Linus Torvalds 982134ba62 mm: avoid wrapping vm_pgoff in mremap()
The normal mmap paths all avoid creating a mapping where the pgoff
inside the mapping could wrap around due to overflow.  However, an
expanding mremap() can take such a non-wrapping mapping and make it
bigger and cause a wrapping condition.

Noticed by Robert Swiecki when running a system call fuzzer, where it
caused a BUG_ON() due to terminally confusing the vma_prio_tree code.  A
vma dumping patch by Hugh then pinpointed the crazy wrapped case.

Aaron Plattner 1f34852284 ALSA: hda - HDMI: Fix MCP7x audio infoframe checksums
The MCP7x hardware computes the audio infoframe channel count
automatically, but requires the audio driver to set the audio
infoframe checksum manually via the Nv_VERB_SET_Info_Frame_Checksum
control verb.

When audio starts playing, nvhdmi_8ch_7x_pcm_prepare sets the checksum
to (0x71 - chan - chanmask).  For example, for 2ch audio, chan == 1
and chanmask == 0 so the checksum is set to 0x70.  When audio playback
finishes and the device is closed, nvhdmi_8ch_7x_pcm_close resets the
channel formats, causing the channel count to revert to 8ch.  Since
the checksum is not reset, the hardware starts generating audio
infoframes with invalid checksums.  This causes some displays to blank
the video.

Fix this by updating the checksum and channel mask when the device is
closed and also when it is first initialized.  In addition, make sure
that the channel mask is appropriate for an 8ch infoframe by setting
it to 0x13 (FL FR LFE FC RL RR RLC RRC).

Feng Tang de97a21a23 rtc, x86/mrst/vrtc: Fix boot crash in rtc_read_alarm()
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.

However, part of the problem is that the hibernate suspend/resume

Neil Horman 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.

Trond Myklebust 0867659fa3 Revert "net/sunrpc: Use static const char arrays"
This reverts commit 411b5e0561.

Olga Kornievskaia reports:

Problem: linux client mounting linux server using rc4-hmac-md5
enctype. gssd fails with create a context after receiving a reply from
the server.

Diagnose: putting printout statements in the server kernel and
kerberos libraries revealed that client and server derived different
integrity keys.

Server kernel code was at fault due the the commit

[aglo@skydive linux-pnfs]$ git show 411b5e0561

Trond: The problem is that since it relies on virt_to_page(), you cannot
call sg_set_buf() for data in the const section.

Andre Przywara 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.

Andre Przywara 20800bc940 KVM: fix XSAVE bit scanning
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.

Tao Ma 0449641130 ext4: init timer earlier to avoid a kernel panic in __save_error_info
During mount, when we fail to open journal inode or root inode, the
__save_error_info will mod_timer. But actually s_err_report isn't
initialized yet and the kernel oops. The detailed information can
be found https://bugzilla.kernel.org/show_bug.cgi?id=32082.

The best way is to check whether the timer s_err_report is initialized
or not. But it seems that in include/linux/timer.h, we can't find a
good function to check the status of this timer, so this patch just
move the initializtion of s_err_report earlier so that we can avoid
the kernel panic. The corresponding del_timer is also added in the
error path.
