Bartlomiej Zolnierkiewicz 075affcbe0 ide: preserve Host Protected Area by default (v2)
From the perspective of most users of recent systems, disabling Host
Protected Area (HPA) can break vendor RAID formats, GPT partitions and
risks corrupting firmware or overwriting vendor system recovery tools.

Unfortunately the original (kernels < 2.6.30) behavior (unconditionally
disabling HPA and using full disk capacity) was introduced at the time
when the main use of HPA was to make the drive look small enough for the
BIOS to allow the system to boot with large capacity drives.

Thus to allow the maximum compatibility with the existing setups (using
HPA and partitioned with HPA disabled) we automically disable HPA if
any partitions overlapping HPA are detected.  Additionally HPA can also
be disabled using the "nohpa" module parameter (i.e. "ide_core.nohpa=0.0"
to disable HPA on /dev/hda).

v2:
Fix ->resume HPA support.

While at it:
- remove stale "idebus=" entry from Documentation/kernel-parameters.txt

Steven Rostedt 2af15d6a44 ftrace: add kernel command line function filtering
When using ftrace=function on the command line to trace functions
on boot up, one can not filter out functions that are commonly called.

This patch adds two new ftrace command line commands.

  ftrace_notrace=function-list
  ftrace_filter=function-list

Where function-list is a comma separated list of functions to filter.
The ftrace_notrace will make the functions listed not be included
in the function tracing, and ftrace_filter will only trace the functions
listed.

These two act the same as the debugfs/tracing/set_ftrace_notrace and
debugfs/tracing/set_ftrace_filter respectively.

The simple glob expressions that are allowed by the filter files can also
be used by the command line interface.

	ftrace_notrace=rcu*,*lock,*spin*

Will not trace any function that starts with rcu, ends with lock, or has
the word spin in it.

Note, if the self tests are enabled, they may interfere with the filtering
set by the command lines.

Eric Paris 5789ba3bd0 IMA: Minimal IMA policy and boot param for TCB IMA policy
The IMA TCB policy is dangerous.  A normal use can use all of a system's
memory (which cannot be freed) simply by building and running lots of
executables.  The TCB policy is also nearly useless because logging in as root
often causes a policy violation when dealing with utmp, thus rendering the
measurements meaningless.

There is no good fix for this in the kernel.  A full TCB policy would need to
be loaded in userspace using LSM rule matching to get both a protected and
useful system.  But, if too little is measured before userspace can load a real
policy one again ends up with a meaningless set of measurements.  One option
would be to put the policy load inside the initrd in order to get it early
enough in the boot sequence to be useful, but this runs into trouble with the
LSM.  For IMA to measure the LSM policy and the LSM policy loading mechanism
it needs rules to do so, but we already talked about problems with defaulting
to such broad rules....

IMA also depends on the files being measured to be on an FS which implements
and supports i_version.  Since the only FS with this support (ext4) doesn't
even use it by default it seems silly to have any IMA rules by default.

This should reduce the performance overhead of IMA to near 0 while still
letting users who choose to configure their machine as such to inclue the
ima_tcb kernel paramenter and get measurements during boot before they can
load a customized, reasonable policy in userspace.

Andi Kleen 1dcdb5a9e7 oprofile: re-add force_arch_perfmon option
This re-adds the force_arch_perfmon option that was in the original
arch perfmon patchkit. Originally this was rejected in favour
of a generalized perfmon=name option, but it turned out implementing
the later in a reliable way is hard (and it would have been easy
to crash the kernel if a user gets it wrong)

But now Atom and Core i7 support being readded a user would
need to update their oprofile userland to beyond 0.9.4 to use oprofile again
on Atom or Core i7.

To avoid this problem readd the force_arch_perfmon option.

Luca Tettamanti 7e90560c50 ACPI: acpi_enforce_resource=strict by default
Enforce strict resource checking - disallowing access by native
drivers to IO ports and memory regions claimed by ACPI firmware.

The patch is mainly aimed to block native hwmon drivers from touching
monitoring chips that ACPI thinks it own.

If this causes a regression, boot with "acpi_enforce_resources=lax"
which was the previous default.

Paul Mundt eeee7853c4 sh: Add a command line option for disabling I/O trapping.
This adds a 'noiotrap' kernel command line option to permit disabling of
I/O trapping. This is mostly useful for running on emulators where the
physical device limitations are not an issue.

Paul Moore 58bfbb51ff selinux: Remove the "compat_net" compatibility code
The SELinux "compat_net" is marked as deprecated, the time has come to
finally remove it from the kernel.  Further code simplifications are
likely in the future, but this patch was intended to be a simple,
straight-up removal of the compat_net code.
