This is sync with Linus' tree to receive KEY_IMAGES definition
that went in through input tree.

startup_profile and actual_profile didn't work as expected. Also
as the actual profile is persistent, the distinction between the
two was ambiguous, so both use the same code now and startup_profile
has been deprecated. Also the event is now propagated through
chardev. The userland tool has been updated to support this change.

During pci remove/rescan testing found:

pcieport: probe of 0000:c0:03.0 failed with error -22
This bug was caused by commit c8adf9a3e873 ("PCI: pre-allocate
additional resources to devices only after successful allocation of
essential resources.")
After that commit, pci_hotplug_io_size is changed to additional_io_size
from minium size. So it will not go through resource_size(res) != 0
path, and will not be reset.
The root cause is: pci_bridge_check_ranges will set RESOURCE_IO flag for
pci bridge, and later if children do not need IO resource. those bridge
resources will not need to be allocated. but flags is still there.
that will confuse the the pci_enable_bridges later.
related code:
static void assign_requested_resources_sorted(struct resource_list *head,
struct resource_list_x *fail_head)
{
struct resource *res;
struct resource_list *list;
int idx;
for (list = head->next; list; list = list->next) {
res = list->res;
idx = res - &list->dev->resource[0];
if (resource_size(res) && pci_assign_resource(list->dev, idx)) {
...
reset_resource(res);
}
}
}
At last, We have to clear the flags in pbus_size_mem/io when requested
size == 0 and !add_head. becasue this case it will not go through
adjust_resources_sorted().
Just make size1 = size0 when !add_head. it will make flags get cleared.
At the same time when requested size == 0, add_size != 0, will still
have in head and add_list. because we do not clear the flags for it.
After this, we will get right result:

Those reduced to DEBUG can possibly be triggered by unprivileged processes
and are nothing exceptional. Illegal checksum combinations can only be
caused by driver bug, so promote those messages to WARN.
Since GSO without SG will now only cause DEBUG message from
netdev_fix_features(), remove the workaround from register_netdevice().

During initialization of vmxnet3, the state of LRO
gets out of sync with netdev->features.
This leads to very poor TCP performance in a IP forwarding
setup and is hitting many VMware users.
Simplified call sequence:
1. vmxnet3_declare_features() initializes "adapter->lro" to true.
2. The kernel automatically disables LRO if IP forwarding is enabled,
so vmxnet3_set_flags() gets called. This also updates netdev->features.
3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still
set to true and LRO gets enabled again, even though
netdev->features shows it's disabled.
Fix it by updating "adapter->lro", too.
The private vmxnet3 adapter flags are scheduled for removal
in net-next, see commit a0d2730c9571aeba793cb5d3009094ee1d8fda35
"net: vmxnet3: convert to hw_features".
Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6.

Commit 747df2258b1b9a2e25929ef496262c339c380009 ('sfc: Always map MCDI
shared memory as uncacheable') introduced a separate mapping for the
MCDI shared memory (MC_TREG_SMEM). This means we can no longer easily
include it in the register dump. Since it is not particularly useful
in debugging, substitute a recognisable dummy value.

We need to hold the dev->mode_config.mutex whilst detecting the output
status. But we also need to drop it for the call into
drm_fb_helper_single_fb_probe(), which indirectly acquires the lock when
attaching the fbcon.
Failure to do so exposes a race with normal output probing. Detected by
adding some warnings that the mutex is held to the backend detect routines:

My Q67 / i7-2600 box has rev09 Sandy Bridge graphics. It hangs
instantly when GNOME loads and it hangs so hard the reset button
doesn't work. Setting i915.semaphore=0 fixes it.

If the requested device is already active, ignore the request.
This restores the original behaviour of the interface. The change was
probably an unintended side effect of
commit 66b37c6777c4 vga_switcheroo: split switching into two stages
which did not take into account to duplicate the !active check in the split-off
stage2.
Fix this by factoring that check out of stage1 into the debugfs_write routine.

FS_COW_FL and FS_NOCOW_FL were newly introduced to control per file
COW in btrfs, but FS_NOCOW_FL is sufficient.
The fact is we don't have corresponding BTRFS_INODE_COW flag.
COW is default, and FS_NOCOW_FL can be used to switch off COW for
a single file.
If we mount btrfs with nodatacow, a newly created file will be set with
the FS_NOCOW_FL flag. So to turn on COW for it, we can just clear the
FS_NOCOW_FL flag.

