USB on OMAP3 that fixes some longish-standing bugs around USB resets.
There are a couple of other changes that also add up line count a bit:
One is a long-standing bug with the keyboard layout on one of the PXA

power-off/reset button handling to be done in-kernel since relying on
userspace to handle it was fragile and awkward"

dcache: allow word-at-a-time name hashing with big-endian CPUs
When explicitly hashing the end of a string with the word-at-a-time
interface, we have to be careful which end of the word we pick up.
On big-endian CPUs, the upper-bits will contain the data we're after, so
ensure we generate our masks accordingly (and avoid hashing whatever
random junk may have been sitting after the string).
This patch adds a new dcache helper, bytemask_from_count, which creates
a mask appropriate for the CPU endianness.

Pull misc keyrings fixes from David Howells:
"These break down into five sets:
- A patch to error handling in the big_key type for huge payloads.
If the payload is larger than the "low limit" and the backing store
allocation fails, then big_key_instantiate() doesn't clear the
payload pointers in the key, assuming them to have been previously
cleared - but only one of them is.
Unfortunately, the garbage collector still calls big_key_destroy()
when sees one of the pointers with a weird value in it (and not
NULL) which it then tries to clean up.
- Three patches to fix the keyring type:
* A patch to fix the hash function to correctly divide keyrings off
from keys in the topology of the tree inside the associative
array. This is only a problem if searching through nested
keyrings - and only if the hash function incorrectly puts the a
keyring outside of the 0 branch of the root node.
* A patch to fix keyrings' use of the associative array. The
__key_link_begin() function initially passes a NULL key pointer
to assoc_array_insert() on the basis that it's holding a place in
the tree whilst it does more allocation and stuff.
This is only a problem when a node contains 16 keys that match at
that level and we want to add an also matching 17th. This should
easily be manufactured with a keyring full of keyrings (without
chucking any other sort of key into the mix) - except for (a)
above which makes it on average adding the 65th keyring.
* A patch to fix searching down through nested keyrings, where any
keyring in the set has more than 16 keyrings and none of the
first keyrings we look through has a match (before the tree
iteration needs to step to a more distal node).

- A patch to fix the big_key type's use of a shmem file as its
backing store causing audit messages and LSM check failures. This
is done by setting S_PRIVATE on the file to avoid LSM checks on the
file (access to the shmem file goes through the keyctl() interface
and so is gated by the LSM that way).
This isn't normally a problem if a key is used by the context that
generated it - and it's currently only used by libkrb5.

futex: move user address verification up to common code
When debugging the read-only hugepage case, I was confused by the fact
that get_futex_key() did an access_ok() only for the non-shared futex
case, since the user address checking really isn't in any way specific
to the private key handling.
Now, it turns out that the shared key handling does effectively do the
equivalent checks inside get_user_pages_fast() (it doesn't actually
check the address range on x86, but does check the page protections for
being a user page). So it wasn't actually a bug, but the fact that we
treat the address differently for private and shared futexes threw me
for a loop.
Just move the check up, so that it gets done for both cases. Also, use
the 'rw' parameter for the type, even if it doesn't actually matter any
more (it's a historical artifact of the old racy i386 "page faults from
kernel space don't check write protections").

Btrfs: don't miss skinny extent items on delayed ref head contention
Currently extent-tree.c:btrfs_lookup_extent_info() can miss the lookup
of skinny extent items. This can happen when the execution flow is the
following:
* We do an extent tree lookup and fail to find a skinny extent item;
* As a result, we attempt to see if a non-skinny extent item exists,
either by looking at previous item in the leaf or by doing another
full extent tree search;
* We have a transaction and then we check for a matching delayed ref
head in the transaction's delayed refs rbtree;
* We find such delayed ref head and then we try to lock it with a
call to mutex_trylock();
* The lock was contended so we jump to the label "again", which repeats
the extent tree search but for a non-skinny extent item, because we set
previously metadata variable to 0 and the search key to look for a
non-skinny extent-item;
* After the jump (and after releasing the transaction's delayed refs
lock), a skinny extent item might have been added to the extent tree
but we will miss it because metadata is set to 0 and the search key
is set for a non-skinny extent-item.
The fix here is to not reset metadata to 0 and to jump to the initial search
key setup if the delayed ref head is contended, instead of jumping directly
to the extent tree search label ("again").
This issue was found while investigating the issue reported at Bugzilla 64961.
David Sterba suspected this function was missing extent items, and that
this could be caused by the last change to this function, which was made
in the following patch:
[PATCH] Btrfs: optimize btrfs_lookup_extent_info()
(commit
74be9510876a66ad9826613ac8a526d26f9e7f01)
But in fact this issue already existed before, because after failing to find
a skinny extent item, the code set the search key for a non-skinny extent
item, and on contention of a matching delayed ref head it would not search
the extent tree for a skinny extent item anymore.

hwmon: (w83l768ng) Fix fan speed control range
The W83L786NG stores the fan speed on 4 bits while the sysfs interface

to map it to the device range, and scale up the value read from the
device before presenting it to the user. The reserved register nibble

ALSA: hda - Add static DAC/pin mapping for
AD1986A codec
AD1986A codec is a pretty old codec and has really many hidden
restrictions. One of such is that each DAC is dedicated to certain
pin although there are possible connections. Currently, the generic
parser tries to assign individual DACs as much as possible, and this
lead to two bad situations: connections where the sound actually
doesn't work, and connections conflicting other channels.
We may fix this by trying to find the best connections more harder,
but as of now, it's easier to give some hints for paired DAC/pin
connections and honor them if available, since such a hint is needed
only for specific codecs (right now only
AD1986A, and there will be
unlikely any others in future).

