Commit f44f7f96a2 ("RTC: Initialize kernel state from RTC") caused a
boot regression on the MRST platform.
The reason is that rtc_device_register() calls rtc_read_alarm() after
that change, which function does not have all driver data set up yet.
The rtc-mrst driver needs to call dev_set_drvdata() before rtc_device_register()
gets called.

For isochronous packets the actual_length is the sum of the actual
length of each of the packets, however between the packets might be
padding, so it is not sufficient to just send the first actual_length
bytes of the buffer. To fix this and simultanesouly optimize the
bandwidth the content of the isochronous packets are send without the
padding, the padding is restored on the receiving end.

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.

Xen fails to mask XSAVE from the cpuid feature, despite not historically
supporting guest use of XSAVE. However, now that XSAVE support has been
added to Xen, we need to reliably detect its presence.
The most reliable way to do this is to look at the OSXSAVE feature in
cpuid which is set iff the OS (Xen, in this case), has set
CR4.OSXSAVE.

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

When KVM scans the 0xD CPUID leaf for propagating the XSAVE save area
leaves, it assumes that the leaves are contigious and stops at the
first zero one. On AMD hardware there is a gap, though, as LWP uses
leaf 62 to announce it's state save area.
So lets iterate through all 64 possible leaves and simply skip zero
ones to also cover later features.

move the initializtion of s_err_report earlier so that we can avoid
