Enable setting security contexts on rootfs inodes.

rootfs (ramfs) can support setting of security contexts
by userspace due to the vfs fallback behavior of calling
the security module to set the in-core inode state
for security.* attributes when the filesystem does not
provide an xattr handler.  No xattr handler required
as the inodes are pinned in memory and have no backing
store.

This is useful in allowing early userspace to label individual
files within a rootfs while still providing a policy-defined
default via genfs.

msm: kgsl: Don't hold process list global mutex in process private create

Don't hold process list global mutex for long. Instead make
use of process specific spin_lock() to serialize access
to process private structure while creating it. Holding
process list global mutex could lead to deadlocks as other
functions depend on it.
