Current code calls omap4430_phy_init() twice in usb_musb_init().
Calling omap4430_phy_init() once is enough.
This patch removes the first omap4430_phy_init() call, which using an
uninitialized pointer as parameter.
This patch elimates below build warning:
arch/arm/mach-omap2/usb-musb.c: In function 'usb_musb_init':
arch/arm/mach-omap2/usb-musb.c:141: warning: 'dev' may be used uninitialized in this function

Looks like 2600 kHz rate does not work reliably on 2430,
so just use the 100 kHz rate.

Remove OMAP4_USBC1_ICUSB_PWRDNZ_MASK during enable/disable PWRDNZ mode for
MMC1_PBIAS and associated extended-drain MMC1 I/O cell. This is in accordance
with the control module programming guide. This fixes a bug where if trying to
use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be
affected by a changing SDMMC1_VDDS.
Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever
SDMMC1_VDDS ramps up/down or changes for cell protection purposes.
MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore
they can operate independently.

David reported:
Attached below is a watered-down version of rt/tst-cpuclock2.c from
GLIBC. Just build it with "gcc -o test test.c -lpthread -lrt" or
similar.
Run it several times, and you will see cases where the main thread
will measure a process clock difference before and after the nanosleep
which is smaller than the cpu-burner thread's individual thread clock
difference. This doesn't make any sense since the cpu-burner thread
is part of the top-level process's thread group.
I've reproduced this on both x86-64 and sparc64 (using both 32-bit and
64-bit binaries).
For example:
[davem@boricha build-x86_64-linux]$ ./test
process: before(0.001221967) after(0.498624371) diff(497402404)
thread: before(0.000081692) after(0.498316431) diff(498234739)
self: before(0.001223521) after(0.001240219) diff(16698)
[davem@boricha build-x86_64-linux]$
The diff of 'process' should always be >= the diff of 'thread'.
I make sure to wrap the 'thread' clock measurements the most tightly
around the nanosleep() call, and that the 'process' clock measurements
are the outer-most ones.

This is due to us using p->se.sum_exec_runtime in
thread_group_cputime() where we iterate the thread group and sum all
data. This does not take time since the last schedule operation (tick
or otherwise) into account. We can cure this by using
task_sched_runtime() at the cost of having to take locks.
This also means we can (and must) do away with
thread_group_sched_runtime() since the modified thread_group_cputime()
is now more accurate and would deadlock when called from
thread_group_sched_runtime().
Aside of that it makes the function safe on 32 bit systems. The old
code added t->se.sum_exec_runtime unprotected. sum_exec_runtime is a
64bit value and could be changed on another cpu at the same time.

The commit a810364a0424c297242c6c66071a42f7675a5568
ALSA: hda - Handle -1 as invalid position, too
caused a regression on some machines that require the position-buffer
instead of LPIB, e.g. resulting in noises with mic recording with
PulseAudio.
This patch fixes the detection by delaying the test at the timing as
same as 3.0, i.e. doing the position check only when requested in
azx_position_ok().

__find_resource() incorrectly returns a resource window which overlaps
an existing allocated window. This happens when the parent's
resource-window spans 0x00000000 to 0xffffffff and is entirely allocated
to all its children resource-windows.
__find_resource() looks for gaps in resource allocation among the
children resource windows. When it encounters the last child window it
blindly tries the range next to one allocated to the last child. Since
the last child's window ends at 0xffffffff the calculation overflows,
leading the algorithm to believe that any window in the range 0x0000000
to 0xfffffff is available for allocation. This leads to a conflicting
window allocation.

Apple Quad G5 has some oddity in it's device-tree which causes the new
generic matching code to fail to relate nodes for PCI-E devices below U4
with their respective struct pci_dev. This breaks graphics on those
machines among others.
This fixes it using a quirk which copies the node pointer from the host
bridge for the root complex, which makes the generic code work for the
children afterward.

Commit d5767c53535a ("bootup: move 'usermodehelper_enable()' to the end
of do_basic_setup()") moved 'usermodehelper_enable()' to end of
do_basic_setup() to after the initcalls. But then I get failed to let
uvesafb work on my computer, and lose the splash boot.
So maybe we could start usermodehelper_enable a little early to make
some task work that need eary init with the help of user mode.
[ I would *really* prefer that initcalls not call into user space - even
the real 'init' hasn't been execve'd yet, after all! But for uvesafb
it really does look like we don't have much choice.
I considered doing this when we mount the root filesystem, but
depending on config options that is in multiple places. We could do
the usermode helper enable as a rootfs_initcall()..
So I'm just using wang yanqing's trivial patch. It's not wonderful,
but it's simple and should work. We should revisit this some day,
though. - Linus ]

Wrong pointer is being passed for raw data sanity checking, when parsing
sample event.
This ends up with invalid event and perf record being stuck in
__perf_session__process_events function during processing build IDs
(process_buildids function).
Following command hangs up in my setup:
./perf record -e raw_syscalls:sys_enter ls
The fix is to use proper pointer to the raw data instead of the 'u'
union.

