+Subject: ALSA: cmipci: work around invalid PCM pointer
+
+From: Clemens Ladisch <clemens@ladisch.de>
+
+commit 1c583063a5c769fe2ec604752e383972c69e6d9b upstream.
+
+When the CMI8738 FRAME2 register is read, the chip sometimes (probably
+when wrapping around) returns an invalid value that would be outside the
+programmed DMA buffer. This leads to an inconsistent PCM pointer that is
+likely to result in an underrun.
+
+To work around this, read the register multiple times until we get a
+valid value; the error state seems to be very short-lived.

+commit 80c43ed724797627d8f86855248c497a6161a214 upstream.
+
+Judging from the member of enable_msi white-list, Nvidia controller
+seems to cause troubles with MSI enabled, e.g. boot hang up or other
+serious issue may come up. It's safer to disable MSI as default for

+The OR has verified that his hardware distorts because of the 0 dB

+From: John Kacur <jkacur@redhat.com>
+
+commit 7ae5f21361fea11f58c398701da635f778635d13 upstream.
+
+Without this change, the install path is relative to
+prefix/DESTDIR where prefix is automatically set to $HOME.
+
+This can produce unexpected results. For example:
+
+ make -C tools/perf DESTDIR=/home/jkacur/tmp install-man
+
+creates the directory: /home/jkacur/home/jkacur/tmp/share/...
+instead of the expected: /home/jkacur/tmp/share/...

+Subject: perf_event: Fix oops triggered by cpu offline/online
+
+From: Paul Mackerras <paulus@samba.org>
+
+commit 220b140b52ab6cc133f674a7ffec8fa792054f25 upstream.
+
+Anton Blanchard found that he could reliably make the kernel hit a
+BUG_ON in the slab allocator by taking a cpu offline and then online
+while a system-wide perf record session was running.
+
+The reason is that when the cpu comes up, we completely reinitialize
+the ctx field of the struct perf_cpu_context for the cpu. If there is
+a system-wide perf record session running, then there will be a struct
+perf_event that has a reference to the context, so its refcount will
+be 2. (The perf_event has been removed from the context's group_entry
+and event_entry lists by perf_event_exit_cpu(), but that doesn't
+remove the perf_event's reference to the context and doesn't decrement
+the context's refcount.)
+
+When the cpu comes up, perf_event_init_cpu() gets called, and it calls
+__perf_event_init_context() on the cpu's context. That resets the
+refcount to 1. Then when the perf record session finishes and the
+perf_event is closed, the refcount gets decremented to 0 and the
+context gets kfreed after an RCU grace period. Since the context
+wasn't kmalloced -- it's part of a per-cpu variable -- bad things
+happen.
+
+In fact we don't need to completely reinitialize the context when the
+cpu comes up. It's sufficient to initialize the context once at boot,
+but we need to do it for all possible cpus.
+
+This moves the context initialization to happen at boot time. With
+this, we don't trash the refcount and the context never gets kfreed,
+and we don't hit the BUG_ON.

+Subject: SCSI: scsi_transport_fc: Fix synchronization issue while deleting vport
+
+From: Gal Rosen <galr@storwize.com>
+
+commit 0d9dc7c8b9b7fa0f53647423b41056ee1beed735 upstream.
+
+The issue occur while deleting 60 virtual ports through the sys
+interface /sys/class/fc_vports/vport-X/vport_delete. It happen while in
+a mistake each request sent twice for the same vport. This interface is
+asynchronous, entering the delete request into a work queue, allowing
+more than one request to enter to the delete work queue. The result is a
+NULL pointer. The first request already delete the vport, while the
+second request got a pointer to the vport before the device destroyed.
+Re-create vport later cause system freeze.
+
+Solution: Check vport flags before entering the request to the work queue.

+
+From: Ravikiran G Thirumalai <kiran@scalex86.org>
+
+commit 413b43deab8377819aba1dbad2abf0c15d59b491 upstream.
+
+Fix an 'oops' when a tmpfs mount point is mounted with the mpol=default
+mempolicy.
+
+Upon remounting a tmpfs mount point with 'mpol=default' option, the mount
+code crashed with a null pointer dereference. The initial problem report
+was on 2.6.27, but the problem exists in mainline 2.6.34-rc as well. On
+examining the code, we see that mpol_new returns NULL if default mempolicy
+was requested. This 'NULL' mempolicy is accessed to store the node mask
+resulting in oops.
+
+The following patch fixes it.

+Subject: tmpfs: handle MPOL_LOCAL mount option properly
+
+From: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>
+
+commit 12821f5fb942e795f8009ece14bde868893bd811 upstream.
+
+commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in
+shmem_sb_info) added mpol=local mount option. but its feature is broken
+since it was born. because such code always return 1 (i.e. mount
+failure).
+
+This patch fixes it.

+Subject: tmpfs: mpol=bind:0 don't cause mount error.
+
+From: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>
+
+commit d69b2e63e9172afb4d07c305601b79a55509ac4c upstream.
+
+Currently, following mount operation cause mount error.
+
+% mount -t tmpfs -ompol=bind:0 none /tmp
+
+Because commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in
+shmem_sb_info) corrupted MPOL_BIND parse code.
+
+This patch restore the needed one.
