sanitize count used for kmem_alloc size.
Hmm, who uses CIOCNGSESSION, CIOCNFSESSION, CIOCNCRYPTM or CIOCNFKEYM?
--
sanitize in CIOCNCRYPTM and initialize comp_alg in CIOCNGSESSION
--
must release cap->cc_lock before calling cap->cc_newsession() because of spinlock.
--
refactor crypto_newsession() like FreeBSD.
--
support multiple encryption drivers (port from FreeBSD).
--
Divide crp_devflags from crp_flags to write exclusively.
CRYPTO_F_DQRETQ(new name is CRYPTODEV_F_RET) is used by cryptodev.c only.
It should be divided to other member.
--
Reduce crypto_ret_q_mtx lock regions.
crypto.c does not access the members of crp when the crp is in crp_q or
crp_ret_q. Furthermore, crp_q and crp_ret_q are protected by each mutex,
so the members of crp is not shared. That means crp_flags is not required
mutex in crypto.c.
--
fix cryptosoft.c:r1.51 mistake. swcrypto_attach() must not be called from module_init_class().
swcrypto_attach() will call softint_establish(), it must be called after cpus
attached. module_init_class() is too early to call softint_establish().
--
simplify mutex_enter/exit(crypto_q_mtx), and fix missing exit.
--
reduce rump waring message. pointed out by ozaki-r@n.o, thanks.
