4da9484bde x86, hibernate: Initialize mmu_cr4_features during boot
Restore the initialization of mmu_cr4_features during boot, which was
removed without comment in checkin e5f15b45dd

x86: Cleanup highmap after brk is concluded

thereby breaking resume from hibernate.  This restores previous
functionality in approximately the same place, and corrects the
reading of %cr4 on pre-CPUID hardware (%cr4 exists if and only if
CPUID is supported.)

However, part of the problem is that the hibernate suspend/resume
sequence should manage the save/restore of %cr4 explicitly.

47482f132a 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.

Change notes:
v2:
	Filtered UDP to only arm RFS on bound sockets (Eric Dumazet)

34206f2671 can: mcp251x: Allow pass IRQ flags through platform data.
When an interrupt occurs, the INT pin is driven low by the
MCP251x controller (falling edge) but in some cases the INT
pin can be connected to the MPU through a transistor or level
translator which inverts this signal. In this case interrupt
should be configured in rising edge.

This patch adds support to pass the IRQ flags via
mcp251x_platform_data.

bd22f5cfcf KVM: move and fix substitue search for missing CPUID entries
If KVM cannot find an exact match for a requested CPUID leaf, the
code will try to find the closest match instead of simply confessing
it's failure.
The implementation was meant to satisfy the CPUID specification, but
did not properly check for extended and standard leaves and also
didn't account for the index subleaf.
Beside that this rule only applies to CPUID intercepts, which is not
the only user of the kvm_find_cpuid_entry() function.

So fix this algorithm and call it from kvm_emulate_cpuid().
This fixes a crash of newer Linux kernels as KVM guests on
AMD Bulldozer CPUs, where bogus values were returned in response to
a CPUID intercept.

d0de4dc584 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 a2ae4cc9a1
("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
casing of struct user or user->inotify_devs.

a63a5cf84d 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)

b710a48055 block: get rid of elv_insert() interface
Merge it with __elv_add_request(), it's pretty pointless to
have a function with only two callers. The main interface
is elv_add_request()/__elv_add_request().

8182924bc5 block: dump request state on seeing a corrupted request completion
Currently we just dump a non-informative 'request botched' message.
Lets actually try and print something sane to help debug issues
around this.
