snoop_file_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.
Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.

There is no need to split some of the lines. However, improve the style
of multi-line comment. On top of this there is no need to have double
space.
Correct above indentation issues without altering the functionality.

Add kcov_remote_start()/kcov_remote_stop() annotations to the
vhost_worker() function, which is responsible for processing vhost
works.
Since vhost_worker() threads are spawned per vhost device instance the
common kcov handle is used for kcov_remote_start()/stop() annotations
(see Documentation/dev-tools/kcov.rst for details). As the result kcov
can now be used to collect coverage from vhost worker threads.

Add kcov_remote_start()/kcov_remote_stop() annotations to the
hub_event() function, which is responsible for processing events on USB
buses, in particular events that happen during USB device enumeration.
Since hub_event() is run in a global background kernel thread (see
Documentation/dev-tools/kcov.rst for details), each USB bus gets a
unique global handle from the USB subsystem kcov handle range. As the
result kcov can now be used to collect coverage from events that happen
on a particular USB bus.

Statistics in vmstat is combined from counters with different structure,
but names for them are merged into one array.
This patch adds trivial helpers to get name for each item:
const char *zone_stat_name(enum zone_stat_item item);
const char *numa_stat_name(enum numa_stat_item item);
const char *node_stat_name(enum node_stat_item item);
const char *writeback_stat_name(enum writeback_stat_item item);
const char *vm_event_name(enum vm_event_item item);
Names for enum writeback_stat_item are folded in the middle of
vmstat_text so this patch moves declaration into header to calculate
offset of following items.
Also this patch reuses piece of node stat names for lru list names:
const char *lru_list_name(enum lru_list lru);
This returns common lru list names: "inactive_anon", "active_anon",
"inactive_file", "active_file", "unevictable".

This increment of rmi_smbus in rmi_smb_read/write_block() causes
garbage to be read/written.
The first read of SMB_MAX_COUNT bytes is fine, but after that
it is nonsense. Trial-and-error showed that by dropping the
increment of rmiaddr everything is fine and the F54 function
properly works.
I tried a hack with rmi_smb_write_block() as well (writing to the
same F54 touchpad data area, then reading it back), and that
suggests that there too the rmiaddr increment has to be dropped.
It makes sense that if it has to be dropped for read, then it has
to be dropped for write as well.
It looks like the initial work with F54 was done using i2c, not smbus,
and it seems nobody ever tested F54 with smbus. The other functions
all read/write less than SMB_MAX_COUNT as far as I can tell, so this
issue was never noticed with non-F54 functions.
With this change I can read out the touchpad data correctly on my
Lenovo X1 Carbon 6th Gen laptop.

F34 is a bit special as it reinitializes the device and related driver
structs during the firmware update. This clears the fn_irq_mask which
will then prevent F34 from receiving further interrupts, leading to
timeouts during the firmware update. Make sure to reinitialize the
IRQ enables at the appropriate times.
The issue is in F34 code, but the commit in the fixes tag exposed the
issue, as before this commit things would work by accident.

code doesn't delete the payload at current index and just move the
index to next one after shuffling payloads.

Drop the i++ increasing part in for loop head and decide whether
to increase the index or not according to payload_state of current
payload.

ipv6_stub uses the ip6_dst_lookup function to allow other modules to
perform IPv6 lookups. However, this function skips the XFRM layer
entirely.
All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the
ip_route_output_key and ip_route_output helpers) for their IPv4 lookups,
which calls xfrm_lookup_route(). This patch fixes this inconsistent
behavior by switching the stub to ip6_dst_lookup_flow, which also calls
xfrm_lookup_route().
This requires some changes in all the callers, as these two functions
take different arguments and have different return types.

cec4fa7511ef7a73eb635834e9d85b25a5b47a98 ("drm/omap: use refcount API to
track the number of users of dma_addr") changed omap_gem.c to use
refcounting API to track dma_addr uses. However, the driver only tracks
the refcounts for non-contiguous buffers, and the patch didn't fully
take this in account.
After the patch, the driver always decreased refcount in omap_gem_unpin,
instead of decreasing the refcount only for non-contiguous buffers. This
leads to refcounting mismatch.
As for the contiguous cases the refcount is never increased, fix this
issue by returning from omap_gem_unpin if the buffer being unpinned is
contiguous.

So far brd doesn't support un-aligned buffer, even though it is easy
to support it.
However, given brd is often used for debug purpose, and there are other
drivers which can't support un-aligned buffer too.
So add warning so that brd users know what to fix.

Now we depend on blk_queue_split() to respect most of queue limit
(the only one exception could be dma alignment), however
blk_queue_split() isn't used for brd, so this limit isn't respected
since v4.3.
Also max_hw_sectors limit doesn't play a big role for brd, which is
added since brd is added to tree for unknown reason.
So remove it.

The call to tegra_display_hub_cleanup() that takes care of disabling the
window groups is missing from the driver's ->remove() callback. Call it
to make sure the runtime PM reference counts for the display controllers
are balanced.
