"During testing Sedat Dilek hit a "suspicious RCU usage" splat that
pointed out a real bug. During suspend and resume the tlb_flush
tracepoint is called when the CPU is going offline. As the CPU has
been noted as offline, RCU is ignoring that CPU, which means that it
can not use RCU protected locks. When tracepoints are activated, they
require RCU locking, and if RCU is ignoring a CPU that runs a
tracepoint, there is a chance that the tracepoint could cause
corruption.
The solution was to change the tracepoint into a
TRACE_EVENT_CONDITION() which allows us to check a condition to
determine if the tracepoint should be called or not. If the condition
is not met, the rcu protected code will not be executed. By adding
the condition "cpu_online(smp_processor_id())", this will prevent the
RCU protected code from being executed if the CPU is marked offline.
After adding this, another bug was discovered. As RCU checks rcu
callers, if a rcu call is not done, there is no check (obviously). We
found that tracepoints could be added in RCU ignored locations and not
have lockdep complain until the tracepoint is activated. This missed
places where tracepoints were added in places they should not have
been. To fix this, code was added in 3.18 that if lockdep is enabled,
any tracepoint will still call the rcu checks even if the tracepoint
is not enabled. The bug here, is that the check does not take the
CONDITION into account. As the condition may prevent tracepoints from
being activated in RCU ignored areas (as the one patch does), we get
false positives when we enable lockdep and hit a tracepoint that the
condition prevents it from being called in a RCU ignored location.
The fix for this is to add the CONDITION to the rcu checks, even if
the tracepoint is not enabled"

tracing: Add condition check to RCU lockdep checks
The trace_tlb_flush() tracepoint can be called when a CPU is going offline.
When a CPU is offline, RCU is no longer watching that CPU and since the
tracepoint is protected by RCU, it must not be called. To prevent the
tlb_flush tracepoint from being called when the CPU is offline, it was
converted to a TRACE_EVENT_CONDITION where the condition checks if the
CPU is online before calling the tracepoint.
Unfortunately, this was not enough to stop lockdep from complaining about
it. Even though the RCU protected code of the tracepoint will never be
called, the condition is hidden within the tracepoint, and even though the
condition prevents RCU code from being called, the lockdep checks are
outside the tracepoint (this is to test tracepoints even when they are not
enabled).
Even though tracepoints should be checked to be RCU safe when they are not
enabled, the condition should still be considered when checking RCU.

Revert "IB/core: Add support for extended query device caps"
While commit
7e36ef8205ff ("IB/core: Temporarily disable
ex_query_device uverb") is correct as it makes the extended
QUERY_DEVICE uverb (which came as part of commit
5a77abf9a97a
("IB/core: Add support for extended query device caps") and commit
860f10a799c8 ("IB/core: Add flags for on demand paging support")) not
available to userspace, it doesn't address the initial issue regarding
ib_copy_to_udata() [1][2].
Additionally, further discussions around this new uverb seems to
conclude it would require a different data structure than the one
currently described in <rdma/ib_user_verbs.h> [3].
Both of these issues require a revert of the changes, so this patch
partially reverts commit
8cdd312cfed7 ("IB/mlx5: Implement the ODP
capability query verb") and commit
860f10a799c8 ("IB/core: Add flags

nilfs2: fix deadlock of segment constructor over I_SYNC flag
Nilfs2 eventually hangs in a stress test with fsstress program. This
issue was caused by the following deadlock over I_SYNC flag between
nilfs_segctor_thread() and writeback_sb_inodes():
nilfs_segctor_thread()
nilfs_segctor_thread_construct()
nilfs_segctor_unlock()
nilfs_dispose_list()
iput()
iput_final()
evict()
inode_wait_for_writeback() * wait for I_SYNC flag
writeback_sb_inodes()
* set I_SYNC flag on inode->i_state
__writeback_single_inode()
do_writepages()
nilfs_writepages()
nilfs_construct_dsync_segment()
nilfs_segctor_sync()
* wait for completion of segment constructor
inode_sync_complete()
* clear I_SYNC flag after __writeback_single_inode() completed
writeback_sb_inodes() calls do_writepages() for dirty inodes after
setting I_SYNC flag on inode->i_state. do_writepages() in turn calls
nilfs_writepages(), which can run segment constructor and wait for its
completion. On the other hand, segment constructor calls iput(), which
can call evict() and wait for the I_SYNC flag on
inode_wait_for_writeback().
Since segment constructor doesn't know when I_SYNC will be set, it
cannot know whether iput() will block or not unless inode->i_nlink has a
non-zero count. We can prevent evict() from being called in iput() by
implementing sop->drop_inode(), but it's not preferable to leave inodes
with i_nlink == 0 for long periods because it even defers file
truncation and inode deallocation. So, this instead resolves the
deadlock by calling iput() asynchronously with a workqueue for inodes
with i_nlink == 0.

memcg, shmem: fix shmem migration to use lrucare
It has been reported that 965GM might trigger
VM_BUG_ON_PAGE(!lrucare && PageLRU(oldpage), oldpage)
in mem_cgroup_migrate when shmem wants to replace a swap cache page
because of shmem_should_replace_page (the page is allocated from an
inappropriate zone). shmem_replace_page expects that the oldpage is not
on LRU list and calls mem_cgroup_migrate without lrucare. This is
obviously incorrect because swapcache pages might be on the LRU list
(e.g. swapin readahead page).
Fix this by enabling lrucare for the migration in shmem_replace_page.
Also clarify that lrucare should be used even if one of the pages might
be on LRU list.
The BUG_ON will trigger only when CONFIG_DEBUG_VM is enabled but even
without that the migration code might leave the old page on an
inappropriate memcg' LRU which is not that critical because the page
would get removed with its last reference but it is still confusing.

