riastradh | 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macppc/if_gm.c (superseded by gem(4))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!)

pooka | branches: 1.7.2; 1.7.8; 1.7.16; 1.7.18;
Put the kernelside rump kernel headers into <rump-sys> instead of
sprinkling them around the faction directories. Avoids having
to add a CPPFLAGS (or several) to pretty much every component
Makefile.
Leave compat headers around in the old locations.
The commit changes some autogenerated files, but I'll fix the
generators shortly and regen.

dholland | branches: 1.6.4;
Add d_discard to all struct cdevsw instances I could find.
All have been set to "nodiscard"; some should get a real implementation.

| 16-Mar-2014 |
dholland | branches: 1.5.2;
Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

* implement rump_vfs_makeonedevnode(), where the interface for creating
multiple nodes doesn't make sense: e.g. /dev/null would've had to
be created with ("/dev/nul", 'l', 1)
* implement said /dev/null (just for show)

Resolve a couple of conflicts (result of the uimin/uimax changes)
|

pgoyette | Remove more unnecessary #include for sys/localcount.h
|
| 1.7.8.1 |
| 27-Apr-2017 |
pgoyette | Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).
The branch now builds, and installs via anita. There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.
|
| 1.7.2.3 |
| 26-Jul-2016 |
pgoyette | Rename LOCALCOUNT_INITIALIZER to DEVSW_MODULE_INIT. This better describes
what we're doing, and why.
|
| 1.7.2.2 |
| 19-Jul-2016 |
pgoyette | Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it. This also removes the need for defining new symbols
for each 'struct localcount'.
As suggested by riastradh@
|
| 1.7.2.1 |
| 18-Jul-2016 |
pgoyette | Rump drivers are always installed via devsw_attach() so we need to
always allocate a 'struct localcount' for these drivers whenever they
are built as modules.
