Updating the hysteresis value when updating the critical temperature limit
was following the rule of 'least surprise'. However, it had the undesirable

invalid hysteresis values if the resulting hysteresis was too large. In such
cases the resulting hysteresis ended up changed anyway, which again defeats
the purpose. So drop that code and document the new behavior.

Pull ACPI and power management fixes from Rafael Wysocki:
"Still fixing regressions (partly by reverting commits that broke
things for people), fixing other stable-candidate bugs and adding some
blacklist entries for ACPI video and _OSI.
Two ACPICA regression fixes (one recent and one for a 3.14 commit), a
fix for an ACPI-related regression in TPM (introduced in 3.14), a
revert of the ACPI AC driver conversion in 3.13 that went wrong for an
unknown reason, two reverts of commits that attempted to remove an old
user space interface in /proc and broke some utilities, in 3.13 too, a
fix for a CPU hotplug bug in the ACPI processor driver (stable
material), two (stable candidate) fixes for intel_pstate and a few new
blacklist entries, mostly for systems that shipped with Windows 8.
Specifics:
- ACPICA fix for a stale pointer access introduced by a recent commit
in the XSDT validation code from Lv Zheng.
- ACPICA fix for the default value of the command line switch to
favor 32-bit FADT addresses (in case there's a conflict between a
64-bit and a 32-bit address). The previous default was that the
32-bit version would take precedence and we tried to change it to
the other way around and it didn't work. From Lv Zheng.
- A TPM commit related to ACPI _DSM in 3.14 caused the driver to
refuse to load if a specific _DSM was missing and that broke resume
from system suspend on Chromebooks that require the TPM hardware to
be restored to a working state during resume by the OS. Restore
the old behavior to load the driver if the _DSM in question is not
present, but prevent it from using the feature the _DSM is for.
- ACPI AC driver conversion in 3.13 broke thermal management on at
least one machine and has to be reverted. From Guenter Roeck.
- Two reverts of 3.13 commits that attempted to remove the old ACPI
battery interface in /proc, but turned out to break some utilities
still using that interface. From Lan Tianyu.
- ACPI processor driver fix to prevent acpi_processor_add() from
modifying the CPU device's .offline field which leads to breakage
if the initial online of the CPU fails. From Igor Mammedov.
- Two intel_pstate fixes, one to take a BayTrail documentation update
into account and one to avoid forcing the maximum P-state on init
which causes CPU PM trouble on systems with P-states coordination
when one of the CPU cores is initialized after an offline/online
cycle triggered by user space. Both stable candidates, from Dirk
Brandewie.
- Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520
from Aaron Lu.
- Two new ACPI video blacklist entries for machines shipping with
Win8 that need to use native backlight so that it can be controlled
in a usual way (which doesn't work otherwise due bugs in the ACPI

sysfs: make sure read buffer is zeroed
13c589d5b0ac ("sysfs: use seq_file when reading regular files")
switched sysfs from custom read implementation to seq_file to enable
later transition to kernfs. After the change, the buffer passed to
->show() is acquired through seq_get_buf(); unfortunately, this
introduces a subtle behavior change. Before the commit, the buffer
passed to ->show() was always zero as it was allocated using
get_zeroed_page(). Because seq_file doesn't clear buffers on
allocation and neither does seq_get_buf(), after the commit, depending
on the behavior of ->show(), we may end up exposing uninitialized data
to userland thus possibly altering userland visible behavior and
leaking information.
Fix it by explicitly clearing the buffer.

target: fix memory leak on XCOPY
On each processed XCOPY command, two "kmalloc-512" memory objects are
leaked. These represent two allocations of struct xcopy_pt_cmd in
target_core_xcopy.c.
The reason for the memory leak is that the cmd_kref field is not
initialized (thus, it is zero because the allocations were done with
kzalloc). When we decrement zero kref in target_put_sess_cmd, the result
is not zero, thus target_release_cmd_kref is not called.
This patch fixes the bug by moving kref initialization from
target_get_sess_cmd to transport_init_se_cmd (this function is called from
target_core_xcopy.c, so it will correctly initialize cmd_kref). It can be
easily verified that all code that calls target_get_sess_cmd also calls
transport_init_se_cmd earlier, thus moving kref_init shouldn't introduce
any new problems.

libceph: fix corruption when using page_count 0 page in rbd

corruption. The bug report can be found here:
https://github.com/zfsonlinux/spl/issues/241
http://tracker.ceph.com/issues/7790
The reason is that ZFS will send pages with page_count 0 into rbd, which in
turns send them to tcp_sendpage. However, tcp_sendpage cannot deal with
page_count 0, as it will do get_page and put_page, and erroneously free the
page.
This type of issue has been noted before, and handled in iscsi, drbd,
etc. So, rbd should also handle this. This fix address this issue by fall back
to slower sendmsg when page_count 0 detected.
