vmxnet3's netpoll driver is incorrectly coded. It directly calls
vmxnet3_do_poll, which is the driver internal napi poll routine. As the netpoll
controller method doesn't block real napi polls in any way, there is a potential
for race conditions in which the netpoll controller method and the napi poll
method run concurrently. The result is data corruption causing panics such as this
one recently observed:

The fix is to do as other drivers do, and have the poll controller call the top

This was an optimization that made memcpy type benchmarks a little
faster on ancient (Circa 1998) IDT Winchip CPUs. In real-life
workloads, it wasn't even noticable, and I doubt anyone is running
benchmarks on 16 year old silicon any more.
Given this code has likely seen very little use over the last decade,
let's just remove it.

ASoC: Fixes for v3.14
A few things here:
- Avoid memory leaks in error cases with DPCM, this code has never been
that well tested in mainline due to the lack of mainline drivers but
we now have one queued for the merge window!
- Fix the N810 audio driver to load when booted with DT since the
platform was converted to DT during the merge window.
- Fixes for initialisation of some MFD drivers that are probably unused
in mainline

With TX VLAN offload enabled the source MAC address for frames sent using the
VLAN interface is currently set to the address of the real interface. This is
wrong since the VLAN interface may be configured with a different address.
The bug was introduced in commit 2205369a314e12fcec4781cc73ac9c08fc2b47de
("vlan: Fix header ops passthru when doing TX VLAN offload.").
This patch sets the source address before calling the create function of the
real interface.

Current netback uses gso_type to check whether the skb contains
gso offload, and this is wrong. Gso_size is the right one to
check gso existence, and gso_type is only used to check gso type.
Some skbs contains nonzero gso_type and zero gso_size, current
netback would treat these skbs as gso and create wrong response
for this. This also causes ssh failure to domu from other server.

Adds support for HFSX 'HasFolderCount' flag and a corresponding
'folderCount' field in folder records. (For reference see
HFS_FOLDERCOUNT and kHFSHasFolderCountBit/kHFSHasFolderCountMask in
Apple's source code.)
Ignoring subfolder count leads to fs errors found by Mac:
...
Checking catalog hierarchy.
HasFolderCount flag needs to be set (id = 105)
(It should be 0x10 instead of 0)
Incorrect folder count in a directory (id = 2)
(It should be 7 instead of 6)
...
Steps to reproduce:
Format with "newfs_hfs -s /dev/diskXXX".
Mount in Linux.
Create a new directory in root.
Unmount.
Run "fsck_hfs /dev/diskXXX".
The patch handles directory creation, deletion, and rename.

The expected logic of proc_map_files_get_link() is either to return 0
and initialize 'path' or return an error and leave 'path' uninitialized.
By the time dname_to_vma_addr() returns 0 the corresponding vma may have
already be gone. In this case the path is not initialized but the
return value is still 0. This results in 'general protection fault'
inside d_path().
Steps to reproduce:
CONFIG_CHECKPOINT_RESTORE=y
fd = open(...);
while (1) {
mmap(fd, ...);
munmap(fd, ...);
}

We received several reports of bad page state when freeing CMA pages
previously allocated with alloc_contig_range:
BUG: Bad page state in process Binder_A pfn:63202
page:d21130b0 count:0 mapcount:1 mapping: (null) index:0x7dfbf
page flags: 0x40080068(uptodate|lru|active|swapbacked)
Based on the page state, it looks like the page was still in use. The
page flags do not make sense for the use case though. Further debugging
showed that despite alloc_contig_range returning success, at least one
page in the range still remained in the buddy allocator.
There is an issue with isolate_freepages_block. In strict mode (which
CMA uses), if any pages in the range cannot be isolated,
isolate_freepages_block should return failure 0. The current check
keeps track of the total number of isolated pages and compares against
the size of the range:
if (strict && nr_strict_required > total_isolated)
total_isolated = 0;
After taking the zone lock, if one of the pages in the range is not in
the buddy allocator, we continue through the loop and do not increment
total_isolated. If in the last iteration of the loop we isolate more
than one page (e.g. last page needed is a higher order page), the check
for total_isolated may pass and we fail to detect that a page was
skipped. The fix is to bail out if the loop immediately if we are in
strict mode. There's no benfit to continuing anyway since we need all
pages to be isolated. Additionally, drop the error checking based on
nr_strict_required and just check the pfn ranges. This matches with
what isolate_freepages_range does.

