When in list mode, the filenames in the archive are written to stdout.
For pax, POSIX says that *only* the file listing output may be written
there; all diagnostic output must go to stderr. So don't use listf or
listfd to write non-file-listing output.
There's a tricky bit that I'm not sure

pax includes routines for caching getpw{nam,uid} and getgr{nam,gid}
results. Okay, but libc already has caching uid->name and gid->name
routines: user_from_uid() and group_from_gid(). Let's switch pax over to
the libc routines. That'll free up a little space on the ramdisks.

So enabling full hardware-enforced W^X is perhaps a bit to much at
this moment. But enabling the bit that enforces that the kernel
cannot execute pages that are writable by userland should be fine.
The diff does this on all ARMv7 processors that include the
Virtualization Extensions, which is what

I agree that it is preferable to do such bugfixes in consensus, if
possible; that helps to improve quality and coherence.

Looks good. I wouldn't bother with an else after the break but if
you think it reads better that way, that's fine with me.

I'm probably not understanding something here but why can't you
just test for __SEOF in fp->_flags when __srefill() returns non-zero
and treat the absence of __SEOF as an error?

Diff below simplifies ip6_getpmtu() to use a 'struct rtentry *' instead
of two 'struct route_in6'.

Hi,
what happens in fgetln(3) when the buffer runs out and reading more
bytes fails before a newline character is found? There are two
cases:
1. The stdio read buffer is empty at the time of the call,
and the read(2) in __refill() fails:
fgetln(3) returns NULL and sets errno and the std

The pmap_fault_fixup() functions does a number of different fixups:
1. page modified emulation
2. page access emulation
3. entering level-1 entries for level-2 page tables
Since it is a generic function that gets called for many fault types,
it has to be careful to only enter mappings that are
i noticed this when trying to figure out what level a cardslot would
interrupt at.
now we have splraise this is a lot more straightforward.
avoiding an splraise when we're not sure whats actually lower than
IPL_BIO is not worth the effort. splraise to a lower level is fine.
ok?
