ipv6: Enable RFS sk_rxhash tracking for ipv6 sockets (v2)
properly record sk_rxhash in ipv6 sockets (v2)
Noticed while working on another project that flows to sockets which I had open
on a test systems weren't getting steered properly when I had RFS enabled.
Looking more closely I found that:
1) The affected sockets were all ipv6
2) They weren't getting steered because sk->sk_rxhash was never set from the
incomming skbs on that socket.
This was occuring because there are several points in the IPv4 tcp and udp code
which save the rxhash value when a new connection is established. Those calls
to sock_rps_save_rxhash were never added to the corresponding ipv6 code paths.
This patch adds those calls. Tested by myself to properly enable RFS
functionalty on ipv6.

KVM: move and fix substitue search for missing CPUID entries

Beside that this rule only applies to CPUID intercepts, which is not

inotify: fix double free/corruption of stuct user
On an error path in inotify_init1 a normal user can trigger a double
free of struct user. This is a regression introduced by
a2ae4cc9a16e
("inotify: stop kernel memory leak on file creation failure").
We fix this by making sure that if a group exists the user reference is
dropped when the group is cleaned up. We should not explictly drop the
reference on error and also drop the reference when the group is cleaned
up.
The new lifetime rules are that an inotify group lives from
inotify_new_group to the last fsnotify_put_group. Since the struct user
and inotify_devs are directly tied to this lifetime they are only
changed/updated in those two locations. We get rid of all special

dm: improve block integrity support
The current block integrity (DIF/DIX) support in DM is verifying that
all devices' integrity profiles match during DM device resume (which
is past the point of no return). To some degree that is unavoidable
(stacked DM devices force this late checking). But for most DM
devices (which aren't stacking on other DM devices) the ideal time to
verify all integrity profiles match is during table load.
Introduce the notion of an "initialized" integrity profile: a profile
that was blk_integrity_register()'d with a non-NULL 'blk_integrity'
template. Add blk_integrity_is_initialized() to allow checking if a
profile was initialized.
Update DM integrity support to:
- check all devices with _initialized_ integrity profiles match
during table load; uninitialized profiles (e.g. for underlying DM
device(s) of a stacked DM device) are ignored.
- disallow a table load that would result in an integrity profile that
conflicts with a DM device's existing (in-use) integrity profile
- avoid clearing an existing integrity profile
- validate all integrity profiles match during resume; but if they
don't all we can do is report the mismatch (during resume we're past
the point of no return)

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

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.

drm/i915/lvds: Remove 0xa0 DDC probe for LVDS
This is a revert of
428d2e828c0a68206e5158a42451487601dc9194.
This is broken in the same manner as for VGA: trying to write to an
invalid address on the (currently 7-bit) i2c bus.
One notable failure appears to be for MacBooks. The scary part was that
it gave the appearance of working (i.e. reporting the absence of the
panel) on various all-in-one machines with ghost LVDS panels and not
failing for laptops.

drm/i915/crt: Remove 0xa0 probe for VGA
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.
