commit 2023c610dc54a4f4130b0494309a9bd668ca3df8 upstream.
This patch (as1271) affects when new devices get linked into their
bus's list of devices. Currently this happens after probing, and it
doesn't happen at all if probing fails. Clearly this is wrong,
because at that point quite a few symbolic links have already been
created in sysfs. We are committed to adding the device, so it should
be linked into the bus's list regardless.
In addition, this needs to happen before the uevent announcing the new
device gets issued. Otherwise user programs might try to access the
device before it has been added to the bus.
To fix both these problems, the patch moves the call to
klist_add_tail() forward from bus_attach_device() to bus_add_device().
Since bus_attach_device() now does nothing but probe for drivers, it
has been renamed to bus_probe_device(). And lastly, the kerneldoc is
updated.

netfilter: nf_nat: fix inverted logic for persistent NAT mappings
Upstream commit cce5a5c3:
Kernel 2.6.30 introduced a patch [1] for the persistent option in the
netfilter SNAT target. This is exactly what we need here so I had a quick look
at the code and noticed that the patch is wrong. The logic is simply inverted.
The patch below fixes this.
Also note that because of this the default behavior of the SNAT target has
changed since kernel 2.6.30 as it now ignores the destination IP in choosing
the source IP for nating (which should only be the case if the persistent
option is set).

commit 119e7a22bb70d84849384e5113792cd45afa4f85 upstream.
This improves patch fa6963b24 so that perf.data stuff that has
been dumped as root can be read (annotate/report) by a user
without the use of the --force.
Rationale is that root has plenty of ways to screw us (usually)
that do not require twisted schemes involving specially
crafting a perf.data.

(cherry picked from commit dc7e795e3dd2a763e5ceaa1615f307e808cf3932)
This reverts commit 6c20e1442bb1c62914bb85b7f4a38973d2a423ba.
To my understanding, it became obsolete with the advent of the more
robust check in mmu_alloc_roots (89da4ff17f). Moreover, it prevents
the conceptually safe pattern
1. set sregs
2. register mem-slots
3. run vcpu
by setting a sticky triple fault during step 1.

commit 202c4675c55ddf6b443c7e057d2dff6b42ef71aa upstream.
Commit ac89a9174 ("pty: don't limit the writes to 'pty_space()' inside
'pty_write()'") removed the pty_space() checking, in order to let the
regular tty buffer code limit the buffering itself.
That was all good, but as a subtle side effect it meant that we'd be
doing a tty_wakeup() even in the case where the buffers were all filled
up, and didn't actually make any progress on the write.
Which sounds innocuous, but it interacts very badly with the ppp_async
code, which has an infinite loop in ppp_async_push() that tries to push
out data to the tty. When we call tty_wakeup(), that loop ends up
thinking that progress was made (see the subtle interactions between
XMIT_WAKEUP and 'tty_stuffed' for details). End result: one unhappy ppp
user.
Fixed by noticing when tty_insert_flip_string() didn't actually do
anything, and then not doing any more processing (including, very much
not calling tty_wakeup()).

The length of the to-copy data structure is currently stored in
a signed integer. However many comparisons are done with sizeof(..)
which is unsigned. It's more suitable for this variable to be unsigned
to make these comparisons more naturally right.

fixed upstream in commit b7058842c940ad2c08dd829b21e5c92ebe3b8758 in a different way
The ax25 code tried to use
if (optlen < sizeof(int))
return -EINVAL;
as a security check against optlen being negative (or zero) in the
set socket option.
Unfortunately, "sizeof(int)" is an unsigned property, with the
result that the whole comparison is done in unsigned, letting
negative values slip through.
This patch changes this to
if (optlen < (int)sizeof(int))
return -EINVAL;
so that the comparison is done as signed, and negative values
get properly caught.

commit 31b239ad1ba7225435e13f5afc47e48eb674c0cc upstream.
Commit a5bfc4714b3f01365aef89a92673f2ceb1ccf246 dropped explicit
pci_intx() manipulation from ahci because it seemed unnecessary and
ahci doesn't seem to be the right place to be tweaking it if it were.
This was largely okay but there are exceptions. There was one on an
embedded platform which was fixed via firmware and now bko#14124
reports it on a HP DL320.
http://bugzilla.kernel.org/show_bug.cgi?id=14124
I still think this isn't something libata drivers should be caring
about (the only ones which are calling pci_intx() explicitly are
libata ones and one other driver) but for now reverting the change
seems to be the right thing to do.

