Dmitry Kasatkin 68adcad570 lib: MPILIB Kconfig description update
It was reported that description of the MPILIB_EXTRA is confusing.
Indeed it was copy-paste typo. It is fixed here.

Mimi Zohar 6ac6172a93 encrypted-keys: fix rcu and sparse messages
Enabling CONFIG_PROVE_RCU and CONFIG_SPARSE_RCU_POINTER resulted in
"suspicious rcu_dereference_check() usage!" and "incompatible types
in comparison expression (different address spaces)" messages.

Access the masterkey directly when holding the rwsem.

Changelog v1:
- Use either rcu_read_lock()/rcu_derefence_key()/rcu_read_unlock()
or remove the unnecessary rcu_derefence() - David Howells

Mimi Zohar ee0b31a25a keys: fix trusted/encrypted keys sparse rcu_assign_pointer messages
Define rcu_assign_keypointer(), which uses the key payload.rcudata instead
of payload.data, to resolve the CONFIG_SPARSE_RCU_POINTER message:
"incompatible types in comparison expression (different address spaces)"

David Howells efde8b6e16 KEYS: Add missing smp_rmb() primitives to the keyring search code
Add missing smp_rmb() primitives to the keyring search code.

When keyring payloads are appended to without replacement (thus using up spare
slots in the key pointer array), an smp_wmb() is issued between the pointer
assignment and the increment of the key count (nkeys).

There should be corresponding read barriers between the read of nkeys and
dereferences of keys[n] when n is dependent on the value of nkeys.

Greg Kroah-Hartman e032d80774 mce: fix warning messages about static struct mce_device
When suspending, there was a large list of warnings going something like:

	Device 'machinecheck1' does not have a release() function, it is broken and must be fixed

This patch turns the static mce_devices into dynamically allocated, and
properly frees them when they are removed from the system.  It solves
the warning messages on my laptop here.

Eric Miao 012f3b9118 hwmon: (max1111) Change sysfs interface to in[0-3]_input in millivolts
This patch fixed the inconsistent max1111 sysfs interface as pointed
out by Jean Delvare:

    It was pointed to me that the max1111 driver doesn't implement the
    standard sysfs interface for hwmon drivers (as described in
    Documentation/hwmon/sysfs-interface). It exports files adc[0-3]_in,
    which
    aren't part of the standard interface. Presumably these should be
    renamed to in[0-3]_input. Renaming them is probably not sufficient
    though, as I see no scaling done in the driver. As the MAX1111 chip has
    a documented full scale of 2.048V, I take it that the LSB of the ADC
    has a weight of 8 mV. Exporting raw register values to user-space is
    not OK.

H. Peter Anvin 2dac8e54f9 random: Adjust the number of loops when initializing
When we are initializing using arch_get_random_long() we only need to
loop enough times to touch all the bytes in the buffer; using
poolwords for that does twice the number of operations necessary on a
64-bit machine, since in the random number generator code "word" means
32 bits.

Theodore Ts'o 3e88bdff1c random: Use arch-specific RNG to initialize the entropy store
If there is an architecture-specific random number generator (such as
RDRAND for Intel architectures), use it to initialize /dev/random's
entropy stores.  Even in the worst case, if RDRAND is something like
AES(NSA_KEY, counter++), it won't hurt, and it will definitely help
against any other adversaries.

Ohad Ben-Cohen 1a51a0ce17 ARM: OMAP3: fix build on !CONFIG_IOMMU_API
omap3isp depends on CONFIG_IOMMU_API, so avoid registering its
device (and defining its configuration structs) on !CONFIG_IOMMU_API.

This is generally nice to have, but more importantly, it fixes:

arch/arm/plat-omap/include/plat/iommu.h: In function 'dev_to_omap_iommu':
arch/arm/plat-omap/include/plat/iommu.h:135: error: 'struct
dev_archdata' has no member named 'iommu'
arch/arm/mach-omap2/devices.c: In function 'omap3_init_camera':
arch/arm/mach-omap2/devices.c:222: error: 'struct dev_archdata' has no
member named 'iommu'
make[1]: *** [arch/arm/mach-omap2/devices.o] Error 1
make: *** [arch/arm/mach-omap2] Error 2

Which happens because while setting up the omap3isp device we try
to access the (now nonexistent) iommu member of dev_archdata.

Compile tested with omap2plus_defconfig on today's:

  kernel/module.c:1024:2: error: implicit declaration of function ‘module_flags_taint’ [-Werror=implicit-function-declaration]
