  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

  material), two (stable candidate) fixes for intel_pstate and a few new

  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

     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

10 years agosysfs: make sure read buffer is zeroed

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.
