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)"

Replace the rcu_assign_pointer() calls in encrypted/trusted keys with
rcu_assign_keypointer().

David Howells 633e804e89 KEYS: Add an RCU payload dereference macro
Add an RCU payload dereference macro as this seems to be a common piece of code
amongst key types that use RCU referenced payloads.

Jesper Juhl 5403110943 trusted keys: Fix a memory leak in trusted_update().
One failure path in security/keys/trusted.c::trusted_update() does
not free 'new_p' while the others do. This patch makes sure we also free
it in the remaining path (if datablob_parse() returns different from
Opt_update).
