The as3722 device is registered as an irqchip and the as3722-rtc interrupt
is one of it's interrupt sources. When using the as3722-rtc as a wake-up
device from suspend, the following is seen:
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.001 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
Suspending console(s) (use no_console_suspend to debug)

as3722 4-0040: Failed to read IRQ status: -16
as3722 4-0040: Failed to read IRQ status: -16
...
The reason why the as3722 interrupt status cannot be read is because the
as3722 interrupt is not masked during suspend and when the as3722-rtc
interrupt occurs, to wake-up the device, the interrupt is seen before the
i2c controller has been resumed in order to read the as3722 interrupt
status.
The as3722-rtc driver sets it's interrupt as a wake-up source during
suspend, which gets propagated to the parent as3722 interrupt. However,
the as3722-rtc driver cannot disable it's interrupt during suspend
otherwise we would never be woken up and so the as3722 must disable it's
interrupt instead.
Fix this by disabling the as3722 interrupt during suspend. To ensure that
a wake-up event from the as3722 is not missing, enable the as3722 interrupt
as a wake-up source before disabling the interrupt on entering suspend.

The problem is in pmd_pfn_mask() and pmd_flags_mask(). These
helpers use PMD_PAGE_MASK to calculate resulting mask.
PMD_PAGE_MASK is 'unsigned long', not 'unsigned long long' as
phys_addr_t is on 32-bit PAE (ARCH_PHYS_ADDR_T_64BIT). As a
result, the upper bits of resulting mask get truncated.
pud_pfn_mask() and pud_flags_mask() aren't problematic since we
don't have PUD page table level on 32-bit systems, but it's
reasonable to keep them consistent with PMD counterpart.
Introduce PHYSICAL_PMD_PAGE_MASK and PHYSICAL_PUD_PAGE_MASK in
addition to existing PHYSICAL_PAGE_MASK and reworks helpers to
use them.

'range_new' doesn't seem to be used after init. It is only passed
to memset(), sum_ranges(), memcmp() and x86_get_mtrr_mem_range(), the
latter of which also only passes it on to various *range*
library functions.
So mark it __initdata to free up an extra page after init.
Its contents are wiped at every call to mtrr_calc_range_state(),
so it being static is not about preserving state between calls,
but simply to avoid a 4k+ stack frame. While there, add a
comment explaining this and why it's safe.
We could also mark nr_range_new as __initdata, but since it's
just a single int and also doesn't carry state between calls (it
is unconditionally assigned to before it is read), we might as
well make it an ordinary automatic variable.

Before the system go to suspend (S3), if user create a timer
with clockid CLOCK_REALTIME_ALARM/CLOCK_BOOTTIME_ALARM and set a
"large" timeout value to this timer. The function
alarmtimer_suspend will be called to setup a timeout value to
RTC timer to avoid the system sleep over time. However, if the
system wakeup early than RTC timeout, the RTC timer will not be
cleared. And this will cause the hpet_rtc_interrupt come
unexpectedly until the RTC timeout. To fix this problem, just
adding alarmtimer_resume to cancel the RTC timer.
This was noticed because the HPET RTC emulation fires an
interrupt every 16ms(=1/2^DEFAULT_RTC_SHIFT) up to the point
where the alarm time is reached.
This program always hits this situation
(https://lkml.org/lkml/2015/11/8/326), if system wake up earlier
than alarm time.

drm/irq: Make pipe unsigned and name consistent
Triggering a warning when trying to sample the vblank timestamp for a
non-existing pipe. There's a few ways to fix this:
- Open-code the old behaviour, which just enshrines this slight
breakage of the userspace ABI.
- Revert Mario's commit and again inflict broken timestamps, again not
pretty.
- Fix this for real by delaying the pageflip TS until the next vblank
interrupt, thereby making it accurate.
This patch implements the third option. Since having a page flip
interrupt that happens when the pageflip gets armed and not when it
completes in the next vblank seems to be fairly common (older i915 hw
works very similarly) create a new helper to arm vblank events for
such drivers.
v2 (Mario Kleiner):
- Fix function prototypes in drmP.h
- Add missing vblank_put() for pageflip completion without
pageflip event.
- Initialize sequence number for queued pageflip event to avoid
trouble in drm_handle_vblank_events().
- Remove dead code and spelling fix.
v3 (Mario Kleiner):
- Add a signed-off-by and cc stable tag per Ilja's advice.
v4 (Thierry Reding):
- Fix kerneldoc typo, discovered by Michel Dänzer
- Rearrange tags and changelog

The routines in scsi_pm.c assume that if a runtime-PM callback is
invoked for a SCSI device, it can only mean that the device's driver
has asked the block layer to handle the runtime power management (by
calling blk_pm_runtime_init(), which among other things sets q->dev).
However, this assumption turns out to be wrong for things like the ses
driver. Normally ses devices are not allowed to do runtime PM, but
userspace can override this setting. If this happens, the kernel gets
a NULL pointer dereference when blk_post_runtime_resume() tries to use
the uninitialized q->dev pointer.
This patch fixes the problem by checking q->dev in block layer before
handle runtime PM. Since ses doesn't define any PM callbacks and call
blk_pm_runtime_init(), the crash won't occur.
This fixes Bugzilla #101371.

These devices have a pen device and a touch device through the same serial
protocol, split it up into two separate devices like we do for USB Wacom
tablets too.
Userspace already matches on the device name so we can't drop it
completely. Compose the same basename based on capabilities and append the
tool type, leading to a name like "Wacom Serial Penabled 2FG Touchscreen
Pen".
Note that this drops BTN_TOOL_FINGER, it is not needed once the tools
are split out (and a touch device with BTN_TOOL_FINGER is interpreted
as touchpad by most of userspace).

nothing but a name and the EV_KEY and EV_ABS bits.

