes received in different rings. Hence do not rely on those
fields and replace them with fieds valid only on per msdu descriptors.
Also cache other details such as encryption type for a peer so that
it can be reused when a packet is received from it.

The 4 reo destination rings are selected by the HW based on the

Before dumping tx_stats proper validation was not been taken care of.
Due to which we were encountering null pointer dereference(kernel panic).
This scenario will arise when a station is getting disconnected and
we are changing the STA state by ath11k_mac_op_sta_state and assigning
tx_stats as NULL and after this the mac80211 will destroy the
debugfs entry from where we are trying to read the stats.
If anyone tries to dump tx_stats for that STA in between setting
tx_stats to NULL and debugfs file removal without checking the NULL
value it will run into a NULL pointer exception.
Proceeding with the analysis of "ARM Kernel Panic".
The APSS crash happened due to OOPS on CPU 3.

never seen one) BT 4.0 chips will fail to do both at once. Even this is
ok since the command that will fail will be the second one, and thus the

net: bridge: vlan options: add support for tunnel mapping
In order to bring the new vlan API on par with the old one and be able
to completely migrate to the new one we need to support vlan tunnel mapping
and statistics. This patch-set takes care of the former by making it a
vlan option. There are two notable issues to deal with:
- vlan range to tunnel range mapping
* The tunnel ids are globally unique for the vlan code and a vlan can
be mapped to one tunnel, so the old API took care of ranges by
taking the starting tunnel id value and incrementally mapping
vlan id(i) -> tunnel id(i). This set takes the same approach and
uses one new attribute - BRIDGE_VLANDB_ENTRY_TUNNEL_ID. If used
with a vlan range then it's the starting tunnel id to map.
- tunnel mapping removal
* Since there are no reserved/special tunnel ids defined, we can't
encode mapping removal within the new attribute, in order to be
able to remove a mapping we add a vlan flag which makes the new
tunnel option remove the mapping
The rest is pretty straight-forward, in fact we directly re-use the old
code for manipulating tunnels by just mapping the command (set/del). In
order to be able to keep detecting vlan ranges we check that the current
vlan has a tunnel and it's extending the current vlan range end's tunnel
id.

This patch adds support for manipulating vlan/tunnel mappings. The
tunnel ids are globally unique and are one per-vlan. There were two
trickier issues - first in order to support vlan ranges we have to
compute the current tunnel id in the following way:
- base tunnel id (attr) + current vlan id - starting vlan id
This is in line how the old API does vlan/tunnel mapping with ranges. We
already have the vlan range present, so it's redundant to add another
attribute for the tunnel range end. It's simply base tunnel id + vlan
range. And second to support removing mappings we need an out-of-band way
to tell the option manipulating function because there are no
special/reserved tunnel id values, so we use a vlan flag to denote the
operation is tunnel mapping removal.

Add a new option - BRIDGE_VLANDB_ENTRY_TUNNEL_ID which is used to dump
the tunnel id mapping. Since they're unique per vlan they can enter a
vlan range if they're consecutive, thus we can calculate the tunnel id
range map simply as: vlan range end id - vlan range start id. The
starting point is the tunnel id in BRIDGE_VLANDB_ENTRY_TUNNEL_ID. This
is similar to how the tunnel entries can be created in a range via the
old API (a vlan range maps to a tunnel range).

The vlan tunnel code changes vlan options, it shouldn't touch port or
bridge options so we can constify the port argument. This would later help
us to re-use these functions from the vlan options code.

It is more appropriate name as it shows the intent of why we need to
check the options' state. It also allows us to give meaning to the two
arguments of the function: the first is the current vlan (v_curr) being
checked if it could enter the range ending in the second one (range_end).

====================
net: stmmac: 100GB Enterprise MAC support
Adds the support for Enterprise MAC IP version which allows operating
speeds up to 100GB.
Patch 1/4, adds the support in XPCS for XLGMII interface that is used in
this kind of Enterprise MAC IPs.
Patch 2/4, adds the XLGMII interface support in stmmac.
Patch 3/4, adds the HW specific support for Enterprise MAC.
We end in patch 4/4, by updating stmmac documentation to mention the
support for this new IP version.

Adds the support for Enterprise MAC IP version which is very similar to
XGMAC. It's so similar that we just need to check the device id and add
new speeds definitions and some minor callbacks.

last_keep_alive_jiffies is updated in probe and when a keep-alive
event is received. In case the driver times-out on a keep-alive event,
it has high chances of continuously timing-out on keep-alive events.
This is because when the driver recovers from the keep-alive-timeout reset
the value of last_keep_alive_jiffies is very old, and if a keep-alive
event is not received before the next timer expires, the value of
last_keep_alive_jiffies will cause another keep-alive-timeout reset
and so forth in a loop.
Solution:
Update last_keep_alive_jiffies whenever the device is restored after
reset.
