b367c26e41 Add rump_printevcnts() which dumps values from all event counters. 
(NOTE! it is run unscheduled for various experimentation etcetc. reasons)

53d420f9a2 Now that we have a big devsw_conv0, need at least as many entries 
in devsw as the highest device number in the conv table.  Do a
"good for a hundred years" guess now, fix properly later.

99d0de7a5e Remove bpf modload code. With the current state of affairs, the 
kernel module either be autoloaded from the host or the kernel
module ABI is not supported on the given arch.

66708c492e Autogenerate /dev nodes. Use (recreate) the naming policy in 
MAKEDEV. -- Not the famous irrational file system devfs, but an
incredible simulation.

f6d46ec2d9 Include devsw_conv0 from an i386 kernel compilation (no, we don't 
care about the arch as long as all the devices we care about are
present).  The file should be autogenerated, but that requires some
more changes to config(1).

6e3fa8db54 Add translation from vtype to dirent type. Convert rumpfs now. 
I'll convert the rest of the file servers in need after the next
version bump to avoid the coding module crisis.

e7ad158bcf Get better results if initialize a field before calling strlen().

e8ae82c755 p2k asserts get upset if VOP_ISLOCKED() doesn't reflect lock status. 
So let genfs do its thing.

704b1cf6f8 Instead of causing a catastrophic failure when uvm_loanuobjpages() 
is called, just pretend it hit a wired page and return EBUSY.  This
should cause callers to use a non-loaning access path instead.

Fixes file read path of stock nfs kernel module (previously it was
easy to just frob the nfsd_use_loan boolean into the other position
by simple value assingment, but now that nfsserver can be autoloaded
at runtime into the rump kernel, that approach is a little more
challenging since the variable isn't available in application
linkage.  yes, things like adding a sysctl for the variable would
work, but now everything works out-of-the-box).

eb67c195b0 Uncrack my brain, buggy let me !be. 
In other words, make previous commit to this file actually work.
Funny how it's possible to fix things to not dump core and still
have them not work.

c4a03daef5 If RUMP_NCPU is set, use that for virtual CPU count instead of 
host CPU count.

c1cd247fa4 Make initial devsw a little more believable. Especially adjust 
max_sys_devsw, since it was previously a bit too much, given that
the correct value is 0.

... or at least on x86.  CPU_INFO_FOREACH() still isn't MI, and I
don't want to support 2^n different versions.

7c5b388514 Fix off-by-atleast-1 error. 
Note: etfs doesn't work if rumpfs is not mounted as root.  Given
that rumpfs_mount always return EOPNOTSUPP (except for mountroot),
this is not a pressible tragedy currently, but nevertheless
could/should be fixed in the future.

717accdd51 Register module_base as an etfs recursive subdirectory. This means 
that rump will autoload kernel modules from the host
/stand/arch/vers/modules directory.

3ff8b6d009 Add directory support to etfs: host directories and their contents 
will be mapped to rumpfs based on the given key.  The directory
can be mapped either for a single level or recursively down the
entire subtree.

b468e56e8c Implement kobj_renamespace() for rump. Support for a few archs is 
missing, but that doesn't really matter, since they are living in
their own "everything is a macro" happyland and don't support the
native kernel ABI anyway.

445cf1a49a Change machine from "rump" to MACHINE so that module_base goes 
right.

Now, any guesses on how many archs this seemingly trivial change
will break the principal metric, i.e. The Build(tm)?  Keep the bets
coming in.

e4759b9b17 Remove trailing comma in enum, per PR kern/43200. 
(trailing commas in enums are allowed in C99, but not C89, and possibly
not in C++, so let's be nice to older and deviant compilers)

34244e1069 Reduce #ifdef spew by attaching wapbl as a module.

useful and module-like like load into any kernel)

4a383bb8da Move sys_module from vfs to kern -- while modules cannot be loaded, 
there's not forbidden about querying the list of (builtin) modules
even when running without vfs.