Pull block fixes from Jens Axboe:
"A collection of fixes from this series. The most important here is a
regression fix for an issue that some folks would hit in blk-merge.c,
and the NVMe queue depth limit for the screwed up Apple "nvme"
controller.
In more detail, this pull request contains:
- a set of fixes for null_blk, including a fix for a few corner cases
where we could hang the device. From Arianna and Paolo.
- lightnvm:
- A build improvement from Keith.
- Update the qemu pci id detection from Matias.
- Error handling fixes for leaks and other little fixes from
Sudip and Wenwei.
- fix from Eric where BLKRRPART would not return EBUSY for whole
device mounts, only when partitions were mounted.
- fix from Jan Kara, where EOF O_DIRECT reads would return
negatively.
- remove check for rq_mergeable() when checking limits for cloned
requests. The check doesn't make any sense. It's assuming that
since NOMERGE is set on the request that we don't have to
recalculate limits since the request didn't change, but that's not
true if the request has been redirected. From Hannes.
- correctly get the bio front segment value set for single segment
bio's, fixing a BUG() in blk-merge. From Ming"

Return EBUSY from BLKRRPART for mounted whole-dev fs
events on pids. It filters all events where only tasks with their pid in that
file exists. It also handles the sched_switch and sched_wakeup trace events
where the current task does not have its pid in the file, but the task
either being switched to or awaken does.
Unfortunately, I forgot about sched_wakeup_new and sched_waking. Both of
these tracepoints use the same class as the sched_wakeup tracepoint, and
they too should be included in what gets filtered by the set_event_pid file.

The following directory structure will allow for cases when the same
function name exists in a single object.
/sys/kernel/livepatch/<patch>/<object>/<function,sympos>
The sympos number corresponds to the nth occurrence of the symbol name in
kallsyms for the patched object.
An example of patching multiple symbols can be found here:

In cases of duplicate symbols, sympos will be used to disambiguate instead
of val. By default sympos will be 0, and patching will only succeed if
the symbol is unique. Specifying a positive value will ensure that
occurrence of the symbol in kallsyms for the patched object will be used
for patching if it is valid. For external relocations sympos is not
supported.
Remove klp_verify_callback, klp_verify_args and klp_verify_vmlinux_symbol
as they are no longer used.
From the klp_reloc structure remove val, as it can be refactored as a
local variable in klp_write_object_relocations.

Currently, patching objects with duplicate symbol names fail because the
creation of the sysfs function directory collides with the previous
attempt. Appending old_addr to the function name is problematic as it
reveals the address of the function being patch to a normal user. Using
the symbol's occurrence in kallsyms to postfix the function name in the
sysfs directory solves the issue of having consistent unique names and
ensuring that the address is not exposed to a normal user.
In addition, using the symbol position as the user's method to disambiguate
symbols instead of addr allows for disambiguating symbols in modules as
well for both function addresses and for relocs. This also simplifies much
of the code. Special handling for kASLR is no longer needed and can be
removed. The klp_find_verify_func_addr function can be replaced by
klp_find_object_symbol, and klp_verify_vmlinux_symbol and its callback can
be removed completely.
In cases of duplicate symbols, old_sympos will be used to disambiguate
instead of old_addr. By default old_sympos will be 0, and patching will
only succeed if the symbol is unique. Specifying a positive value will
ensure that occurrence of the symbol in kallsyms for the patched object
will be used for patching if it is valid.
In addition, make old_addr an internal structure field not to be specified
by the user. Finally, remove klp_find_verify_func_addr as it can be
replaced by klp_find_object_symbol directly.
Support for symbol position disambiguation for relocations is added in the
next patch in this series.

If the driver were to happen to have a mutex held while
the i40e_init_adminq call was called, the init_adminq might
inadvertently call mutex_init on a lock that was held
which is a violation of the calling semantics.
Fix this by avoiding adminq.c code allocating/freeing this memory, and
then do the same work only once in probe/remove.
Testing Hints (Required if no HSD): for VF, load i40evf in bare metal
and echo 32 > sriov_numvfs; echo 0 > sriov_numvfs in a loop. Yes this
is a horrible thing to do.

Enabling SR-IOV and then bringing the interface up was resulting in the PF
MAC addresses getting into a bad state. Specifically the MAC address was
enabled for both VF 0 and the PF. This resulted in some odd behaviors such
as VF 0 receiving a copy of the PFs traffic, which in turn enables the
ability for VF 0 to spoof the PF.
A workaround for this issue appears to be to bring up the interface first
and then enable SR-IOV as this way the reset is then triggered in the
existing code.
In order to correct this I have added a change to ixgbe_setup_tc where if
the interface is down we still will at least call ixgbe_reset so that the
MAC addresses for the device are reset to the correct pools.
Steps to reproduce issue:
modprobe ixgbe
echo 7 > /sys/bus/pci/devices/0000\:01\:00.1/sriov_numvfs
ifconfig enp1s0f1 up
ethregs -s 1:00.1 | grep MPSAR | grep -v 00000000
Result:
MPSAR[0] 00000081
MPSAR[254] 00000001
Expected Result, behavior after patch:
MPSAR[0] 00000080
MPSAR[254] 00000080

Commit 5405ff6e15 ("tipc: convert node lock to rwlock")
introduced a bug to the node reference counter handling. When a
message is successfully sent in the function tipc_node_xmit(),
we return directly after releasing the node lock, instead of
continuing and decrementing the node reference counter as we
should do.
