commit b399151cb48db30ad1e0e93dd40d68c6d007b637 upstream. x86_mask is a confusing name which is hard to associate with the processor's stepping. Additionally, correct an indent issue in lib/cpu.c.

2017-03-30hwrng: geode - Revert managed API changesPrarit Bhargava
commit 8c75704ebcac2ffa31ee7bcc359baf701b52bf00 upstream. After commit e9afc746299d ("hwrng: geode - Use linux/io.h instead of asm/io.h") the geode-rng driver uses devres with pci_dev->dev to keep track of resources, but does not actually register a PCI driver. This results in the following issues: 1. The driver leaks memory because the driver does not attach to a device. The driver only uses the PCI device as a reference. devm_*() functions will release resources on driver detach, which the geode-rng driver will never do. As a result, 2. The driver cannot be reloaded because there is always a use of the ioport and region after the first load of the driver.

commit 69db7009318758769d625b023402161c750f7876 upstream. After commit 31b2a73c9c5f ("hwrng: amd - Migrate to managed API"), the amd-rng driver uses devres with pci_dev->dev to keep track of resources, but does not actually register a PCI driver. This results in the following issues: 1. The message WARNING: CPU: 2 PID: 621 at drivers/base/dd.c:349 driver_probe_device+0x38c is output when the i2c_amd756 driver loads and attempts to register a PCI driver. The PCI & device subsystems assume that no resources have been registered for the device, and the WARN_ON() triggers since amd-rng has already do so. 2. The driver leaks memory because the driver does not attach to a device. The driver only uses the PCI device as a reference. devm_*() functions will release resources on driver detach, which the amd-rng driver will never do. As a result, 3.

2016-09-22hwrng: omap - Only fail if pm_runtime_get_sync returns < 0Dave Gerlach
Currently omap-rng checks the return value of pm_runtime_get_sync and reports failure if anything is returned, however it should be checking if ret < 0 as pm_runtime_get_sync return 0 on success but also can return 1 if the device was already active which is not a failure case. Only values < 0 are actual failures.

2016-09-13hwrng: core - Allocate memory during module initPrasannaKumar Muralidharan
In core rng_buffer and rng_fillbuf is allocated in hwrng_register only once and it is freed during module exit. This patch moves allocating rng_buffer and rng_fillbuf from hwrng_register to rng core's init. This avoids checking whether rng_buffer and rng_fillbuf was allocated from every hwrng_register call.

2016-04-05hwrng: exynos - Runtime suspend device after initKrzysztof Kozlowski
The driver uses pm_runtime_put_noidle() after initialization so the device might remain in active state if the core does not read from it (the read callback contains regular runtime put). The put_noidle() was chosen probably to avoid unneeded suspend and resume cycle after the initialization. However for this purpose autosuspend is enabled so it is safe to runtime put just after the initialization.

Drivers: - Support T5/M5, T7/M7 SPARC CPUs in n2 hwrng driver. - Add PIC32 hwrng driver. - Support BCM6368 in bcm63xx hwrng driver. - Pack structs for 32-bit compat users in qat. - Use crypto engine in omap-aes. - Add support for sama5d2x SoCs in atmel-sha. - Make atmel-sha available again. - Make sahara hashing available again. - Make ccp hashing available again. - Make sha1-mb available again. - Add support for multiple devices in ccp. - Improve DMA performance in caam. - Add hashing support to rockchip" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (116 commits) crypto: qat - remove redundant arbiter configuration crypto: ux500 - fix checks of error code returned by devm_ioremap_resource() crypto: atmel - fix checks of error code returned by devm_ioremap_resource() crypto: qat - Change the definition of icp_qat_uof_regtype hwrng: exynos - use __maybe_unused to hide pm functions crypto: ccp - Add abstraction for device-specific calls crypto: ccp - CCP versioning support crypto: ccp - Support for multiple CCPs crypto: ccp - Remove check for x86 family and model crypto: ccp - memset request context to zero during import lib/mpi: use "static inline" instead of "extern inline" lib/mpi: avoid assembler warning hwrng: bcm63xx - fix non device tree compatibility crypto: testmgr - allow rfc3686 aes-ctr variants in fips mode. crypto: qat - The AE id should be less than the maximal AE number lib/mpi: Endianness fix crypto: rockchip - add hash support for crypto engine in rk3288 crypto: xts - fix compile errors crypto: doc - add skcipher API documentation crypto: doc - update AEAD AD handling ...
2016-03-11hwrng: exynos - use __maybe_unused to hide pm functionsArnd Bergmann
The exynos random driver uses #ifdef to check for CONFIG_PM, but then uses SIMPLE_DEV_PM_OPS, which leaves the references out when CONFIG_PM_SLEEP is not defined, so we get a warning with PM=y && PM_SLEEP=n: drivers/char/hw_random/exynos-rng.c:166:12: error: 'exynos_rng_suspend' defined but not used [-Werror=unused-function] drivers/char/hw_random/exynos-rng.c:171:12: error: 'exynos_rng_resume' defined but not used [-Werror=unused-function] This removes the incorrect #ifdef and instead uses a __maybe_unused annotation to let the compiler know it can silently drop the function definition.