commit 481a8199142c050b72bff8a1956a49fd0a75bbe0 upstream.
When using nanosleep() in an userspace application we get a ratelimit warning
NOHZ: local_softirq_pending 08
for 10 times.
The echo of CAN frames is done from process context and softirq context only.
Therefore the usage of netif_rx() was wrong (for years).
This patch replaces netif_rx() with netif_rx_ni() which has to be used from
process/softirq context. It also adds a missing comment that can_send() must
no be used from hardirq context.

commit 886e3b7fe6054230c89ae078a09565ed183ecc73 upstream.
On setting up the callback to the client, we attempt to use the same
authentication flavor the client did. We find an rpc cred to use by
calling rpcauth_lookup_credcache(), which assumes that the given
authentication flavor has a credentials cache. However, this is not
required to be true--in particular, auth_null does not use one.
Instead, we should call the auth's lookup_cred() method.
Without this, a client attempting to mount using nfsv4 and auth_null
triggers a null dereference.

commit e517a5e97080bbe52857bd0d7df9b66602d53c4d upstream.
Ever since we enabled GEM, the pre-9xx chipsets (particularly 865) have had
serious stability issues. Back in May a wbinvd was added to the DRM to
work around much of the problem. Some failure remained -- easily visible
by dragging a window around on an X -retro desktop, or by looking at bugzilla.
The chipset flush was on the right track -- hitting the right amount of
memory, and it appears to be the only way to flush on these chipsets, but the
flush page was mapped uncached. As a result, the writes trying to clear the
writeback cache ended up bypassing the cache, and not flushing anything! The
wbinvd would flush out other writeback data and often cause the data we wanted
to get flushed, but not always. By removing the setting of the page to UC
and instead just clflushing the data we write to try to flush it, we get the
desired behavior with no wbinvd.
This exports clflush_cache_range(), which was laying around and happened to
basically match the code I was otherwise going to copy from the DRM.

drm_ht_remove_item() does not handle removing an absent item and the hlist

This also fixes the mishandling of a partially constructed offset which
leaves pointers initialized after freeing them along the
i915_gem_create_mmap_offset() error paths.
In particular this should fix the oops found here:

commit 665d7662d15441b4b3e54131a9418a1a198d0d31 upstream.
According to the specifications, an instrument should not return more data in a
DEV_DEP_MSG_IN urb than requested. However, some instruments can send more
than requested. This could cause the kernel to write the extra data past the
end of the buffer provided by read().
Fix this by checking that the value of the TranserSize field is not larger than
the urb itself and not larger than the size of the userspace buffer. Also
correctly decrement the remaining size of the buffer when userspace read()s
more than USBTMC_SIZE_IOBUFFER.

commit a4304f2d5a3823deea894026ec95e43b33912357 upstream.
The tty_operation chars_in_buffer() is not allowed to return a negative
value to signal an error. Corrects the problem flagged by commit
23198fda7182969b619613a555f8645fdc3dc334, "tty: fix chars_in_buffers".

commit ec3815c3e14dc68d49428e6505ae99e86e5dd067 upstream.
Some devices from the OpenDCC project are missing in the list
of the FTDI PIDs. These PIDs are listed at
http://www.opendcc.de/elektronik/usb/opendcc_usb.html
(Sorry for the german only page.)
This patch adds the three missing devices.

commit 23af51ecfb04ff65bae51bd8e2270f4449abc789 upstream.
The M29W128G Numonyx flash devices are intolerant to any 0xFF command:
in the Cfi_util.c the function cfi_qry_mode_off() (that resets the device
after the autoselect mode) must have a 0xF0 command after the 0xFF command.
This fix solves also the cause of the fixup_M29W128G_write_buffer() fix,
that can be removed now.
The following patch applies to 2.6.30 kernel.

commit ebd5a74db74ee2db833d43ea35108a4be9cab42f upstream.
The previous implementation breaks the dts binding "mtd-physmap.txt". This
implementation fixes the issue by checking the availability of the reg
property instead of the name property.
