4ce1278ac8 add (void *) intermediate casts to elide gcc function cast warnings. This 
is the simplest solution; choices:
- add pragmas, complex and ugly (need to be gcc-specific)
- add -Wno to COPTS. Needs to be done in many makefiles because of rump
- add intermediate functions: slows down things

edcef67ec2 xc_barrier - convenience function to xc_broadcast() a nop. 
Make the intent more clear and also avoid a bunch of (xcfunc_t)nullop
casts that gcc 8 -Wcast-function-type is not happy about.

cb94f55012 don't always panic when modunload crypto (int the pool destroy code, because 
the pools are busy). XXX: this is still racy; we need to prevent creating
more sessions while destroying.

8c2f80f160 Rename the MODULE_*_HOOK() macros to MODULE_HOOK_*() as briefly 
discussed on irc.

NFCI intended.

Ride the earlier kernel bump - it;s getting crowded.

d1579b2d70 Rename min/max -> uimin/uimax for better honesty. 
These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

attached. module_init_class() is too early to call softint_establish().

d5274e1aa6 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.

2b0e5418a0 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.
