(and make it easier to find stuff for the old ones). I originally put
everything under one "RULE SUBSYSTEM" so it didn't look like devfs(8)
is dedicated to the rule subsystem, but since nobody has any idea what
else might go here, it's not worth confusing people just to save a
little time for someone that might add something rule-unrelated to
devfs(8) in a few years.

ruleset. If we do, that means there's a ruleset loop (10 includes 20
include 30 includes 10), which will quickly cause a double fault due
to stack overflow (since "include" is implemented by recursion).
(Previously, we only checked that X didn't include X.)
/etc filesystem isn't enough; consequently, add "-i 4096" to the newfs
command for /etc. This results in 1022 inodes, which should be enough
for the forseeable future (although I don't know why we would ever
have more than 1000 files in a default /etc).

wasn't sure that the condition in question could arise, so I provided
some example code.

_CPUCFLAGS if both NO_CPU_CFLAGS and NO_CPU_COPTFLAGS were defined
since it is redundant (we don't use _CPUCFLAGS if those are defined).
to tune for more advanced processors while still supporting the minimum
processor in an architecture. We can do this with the '-mtune=' option
to gcc for alpha, sparc64, and powerpc and with the mis-named '-mcpu='
option for i386.
This defaults to tuning i386 builds for i686 machines though not using
any instructions that aren't found on an 80386. For alpha it defaults
to tuning for an EV5.

basically maps all of physical memory 1:1 to a range of virtual addresses
outside of normal kva. The advantage of doing this instead of accessing
phsyical addresses directly is that memory accesses will go through the
data cache, and will participate in the normal cache coherency algorithm
for invalidating lines in our own and in other cpus' data caches. So
we don't have to flush the cache manually or send IPIs to do so on other
cpus. Also, since the mappings never change, we don't have to flush them
from the tlb manually.
This makes pmap_copy_page and pmap_zero_page MP safe, allowing the idle
zero proc to run outside of giant.

implementation. This flag will indicate that the security label
in the vnode is currently valid, and therefore doesn't need to
be refreshed before an access control decision can be made. Most
file systems (or stdvops) will set this flag after they load the
MAC label from disk the first time to prevent redundant disk I/O;
some file synthetic file systems (procfs, for example) may not.

since it breaks mtx_owned() on spin mutexes when used outside of
mtx_assert(). Unfortunately we currently use it in the i386 MD code
and in the sio(4) driver.