GFP_THISNODE is for callers that implement their own clever fallback to
remote nodes. It restricts the allocation to the specified node and
does not invoke reclaim, assuming that the caller will take care of it
when the fallback fails, e.g. through a subsequent allocation request
without GFP_THISNODE set.
However, many current GFP_THISNODE users only want the node exclusive
aspect of the flag, without actually implementing their own fallback or
triggering reclaim if necessary. This results in things like page
migration failing prematurely even when there is easily reclaimable
memory available, unless kswapd happens to be running already or a
concurrent allocation attempt triggers the necessary reclaim.
Convert all callsites that don't implement their own fallback strategy
to __GFP_THISNODE. This restricts the allocation a single node too, but
at the same time allows the allocator to enter the slowpath, wake
kswapd, and invoke direct reclaim if necessary, to make the allocation
happen when memory is full.

we clear an already cleared value but do it without locking, so just
remove that. The other is for a data leak - we leak two bytes of kernel
memory out over the air in QoS NULL frames because those don't get a
sequence number assigned in the TX path."

Our write() system call has always been atomic in the sense that you get
the expected thread-safe contiguous write, but we haven't actually
guaranteed that concurrent writes are serialized wrt f_pos accesses, so
threads (or processes) that share a file descriptor and use "write()"
concurrently would quite likely overwrite each others data.
This violates POSIX.1-2008/SUSv4 Section XSI 2.9.7 that says:
"2.9.7 Thread Interactions with Regular File Operations
All of the following functions shall be atomic with respect to each
other in the effects specified in POSIX.1-2008 when they operate on
regular files or symbolic links: [...]"
and one of the effects is the file position update.
This unprotected file position behavior is not new behavior, and nobody
has ever cared. Until now. Yongzhi Pan reported unexpected behavior to
Michael Kerrisk that was due to this.
This resolves the issue with a f_pos-specific lock that is taken by
read/write/lseek on file descriptors that may be shared across threads
or processes.

i=`keyctl newring _ses @s`
keyctl link @s $i
The problem is that search_nested_keyrings() sees two keyrings that have
matching type and description, so keyring_compare_object() returns true.
s_n_k() then passes the key to the iterator function -
keyring_detect_cycle_iterator() - which *should* check to see whether this is
the keyring of interest, not just one with the same name.
Because assoc_array_find() will return one and only one match, I assumed that
the iterator function would only see an exact match or never be called - but
the iterator isn't only called from assoc_array_find()...
The oops looks something like this:
kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
invalid opcode: 0000 [#1] SMP
...
RIP: keyring_detect_cycle_iterator+0xe/0x1f
...
Call Trace:
search_nested_keyrings+0x76/0x2aa
__key_link_check_live_key+0x50/0x5f
key_link+0x4e/0x85
keyctl_keyring_link+0x60/0x81
SyS_keyctl+0x65/0xe4
tracesys+0xdd/0xe2
The fix is to make keyring_detect_cycle_iterator() check that the key it
has is the key it was actually looking for rather than calling BUG_ON().
A testcase has been included in the keyutils testsuite for this:

The pci shutdown handler added in:
bnx2: Add pci shutdown handler
commit 25bfb1dd4ba3b2d9a49ce9d9b0cd7be1840e15ed
created a shutdown down sequence without chip reset if the device was
never brought up. This can cause the firmware to shutdown the PHY
prematurely and cause MMIO read cycles to be unresponsive. On some
systems, it may generate NMI in the bnx2's pci shutdown handler.
The fix is to tell the firmware not to shutdown the PHY if there was
no prior chip reset.

Pull thermal fixes from Zhang Rui:
"Specifics:
- Update the help text of INT3403 Thermal driver, which was not
friendly to users. From Zhang Rui.
- The "type" sysfs attribute of x86_pkg_temp_thermal registered
thermal zones includes an instance number, which makes the
thermal-to-hwmon bridge fails to group them all in a single hwmon
device. Fixed by Jean Delvare.
- The hwmon device registered by x86_pkg_temp_thermal driver is
redundant because the temperature value reported by
x86_pkg_temp_thermal is already reported by the coretemp driver.
Fixed by Jean Delvare.
- Fix a problem that the cooling device can not be updated properly
if it is initialized at max cooling state. From Ni Wade.
- Fix a problem that OF registered thermal zones are running without
thermal governors. From Zhang Rui.
- Commit beeb5a1e0ef7 ("thermal: rcar-thermal: Enable driver
compilation with COMPILE_TEST") broke build on archs wihout io
memory. Thus make it depend on HAS_IOMEM to bypass build failures.
Fixed by Richard Weinberger"
