83c1b31794 ramoops: fix compile failure on parisc
Fixes this:

  drivers/char/ramoops.c: In function 'ramoops_init':
  drivers/char/ramoops.c:221: error: implicit declaration of function 'IS_ERR'
  drivers/char/ramoops.c:222: error: implicit declaration of function 'PTR_ERR'

If it actually builds on other platforms, it's probably getting
linux/err.h via some other #include.

59ed2bb274 ext2: remove duplicate 'ext2_get_acl()' define
When commit 4e34e719e4 ("fs: take the ACL checks to common code")
changed the xyz_check_acl() functions into the more natural
xyz_get_acl() interface, we grew two copies of the

  #define ext2_get_acl	NULL

define for the non-acl case.

Remove the extra one.

2a11c8ea20 kconfig: Introduce IS_ENABLED(), IS_BUILTIN() and IS_MODULE()
Replace the config_is_*() macros with a variant that allows for grepping
for usage of CONFIG_* options in the code. Usage:

  if (IS_ENABLED(CONFIG_NUMA))

or

  #if IS_ENABLED(CONFIG_NUMA)

The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y'
or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if
the option is 'm'. Only boolean and tristate options are supported.

029e9f7366 cpupower: Do detect IDA (opportunistic processor performance) via cpuid
IA32-Intel Devel guide Volume 3A - 14.3.2.1
-------------------------------------------
...
Opportunistic processor performance operation can be disabled by setting bit 38 of
IA32_MISC_ENABLES. This mechanism is intended for BIOS only. If
IA32_MISC_ENABLES[38] is set, CPUID.06H:EAX[1] will return 0.

Better detect things via cpuid, this cleans up the code a bit
and the MSR parts were not working correctly anyway.

7fe2f6399a cpupowerutils - cpufrequtils extended with quite some features
CPU power consumption vs performance tuning is no longer
limited to CPU frequency switching anymore: deep sleep states,
traditional dynamic frequency scaling and hidden turbo/boost
frequencies are tied close together and depend on each other.
The first two exist on different architectures like PPC, Itanium and
ARM, the latter (so far) only on X86. On X86 the APU (CPU+GPU) will
only run most efficiently if CPU and GPU has proper power management
in place.

Users and Developers want to have *one* tool to get an overview what
their system supports and to monitor and debug CPU power management
in detail. The tool should compile and work on as many architectures
as possible.

Once this tool stabilizes a bit, it is intended to replace the
Intel-specific tools in tools/power/x86

drivers/net/pcmcia/smc91c92_cs.c:812:12: warning: ‘j’ may be used uninitialized in this function

However, "j" is only used in a branch which has the same condition as
a previous branch, where j is set, e.g.

	int j;

	if (CONDITION)
	    j = VALUE

	...

	if (CONDITION)
	   printk(j)

Still, avoid this warning, as it is easy to circumvent.

14b9f27886 pcmcia: add PCMCIA_DEVICE_MANF_CARD_PROD_ID3
This is needed to match wireless cards with Intersil firmware that have
ID 0x0156:0x0002 and the third ID "Version 01.02".  Such cards are
currently matched by orinoco_cs, which doesn't support WPA.  They should
be matched by hostap_cs.

The first and the second product ID vary widely, so there are few users
with some particular IDs.  Of those, very few can submit a patch for
hostap_cs or write a useful bugreport.  It's still important to support
their hardware properly.

With PCMCIA_DEVICE_MANF_CARD_PROD_ID3, it should be possible to cover
the remaining Intersil based designs that kept the numeric ID and the
"version" of the reference design.

b2987a5e05 eCryptfs: Unlock keys needed by ecryptfsd
Fixes a regression caused by b5695d0463

Kernel keyring keys containing eCryptfs authentication tokens should not
be write locked when calling out to ecryptfsd to wrap and unwrap file
encryption keys. The eCryptfs kernel code can not hold the key's write
lock because ecryptfsd needs to request the key after receiving such a
request from the kernel.

Without this fix, all file opens and creates will timeout and fail when
using the eCryptfs PKI infrastructure. This is not an issue when using
passphrase-based mount keys, which is the most widely deployed eCryptfs
configuration.

6d101c588f hwmon: (lm90) Make SA56004 detection more robust
With a device ID register value of 0, the SA56004 detection is rather
weak. Check several other register too to confirm the detection, as we
do for other supported devices.

a095f687f1 hwmon: (lm90) Simplify handling of extended local temp register
The optional extended local temperature register can never have
address 0, as this address is already used by another register. Thus
we can get rid of flag LM90_HAVE_LOCAL_EXT and simply rely on
reg_local_ext being non-zero to determine if a given chip has this
extension or not. This makes the code more simple.

6f183d33a0 hwmon: (pmbus) Add support for peak attributes
Most PMBus devices provide manufacturer specific commands to read low and/or
high peak values for some or all of its sensors.

To support providing those values as lowest/highest attributes to the user,
introduce virtual PMBus commands. Those commands reside outside the normal
command set and have to be implemented in device specific code, which map the
virtual commands to device specific commands.

c6bfb767e4 hwmon: (pmbus) Strengthen check for status register existence
With virtual register page support, it is now possible that the status register
on virtual pages does not exist or is itself virtual. To take this into account
when creating alarm attributes, generate those attributes only if the status
register on the respective page is known to exist.

9c1ed8941d hwmon: (pmbus) Add support for virtual pages
Some PMBus chips have non-standard sensor registers. An easy way to
support such sensors is to introduce virtual pages and map the non-standard
registers into standard registers on an extra page.

For this to work, the code verifying if the configured number of pages exists
has to be removed. Since a wrong number of pages can only be configured in a
front-end driver, this should not have a practical impact since the resulting
errors should be found during development and testing.

Also, functions to read the chip status while checking if a command register
exists must be modified to no longer set the page register before reading the
status, since the physical page associated with the checked register may not
exist. This does not make a functional difference since the page was already set
when the attempt to read the register was made.
