Subject: [PATCH] ALSA: hda/realtek - Add quirk for Mac Pro 5,1 machines
A user reported that setting model=imac24 used to allow sound to work on their
Mac Pro 5,1 machine. Commit 5671087ffa "Move ALC885 macpro and imac24 models
to auto-parser" removed this model option. All Mac machines are now explicitly
handled with a quirk and the auto-parser. This adds a quirk for the device
found on the Mac Pro 5,1 machines.
This (partially) fixes https://bugzilla.redhat.com/show_bug.cgi?id=808559

commit 626cf236608505d376e4799adb4f7eb00a8594af
Author: Hans Verkuil <hans.verkuil@cisco.com>
Date: Fri Mar 23 15:02:27 2012 -0700
poll: add poll_requested_events() and poll_does_not_wait() functions
In some cases the poll() implementation in a driver has to do different
things depending on the events the caller wants to poll for. An example
is when a driver needs to start a DMA engine if the caller polls for
POLLIN, but doesn't want to do that if POLLIN is not requested but instead
only POLLOUT or POLLPRI is requested. This is something that can happen
in the video4linux subsystem among others.
Unfortunately, the current epoll/poll/select implementation doesn't
provide that information reliably. The poll_table_struct does have it: it
has a key field with the event mask. But once a poll() call matches one
or more bits of that mask any following poll() calls are passed a NULL
poll_table pointer.
Also, the eventpoll implementation always left the key field at ~0 instead
of using the requested events mask.
This was changed in eventpoll.c so the key field now contains the actual
events that should be polled for as set by the caller.
The solution to the NULL poll_table pointer is to set the qproc field to
NULL in poll_table once poll() matches the events, not the poll_table
pointer itself. That way drivers can obtain the mask through a new
poll_requested_events inline.
The poll_table_struct can still be NULL since some kernel code calls it
internally (netfs_state_poll() in ./drivers/staging/pohmelfs/netfs.h). In
that case poll_requested_events() returns ~0 (i.e. all events).
Very rarely drivers might want to know whether poll_wait will actually
wait. If another earlier file descriptor in the set already matched the
events the caller wanted to wait for, then the kernel will return from the
select() call without waiting. This might be useful information in order
to avoid doing expensive work.
A new helper function poll_does_not_wait() is added that drivers can use
to detect this situation. This is now used in sock_poll_wait() in
include/net/sock.h. This was the only place in the kernel that needed
this information.
Drivers should no longer access any of the poll_table internals, but use
the poll_requested_events() and poll_does_not_wait() access functions
instead. In order to enforce that the poll_table fields are now prepended
with an underscore and a comment was added warning against using them
directly.
This required a change in unix_dgram_poll() in unix/af_unix.c which used
the key field to get the requested events. It's been replaced by a call
to poll_requested_events().
For qproc it was especially important to change its name since the
behavior of that field changes with this patch since this function pointer
can now be NULL when that wasn't possible in the past.
Any driver accessing the qproc or key fields directly will now fail to compile.
Some notes regarding the correctness of this patch: the driver's poll()
function is called with a 'struct poll_table_struct *wait' argument. This
pointer may or may not be NULL, drivers can never rely on it being one or
the other as that depends on whether or not an earlier file descriptor in
the select()'s fdset matched the requested events.
There are only three things a driver can do with the wait argument:
1) obtain the key field:
events = wait ? wait->key : ~0;
This will still work although it should be replaced with the new
poll_requested_events() function (which does exactly the same).
This will now even work better, since wait is no longer set to NULL
unnecessarily.
2) use the qproc callback. This could be deadly since qproc can now be
NULL. Renaming qproc should prevent this from happening. There are no
kernel drivers that actually access this callback directly, BTW.
3) test whether wait == NULL to determine whether poll would return without
waiting. This is no longer sufficient as the correct test is now
wait == NULL || wait->_qproc == NULL.
However, the worst that can happen here is a slight performance hit in
the case where wait != NULL and wait->_qproc == NULL. In that case the
driver will assume that poll_wait() will actually add the fd to the set
of waiting file descriptors. Of course, poll_wait() will not do that
since it tests for wait->_qproc. This will not break anything, though.
There is only one place in the whole kernel where this happens
(sock_poll_wait() in include/net/sock.h) and that code will be replaced
by a call to poll_does_not_wait() in the next patch.
Note that even if wait->_qproc != NULL drivers cannot rely on poll_wait()
actually waiting. The next file descriptor from the set might match the
event mask and thus any possible waits will never happen.

