====================
l2tp: remove unused code
Patch #1 removes the ref/deref mechanism that was originally used to
prevent ppp pseudowires from dropping their sockets. This mechanism
was error prone and isn't used anymore.
Patch #2 removes some module specific refcount debugging.
Patches #3 and #4 take care of some dead code.

With conversion to refcount_t, such manual debugging code doesn't make

The ->ref() and ->deref() callbacks are unused since PPP stopped using
them in ee40fb2e1eb5 ("l2tp: protect sock pointer of struct pppol2tp_session with RCU").
We can thus remove them from struct l2tp_session and drop the do_ref
parameter of l2tp_session_get*().

Commit 6f542ebeaee0 ("MIPS: Fix race on setting and getting
cpu_online_mask") effectively reverted commit 8f46cca1e6c06 ("MIPS: SMP:
Fix possibility of deadlock when bringing CPUs online") and thus has
reinstated the possibility of deadlock.
The commit was based on testing of kernel v4.4, where the CPU hotplug
core code issued a BUG() if the starting CPU is not marked online when
the boot CPU returns from __cpu_up. The commit fixes this race (in
v4.4), but re-introduces the deadlock situation.
As noted in the commit message, upstream differs in this area. Commit
8df3e07e7f21f ("cpu/hotplug: Let upcoming cpu bring itself fully up")
adds a completion event in the CPU hotplug core code, making this race
impossible. However, people were unhappy with relying on the core code
to do the right thing.
To address the issues both commits were trying to fix, add a second
completion event in the MIPS smp hotplug path. It removes the
possibility of a race, since the MIPS smp hotplug code now synchronises
both the boot and secondary CPUs before they return to the hotplug core
code. It also addresses the deadlock by ensuring that the secondary CPU
is not marked online before it's counters are synchronised.
This fix should also be backported to fix the race condition introduced
by the backport of commit 8f46cca1e6c06 ("MIPS: SMP: Fix possibility of
deadlock when bringing CPUs online"), through really that race only
existed before commit 8df3e07e7f21f ("cpu/hotplug: Let upcoming cpu
bring itself fully up").

single nouveau regression fix.
* 'linux-4.14' of git://github.com/skeggsb/linux:
drm/nouveau/kms/nv50: use the correct state for base channel notifier setup
|
|
The default CM target field in the GCR_BASE register is encoded with 0
meaning memory & 1 being reserved. However the definitions we use for
those bits effectively get these two values backwards - likely because
they were copied from the definitions for the CM regions where the
target is encoded differently. This results in use setting up GCR_BASE
with the reserved target value by default, rather than targeting memory
as intended. Although we currently seem to get away with this it's not a
great idea to rely upon.
Fix this by changing our macros to match the documentated target values.
The incorrect encoding became used as of commit 9f98f3dd0c51 ("MIPS: Add
generic CM probe & access code") in the Linux v3.15 cycle, and was
likely carried forwards from older but unused code introduced by
commit 39b8d5254246 ("[MIPS] Add support for MIPS CMP platform.") in the
v2.6.26 cycle.

Commit e83f7e02af50c ("MIPS: CPS: Have asm/mips-cps.h include CM & CPC
headers") adds a #error to arch/mips/include/asm/mips-cpc.h if it is
included directly. While this commit replaced almost all direct includes
of mips-cm.h and mips-cpc.h, 2 remain.
With some defconfigs, mips-cps.h is indirectly included before
mips-cpc.h, but in others this results in compilation errors:
In file included from arch/mips/generic/init.c:23:0:
./arch/mips/include/asm/mips-cpc.h:12:3: error: #error Please include

# error Please include asm/mips-cps.h rather than asm/mips-cpc.h
In both cases, fix this by including mips-cps.h instead.

Commit 9fef68686317b ("MIPS: Make SAVE_SOME more standard") made several
changes to the order in which registers are saved in the SAVE_SOME
macro, used by exception handlers to save the processor state. In
particular, it removed the
move k1, sp
in the delay slot of the branch testing if the processor is already in
kernel mode. This is replaced later in the macro by a
move k0, sp
When CONFIG_EVA is disabled, this instruction actually appears in the
delay slot of the branch. However, when CONFIG_EVA is enabled, instead
the RPS workaround of
MFC0 k0, CP0_ENTRYHI
appears in the delay slot. This results in k0 not containing the stack
pointer, but some unrelated value, which is then saved to the kernel
stack. On exit from the exception, this bogus value is restored to the
stack pointer, resulting in an OOPS.
Fix this by moving the save of SP in k0 explicitly in the delay slot of
the branch, outside of the CONFIG_EVA section, restoring the expected
instruction ordering when CONFIG_EVA is active.

MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:
- Have 10 or more patches in mainline authored using an @imgtec.com
email address, or any patches dated within the past year.
- Are still with Imagination but leaving as part of the MIPS business
unit, as determined from an internal email address list.
- Haven't already updated their email address (ie. JamesH) or expressed
a desire to be excluded (ie. Maciej).
- Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
myself.
New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list. An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.
Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

Currently the mlx5e driver has multiple groups of stats, each group is
used for different purposes and it may depend on hardware capabilities
or not. The problem with the current implementation is that there is no
clear API to create a new group of stats.
This change define a new API to create a group of stats and simplifies
the way of handling them by defining a new struct "mlx5e_stats_grp" which
have the following three function pointers:
- get_num_stats() - return the number of counters in the group.
- fill_strings() - fill counters strings within the group.
- fill_stats() - fill counters values within the group.
The above function pointers are used within the ethtool callbaks while
calling "ethtool -S" from userspace. This change also switch the SW
group to use the new API.

By default, sparse assumes a 64bit machine when compiled on x86-64
and 32bit when compiled on anything else.
This can of course create all sort of problems, like issuing false
warnings like: 'constant ... is so big it is unsigned long long'
or 'shift too big (32) for type unsigned long' when the architecture
is 64bit while sparse was compiled on a 32bit machine, or worse,
to not emit legitimate warnings in the reverse situation.
Fix this by passing to sparse the appropriate -m32/-m64 flag.

This patch enables tc-flower based hardware offloads. tc flower
filter provided by the kernel is configured as driver specific
cloud filter. The patch implements functions and admin queue
commands needed to support cloud filters in the driver and
adds cloud filters to configure these tc-flower filters.
The classification function of the filter is to direct matched
packets to a traffic class. The hardware traffic class is set
based on the the classid reserved in the range :ffe0 - :ffef.
Match Dst MAC and route to TC0:
prio 1 flower dst_mac 3c:fd:fe:a0:d6:70 skip_sw\
hw_tc 1
Match Dst IPv4,Dst Port and route to TC1:
prio 2 flower dst_ip 192.168.3.5/32\
ip_proto udp dst_port 25 skip_sw\
hw_tc 2
Match Dst IPv6,Dst Port and route to TC1:
prio 3 flower dst_ip fe8::200:1\
ip_proto udp dst_port 66 skip_sw\
hw_tc 2
Delete tc flower filter:
Example:
Flow Director Sideband is disabled while configuring cloud filters
via tc-flower and until any cloud filter exists.
Unsupported matches when cloud filters are added using enhanced
big buffer cloud filter mode of underlying switch include:
1. source port and source IP
2. Combined MAC address and IP fields.
3. Not specifying L4 port
These filter matches can however be used to redirect traffic to
the main VSI (tc 0) which does not require the enhanced big buffer
cloud filter support.

Add mapping of TCs with the seids of the channel VSIs. TC0
will be mapped to the main VSI seid and all other TCs are
mapped to the seid of the corresponding channel VSI.

This patch offloads the classid to hardware and uses the classid
reserved in the range :ffe0 - :ffef to identify hardware traffic
classes reported via dev->num_tc.
tcf_result structure contains the class ID of the class to which
the packet belongs and is offloaded to hardware via flower filter.
A new helper function is introduced to represent HW traffic
classes 0 through 15 using the reserved classid values :ffe0 - :ffef.

This reverts commit 11f29003d6376fb123b7c3779dba49bb56fb0815.
I am reverting this as I am fairly certain this can result in a memory leak
when combined with the current page recycling scheme. Specifically we end
up attempting to allocate fewer buffers than we recycled and this results
in us rewinding the next to alloc pointer which leads to leaks when we
overwrite the rx_buffer_info when processing the next frame.

Whether or not there are vectors_left, we only need to redistribute
our vectors if we didn't get as many as we requested. With the current
check, the code will try to redistribute even if we did in fact get all
the vectors we requested - this can happen when we have more CPUs than
we do vectors. This restores an earlier check to be sure we only
redistribute if we didn't get the full count we requested.

This reverts commit 0cc2b4e5a020 (PM / QoS: Fix device resume latency PM
QoS) as it introduced regressions on multiple systems and the fix-up
in commit 2a9a86d5c813 (PM / QoS: Fix default runtime_pm device resume
latency) does not address all of them.
The original problem that commit 0cc2b4e5a020 was attempting to fix
will be addressed later.

A cleanup of the PM code left an incorrect #ifdef in place, leading
to a harmless build warning:
drivers/net/ethernet/intel/i40e/i40e_main.c:12223:12: error: 'i40e_resume' defined but not used [-Werror=unused-function]
drivers/net/ethernet/intel/i40e/i40e_main.c:12185:12: error: 'i40e_suspend' defined but not used [-Werror=unused-function]
It's easier to use __maybe_unused attributes here, since you
can't pick the wrong one.

On error, kthread_create() returns an errno-encoded pointer, not NULL.
The routine qla2x00_probe_one() detects the error case and jumps to
probe_failed, but has already assigned the return value from
kthread_create() to ha->dpc_thread. Then probe_failed checks to see if
ha->dpc_thread is not NULL before doing cleanup on it. Since in the
error case this is also not NULL, it ends up trying to access an invalid
task pointer.
Solution is to assign NULL to ha->dpc_thread in the error path to avoid
kthread cleanup in that case.
