Merge commit 'v3.3-rc1' into stable/for-linus-fixes-3.3
* commit 'v3.3-rc1': (9775 commits) Linux 3.3-rc1 x86, syscall: Need __ARCH_WANT_SYS_IPC for 32 bits qnx4: don't leak ->BitMap on late failure exits qnx4: reduce the insane nesting in qnx4_checkroot() qnx4: di_fname is an array, for crying out loud... KEYS: Permit key_serial() to be called with a const key pointer keys: fix user_defined key sparse messages ima: fix cred sparse warning uml: fix compile for x86-64 MPILIB: Add a missing ENOMEM check tpm: fix (ACPI S3) suspend regression nvme: fix merge error due to change of 'make_request_fn' fn type xen: using EXPORT_SYMBOL requires including export.h gpio: tps65910: Use correct offset for gpio initialization acpi/apei/einj: Add extensions to EINJ from rev 5.0 of acpi spec intel_idle: Split up and provide per CPU initialization func ACPI processor: Remove unneeded variable passed by acpi_processor_hotadd_init V2 tg3: Fix single-vector MSI-X code openvswitch: Fix multipart datapath dumps. ipv6: fix per device IP snmp counters ...
