- Bump max data size from 2G to 3G. The actual space we are allowed to allocate
is somewhere between 2G and 3G, so trying to allocate above that will fail.
- Bump max stack size from 32M to 64M.

was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.
The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.
Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.
OK'ed by my project mentor, William Studenmund (wrstuden@).
This (just about) counteracts the bloat added by the 64bit inode changes
and the the larger data structures of the new ioconf.c.
The 'st' driver got fingered itself because of it's own size increase
caused by the addition of the stats.
standard scheme:
if (<configured> != <wildcard> && <configured> != <real>)
then fail

This is handled by config_stdsubmatch() now.
explicitely by a plain integer array
the length in now known to all relevant parties, so this avoids
duplication of information, and we can allocate that thing in
drivers without hacks
#define clockframe somethingelse
to:
struct clockframe {
struct somethingelse cf_se;
};
and change access macros accordingly.
That means that, at least for that very issue, things will not go
ka-boomy if you don't have the actual definition of struct clockframe
before including systm.h.
When powersave mode is enabled, the TSC stops counting while the CPU is halted
in idle() waiting for an interrupt. This means we can't use the TSC for
interval time in microtime(9), and thus it is disabled here.
It still makes a perfectly good cycle counter for program profiling, so long
as you remember you're counting cycles, and not time. Further, if you don't
mind not using powersave mode, the TSC works just fine, so this should really
be optional. XXX