In the OF 'translations' property, the template TTEs in the mappings
never specify the executable bit. This is the case even though some
of these mappings are for OF's code segment.
Therefore, we need to force the execute bit on in every mapping.
This problem can only really trigger on Niagara/sun4v machines and the
history behind this is a little complicated.
Previous to sun4v, the sun4u TTE entries lacked a hardware execute
permission bit. So OF didn't have to ever worry about setting
anything to handle executable pages. Any valid TTE loaded into the
I-TLB would be respected by the chip.
But sun4v Niagara chips have a real hardware enforced executable bit
in their TTEs. So it has to be set or else the I-TLB throws an
instruction access exception with type code 6 (protection violation).
We've been extremely fortunate to not get bitten by this in the past.
The best I can tell is that the OF's mappings for it's executable code
were mapped using permanent locked mappings on sun4v in the past.
Therefore, the fact that we didn't have the exec bit set in the OF
translations we would use did not matter in practice.
Thanks to Greg Onufer for helping me track this down.

In the rds_iw_mr_pool struct the free_pinned field keeps track of
memory pinned by free MRs. While this field is incremented properly
upon allocation, it is never decremented upon unmapping. This would
cause the rds_rdma module to crash the kernel upon unloading, by
triggering the BUG_ON in the rds_iw_destroy_mr_pool function.
This change keeps track of the MRs that become unpinned, so that
free_pinned can be decremented appropriately.

This ties nodatasum fixup in scrub together with raid repair patches. While
both series are working fine alone, scrub will report uncorrectable errors
if they occur in a nodatasum extent *and* the page is in the page cache.
Previously, we would have triggered readpage to find good data and do the
repair. However, readpage wouldn't read anything in the case where the page
is up to date in the cache. So, we simply take that good data we have and
call repair_io_failure directly (unless the page in the cache is dirty).

The raid-retry code in inode.c can be generalized so that it works for
metadata as well. Thus, this patch moves it to extent_io.c and makes the
raid-retry code a raid-repair code.
Repair works that way: Whenever a read error occurs and we have more
mirrors to try, note the failed mirror, and retry another. If we find a
good one, check if we did note a failure earlier and if so, do not allow
the read to complete until after the bad sector was written with the good
data we just fetched. As we have the extent locked while reading, no one
can change the data in between.

The error correction code wants to make sure that only the bad mirror is
rewritten. Thus, we need to know which mirror is the bad one. I did not
find a more apropriate field than bi_bdev. But I think using this is fine,
because it is modified by the block layer, anyway, and should not be read
after the bio returned.

The block layer modifies bio->bi_bdev and bio->bi_sector while working on
the bio, they do _not_ come back unmodified in the completion callback.
To call add_page, we need at least some bi_bdev set, which is why the code
was working, previously. With this patch, we use the latest_bdev from
fsinfo instead of the leftover in the bio. This gives us the possibility to
use the bi_bdev field for another purpose.

btrfs_bio is a bio abstraction able to split and not complete after the last

This removes a FIXME comment and introduces the first part of nodatasum
fixup: It gets the corresponding inode for a logical address and triggers a

Once we have on-the-fly error correction our error will be automatically

EXTENT_DAMAGED flag, making scrub report that error as "corrected" instead
of "uncorrectable" eventually.

The IEEE 1588 standard defines two kinds of messages, event and general

using UDP transport, two separate ports are used for the two message

The BPF designed to recognize event messages incorrectly classifies L2
general messages as event messages. This commit fixes the issue by

Event messages are be distinguished from general messages by testing

Doing it just before starting to call into cpu_idle() made a sick kind
of sense only because the original bug we fixed (see commit
288d5abec831: "Boot up with usermodehelper disabled") was about problems
with some scheduler data structures not being initialized, and they had
better be initialized at that point.
But it really didn't make any other conceptual sense, and doing it after
the initial "schedule()" call for the idle thread actually opened up a
race: what if the main initialization thread did everything without
needing to sleep, and got all the way into user land too? Without
actually having scheduled back to the idle thread?
Now, in normal circumstances that doesn't ever happen, but it looks like
Richard Cochran triggered exactly that on his ARM IXP4xx machines:
"I have some ARM IXP4xx based machines that use the two on chip MAC
ports (aka NPEs). The NPE needs a firmware in order to function.
Ever since the following commit [that 288d5abec831 one], it is no
longer possible to bring up the interfaces during the init scripts."
with a call trace showing an ioctl coming from user space. Richard says:
"The init is busybox, and the startup script does mount, syslogd, and
then ifup, so that all can go by quickly."
The fix is to move the usermodehelper_enable() into the main 'init'
thread, and just put it after we've done all our initcalls. By then,
everything really should be up, but we've obviously not actually started
the user-mode portion of init yet.

The incremental map updates have a record for each pg_temp mapping that is
to be add/updated (len > 0) or removed (len == 0). The old code was
written as if the updates were a complete enumeration; that was just wrong.
Update the code to remove 0-length entries and drop the rbtree traversal.

Storing the struct temp_data pointer allocated from create_core_data()
when returning an error has the potential of leaving around a pointer
to freed memory. Reset it to NULL for error returns.

With recent change "hwmon: (coretemp) don't use kernel assigned CPU
number as platform device ID", the microcode check is now running on
random CPU. Fix that by checking the microcode before creating the
platform device rather than at probe time.
Also avoid calling TO_PHYS_ID(cpu) twice in the same function, it's
expensive.

A kernel crash is observed when a mounted ext3/ext4 filesystem is
physically removed. The problem is that blk_cleanup_queue() frees up
some resources eg by calling elevator_exit(), which are not checked for
in normal operation. So we should rather move these calls to the
destructor function blk_release_queue() as at that point all remaining
references are gone. However, in doing so we have to ensure that any
externally supplied queue_lock is disconnected as the driver might free
up the lock after the call of blk_cleanup_queue(),
