jld 0ebf778b9d The poll routine needs to return POLLERR on error, not an errno. Sorry 
about that.  Pointed out by Juergen Hannken-Illjes in mail.

elad b8a339347f Implement the "device" scope. 
It uses an authorization wrapper per device class on the system to
ensure type-safety.

For now, it supports only terminal (TTY) devices, and has two actions
for them: "open terminal" and "privileged set". Sample usage has been
added to i386 and hp300 code for reference.

Update documentation.

bjh21 e9030bd381 Move over to using the standard ARM bus_space implementation on acorn26. 
This is more flexible than the old acorn26 bus_space, which means that single
read/write operations are slower, but multi and region operations have the
potential to be faster, and particularly insane podules might be supportable.
In theory the acorn32 mainbus and podulebus code ought to be shareable, but
acorn26 needs the extra overhead of saving R14_svc on some operations so
I've made my own version for now.  Also the acorn32 bus_spaces are a mess.

bjh21 213f273e6a Calls to bus_space_barrier() on acorn26 were very few and using constants that 
were two generations obsolete.  Since they do nothing anyway, remove them
rather than trying to update them.

elad 5ec8c535f2 PR/34648: Nino Dehne: Kernel panic when using NFS root and configuring an 
interface that needs firmware

Firmload routines were using FSCRED, which in this case would get to the
NFS code and dereferenced, resulting in a panic. Use the credentials from
the LWP instead.

files that don't have the "indirect" flag. Also change the "library" alias
in veriexecctl(8) to mean "file, indirect".

drochner 429dff1c3d Flush regular files before setattr also if the mode bits are going to 
be set. Linux NFS servers (at least) reset suid/sgid bits if a write
happens afterwards. Add a comment why this is done.
This fixes system builds on diskless systems for me where suid bits
were missing after install(1).
Approved by yamt.

pooka 751537fe38 Make these work again. I know, I'm a bit impatient, since they've 
only been broken for 12 years, but some things are better done
sooner than later.

While meddling here, introduce mp_vchain, which prints the vnode
chain given a mount point.