When a btrfs disk is created by mixed data & metadata option, it will have no

(Btrfs: fix OOPS of empty filesystem after balance) initializes space infos at

libata: fix oops when LPM is used with PMP
|
|
Shame on me! Commit b1dea800ac39 "tmpfs: fix race between umount and
writepage" fixed the advertized race, but introduced another: as even
its comment makes clear, we cannot safely rely on a peek at list_empty()
while holding no lock - until info->swapped is set, shmem_unuse_inode()
may delete any formerly-swapped inode from the shmem_swaplist, which
in this case would leave a swap area impossible to swapoff.
Although I don't relish taking the mutex every time, I don't care much
for the alternatives either; and at least the peek at list_empty() in
shmem_evict_inode() (a hotter path since most inodes would never have
been swapped) remains safe, because we already truncated the whole file.

if (num_registered_fb == FB_MAX)
return -ENXIO;
check _AFTER_ the call to do_remove_conflicting_framebuffers() as this
would (now in a safe way) allow a native driver to replace the
conflicting one even if all slots in registered_fb[] are taken.
This also prevents unregistering a framebuffer that is no longer
registered (vga16f will unregister at module unload time even if the
frame buffer had been unregistered earlier due to being found
conflicting).

When a register_framebuffer() call results in us removing old
conflicting framebuffers, the new registration_lock doesn't protect that
situation. And we can't just add the same locking to the function,
because these functions call each other: register_framebuffer() calls
remove_conflicting_framebuffers, which in turn calls
unregister_framebuffer for any conflicting entry.
In order to fix it, this just creates wrapper functions around all three
functions and makes the versions that actually do the work be called
"do_xxx()", leaving just the wrapper that gets the lock and calls the
worker function.
So the rule becomes simply that "do_xxxx()" has to be called with the
lock held, and now do_register_framebuffer() can just call
do_remove_conflicting_framebuffers(), and that in turn can call
_do_unregister_framebuffer(), and there is no deadlock, and we can hold
the registration lock over the whole sequence, fixing the races.
It also makes error cases simpler, and fixes one situation where we
would return from unregister_framebuffer() without releasing the lock,
pointed out by Bruno Prémont.

The rbd driver currently splits bios when they span an object boundary.
However, the blk_end_request expects the completions to roll up the results
in block device order, and the split rbd/ceph ops can complete in any
order. This patch adds a struct rbd_req_coll to track completion of split
requests and ensures that the results are passed back up to the block layer
in order.
This fixes errors where the file system gets completion of a read operation
that spans an object boundary before the data has actually arrived. The
bug is easily reproduced with iozone with a working set larger than
available RAM.

My Q67 / i7-2600 box has rev09 Sandy Bridge graphics. It hangs
instantly when GNOME loads and it hangs so hard the reset button
doesn't work. Setting i915.semaphore=0 fixes it.
Semaphores were disabled in a1656b9090f7 ("drm/i915: Disable GPU
semaphores by default") in 2.6.38 but were then re-enabled (by mistake?)
by the merge 47ae63e0c2e5 ("Merge branch 'drm-intel-fixes' into
drm-intel-next").
(It's worth noting that the offending change is i915_drv.c, which was
not marked as a conflict - although a 'git show --cc' on the merge does
show that neither parent had it set to 1)

With some combinations of arch/compiler (e.g. arm-linux-gcc) the sizeof
operator on structure returns value greater than expected. In cases when the
structure is used for mapping PDU fields it may lead to unexpected results
(such as holes and alignment problems in skb data). __packed prevents this
undesired behavior.

It's a hot function, and we're better off not mixing types in the mask
calculations. The compiler just ends up mixing 16-bit and 32-bit
operations, for no good reason.
So do everything in 'unsigned int' rather than mixing 'unsigned int'
masking with a 'umode_t' (16-bit) mode variable.
This, together with the parent commit (47a150edc2ae: "Cache user_ns in
struct cred") makes acl_permission_check() much nicer.

If !CONFIG_USERNS, have current_user_ns() defined to (&init_user_ns).
Get rid of _current_user_ns. This requires nsown_capable() to be
defined in capability.c rather than as static inline in capability.h,
so do that.
Request_key needs init_user_ns defined at current_user_ns if
!CONFIG_USERNS, so forward-declare that in cred.h if !CONFIG_USERNS
at current_user_ns() define.
Compile-tested with and without CONFIG_USERNS.
