Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris: "This is basically a maintenance update for the TPM driver and EVM/IMA" Fix up conflicts in lib/digsig.c and security/integrity/ima/ima_main.c * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (45 commits) tpm/ibmvtpm: build only when IBM pseries is configured ima: digital signature verification using asymmetric keys ima: rename hash calculation functions ima: use new crypto_shash API instead of old crypto_hash ima: add policy support for file system uuid evm: add file system uuid to EVM hmac tpm_tis: check pnp_acpi_device return code char/tpm/tpm_i2c_stm_st33: drop temporary variable for return value char/tpm/tpm_i2c_stm_st33: remove dead assignment in tpm_st33_i2c_probe char/tpm/tpm_i2c_stm_st33: Remove __devexit attribute char/tpm/tpm_i2c_stm_st33: Don't use memcpy for one byte assignment tpm_i2c_stm_st33: removed unused variables/code TPM: Wait for TPM_ACCESS tpmRegValidSts to go high at startup tpm: Fix cancellation of TPM commands (interrupt mode) tpm: Fix cancellation of TPM commands (polling mode) tpm: Store TPM vendor ID TPM: Work around buggy TPMs that block during continue self test tpm_i2c_stm_st33: fix oops when i2c client is unavailable char/tpm: Use struct dev_pm_ops for power management TPM: STMicroelectronics ST33 I2C BUILD STUFF ...