Subject: [PATCH] apple_bl: Add register/unregister functions
Add functions to allow other modules to enable or disable apple_bl. This
will be used by the gmux driver to disable apple_bl when the gmux is
present, as it is a better and more reliable option for brightness
control.

Subject: [PATCH] Bluetooth: Use list _safe deleting from conn chan_list
Fixes possible bug when deleting element from the list in
function hci_chan_list_flush. list_for_each_entry_rcu is used
and after deleting element from the list we also free pointer
and then list_entry_rcu is taken from freed pointer.

Subject: [PATCH] Bluetooth: Use list _safe deleting from conn_hash_list
Use list_for_each_entry_safe which is safe version against removal
of list entry. Otherwise we remove hci_conn element and reference
next element which result in accessing LIST_POISON.

From 268671ffd23264564a62c0893135e2e42e8c4f66 Mon Sep 17 00:00:00 2001
From: Eugeni Dodonov <eugeni.dodonov@intel.com>
Date: Fri, 23 Mar 2012 11:57:18 -0300
Subject: [PATCH] drm/i915: allow to select rc6 modes via kernel parameter
This allows to select which rc6 modes are to be used via kernel parameter,
via a bitmask parameter. E.g.:
- to enable rc6, i915_enable_rc6=1
- to enable rc6 and deep rc6, i915_enable_rc6=3
- to enable rc6 and deepest rc6, use i915_enable_rc6=5
- to enable rc6, deep and deepest rc6, use i915_enable_rc6=7
Please keep in mind that the deepest RC6 state really should NOT be used
by default, as it could potentially worsen the issues with deep RC6. So do
enable it only when you know what you are doing. However, having it around
could help solving possible future rc6-related issues and their debugging
on user machines.
Note that this changes behavior - previously, value of 1 would enable both
RC6 and deep RC6. Now it should only enable RC6 and deep/deepest RC6
stages must be enabled manually.
v2: address Chris Wilson comments and clean up the code.

Subject: [PATCH 2/2] drm/i915: enable plain RC6 on Sandy Bridge by default
This is yet another chapter in the ongoing saga of bringing RC6 to Sandy
Bridge machines by default.
Now that we have discovered that RC6 issues are triggered by RC6+ state,
let's try to disable it by default. Plain RC6 is the one responsible for
most energy savings, and so far it haven't given any problems - at least,
none we are aware of.
So with this, when i915_enable_rc6=-1 (e.g., the default value), we'll
attempt to enable plain RC6 only on SNB. For Ivy Bridge, the behavior
stays the same as always - we enable both RC6 and deep RC6.
Note that while this exact patch does not has explicit tested-by's, the
equivalent settings were fixed in 3.3 kernel by a smaller patch. And it
has also received considerable testing through Canonical RC6 task-force
testing at https://wiki.ubuntu.com/Kernel/PowerManagementRC6. Up to date,
it looks like all the known issues are gone.
v2: improve description and reference a couple of open bugs related to
RC6 which seem to be fixed with this change.

Subject: [PATCH] ext4: Support "check=none" "nocheck" mount options
The ext2/ext3 filesystems supported "check=none" and "nocheck" as mount options
even though that was already the default behavior and it essentially did
nothing. When using ext4 to mount ext2/ext3 filesystems, that mount option
causes the mount to fail. That isn't as backward compatible as it could be,
so add support to ext4 to accept the option.

