perf probe: Fix listing incorrect line number with inline function
Fix a bug showing incorrect line number when a probe is put on the head of an
inline function. This patch updates find_perf_probe_point() and introduces new
rules to get correct line number.
- If debuginfo doesn't have a correct file name, we shouldn't return line
number too, because, without file name, line number is meaningless.
- If the address is in a function, it stores the function name and the offset
from the function entry.
- If the address is on a line, it tries to get the relative line number from
the function entry line, except for the address is same as the entry
address of the function (in this case, the relative line number should
be 0).
- If the address is in an inline function entry (call-site), it uses the
inline function call line number as the line on which the address is.
- If the address is in an inline function body, it stores the inline
function name and offset from the inline function call site instead of the
(non-inlined) function.

This is a moral revert of
6ec3d0c0e9c0c605696e91048eebaca7b0c36695.
Following the fix to reset the GMBUS controller after a NAK, we finally
utilize the 0xa0 probe for a CRT connection. And discover that the code
is broken. Shock.
There are a number of issues, but following a key insight from Dave
Airlie, that 0xA0 is an invalid address on a 7-bit bus (though not if we
were to enable 10-bit addressing), and would look like the EDID port
0x50, it is possible to see where the confusion starts.
In short, a write to 0xA0 is accepted by the GMBUS controller which we
interpreted as meaning the existence of a connection (a slave on the
other end of the wire ACKing the write). That was false.
During testing with a broken GMBUS implementation, which never reset an
earlier NAK, this test always reported a NAK and so we proceeded on to
the next test.

Btrfs: don't warn in btrfs_add_orphan
When I moved the orphan adding to btrfs_truncate I missed the fact that during
orphan cleanup we just add the orphan items to the orphan list without going
through btrfs_orphan_add, which results in lots of warnings on mount if you have
any orphan items that need to be truncated. Just remove this warning since it's
ok, this will allow all of the normal space accounting take place. Thanks,

Btrfs: fix free space cache when there are pinned extents and clusters V2
I noticed a huge problem with the free space cache that was presenting
as an early ENOSPC. Turns out when writing the free space cache out I
forgot to take into account pinned extents and more importantly
clusters. This would result in us leaking free space everytime we
unmounted the filesystem and remounted it.
I fix this by making sure to check and see if the current block group
has a cluster and writing out any entries that are in the cluster to the
cache, as well as writing any pinned extents we currently have to the
cache since those will be available for us to use the next time the fs
mounts.
This patch also adds a check to the end of load_free_space_cache to make
sure we got the right amount of free space cache, and if not make sure
to clear the cache and re-cache the old fashioned way.

Btrfs: Fix uninitialized root flags for subvolumes
root_item->flags and root_item->byte_limit are not initialized when
a subvolume is created. This bug is not revealed until we added
readonly snapshot support - now you mount a btrfs filesystem and you
may find the subvolumes in it are readonly.
To work around this problem, we steal a bit from root_item->inode_item->flags,
and use it to indicate if those fields have been properly initialized.
When we read a tree root from disk, we check if the bit is set, and if
not we'll set the flag and initialize the two fields of the root item.

tty: fix endless work loop when the buffer fills up
Commit
f23eb2b2b285 ('tty: stop using "delayed_work" in the tty layer')
ended up causing hung machines on UP with no preemption, because the
work routine to flip the buffer data to the ldisc would endlessly re-arm
itself if the destination buffer had filled up.
With the delayed work, that only caused a timer-driving polling of the
tty state every timer tick, but without the delay we just ended up with
basically a busy loop instead.
Stop the insane polling, and instead make the code that opens up the
receive room re-schedule the buffer flip work. That's what we should
have been doing anyway.
This same "poll for tty room" issue is almost certainly also the cause
of excessive kworker activity when idle reported by Dave Jones, who also
reported "flush_to_ldisc executing 2500 times a second" back in Nov 2010:
http://lkml.org/lkml/2010/11/30/592

mac80211: fix comment regarding aggregation buf_size
The description for buf_size was misleading and
just said you couldn't TX larger aggregates, but
of course you can't TX aggregates in a way that
would exceed the window either, which is possible
even if the aggregates are shorter than that.
Expand the description, thanks to Emmanuel for
explaining this to me.

ntp: fix non privileged system time shifting

094aa188 ("ntp: Add ADJ_SETOFFSET

Sneaky or buggy calls to adjtimex() could set
ADJ_OFFSET_SS_READ | ADJ_SETOFFSET

to an interface, but this flag cannot be set via struct flowi.
Also, it cannot be set via ip6_route_output: this function uses the

Work around this by passing in an artificial struct sk in case