However, HDMI simple_playback_build_controls() as used by old VIA and

In case the card has other codecs that have HDMI outputs, the controls

ARM: OMAP2+: omap_device: add fail hook for runtime_pm when bad data is detected
Due to the cross dependencies between hwmod for automanaged device
information for OMAP and dts node definitions, we can run into scenarios
where the dts node is defined, however it's hwmod entry is yet to be
added. In these cases:
a) omap_device does not register a pm_domain (since it cannot find
hwmod entry).
b) driver does not know about (a), does a pm_runtime_get_sync which
never fails
c) It then tries to do some operation on the device (such as read the
revision register (as part of probe) without clock or adequate OMAP
generic PM operation performed for enabling the module.
This causes a crash such as that reported in:
https://bugzilla.kernel.org/show_bug.cgi?id=66441

will not function without the OMAP's power automanagement. Hence, when
we hit a fail condition (due to hwmod entries not present or other
similar scenario), fail at pm_domain level due to lack of data, provide
enough information for it to be fixed, however, it allows for the driver

ALSA: memalloc.h - fix wrong truncation of dma_addr_t
When running a 32bit kernel the hda_intel driver is still reporting
a 64bit dma_mask if the HW supports it.
From sound/pci/hda/hda_intel.c:
/* allow 64bit DMA address if supported by H/W */
if ((gcap & ICH6_GCAP_64OK) && !pci_set_dma_mask(pci, DMA_BIT_MASK(64)))
pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(64));
else {
pci_set_dma_mask(pci, DMA_BIT_MASK(32));
pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(32));
}
which means when there is a call to dma_alloc_coherent from
snd_malloc_dev_pages a machine address bigger than 32bit can be returned.
This can be true in particular if running the 32bit kernel as a pv dom0
under the Xen Hypervisor or PAE on bare metal.
The problem is that when calling setup_bdle to program the BLE the
dma_addr_t returned from the dma_alloc_coherent is wrongly truncated
from snd_sgbuf_get_addr if running a 32bit kernel:
static inline dma_addr_t snd_sgbuf_get_addr(struct snd_dma_buffer *dmab,
size_t offset)
{
struct snd_sg_buf *sgbuf = dmab->private_data;
dma_addr_t addr = sgbuf->table[offset >> PAGE_SHIFT].addr;
addr &= PAGE_MASK;
return addr + offset % PAGE_SIZE;
}
where PAGE_MASK in a 32bit kernel is zeroing the upper 32bit af addr.
Without this patch the HW will fetch the 32bit truncated address,
which is not the one obtained from dma_alloc_coherent and will result
to a non working audio but can corrupt host memory at a random location.
The current patch apply to

avr32: favr-32: clk_round_rate() can return a zero upon error
Treat both negative and zero return values from clk_round_rate() as
errors. This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather than a
signed type, since some clock sources can generate rates higher than
(2^31)-1 Hz.
Eventually, when calling clk_round_rate(), only a return value of zero
will be considered a error. All other values will be considered valid
rates. The comparison against values less than 0 is kept to preserve
the correct behavior in the meantime.

However, __setup_offsets also initializes the length fields, and that should

PowerNV, kdump base is set to 512M resulting kdump to fail while allocating

powerpc: Fix PTE page address mismatch in pgtable ctor/dtor
In pte_alloc_one(), pgtable_page_ctor() is passed an address that has
not been converted by page_address() to the newly allocated PTE page.
When the PTE is freed, __pte_free_tlb() calls pgtable_page_dtor()
with an address to the PTE page that has been converted by page_address().
The mismatch in the PTE's page address causes pgtable_page_dtor() to access
invalid memory, so resources for that PTE (such as the page lock) is not
properly cleaned up.
On PPC32, only SMP kernels are affected.
On PPC64, only SMP kernels with 4K page size are affected.
This bug was introduced by commit
d614bb041209fd7cb5e4b35e11a7b2f6ee8f62b8
"powerpc: Move the pte free routines from common header".
On a preempt-rt kernel, a spinlock is dynamically allocated for each
PTE in pgtable_page_ctor(). When the PTE is freed, calling
pgtable_page_dtor() with a mismatched page address causes a memory leak,
as the pointer to the PTE's spinlock is bogus.
On mainline, there isn't any immediately obvious symptoms, but the
problem still exists here.

a repeated SOFTRESET e.g. enable_sysc(). This is true for OMAP3 like

so the the SOFTRESET bit in SYSCONFIG is not automatically cleared.
It is not a problem for OMAP4 like platforms that indicate RESET
completion by clearing the SOFTRESET bit in the SYSCONFIG register.
This repeated SOFTRESET is undesired and was the root cause of
USB host issues on OMAP3 platforms when hwmod was allowed to do the

ARM: OMAP4+: hwmod data: Don't prevent RESET of USB Host module
Without this, the USB devices are sometimes not detected on OMAP4 Panda
with u-boot v2013.10.
Unlike what the comment states, errata i660 does not state that we
can't RESET the USB host module. Instead it states that RESET is the
only way to recover from a deadlock situation.
RESET ensures that the module is in a known good state irrespective
of what bootloader does with the module, so it must be done at boot.