Subject: [PATCH] ext4: fix resize when resizing within single group
When resizing file system in the way that the new size of the file
system is still in the same group (no new groups are added), then we can
hit a BUG_ON in ext4_alloc_group_tables()
BUG_ON(flex_gd->count == 0 || group_data == NULL);
because flex_gd->count is zero. The reason is the missing check for such
case, so the code always extend the last group fully and then attempt to
add more groups, but at that time n_blocks_count is actually smaller
than o_blocks_count.
It can be easily reproduced like this:
mkfs.ext4 -b 4096 /dev/sda 30M
mount /dev/sda /mnt/test
resize2fs /dev/sda 50M
Fix this by checking whether the resize happens within the singe group
and only add that many blocks into the last group to satisfy user
request. Then o_blocks_count == n_blocks_count and the resize will exit
successfully without and attempt to add more groups into the fs.
Also fix mixing together block number and blocks count which might be
confusing and can easily lead to off-by-one errors (but it is actually
not the case here since the two occurrence of this mix-up will cancel
each other).

Subject: [PATCH v5 0/3] virtio-scsi driver
This is the first implementation of the virtio-scsi driver, a virtual
HBA that will be supported by KVM. It implements a subset of the spec,
in particular it does not implement asynchronous notifications for either
LUN reset/removal/addition or CD-ROM media events, but it is already
functional and usable.
Other matching bits:
- spec at http://people.redhat.com/pbonzini/virtio-spec.pdf
- QEMU implementation at git://github.com/bonzini/qemu.git,
branch virtio-scsi
Please review. Getting this in 3.3 is starting to look like wishful thinking,
but the possibility of regressions is obviously zero so I'm still dreaming.
Otherwise, that would be 3.4.
Paolo Bonzini (3):
virtio-scsi: first version
virtio-scsi: add error handling
virtio-scsi: add power management support
v4->v5: change virtio id from 7 to 8
v3->v4: renamed VIRTIO_SCSI_S_UNDERRUN to VIRTIO_SCSI_S_OVERRUN;
fixed 32-bit compilation; added power management support;
adjusted calls to virtqueue_add_buf

The virtio-scsi HBA is the basis of an alternative storage stack
for QEMU-based virtual machines (including KVM). Compared to
virtio-blk it is more scalable, because it supports many LUNs
on a single PCI slot), more powerful (it more easily supports
passthrough of host devices to the guest) and more easily
extensible (new SCSI features implemented by QEMU should not
require updating the driver in the guest).

v4->v5: change virtio id from 7 to 8
v3->v4: renamed VIRTIO_SCSI_S_UNDERRUN to VIRTIO_SCSI_S_OVERRUN;
fixed 32-bit compilation; adjust call to virtqueue_add_buf
v2->v3: added mempool, formatting fixes
v1->v2: use dbg_dev, sdev_printk, scmd_printk
- renamed lock to vq_lock
- renamed cmd_vq to req_vq (and other similar changes)
- fixed missing break in VIRTIO_SCSI_S_OVERRUN
- added VIRTIO_SCSI_S_BUSY
- removed unused argument from virtscsi_map_cmd
- fixed two tabs that had slipped in
- moved max_sectors and cmd_per_lun from template to config space
- __attribute__((packed)) -> __packed

From 574e02abaf816b582685805f0c1150ca9f1f18ee Mon Sep 17 00:00:00 2001
From: Larry Finger <Larry.Finger@lwfinger.net>
Date: Fri, 4 May 2012 08:27:43 -0500
Subject: [PATCH] rtlwifi: fix for race condition when firmware is cached
In commit b0302ab, the rtlwifi family of drivers was converted to use
asynchronous firmware loading. Unfortumately, the implementation was
racy, and the ieee80211 routines could be started before rtl_init_core()
was called to setup the data.
This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187.

From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
Xen dom0 needs to paravirtualize IO operations to the IO APIC, so add
a io_apic_ops for it to intercept. Do this as ops structure because
there's at least some chance that another paravirtualized environment
may want to intercept these.