mm: pagewalk: call pte_hole() for VM_PFNMAP during walk_page_range
walk_page_range() silently skips vma having VM_PFNMAP set, which leads
to undesirable behaviour at client end (who called walk_page_range).
Userspace applications get the wrong data, so the effect is like just
confusing users (if the applications just display the data) or sometimes
killing the processes (if the applications do something with
misunderstanding virtual addresses due to the wrong data.)
For example for pagemap_read, when no callbacks are called against
VM_PFNMAP vma, pagemap_read may prepare pagemap data for next virtual
address range at wrong index.
Eventually userspace may get wrong pagemap data for a task.
Corresponding to a VM_PFNMAP marked vma region, kernel may report
mappings from subsequent vma regions. User space in turn may account
more pages (than really are) to the task.
In my case I was using procmem, procrack (Android utility) which uses
pagemap interface to account RSS pages of a task. Due to this bug it
was giving a wrong picture for vmas (with VM_PFNMAP set).

IRQCHIP: mips-gic: Avoid rerouting timer IRQs for smp-cmp
Commit
e9de688dac65 ("irqchip: mips-gic: Support local interrupts")
changed the GIC irqchip driver so that all local interrupts were routed
to the same CPU pin used for external interrupts. Unfortunately this
causes a regression when smp-cmp is used. The CPUs are started by the
bootloader and put in a timer based waiting poll loop, but when their
timer interrupts are rerouted to a different IRQ pin which is not
unmasked they never wake up.
Since smp-cmp support is deprecated and everybody who was using it
should be switching to smp-cps which brings up the secondary CPUs
without bootloader assistance, I've gone for the simple fix which can be
easily removed once smp-cmp is removed, rather than a fully generic fix.
In __gic_init() the local GIC_VPE_TIMER_MAP register is read to find the
boot-time routing of the local timer interrupt, and a chained handler is
added to that CPU pin as well as the normal one.

drm/cirrus: Limit modes depending on bpp option
The commit [

provides the full list of modes up to 1280x1024 while the 32bpp can

We might be able to filter out the invalid modes in mode_valid

there for now (let me know if there is a better way to retrieve the
bpp for the probed fb).
So, instead, this patch adds the bpp module option to specify the
maximal bpp explicitly and limits the resolutions in get_modes
depending on its value.
The default value is set to 24 so that the existing stuff keeps
working. If you need a new 32bpp feature, specify cirrus.bpp=32

drivers/net: Disable UFO through virtio
Turned off UFO support to virtio-net based devices due to issues
with IPv6 fragment id generation for UFO packets. The issue
was that IPv6 UFO/GSO implementation expects the fragment id
to be supplied in skb_shinfo(). However, for packets generated
by the VMs, the fragment id is not supplied which causes all
IPv6 fragments to have the id of 0.
The problem is that turning off UFO support on tap/macvtap
as well as virtio devices caused issues with migrations.
Migrations would fail when moving a vm from a kernel supporting
expecting UFO to work to the newer kernels that disabled UFO.
This series provides a partial solution to address the migration
issue. The series allows us to track whether skb_shinfo()->ip6_frag_id
has been set by treating value of 0 as unset.
This lets GSO code to generate fragment ids if they are necessary
(ex: packet was generated by VM or packet socket).
Since v3:
- Resolved build issue when IPv6 is a module.
- Removed trailing white space.
Since v2:
- Rebase and rebuild to make sure everything works. No changes
to the patches were done.
Since v1:
- Removed the skb bit and use value of 0 as tracker.
- Used Eric's suggestion to set fragment id as 0x80000000 if id
generation procedure yeilded a 0 result.
- Consolidated ipv6 id genration code.

If the IPv6 fragment id has not been set and we perform
fragmentation due to UFO, select a new fragment id.
We now consider a fragment id of 0 as unset and if id selection
process returns 0 (after all the pertrubations), we set it to
0x80000000, thus giving us ample space not to create collisions
with the next packet we may have to fragment.
When doing UFO integrity checking, we also select the
fragment id if it has not be set yet. This is stored into
the skb_shinfo() thus allowing UFO to function correclty.

sched/deadline: Fix deadline parameter modification handling
Commit
67dfa1b756f2 ("sched/deadline: Implement cancel_dl_timer() to
use in switched_from_dl()") removed the hrtimer_try_cancel() function
call out from init_dl_task_timer(), which gets called from
__setparam_dl().
The result is that we can now re-init the timer while its active --
this is bad and corrupts timer state.
Furthermore; changing the parameters of an active deadline task is
tricky in that you want to maintain guarantees, while immediately
effective change would allow one to circumvent the CBS guarantees --
this too is bad, as one (bad) task should not be able to affect the
others.
Rework things to avoid both problems. We only need to initialize the
timer once, so move that to __sched_fork() for new tasks.
Then make sure __setparam_dl() doesn't affect the current running
state but only updates the parameters used to calculate the next
scheduling period -- this guarantees the CBS functions as expected
(albeit slightly pessimistic).
This however means we need to make sure __dl_clear_params() needs to
reset the active state otherwise new (and tasks flipping between
classes) will not properly (re)compute their first instance.
Todo: close class flipping CBS hole.
Todo: implement delayed BW release.
