b5d27718f3 Raid5 should update rdev->sectors after reshape
The raid5 md device is created by the disks which we don't use the total size. For example,
the size of the device is 5G and it just uses 3G of the devices to create one raid5 device.
Then change the chunksize and wait reshape to finish. After reshape finishing stop the raid
and assemble it again. It fails.
mdadm -CR /dev/md0 -l5 -n3 /dev/loop[0-2] --size=3G --chunk=32 --assume-clean
mdadm /dev/md0 --grow --chunk=64
wait reshape to finish
mdadm -S /dev/md0
mdadm -As
The error messages:
[197519.814302] md: loop1 does not have a valid v1.2 superblock, not importing!
[197519.821686] md: md_import_device returned -22

After reshape the data offset is changed. It selects backwards direction in this condition.
In function super_1_load it compares the available space of the underlying device with
sb->data_size. The new data offset gets bigger after reshape. So super_1_load returns -EINVAL.
rdev->sectors is updated in md_finish_reshape. Then sb->data_size is set in super_1_sync based
on rdev->sectors. So add md_finish_reshape in end_reshape.

7cfdfdc82a libata: Cleanup ata_read_log_page()
The warning message "READ LOG DMA EXT failed, trying unqueued" in
ata_read_log_page() as well as the macro name ATA_HORKAGE_NO_NCQ_LOG
are confusing: the command READ LOG DMA EXT is not an queued NCQ command
unless it is encapsulated in a RECEIVE FPDMA QUEUED command.
From ACS-4 READ LOG DMA EXT description:

"The device processes the READ LOG DMA EXT command in the NCQ feature
set environment (see 4.13.6) if the READ LOG DMA EXT command is
encapsulated in a RECEIVE FPDMA QUEUED command (see 7.30) with the
inputs encapsulated as shown in 7.23.6."

To avoid confusion, fix the warning messsage to mention switching to PIO and
not "unqueued" and rename the macro ATA_HORKAGE_NO_NCQ_LOG to
ATA_HORKAGE_NO_DMA_LOG.

ff0fa73247 btrfs: nowait aio: Correct assignment of pos
Assigning pos for usage early messes up in append mode, where the pos is
re-assigned in generic_write_checks(). Assign pos later to get the
correct position to write from iocb->ki_pos.

Since check_can_nocow also uses the value of pos, we shift
generic_write_checks() before check_can_nocow(). Checks with IOCB_DIRECT
are present in generic_write_checks(), so checking for IOCB_NOWAIT is
enough.

Also, put locking sequence in the fast path.

This fixes a user visible bug, as reported:

"apparently breaks several shell related features on my system.
In zsh history stopped working, because no new entries are added
anymore.
I fist noticed the issue when I tried to build mplayer. It uses a shell
script to generate a help_mp.h file:
[...]

 % echo "foo" >> test
 % echo "foo" >> test
 % cat test

1e2a516e89 powerpc/kexec: Fix radix to hash kexec due to IAMR/AMOR
This patch fixes a crash seen while doing a kexec from radix mode to
hash mode. Key 0 is special in hash and used in the RPN by default, we
set the key values to 0 today. In radix mode key 0 is used to control
supervisor<->user access. In hash key 0 is used by default, so the
first instruction after the switch causes a crash on kexec.

Commit 3b10d0095a ("powerpc/mm/radix: Prevent kernel execution of
user space") introduced the setting of IAMR and AMOR values to prevent
execution of user mode instructions from supervisor mode. We need to
clean up these SPR's on kexec.

0f107573da Input: gpio_keys - handle the missing key press event in resume phase
The GPIO key press event might be missed in the resume phase, if the key
had been released before the system had been resumed to the stage that it
could capture the press event. So we simulate the wakeup key press event
in case the key had been released by the time we got interrupt handler
to run.

d3e3b7eac8 afs: Add metadata xattrs
Add xattrs to allow the user to get/set metadata in lieu of having pioctl()
available.  The following xattrs are now available:

 - "afs.cell"

   The name of the cell in which the vnode's volume resides.

 - "afs.fid"

   The volume ID, vnode ID and vnode uniquifier of the file as three hex
   numbers separated by colons.

 - "afs.volume"

   The name of the volume in which the vnode resides.

For example:

	# getfattr -d -m ".*" /mnt/scratch
	getfattr: Removing leading '/' from absolute path names
	# file: mnt/scratch
	afs.cell="mycell.myorg.org"
	afs.fid="10000b:1:1"
	afs.volume="scratch"

fd2498211a afs: Ignore AFS_ACE_READ and AFS_ACE_WRITE for directories
The AFS_ACE_READ and AFS_ACE_WRITE permission bits should not
be used to make access decisions for the directory itself.  They
are meant to control access for the objects contained in that
directory.

Reading a directory is allowed if the AFS_ACE_LOOKUP bit is set.
This would cause an incorrect access denied error for a directory
with AFS_ACE_LOOKUP but not AFS_ACE_READ.

The AFS_ACE_WRITE bit does not allow operations that modify the
directory.  For a directory with AFS_ACE_WRITE but neither
AFS_ACE_INSERT nor AFS_ACE_DELETE, this would result in trying
operations that would ultimately be denied by the server.

f991af3daa mqueue: fix a use-after-free in sys_mq_notify()
The retry logic for netlink_attachskb() inside sys_mq_notify()
is nasty and vulnerable:

1) The sock refcnt is already released when retry is needed
2) The fd is controllable by user-space because we already
   release the file refcnt

so we when retry but the fd has been just closed by user-space
during this small window, we end up calling netlink_detachskb()
on the error path which releases the sock again, later when
the user-space closes this socket a use-after-free could be
triggered.

Setting 'sock' to NULL here should be sufficient to fix it.

9ffd93852f microblaze: move generic-y of exported headers to uapi/asm/Kbuild
Since commit fcc8487d47 ("uapi: export all headers under uapi
directories"), all (and only) headers under uapi directories are
exported, but asm-generic wrappers are still exceptions.

To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.

With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.

For microblaze, "generic-y += siginfo.h" is doubled in asm/Kbuild and
uapi/asm/Kbuild.  So, the one in the former can be simply removed.
