processors. A whole bunch of new PCIe device ids, but otherwise
pretty much the same as Haswell.

One of the two callers passes an unintialized pointer as "fmt" and
expects it to be set to NULL if there is no format string. Let's make
this function work as expected.

When inspecting the pivot_root and the current mount expiry logic I
realized that pivot_root fails to clear like mount move does.
Add the missing line in case someone does the interesting feat of
moving an expirable submount. This gives a strong guarantee that root
of the filesystem tree will never expire.

Clear MNT_LOCKED in the callers of copy_tree except copy_mnt_ns, and
collect_mounts. In copy_mnt_ns it is necessary to create an exact
copy of a mount tree, so not clearing MNT_LOCKED is important.
Similarly collect_mounts is used to take a snapshot of the mount tree
for audit logging purposes and auditing using a faithful copy of the
tree is important.
This becomes particularly significant when we start setting MNT_LOCKED
on rootfs to prevent it from being unmounted.

Which in practice is totally uninteresting. Only the global root user can
do it, and it is just a stupid thing to do.
However that is no excuse to allow a silly way to oops the kernel.
We can avoid this silly problem by setting MNT_LOCKED on the rootfs
mount point and thus avoid needing any special cases in the unmount
code.

Forced unmount affects not just the mount namespace but the underlying
superblock as well. Restrict forced unmount to the global root user
for now. Otherwise it becomes possible a user in a less privileged
mount namespace to force the shutdown of a superblock of a filesystem
in a more privileged mount namespace, allowing a DOS attack on root.

- MNT_NODEV should be irrelevant except when reading back mount flags,
no longer specify MNT_NODEV on remount.
- Test MNT_NODEV on devpts where it is meaningful even for unprivileged mounts.
- Add a test to verify that remount of a prexisting mount with the same flags
is allowed and does not change those flags.
- Cleanup up the definitions of MS_REC, MS_RELATIME, MS_STRICTATIME that are used
when the code is built in an environment without them.
- Correct the test error messages when tests fail. There were not 5 tests
that tested MS_RELATIME.

Now that remount is properly enforcing the rule that you can't remove
nodev at least sandstorm.io is breaking when performing a remount.
It turns out that there is an easy intuitive solution implicitly
add nodev on remount when nodev was implicitly added on mount.

bio integrity handling is broken on a system with LVM layered atop a
DIF/DIX SCSI drive because device mapper clones the bio, modifies the
clone, and sends the clone to the lower layers for processing.
However, the clone bio has bi_vcnt == 0, which means that when the sd
driver calls bio_integrity_process to attach DIX data, the
for_each_segment_all() call (which uses bi_vcnt) returns immediately
and random garbage is sent to the disk on a disk write. The disk of
course returns an error.
Therefore, teach bio_integrity_process() to use bio_for_each_segment()
to iterate the bio_vecs, since the per-bio iterator tracks which
bio_vecs are associated with that particular bio. The integrity
handling code is effectively part of the "driver" (it's not the bio
owner), so it must use the correct iterator function.
v2: Fix a compiler warning about abandoned local variables. This
patch supersedes "block: bio_integrity_process uses wrong bio_vec
iterator". Patch applies against 3.18-rc6.

When using the algif_skcipher, the following call sequence causess a
re-initialization:
1. sendmsg with ALG_SET_OP and iov == NULL, iovlen == 0 (i.e
initializing the cipher, but not sending data)
2. sendmsg with msg->msg-controllen == 0 and iov != NULL (using the initalized
cipher handle by sending data)
In step 2, the cipher operation type (encryption or decryption) is reset
to always decryption, because the local variable of enc is put into
ctx->enc as ctx->user is still zero.
The same applies when all send data is processed and ctx->used falls to
zero followed by user space to send new data.
This patch changes the behavior to only reset the cipher operation type
(and the IV) if such configuration request is received.

Until this patch, dumping the monitor data could be done only
for PCIe external (DRAM) mode in 7000 HW family. This patch
allows to pull the monitor data also on other families, and
also to pull the monitor data if an internal buffer is used.

Commit 14e85c0e69d5 ("gpio: remove gpio_descs global array") changed
gpio_to_desc()'s behavior to return NULL not only for GPIOs numbers
not in the valid range, but also for all GPIOs whose controller has not
been probed yet. Although this behavior is more correct (nothing hints
that these GPIO numbers will be populated later), this affects
gpio_request() and gpio_request_one() which call gpiod_request() with a
NULL descriptor, causing it to return -EINVAL instead of the expected
-EPROBE_DEFER for a non-probed GPIO.
gpiod_request() is only called with a descriptor obtained from
gpio_to_desc() from these two functions, so address the issue there.
Other ways to obtain GPIOs rely on well-defined mappings and can thus
return -EPROBE_DEFER only for relevant GPIOs, and are thus not affected
by this issue.

LRC object does not need to be mapped into the GGTT when dumping. A side-effect
of this patch is that a compiler warning goes away (not checking return value
of i915_gem_obj_ggtt_pin).
v2: Broke out individual context dumping into a new function as the indentation
was getting a bit crazy. Added notification of contexts with no gem object for
debugging purposes. Removed unnecessary pin_pages and unpin_pages, replaced
with explicit get_pages for the context object as there may be no backing store
allocated at this time (Comment for get_pages says "Ensure that the associated
pages are gathered from the backing storage and pinned into our object").
Improved error checking - get_pages and get_page are checked for failure.

Haswell moved the TOLM/TOHM registers to a different device and offset.
The sb_edac driver accounted for the change of device, but not for the
new offset. There was also a typo in the constant to fill in the low
26 bits (was 0x1ffffff, should be 0x3ffffff).
This resulted in a bogus value for the top of low memory:
EDAC DEBUG: get_memory_layout: TOLM: 0.032 GB (0x0000000001ffffff)
which would result in EDAC refusing to translate addresses for
errors above the bogus value and below 4GB:

I added a paragraph on choosing label names, and updated the example
code to use a better label name. I also cleaned up the example code to
more modern style by moving the allocation out of the initializer and
changing the NULL check.
Perhaps the most common type of error handling bug in the kernel is "one
err bugs". CodingStyle already says that we should "avoid nesting" by
using error labels and one err style error handling tends to have
multiple indent levels, so this was already bad style. But I've added a
new paragraph explaining how to avoid one err bugs by using multiple
error labels which is, hopefully, more clear.
